ASUS P5E3 Premium WIFI [email protected]


Today we at Bjorn3D plan to help you procrastinators out there by providing some useful facts that will help with your decision making dilemma. We will be reviewing the ASUS’s top of the line X48 based P5E3 Premium WIFI-AP @n motherboard. We plan to take this review to a new limit by testing the board with both the Intel® Q6600, 65nm processor and the Intel’s new X3350 Xeon 45nm Quad core processor which is said to mimic the long awaited, forthcoming 9450 processor in all respects.



For the last several months there has been quite a bit of discussion amongst the computer enthusiast ranks regarding the Intel® based X48 motherboards. Much of this discussion has stemmed from the release date for these boards being changed a number times. Well the time is here and these boards are finally making it to the mainstream consumer market. Some enthusiasts are saying its too little to late, while others are enthused about the potential these X48 based boards will bring to bear.

Those enthusiasts that are planing an upgrade to an X48 based motherboard are also heavily involved in additional rhetoric in an effort to discern the the best CPU to power this board. The waters have been muddied a bit with regard to this aspect of their thought process as the 45nm Quad processors slated to be released months ago have also been delayed and should be making their way into consumers hands within the next month. Probably the biggest decision is whether to remain with tried and true 65nm Quad core processors such as the Q6600 which is currently extremely cheap or make the move to th 45nm in hopes of significant performance gains from their architecture. The dual core (Wolfdale) version of the Intel® 45nm processor has been available for a while now and equated itself quite well making the decision even tougher.

Today we at Bjorn3D plan to help you procrastinators out there by providing some useful facts that will help with your decision making dilemma. We will be reviewing the ASUS’s top of the line X48 based P5E3 Premium WIFI-AP @n motherboard. We plan to take this review to a new limit by testing the board with both the Intel® Q6600, 65nm processor and the Intel’s new X3350 Xeon 45nm Quad core processor which is said to mimic the long awaited, forthcoming 9450 processor in all respects. We will also test the board using the 64 bit version of Vista using both 2GB of high-speed DDR3 as well as 4GB of lower latency DDR3. While this presentation is first and foremost a motherboard review we hope to assist as well in providing data to help you purchase the right accessories to make it shine.

ASUS:  The Company

ASUS, a technology-oriented company blessed with one of the world’s top R&D teams, is well known for high-quality and innovative technology. As a leading provider of 3C (computers, communications and consumer electronics) total solutions, ASUS offers a complete product portfolio to compete in the new millennium.

In 2006, the company shipped 55 million motherboards, which means one in three desktop PCs sold last year was powered by an ASUS motherboard. Our 2006 revenues reached US$16.5 billion, and is expected to garner US$23 billion in 2007.

ASUS products’ top quality stems from product development. It’s like learning Chinese Kung-Fu; one must begin with cultivating the “Chi” and inner strength.

You can see from your very first glance that the ASUS® P5E3 Premium WIFI-AP @n is no ordinary looking motherboard. While it lacks most of the colorful LEDS and other visual fanfare of its ROG counterpart it makes up for this many other useful features that would appeal to a different type of enthusiast. Don’t let the lack of pomp fool you this board is every bit a performer. As the image below depicts the board is an eye-catcher given its extensive use of copper in the passive cooling elements and is really set off by the cobalt blue northbridge cover with the ASUS logo.


A macro look at the components reveals ASUS has chosen to listen to their users and has used all solid core, high-quality conductive polymer capacitors in lieu of the cheaper, less reliable electrolytic capacitors that have been known to be troublesome on other motherboards. ASUS has also chosen to use their 3rd generation 8-phase VRM power design with this board. This power system utilizes low RDS (on) MOSFETs for minimum switching loss & lower temperatures, Ferrite core chokes with lower hysteresis loss, in addition to the previously mentioned polymer capacitors thus helping to ensure longer component life and lower power loss, creating more energy efficiency.


ASUS has continued it’s use of passive cooling on the P5E3 Premium WIFI-AP @n and taken it to new extremes even for ASUS. The passive cooling element is one continuous product that begins with the PWM on the right rear of the board encircling the entire LG 775 socket and then extending to the northbridge and southbridge. A closer view of the northbridge shows the passive cooling system to be even more substantial than that used on ASUS’s ROG series of boards such as the Maximus Formula. We did notice that the height of the passive cooling unit on the Northbridge might cause some problems for “wide bodied” CPU coolers that didn’t raise the device to around two inches.


The P5E3 Premium/[email protected] also supports 802.11n WiFi specifications onboard for faster data transfers. ASUS Express Gate is also onboard which uses an optional Linux OS bootup installed on a small flash drive on the board for quick access to the Internet in just a few seconds. Express Gate allows you to enjoy commonly used functions like accessing the Internet, VoIP, and Web emailing without entering the OS. This motherboard supports the latest Intel® Core™2 processors in LGA775 package. It also can support Intel® next generation 45nm Multi-Core CPU. With new Intel® Core™ microarchitecture technology and 1600 / 1333 / 1066 / 800 MHz FSB, the Intel® Core™2 processor is one of the most powerful and energy efficient CPUs currently in production.


