Breaking News


ASUS has brought to us another ROG series motherboard. And proving once again do not under estimate the GENE series motherboards size. Dynamite comes in small packages.


Earlier this year (2009) ASUS introduced a motherboard that has all of the capabilities, and features that only the full sized counterparts had. These motherboards were all based upon the micro-ATX standard design, during my time using these micro ATX motherboards these little “Bad Boys” quickly became known as the “Mini Monsters” around these parts. In short not only did they keep up with there full sized brethren, they were able to out clock and in some cases out perform full sized motherboards.

These motherboards were known as the ROG (Rebuplic Of Gamers) series GENE, they still carried their bigger brothers name ie. Rampage II, Maximus II. Today ASUS, adds another one of these “Mini Monters” to their line up. I am proud to bring you ladies/gents another ROG GENE motherboard, the ASUS Maximus III GENE.

This time the Maximus III GENE motherboard is based on the ever popular (and cheaper) Intel Socket 1156 CPU. With my past experiences with the previous GENE motherboards that I personally played with, I have high hopes for this little motherboard. I got a feeling I will not be disappointed. Lets break out “Minor Me” and throw in my ever cranking Intel Core i5 750 CPU, in the Maximus III GENE and find out exactly how far I can crank the CPU.

Hope you are ready for a big list of motherboard specifications and the unique features that ASUS packed into this micro ATX mothebroard.

The packaging of the ASUS Maximus III GENE motherboard looks identical to the last three GENE motherboards. But this time ASUS has a windows 7 ready sticker on this one. Like most other P55 chipset motherboards this motherboard supports ATI Crossfire and Nvidia SLI Multi GPU configuration.

Opening up the packages top lid. This part of the box gives us the advanced features of the Maximus III GENE motherboard.

On the inner side of the lid of the packaging is more features this motherboard supports. The Memory OK button been renamed to the Go Button. This helps the motherboard reconfigure itself in case there is a memory compatibility problem.

How ASUS packaged up the motherboard inside of the box. Again identical to how the other two GENE series motherboards are packaged up.

I removed the motherboard box tray to see what comes bundled with the Maximus III GENE.

Everything that is bundled with the ASUS Maximus III GENE. We get an instruction booklet (driver disc inside of the manual), A large ROG sticker, SLI ribbon, an rear IO back plate cover, front IO quick connectors (this makes organizing these plugs into a much simpler design. An USB cable? (have to look this one over.) A bag of wire ties, and finally six SATA cables. What no LED Poster? That’s odd, the last two GENE motherboards had a LED poster included.

Finally the motherboard out side in all its glory, this motherboard is one sexy motherboard. Just giving this motherboard a quick look over, it appears that there is plenty of room around the CPU socket area, the PCI-E ports are in the correct spot, overall so far a nice an clean layout.


Starting off on where the EPS CPU power plug is at. ASUS moved this power port a little bit towards the edge of the motherboard, instead of placing it directly behind the rear IO ports, you still may have some issues reaching this port once it is in a chassis, but it should not be that rough like it used to be to gain access to this power plug (be chassis specific). The GENE motherboard uses a 10 phase power distribution for the CPU, then right behind the chokes are two heat sinks that keep the power mosfets cool during our heavy overclocking adventures. Near the bottom left hand corner we see fan header #1, counting as I see them.

Moving our way down the backside of the motherboard. ASUS uses two PCI-E x16 ports (long red ports) separated by a x4 PCI-E port. The two PCI-E 16 ports will run x16 x 1 or while in multi GPU mode these will be reduced to a 2 x 8×8 configuration, Fallowed by a single PCI port. in the far corner we can see the Supreme X-FI controller chip cover. Right above the first PCI-E 16x port is the Clear CMOS battery, this is in a good spot to get access to. Now turn our attention down toward the bottom edge of the Maximus III GENE motherboard, ASUS places the front IO audio header towards the back end of the motherboard, fallowed by a onboard audio header jack, a 1394 fire wire jack, then we can see fan header #2. The big red button you see is the onboard on/off button. Even if I had two video cards on the this motherboard access to this should be real easy.

Now lets move down towards the PCH (P55) chipset. Starting up toward the upper corner we see the onboard power button and the onboard reset button. moving our way down we can make out an overclocking station port, I have no idea what this port is for because this control was not included. fallowed by three front USB headers, then finally the front IO on/off reset switches, power/HDD LED header. Right above the front IO header is fan connector #3. ASUS even changed the PCH heatsink, I kinda like this new style heatsink design just to bad it be covered up by the first video card. Then right below the PCH chipset are the 180° SATA ports. there is a single 90° SATA port between the 180° ports and the front IO header. Oops, I forgot about fan header #4 that is right below the memory DIMMs.

