ASUS P5K3 Deluxe WIFI AP Edition

The ASUS P5K3 Deluxe is a high-end P35-based that not only comes with all sorts of fun features but also turns out to handle fast DDR3 memory well.


I recently reviewed the ASUS P5K3 Premium motherboard. This is a motherboard where ASUS’s engineers have gone all out and integrated 2 GB of good DDR3 memory directly on the motherboard. You can read my review here. As you can see in that review it was a motherboard that did a lot of things right but got docked a few points because of the limitations you get when putting expensive memory directly on the motherboard.

The ASUS P5K3 Deluxe that I am reviewing today is basically the same motherboard, but without the integrated memory. My expectations of the motherboard were naturally high as it theoretically would be just as good as the Premium, but without the disadvantages of the integrated memory. Did it meet my expectations?


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.

I unfortuantely do not know what kind of box the ASUS P5K3 Deluxe comes in. The box I got from ASUS turned out to be the inner box lacking the outer kartong “shell”. This sometimes happens when you get sent a old review unit. I expect the retail product to have a regualr blue, black or maybe green look with some info about the motherboard on it. We all know how they look, don’t we? I was pleasantly surprised though that even though the box looked a bit shabby the motherboard inside had survived all the trips to different reviewers without any issues at all.

The box

Opening the box we see a familiar sight: the ASUS Deluxe/Premium bundle. ASUS packs the box with all sorts of items that you need for the motherboard.

  • The motherboard
  • UltraDMA 133/100/66 cable
  • FDD cable
  • 6 x Serial ATA cables
  • 1 x 2-port Serial ATA power cable
  • I/O Shield
  • User’s manual
  • ASUS WiFi-AP Solo manual
  • 3 in 1 Q-connector
  • 1 x 2-port USB2.0 / 1-port IEEE1394 module
  • Optional Fan for Water-Cooling or Passive-Cooling only
  • ASUS WiFi-AP Solo omni-directional antenna
  • CD with drivers and software

If you read any of our other ASUS motherboard reviews you now know what to expect of the bundle.


The Q-connector is as useful as always making it easy to hook up your case to the motherboard


As with all their high-end motherboard that uses a copper heatsink to remove heat from the north and southbridge, ASUS includes a small chipset fan that can be used if you are using water cooling on the CPU. The reason is because the heatsink actually needs the CPU fan to remove heat from the heatpipe.

Last but not least we again find the ASUS WIFI-antenna that is connected to the internal WIFI card (.11G only).


The motherboard is all black and quite similar to the P5K3 Premium. The main feature is the big copper heatsink with heatpipes that runs from the north and southbridge to two larger heatsinks around the CPU area.

The rest of the layout is pretty much the same as we come to expect from P35-motherboards from ASUS. The various connectors sit around the edge of the motherboard making them easy to reach. The first PCI-E 1x slot sits close in line with the heat sink but as long as you do not put a fan there a long PCI-E 1x card should still fit there. The CMOS-battery sits a bit awkwardly and will be obstructed by a larger video card. Luckily you should not have to clear the CMOS by removing the battery often anyway. The PCI-E 16x slots have a small led which lights up when you start inserting a card and then turns off when the card is firmly inserted. It is a nice idea that helps you make sure that the video cards are firmly inserted.

I did encounter a minor issue with the EIDE-connector while running two HD2900XT in Crossfire mode. The cooler of the second HD2900XT lay over the EIDE connector pushing the IDE-cable down. The cable I used turned out to be a bit to in-flexible making it hard to get the HD2900XT seated properly so I had to find another one which worked better. Neither SATA-connector were affected by the long HD2900XT cards though so my problem is one very few would encounter. 

The 6 internal SATA-ports are clustered at the front edge of the motherboard, close to where you usually find the hard drives in a case. The only IDE-connector sits close to the SATA-connectors.

As with the P5K3 Premium ASUS unfortunately has chosen not to include on-board power and reset buttons. A regular user can live without those, although they are great for us tinkerers, but an even bigger omission is that there is no Clear-CMOS button which you find on many other motherboards.

At the back of the motherboard we find the following I/O-ports:

1x PS/2 Keyboard
1 x S/PDIF Out (Coaxial + Optical)
2 x External SATA
1 x IEEE1394a
2 x RJ45 port
6 x USB 2.0/1.1
1 x WiFi-AP Solo antenna jack
8-channel Audio I/O


As this has the WIFI AP Solo you have to make due with the connectors directly back on the motherboard instead of the SupremeFX II add-on card that many other high-end ASUS motherboards have. Both still however use the ADI® AD1988B 8-channel High Definition Audio CODEC for the HD-sound.

As the P5K3 Deluxe supports Crossfire it has two PCI-E 16x slots. I am a bit unsure what speed the second PCI-E 16x slot runs though as the specifications claims one of the slot runs at 16x while the other runs at 4x or 1x.