The P5E3 Premium/[email protected] also supports AMD´s CrossFire which boosts image quality along with rendering speed, eliminating the need to scale down screen resolutions to get the high image quality you want. CrossFire ignites with the higher antialiasing, anisotropic filtering, shading, and texture settings you desire. The motherboard supports DDR3 memory that features data transfer rates of 2000(O.C.)/1800(O.C.)/1600/1333/1066/800 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The dual-channel DDR3 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidths of up to 28.8 GB/s. Furthermore, the supply voltage for the memory is reduced from 1.8 V for DDR2 to just 1.5 V for DDR3. This voltage reduction limits the power consumption and heat generation of DDR3 which makes it a more power efficient, yet powerful memory solution.


The P5E3 Premium/[email protected] features three x16 PCI-e 2.0 ports for support of the latest PCIe 2.0 devices for double speed and bandwidth which enhances system performance. ASUS EPU utilizes new technology to digitally monitor and tune the CPU power supply with improved VR responses in heavy or light loadings. It automatically provides power for higher performance or improve efficiency by 50% when the PC is running low intensity applications. Working together with AI Gear 3+, this can help you attain the best possible power efficiency and energy savings up to 80.23% to help save the environment.


Stack Cool 2 is a fanless cooling solution offered exclusively by ASUS. It effectively and noiselessly transfers heat generated by the critical components to the other side of the specially designed PCB (printed circuit board) for effective heat dissipation – making temperatures cooler by up to 20°C. The Pure Copper Heat Pipe design effectively directs the heat generated by the chipsets to the heatsink near the back I/O ports – where it can be carried away by existing airflows from the CPU or a bundled optional fan. This innovative and groundbreaking fanless heat pipe design effectively lowers temperatures by up to 10°C without having lifetime problems that a normal chipset fan has. Furthermore, it provides options for users to install side-flow fans or a passive cooler. This Heat Pipe design is the most reliable fanless thermal solution to date.


Another very cool feature on his highly feature laden board is AI Slot Detector. When PCI-e/PCI devices are installed, users can simply plug in the power cable and find out if these devices are successfully installed. Without even switching on the PC or entering the operating system, ASUS´s on-board LEDs provide an efficient way to identify the correct way to set up the PC. A red led indicates something is awry while no LED signal indicates that the PCI-e/PCI device is properly installed. How many times would this feature have saved one of us the embarrassment of having to open the case to properly seat a card or to plug in a PCI-e power adapter that we forgot to properly seat?


The BIOS framework for the ASUS® P5E3 Premium/[email protected] motherboard is per usual controlled by the American Megatrends, Inc. BIOS. The features shown in the images below are from the latest BIOS avialable for the P5E3 at the time we began testing, version 0151.

Main BIOS Screen

The Main BIOS screen appears to be no different than that used on any version of any ASUS BIOS that we’ve seen over the past year. The features here are self explanatory and we won’t insult your intelligence by reviewing each of them.


Extreme Tweaker BIOS Screen(s)

The Extreme Tweaker BIOS screens include all the features relevant to the entire board’s system frequency,memory and voltage, in other words all of the overclocking features are located here. It is quite large and requires several images (below) to be able to view all of the included features.










Advanced BIOS Screen(s)

The Advanced BIOS screens contain options for changing: CPU configuration, USB devices, AI Net 2, Northbridge configuration, on-board devices, and Plug and Play options.





Power BIOS Screen(s)

The Power BIOS screens allow you to change settings for advanced power management and ACPI. Probably the single most interesting feature here is the Hardware Monitor which literally monitors either the RPM, temperature, or voltage on almost every phase of your boards operation. These values can be displayed on screen using the latest version of ASUS Probe II software included with the board on the utilities disk.



We add the next table on the vast majority of our motherboard reviews for the both the computer enthusiast and for the general consumer to use for comparison purposes. The table depicts all of the primary BIOS parameter ranges that would be of interest to anyone thinking of overclocking this board.

Test Methodology

As we alluded to in the introduction, we decided to test the ASUS® P5E3 Premium/[email protected] using both the Intel® Q6600 65nm Quad processor and X3350 45nm procesor to see just how much variance there is between the two CPUs. We ran the Q6600 using a multiplier of 8 and a FSB of 333 to mimic the X3350 as much as possible for this heads-up comparison. We also tested the X3350 utilizing the ASUS Maximus Formula motherboard to get a direct comparison between the X38 and the X48 based motherboards. It should be noted though that the Maximus Formula uses DDR2 as opposed to DDR3 on the P5E3. We assembled a group of benchmarks, captioned below that we feel are readily accessible and more importantly free to the public sector for our testing, We feel the benchmarks chosen when completed will be representative of this system’s complete performance. You will also note that we ran all of the tests that were specific to 64-bit Vista operating system utilizing the recently released SP1. We also utilized both Dx9 and Dx 10 for our gaming and GPU tests. All benchmarks were run a minimum of three times and an average of the results were posted.