Looking at the DIMM ports of the Maximus III GENE motherboard, since the 1156 socket CPUs only support dual channel, ASUS only includes 4 memory DIMMs. We can see the main 24 pin power plug, then right above the memory DIMMs is fan header #5. Now what are those little solder pads for I wonder?

The Go button (or Memory OK switch) is located just before the main 24pin motherboard power plug. After thumbing my way through the instruction manual, I found out these solder pads are indeed real time voltage check points. May wanna be careful with the multimeter probes with these, because they do sit really close to one another. Finally I can stick my probes into something, lol.

Looking over the CPU socket area, there does not seem to be any major obstacles in this area, so the use of large CPU coolers should be ok.

Like the other GENE motherboards ASUS includes an LED warning system for when we start cranking the voltages of our components. These light up the same color as the other GENE motherboards (green good, amber High, red crazy) this is the location of the CPU warning LEDs. If you look right below the power mosfet heat sink we can see the OP temp 1 probe hook up, for if you have an extra temp probe to hook up to this motherboard, I did not see any other temperature probe hook ups.

The PCH LED warning system is located right above the PCH heatsink.

The memory warning LEDs are located right above the first DIMM memory port.

Time to look at the rear IO ports of the Maximus III GENE. Starting off on our right then moving left, ASUS gotten rid of the two PS2 ports and replaced it with the single PS2 port with two USB header. Now this is definitely an welcome sight, while most P55 based chipset motherboards dropped the rear clear CMOS button ASUS kept this as standard on their motherboards. Then we are greeted with 2 more USB header, an Audio Opticle out, fallowed by a power USB/1394 Firewire/E-SATA header, 1 Ethernet with two more USB header. What fallows next is a rather strange looking button with a sideways USB port, hmm I wonder what this is for? Then finally the eight channel audio ports.

Looking more closely to this strange new button on the rear IO ports, this is an ROG connect from what I read from the manual, it will allow you to connect to this motherboard remotely to monitor various functions.

The PCH heatsink, now I thought this needed to be pointed out. The heatsink that ASUS used is not the standard everyday fin design, instead ASUS used a block of aluminum as a heat sink. Not saying it is bad, just odd, because during my use of the Maximus II GENE motherboard not once did the PCH get even warm.


Just various pictures of the ASUS Maximus III GENE motherboard.


I just had to get another picture of the Maximus III GENE motherboard all naked like before installation.

Like always I start off with the retention plate. This is how I prep the retention plate prior to installing the water block, I will always use a retention plate on my CPU coolers.

Installed the retention plate onto the motherboard.

Now since the retention is in, it is time to start securing it.

First up is the neopreme washers to protect the Maximus III GENE motherboard surface.

From the steel nuts I am about to use to fully lock down the retention plate to the motherboard. This will ensure that the retention plate and motherboard are one unit, also keep the Maximus III GENE from being bowed once the water block gets placed.

Time for the CPU to get placed onto the motherboard.

Bingo, the polished Intel Core i5 7509 CPU is in and ready to get a work out.

Memory installation as always, is easy to install onto ASUS boards, ever since ASUS went with a metal spring clip on one side and actual locks on the opposite side.

Line up the notches and slides, then press down. Easy as pie.

All done.

Now it is time for chassis installation, since I am using a Raven RV02 chassis, the board will be mounted somewhat different from what you are used too.

Time for the Modified Danger Den MC TDX water block.

I use neoprene washers on the block top as well to help protect the top, from the brass thumb nuts.

Well since one of my neoprene washers wandered off, (I think it gotten scared, you wuss of a washer get back here, lol) So I found a steel one for use in its place.

Just placing the brass thumb nuts on to the water block to secure it properly.

What the motherboard looks like once installed. The video card I used is a EVGA 275GTX.

I almost forgot about the voltage check points. Hooray, I get to use my multimeter.

Time to start sticking these somewhere on the ASUS Maximus III GENE motherboard. Does it really mater where? If you want to kill a perfectly good motherboard, then I guess it doesn’t.

For me I need to keep the ASUS Maximus III GENE board alive. So starting off on the ground probe I will not be placing this no where near the motherboards ground points. Mainly because the pads on where you check the voltages at, to me anyways, are way to close for comfort.

Instead, I will find a unused molex power plug.