The ASUS P5K3 Deluxe has a similar bios as all the other ASUS motherboards, and as far as I can exactly the same as the ASUS P5K3 Premium motherboard. The bios comes from AMI and has all the features that you expect from a high end motherboard these days.

– Take control of how much power is going into the memory modules. This motherboard gives you 13-step voltage control to the DIMM. 

– Find out “exactly” how much power your CPU needs. Fine-tune it with 0.0125 volts at a time!

SFS (Stepless Frequency Selection) allows
– FSB tuning from 200MHz up to 800MHz at 1MHz increment
– Memory tuning from 667MHz up to 1333MHz at 1MHz increment
– PCI Express frequency tuning from 100MHz up to 150MHz at 1MHz increment

Unfortunately most of the settings are not explained, neither on screen nor in the manual making it hard to know which to change when you are having issues while overclocking. I wish ASUS and other motherboard makers would consider adding more information/examples so that overclocking does not have to be a black art only know to a selected few. 

ASUS includes a few cool features for the overclocker. First you can save up to 2 different presets in the bios. This means you can have one aggressive overclocked setting and one regular and switch between them. Next we have the C.P.R (CPU Parameter Recall) which brings back previous working settings if a overclock fails during startup. Maybe this is why ASUS choose not to have a Clear CMOS button on the motherboard as they probably think it is not needed. C.P.R  obviously does not work if the machine boots into Windows and you then find stability problems there.

SiSoftware’s SiSoft Sandra has long been a favourite amongst reviewers for testing and benchmarking components in a system. The program allows you to test each component separately and while the result of course only gives a theoretical performance it none-the-less allows you to spot any bottlenecks in the system.


As expected there is not a lot of difference between the various motherboards. The P5K3 Premium running with the memory at 1500 MHz has a slightly overclocked CPU which is why the score is slightly higher.


Compared to the other motherboard with regular external memory, the Gigabyte P35-DQ6, the P5K3 Deluxe scores slightly less in the memory test. The integrated memory on the P5K3 Premium has an edge over both the P5K3 Deluxe and the Gigabyte P35..

Hard Drive transfer speed

We tested the performance of a hard drive using three different interfaces: internal SATA, external USB and external eSATA. An AC Ryan external hard drive ensclosure was used for the USB and eSATA drives.

All motherboards perform similarly. The Gigabyte P35 motherboard has a slight edge although it is minor.

Testing the drive using the USB 2.0 interface we see that there is basically no difference between all motherboards. Since they all are using the same chipset it is not surprising.

More and more motherboards now support external SATA-drives making it interesting to see how the performance is. As expected the performance is far more impressive than using the slower USB 2.0 interface. While we do not reach the same performance as we would hooking it up to an internal SATA-port it still is a fast way to connect an external drive. It is possible that the difference in speed also sits in the AC Ryan enclosure. The only result that stands out is the Buffered Write test with the overclocked P5K3 Premium.



PCMark05 has been with us a long time now. Futuremark has started to advertise the next version of this benchmark so this probably will be one of the last times we will see this in use for these newer motherboards. It still is a very good benchmark testing each component in the system with various ‘real-life’ like benchmark situations.

As expected the differences between the motherboards are minor. The P5K3 Premium performs a bit better in the memory category than the other motherboards again highlighting the benefits of integrating the memory.

Everest Ultimate 2006 Edition

Yet another system testing software that also has some benchmarking capabilities. While the tests do not seem to be as thorough as PCMark05 or SiSoft Sandra (they take just a few seconds to run) they none-the-less should provide us with yet another way to spot any obvious bottlenecks in the systems.

These tests really show some strange results. For the Gigabyte motherboard I noticed that the CPU never switched to full speed when running the Photoworx and the ZLib tests. Even though SpeedStep is turned off in the bios, all motherboards run the CPU at 1600MHz in Windows Vista, occasionally switching to 2400 MHz (seen in CPU-z). As a program/game is run that requires more CPU usage the motherboards start running the CPU at 2400 MHz. What I noticed was that the Gigabyte P35 motherboard never switched up to 2400 MHz in the Photoworx and ZLib test, thus yielding much lower results than the other motherboards. It looks that the same thing also happened for the P5K3 Deluxe.

Just as with the CPU test, the Gigabyte P35 motherboard for some reason refused to kick the CPU into high gear during the tests.

The ASUS P5K3 Deluxe manages to beat the Gigabyte P35 in the memory tests while falling behind the P5K3 Premium with its integrated memory.

The latency is slightly better on the P5K3 Deluxe than the Gigabyte P35T-DQ6 while falling short of the P5K3 Premium.


Cinebench 10

Cinebench 10 is a real-world test suite that assesses your computer’s performace capabilities. MAXON CINEBENCH is based on MAXON’s animation software CINEMA 4D, which is used extensively by studios and production houses worldwide for 3D content creation.

MAXON CINEBENCH runs several tests on your computer to measure the performance of the main processor and the graphics card under real world circumstances. The benchmark application makes use of up to 16 CPUs or CPU cores and is available for Windows (32- and 64-Bit) and Macintosh (PPC- and Intel-based).