Unfortunately when testing a motherboard there is not set of “grass roots” tests that will speak to the motherboard’s overall performance. It is therefore necessary to comparatively test the performance of the CPU, Memory, Hard Drive(s) and Graphical Rendering and then we’ll draw assumptions from the results of these tests.

The measurement unit “3DMark” is intended to give a normalized mean for comparing different GPU/VPUs. It has been accepted as both a standard and a mandatory benchmark throughout the gaming world for measuring performance.




Company of Heroes(COH) is a Real Time Strategy(RTS) game for the PC, announced on April, 2005. It is developed by the Canadian based company, Relic Entertainment, and published by THQ. We gladly changed from the first-person shooter based genres of the rest of our gaming benchmarks to this game which is RTS. Why? COH is an excellent game that is incredibly demanding on system resources thus making it an excellent benchmark. Like F.E.A.R. the game contains an integrated performance test that can be run to determine your system’s performance based on the graphical options you have chosen. It uses the same multi-staged performance ratings as does the F.E.A.R. test. We salute you Relic Entertainment!




Crysis is the most highly anticipated game to hit the market in the last several years. Crysis is based on the CryENGINE™ 2 developed by Crytek. The CryENGINE™ 2 offers real time editing, bump mapping, dynamic lights, network system, integrated physics system, shaders, shadows and a dynamic music system just to name a few of the state of-the-art features that are incorporated into Crysis. As one might expect with this number of features the game is extremely demanding of system resources, especially the GPU. We expect Crysis to be a primary gaming benchmark for many years to come.




Power conservation appears to be a current mission for the vast majority of motherboard manufacturers, and with good reason. It is our opinion that the trend over the last year of having to buy huge, and in most cases extremely expensive power supplies to make your system perform up to its peak is not the direction we need to be headed in. ASUS has made a commitment to help keep power demand low on your system when you don’t need peak performance and for most users that would average between 70% – 80% of the time. ASUS makes the following statement concerning their efforts with the ASUS P5E3 Premium WIFI [email protected]:

“The ASUS EPU utilizes innovative technology to digitally monitor and tune the CPU power supply with improved VR responses in heavy or light loadings. It automatically provides power for higher performance or improve efficiency by 50% when the PC is running low intensity applications. Working together with AI Gear 3+, this can help you attain the best possible power efficiency and energy savings up to 80.23% to help save the environment.”


To test these claims we the AI Gear 3+ drivers which work in conjunction with the AI Suite of utilities. It should be noted that for this utility and the drivers for AI Gears 3+ to work correctly all BIOS settings should be set to Auto. The first image you see below is the AI screen with all settings unchanged:

AI Suite in Normal Mode


Next we opened the AI Gear screen and opened the accompanying energy savings calculator to see what savings if any normal mode would yield.

Energy Savings Calculator Showing Normal Mode


As we expected there are no energy savings in normal mode. We then adjusted the AI Gear 3+ to the highest energy savings and again took a few of screen shots to show the results detailed in the images below.

AI Gear 3+ at Highest Energy Savings


AI Suite Depicting Highest Energy Savings


Energy Savings Calculator Showing Highest Energy Savings


In the two energy saver screen images we see almost an eleven Watt savings at idle, not shabby at all. Now if this were a static process and not dynamic you would be severely hampered in day to day operations should your need for speed increase. Thankfully ASUS realized this and built the software in such a way that the CPU power is constantly being monitored and adjusted to meet your needs. Now for the ultimate test we chose to run benchmarks with Crysis which we all know is one of the most highly demanding games on system resources. In the graph below we compare the differences utilizing the energy savings feature and running your system in normal mode.


As we can see there is less than a 3 FPS drop in the game’s average frame rate which actually surprised us as we were expecting it to take a bigger hit. We repeated the test numerous times and continually got the same results give or take a few tenths of a watt. For the potential energy savings this utility offers we will gladly sacrifice 3 FPS on any game any day.