Then stick the ground probe into one of the two ground wires of it. Molex power plugs have two grounds in the center of the plug, a ground is a ground no matter where it comes from.

Now its time to start using the positive probe. See it is so much easier doing it this way, then having to hold two probes and at the same time while also trying to read the multi meter.

The positive lead on the pad is designated by a square looking pad, or by a thick white line on one side of the check point. If you do the checking like I did, and you manage to check to ground point you will just end up with a 0 on your multi meter and nothing will happen to the motherboard.

The BIOS Part 1

These BIOS screen shots are only here to give you what the BIOS of the Maximus III GENE motherboard is laid out. I will not be going into great detail of the BIOS itself as most are self explanatory.

I skipped over the Overclocking bit of the BIOS itself that will be posted on the next page. The rest of the BIOS is pretty much the standard lay out we have all grown accustomed to from ASUS. ASUS does an exellent job on grouping up the BIOS itself into sub catagories, for the user to easily access a peticular setting. Anyone should not have a problem on navigating the BIOS at all. ASUS also includes a save profile page where we can save all of our specific motherboard adjustments, this makes loading and saving these profiles effortlessly.


Once again no real need to go into an all in depth overview of the BIOS but I will explain some of these adjustments if it is needed. This is the first BIOS page you come to once you enter the BIOS, this is also where we can tweak the Maximus III GENE to its absolute maximum capabilities.

Once again I am not disappointed by ASUS BIOS adjustments, there are plenty of adjustments also ASUS does a great job on giving us the current settings that are being used, for us to better fine tune the motherboard. ASUS also gives us an ability to up scale our CPU’s (designated CPU core speeds) set the XMP profile of our memory, gives us a boat load of memory timing adjustments, to finally giving us users a fairly fine tuning on our voltages. The only area I thin ASUS could have done better was the BIOS warning colors on the memory, in order to get the proper performance out of our memory we need to be at 1.65 volts, the BIOS gives us a Yellow warning on the memory once it is set to 1.64 volts. oh I should mention that so far out of five different P55 motherboards I still don’t have a 1.65 memory voltage setting. I think ASUS and other manufacturers should include the 1.65 voltage setting, considering our memory runs at 1.65 volts (as it makes only sense to have this setting).

The above components were used for testing the ASUS Maximus III GENE motherboard. I ran each program a minimum of three times to ensure accurate results and to make stability was present through out testing. This is going to be a “Battle of the Micro’s” type of testing. The only other motherboard I will be comparing the Maximus III GENE against is the ever trusted Gigabyte P55M-UD4 motherboard. The Programs used and their respected testing ways will be listed below. Default testing I did not use the memory XMP profile at all instead I used the default 133 BCLK with a memory divider of 10 while using the default CPU multiplier of 20. Using this setting will ensure that I get a solid base line of performance (absolute minimum). All other settings were set to auto on both motherboards. Only the Maximus III GENE will be overclocked through out testing, as this is just for you to get an idea on how the performance is related once the CPU gets cranked.

Overclocking the Maximus III GENE motherboard was just as easy as previous P55 based motherboards. After doing my initial install of Windows 7 retail, I ran all of my default motherboard benchmarks, I normally overclock the motherboard as soon as it gets put into the chassis and powered up, I started to overclock the motherboard. At first I tried the included software in Windows 7 to see exactly how far it would take the CPU, it would stop at around 3.5ish GHz. Not bad of an overclock for being software based. I then entered BIOS and tried out the CPU upscale, the max the BIOS would go to was 3.6GHz. Again not bad of an overclock if you are new to overclocking and don’t want to mess with the complications of the BIOS. Myself, since I sleep faster then 3.6GHz and I know for a fact the Core i5 750 CPU can do better, I wanted to do some real overclocking. So like any red blooded half crazed lunatic “Mad Scientist” I wanted to see exactly how far I could push the Core i5 750 CPU and how far the Maximus III GENE motherboard will go. So starting off lightly, I set the CPU multiplier to 9, dropped the memory divider to 6 upped the PCH to 1.2 volts manually set the CPU volts to 1.35, memory volts to 1.64.