No surprises here. Overclocking the CPU helps the performance.

SuperPi Mod 1.5XS

This little piece of software calculates from 16K to 16M digits of pi. This stresses the both the CPU and the memory subsystem.


Unless you overclock the CPU you will not see much differences between the motherboards.

WinRAR 3.71

I created two archives with WinRAR 3.71 and recorded the time it took to create them.

Archive 1: Folder with all the files for Cinebench 10. Total Size: 123 MB.

Archive 2: DivX video (Stargate Atlantis). Size: 349 MB


It is interesting to see that the un-overclocked P5K3 Premium manages to perform >10% better than the other two motherboards. I can only conclude that the improved memory subsystem of the P5K3 Premium affects the overall performance for this type of action.

HDTach 3.11 RW

Just as with Sandra, we tested the hard drive performance with HD Tach RW on an interal drive, a drive hooked up through USB and a drive hooked up through eSATA.

Just as SiSoft Sandra showed us, there is no real difference between the motherboards when it comes to SATA-performance.

The same can be said for USB performance although we see that the Gigabyte manages to score a slightly higher Burst performance.

And last but not least the eSATA performance is basically the same on all motherboards. The conclusion is that if transfer rates are important for you, every one of these motherboards will perform fine. 


Last but not least we come to our only game in this test. Gaming performance rarely is affected by the motherboard, instead depending more on the CPU speeed, the memory speed and the video card.

To take the video card out of the equation we ran the built in benchmark in Company of Heroes at 800×600 with all settings set to medium.

As expected the performance is pretty much identical between all the motherboards. The only place we see a slight difference is on the minimum framerate but anyone who has benched this game knows that that score can vary a few fps up and down between tests. The only verifiable difference is that the overclocked P5K3 Premium manages a few extra fps on the minimum framerate.


The ASUS P5K3 Deluxe is an excellent overclocker. I used this motherboard in my review of the Corsair DOMINATOR TWIN3X2048-1800C7 DDR3 memory. In that review I managed easily to get the FSB up to 450 MHz and run my Q6600 stable at 2700 MHz (450×6). I even got it up and running at 475×6 MHz (2.85 GHz) but at that time I started to get some “Display driver stopped responding” errors in some benchmarks.

Here are some of the scores I got out of the motherboard with the CPU and memory running at different speeds.

Half Life 2:Lost Coast

The HardwareOC benchmarking program was used to test the system with the game. 4xAA and 8xAF was turned on and the rest of the settings were set to high quality. HDR-rendering was turned off.

We have seen in other memory reviews on this site that the Half Life 2 engine really likes faster memory. My own test confirms this. While the benefit of faster ram shrinks as we increase the resolution it is quite clear from the results that there is a clear benefit at the lower resolutions up to 1024×768. Remember that the 1800 MHz and 1900 MHz results also has a faster CPU helping with the performance. At 1600 MHz, a 50% increase in memory clockspeed results in a 10% increase in framerate.  

Company of Heroes v1.7

The built-in benchmark in the full game was used. All settings were set to high. AA and AF was turned off.


In contrast Company of Heroes does not really benefit at all from faster memory or even faster CPU. I am aware that the scores might be hard to read but this was left intentionally so you can see how close the performance is even at 800×600 where the GPU will not be the limiting factor. In fact, we even see that the higher the memory clock, the lower the performance at 1600×1200. It it not a huge difference but it is there.


If it was hard to come to a conclusion and score for the P5K3 Premium, it is much easier for the ASUS P5K3 Deluxe WIFI AP Edition. Overall I cannot really see any major flaws with this motherboard. It has a great bundle, great layout, good fan-less cooling (and a optional fan if needed) and overclocks very well. There really are only two minor issues with this motherboard:

1. Just as ASUS other premium motherboards this has a quite high price at around $240. Comparable motherboards from other companies, like the Gigabyte P35T-DQ6 I compared the motherboard with, cost just as much though so it is more a fact that the high end P35 motherboard cost much. As new X38-based motherboards are released I expect the prices to come down on these P35-motherboards.

2. New X38-based motherboards are on our door-step. These motherboards will natively support even faster memory (1600-1800MHz) compared to the natively supported DDR3-1300 MHz in the P5K3 Deluxe. As this review has shown though, the ASUS P5K3 Deluxe however still does handle 1800 MHz memory just fine.

These minor issues aside, the ASUS P5K3 Deluxe WIFI AP Edition motherboard is a excellent motherboard well worth buying if you need a stable and good motherboard for your new C2D or C2D Quad CPU.


+ Excellent performace
+ Great bundle
+ Wireless AP included
+ Great overclocker
+ Has no problems with memory running at 1800 MHz


– Pretty expensive
– Wireless AP “only” 11.g
– New X38 based motherboards should be out soon

The ASUS P5K3 Deluxe WIFI AP Edition gets a rating of 9 out of 10 paws and a Bjorn3D Seal of Approval.