Now on to our favorite area of any review, overclocking. We’ll admit that after reading a number of previews of the ASUS P5E3 Premium WIFI [email protected] where either the Intel® E8400 or E8500 Wolfdale processors were overclocked to rather extreme levels we were expecting similar performance from the Intel® X3350 quad core. We decided to also overclock our Q6600 for comparison purposes. After a couple of hours of playing we reached an FSB of 447 yielding an effective overclock of 3.576 GHz this was achieved utilizing the chip’s stock multiplier of 8. This was the highest attainable overclock we were able to reach no matter what we did on both processors. We tried increasing the FSB some 20 MHz higher in case there was an FSB wall, increasing all voltages, changing the multiplier and running a higher FSB, and adjusting every other BIOS setting that we felt would help to improve this mark. Nothing did! Strangely enough we encountered the same identical issue with the Q6600 and were also unable to move beyond the mystical FSB of 447 also using a multiplier of 8. This was in the same stable max clock range that we experienced when testing the Q6600 with the Maximus Formula.

We even tried changing the memory strap and found no differences in our ability to overclock at either the 1333MHz strap or the 1111MHz. The only difference we found between the two straps was that we had to change to our 2 GB kit of Patriot Viper DDR3 1500 memory to benchmark at the 1300MHz strap as the OCZ 4GB kit we were using would not boot at 1788 MHz which was the effective memory clock using this strap. To achieve this degree of overclock with the X3350 we used a VCore of 1.30V, a Northbridge setting of 1.5V, and a VDimm of 1.9V, with the Q6600 we had to use a VCore of 1.425 and the same settings for the Northbridge and VDimm. Below you see our results:

OC 447 FSB at 1111MHz Memory Strap


OC 447 FSB at 1333MHz Memory Strap







In all our years of overclocking we experienced some very strange issues in this benchmarks we ran after achieving our maximum overclock:  1)  We would have expected much higher 3DMark06 scores at this level of OC; and 2)  We would have expected better performance from the higher memory strap on all tests. We have a number of ideas why, but those that we feel are the most accurate entail:   1) We are using the newly released SP1 with Vista 64 Ultimate and it doesn’t seem as fast; 2) The fact that the OCZ memory was both a 4GHz kit and had lower latency than the Patriot memory attributed to the higher scores although not significantly higher. We will delve much deeper into the memory performance as we intend to do extensive reviews on both the OCZ DDR3 12800 Platinum and the Patriot Viper DDR3 15000 in the very near future. We’re not a huge fan of Vista and still feel that many of the issues we and others are experiencing are Vista related. At this point given the infancy of this motherboard’s BIOS and the fact that it performs at the top of the heap with the dual core Wolfdale processor we can only surmise at this stage in the game that it’s not as friendly toward the quad core processors as we’d like to see.


The ASUS P5E3 Premium WIFI [email protected] is ASUS’s top of the line X48 motherboard that currently retails in the $350.00 to $400.00 USD range. It is highly feature laden and in our testing all of the features worked as advertised which is quite exceptional in today’s market. The board is extremely well built using only the best components as it should be for the price that you are paying. The P5E3 Premium coupled with the Intel® X3350 Core 2 Quad processor yielded excellent results in most of the non-overclocked benchmarks that we ran, especially those relating to memory.

The layout of the ASUS P5E3 Premium WIFI [email protected] is among the best we’ve seen with the possible exclusion of the tight confines around the socket 775 which may cause problems for some wide bodied coolers that don’t have the height to clear the passive cooling elements. We also found the audio to be subjectively the best we’ve experienced from an on-board solution. The Express Gate is a great feature that allows the user access to the Internet without the need to boot the boaard’s full operating system. The only drawback of Express Gate is that it doesn’t provide the space to download and retrieve a necessary component you might need in an emergency.

While we are aware that many enthusiasts do not have power consumption in the forefront of their minds, we, however begrudgingly, realize its an eventuality that we all must face. The ASUS EPU utilizing the Ai Suite and the AI Gear 3+ control panel and drivers does an excellent job of conserving energy without sacrificing much in the way of performance. We also realize that the cost of this board may preclude it from some user’s consideration. Overall performance was quite good in most cases besting the X38 by 15% or more which is significant.

The only real downside to P5E3 is that in its present state it does not overclock the Core 2 Quad processors as well as we would have hoped for. This presents a bit of a conundrum as we’ve seen a number results showing it to be one of, if not the best overclocking boards available when using the Intel® Core 2 Quad 45nm Wolfdale processors.  After doing a bit more research we find that almost everyone is experiencing the FSB limitations similar to ones reported in this review with the 45nm Core 2 Quad cores.   For that reason we certainly can’t fault ASUS in the design of this board.  We can recommend that if you want premium results with this board and apparently many others, the 45nm Wolfdale would be the processor of choice; not to mention saving you a fe $$$ in the process.

When it comes to recommendations we find this board to be in a league of its own from the standpoint of features.  The X48 P5E3 Premium does outperform our Maximus Formula X38 board by an average mark ranging from 12%-15%.  Whether that is enough of a performance increase to justify the expense of this board is a question you’ll have to answer for yourself.  From our standpoint at Bjorn3D it will be one of the boards that we class as a “keeper” and one we’ll use regularly in future reviews.