Then I set the BCLK to 250. Needless to say, that did not go over to well, so I dropped the BCLK to 220, again the motherboard decided it was not going to post. If one is going to overclock lets see exactly how far right out of the gate, if I am going out, I am going to go out in style. I set the BCLK to a reasonable 210 BCLK, the Maximus III GENE motherboard posted right up. Rebooted the computer, re-entered BIOS set the BCLK to 212, again I was greeted with a no post. Dropped the BCLK to 210, then upped the memory divider to 10, CPU multiplier to 20, adjusted voltages accordingly. The Maximus III GENE motherboard posted right up but Windows 7 refused to load (BSOD). After fiddling with a few settings, I came to find out the memory did not peticularly liked being ran at 2100MHz with 10-10-10-30 timings. So dropped the memory divider from 10 to 8 (reducing the memory overall memory frequency), and now I was greeted with a Happy Windows 7 desktop (or was it because I was happy that it loaded?) My CPU is now at a 4.2GHz, ran some quick benchmarks, I had stability (first time I ever been able to use the 20 multiplier on the Core i5 750 CPU with a high BCLK, Nice!)

Overclocked Maximus III GENE motherboard.

Let The Battle Begin

In the blue corner we have the champion, the GIGABYTE P55M-UD4 with 12 phase CPU power distribution weighing in at a pound. And in the red corner the challenger, weighing in around 1 pound as well, with a 10 phase CPU power distribution we have the ASUS Maximus III GENE. The rules are simple, when the bell rings, come out fighting. Ding, Ding, Ding, Ding!!!! Lets get ready to RUMBLE!!!! The things we reviewers do, to keep us entertained.


Well to start things with AutoMKV, between both of these two motherboards. They both converted this short movie almost identical in performance only being seperated by a mere 2 seconds.


Rendering with Blender, again shows us that these two motherboards are about evenly matched. We see a lot more of a gain once the CPU starts to get overclocked.


Excell is just re-interating what we seen with the first two benchmarks. There’s no real concern able difference between the two motherboards tested in terms of performance while in a default state.

Pov ray

Boy I got a feeling this pattern is going to roughly the same through out the rest of our testing session. The only time we seen a significant different in rendering times was during the Camera animation, when the Maximus III GENE lead the P55M-UD4 motherboard by a little more then 2 seconds.

win rar

Now we start to see a small difference between the two motherboards tested. And again the Maximus III GENE takes a win by almost 3 seconds.


Dead even once again.


SiSoft is giving us pretty much the same pattern with most of the other benchmarks. Almost identical in performance.

MultiMedia testing reconfirms the performance of the similar P55 motherboards.

Memory Bandwidth is also Identicle.

Now we see something a bit different. During the latency testing the Maximus III GENE was able to have a slightly lower latency by 4ns when dealing with the memory.


Same performance between the two motherboards.

The GIGABYTE P55M-UD4 does have teeth after all, it was able to out perform the Maximus III GENE in both of the Read and Copy portions of testing.

But again I myself would rather have a lower latency on my memory vs having a higher memory bandwidth. I like things to snap to attention.

Let The Games Begin

3DMark Vantage

Here is that same performance pattern we seen in a lot of benchmarks.


The Maximus III GENE manages to pull a small win when it came to the CPU testing during 3DMark06 testing.

Far Cry 2

Identical performance between the two motherboards.

World In Conflict

World In Conflict again reconfirms the same performance levels during our gaming sequence.

Unigine Heaven

Heaven was the same performance no matter where the CPU was at in frequency.


Through out testing we can see that most P55 motherboards will performa almost identical with one another. With a few exceptions, which we have to ask ourselves, what separates one motherboard from another? The answer is features and capabilities, and or layout. This is where the Maximus III GENE has loads of, features and capabilities (layout is a standard micro ATX). Being able to check voltages on major components on the motherboard, having one of the few P55 based motherboards that uses a rear ward clear CMOS button, being able to access to the on board power/reset buttons, including Creatives very own X-FI sound system, by moving the EPS CPU power button to a spot where accessibility is easier, to finally giving us users the ability to hook up a lap top (or another computer) to diagnose the Maximus III GENE motherboard.

Capabilities fall with in what I personally like to fully and thoroughly test out, is overclocking. Again I need to mention this is so far the only motherboard I been able to sustain a 20 multiplier past a BCLK/FSB (Base Clock, FSB for some you old schoolers) of 200. Another feature that is chipset specific (any P55 based motherboard can do this) that I like personally, is the ability to move from one multi GPU manufacturer to another with out having to buy another specific motherboard to handle either ATI crossfire or Nvidia SLI.

Having a price point on or around the 200 USD mark, makes this a little on the high side, but again looking at the amount of features and shear capabilities you get with this motherboard makes it worth every penny.

Can and will overclock with the best of the motherboards out there

Did I mention that it looks just way to cool.

None that I can see


Summary: ASUS has always shown their dedication to their motherboards, and they continue this dedication with the introduction of the Maximuss III GENE
