Introduction

IntroductionIntel has a lot to be proud of when looking back over the last two years. Core 2 has paid dividends for the company and finally they no longer have to put spin on lousy products like they were forced to do with Netburst at the end of its life. What it came down to was that Intel simply pushed Netburst CPUs too far. The lineup should have ended at Prescott. Netburst is now forgotten, and Intel are wholeheartedly forgiven with the Core architecture; it not only manages to keep the processor speed at around the 3GHz mark (which is roughly where the Netburst CPU left off), it keeps things moving forward with architectural advancements that further improve on the already excellent multimedia decoding and encoding performance the Netburst processors were reknowned for; not to mention improving gaming performance to the point that the Jolly Green Giant simply can't match. Not only has the processor improved, so has the platform. Intel's use of the aging 975X chipset as its enthusiast level chipset was beginning to wear thin. It lacked DDR2-800 memory support and its Crossfire support with only twin x8 slots was starting to really pull it down. Even the P965 was able to kick it from the top rung thanks to its DDR2-800 memory capabilities and Crossfire support; while not the perfect match, it was a more desirable chipset. P35 managed to do a good job in the interim whilst waiting for a high performance chipset. P35's dual memory support made it an ideal stop gap chipset for the enthusiast level.X38 is now here, and it's still a mixed bag in regards to how it performs. So far there aren't really any performance breaking features of the chipset, it's basically a P35 but with better Crossfire support and a few novelties such as XMP memory profiles. Today we are testing out the ASUS Maximus Extreme board which is designed to be the most impressive board ASUS has ever put out to market.

The Box and What's Inside

Package and Contents
Starting off as normal we come to the package and what's lurking inside. One thing is for certain, there is no shortage of bits and pieces in this box! The box itself is a plain affair on the front; this is because it's part of the R.O.G. or Republic of Gamers series of boards. Its basic design mimics the entire Intel range of ROG boards, only the name on the front is different whilst the colour scheme is identical with the same printing; very little at all on the front.
The back of the box contains a full spec sheet on the board's features, the exact same one that is on the website so that you get a full rundown of the slots, chipset and feature support. There aren't any full colour photos of the board but there are a few of the extra features the board comes with such as the audio module.
The box comes with a front open flip cover that gives you a better view of the ASUS Fusion block system as well as the audio board. There are no colour photos of the board here either, which is a bit of a disappointment. It would be nice to see in full view what you're buying before you actually take it home.
Moving along, ASUS has a light bundle in terms of software. Two CD's are provided; one contains all of the Windows XP, XP64 and Vista drivers you're going to need. If you are a Linux user you're going to have to search for drivers, but really if you're going to get a board this flash, it's for a gaming rig that 99% of the time will be running a Microsoft OS as the majority of games out there don't have Linux support. The extra CD is a full retail copy of the blockbuster FPS game, Stalker.The user manual is extremely thick and contains oodles of information on the board, software, driver installation and BIOS setup. ASUS always goes full throttle on the user manual; leaving nothing unmentioned seems to be their way of thinking.
Moving along to the data cables, ASUS doesn't skimp here either. Out of the six internal SATA ports that the board gives you, there are six SATA data cables so you can populate this board with six drives straight out of the box. The ribbon cables supplied are a single FDD cable that supports one drive and an IDE cable with two-drive support; gone are the days of two IDE ports on the board, but SATA really has this market now and there is no need for IDE anymore apart from optical drives.
There is unfortunately one area where ASUS does skimp out, and that's power converters. Only one molex power splitter with two SATA power ports are included. If you want to use six SATA drives on the board, you had better hope your PSU has at least four native SATA power ports or you're back to the shop to buy more.

Package and Contents - Continued
If you're the type of person who likes to keep their eye on things in your PC, especially in regards to how hot things are getting, ASUS is on your side. Included are three extra temperature probes that plug into the motherboard below the expansion slots. These are user locatable so you can attach them to anything you desire. You could put one on the HDD, one on the northbridge heatsink and one on the graphics heatsink; or if you're going to run Crossfire you can have one on each card and one on something else of your choice.
The LCD poster panel is a new little device that ASUS has come out with. This plugs into a port on the motherboard which you then route the cable through a slot in the rear I/O shield on the back. This can then sit on your desk or at the top of the case. It reports the post codes of the board and lets you know just what's happening with your system; a very novel approach.
The Fusion block on the northbridge is designed for users with water cooling systems. Rather than making you go out and buy extra connectors, ASUS gives you reducers and clamps so all you need to do is connect this baby into your existing water cooling system and you're off.
If you're going the water cooling route, chances are unless you're using the Gigabyte 3D Galaxy II, you won't have any fans to keep the Mosfet heatpipe cool. In this event a special blower fan is included which you place on top to run cool air over the Mosfets; a very interesting design.
Lastly on the lengthy list of inclusions is the SupremeFX II audio module. While it may sound flash, the audio module is simply a daughter board with the HD audio codec on it. It's the same onboard audio that all Intel ICH9R boards are equipped with, just on a separate card. This is supposed to result in less noise on the audio channel, but I consider it more of a convenience as you don't have to plug the card in if you are using a separate audio card like an Audigy or X-Fi.Phew, I think I managed to get it all in there. Now let's move onto the board itself.

The Motherboard

The Board
Whoa, what a sight! ASUS has gone with the traditional ROG black/dark brown PCB colour scheme and blue and white expansion slots. It's a monster of a board coming in at 30x24cm, and it's a heavy monster with all the heatpipes and heatsinks on it too. You're going to need a forklift to move it! Okay, I'm going overboard. It's hard to find too many faults on the board. The 24-pin power connector, FDD and IDE are located all behind the four DDR3 memory slots with the IDE port being placed on the very edge and aligned 90 degrees. The extra 4/8 pin CPU power combo port is squeezed between the heatpipe assembly and the rear I/O ports at the top left of the board, this keeping it as far away from the CPU area as possible; though if you have to unplug this cable inside the case to replace a PSU, it's a bit cramped here to get to the locking latch.The SATA ports that the board is equipped with are located below the IDE port and are stacked two atop each other and also rotated 90 degrees to the board. This keeps the cables from sticking up and preventing large graphics cards being installed. GIGABYTE's P965 had this problem where you couldn't get a second graphics card to install if you had all the SATA ports populated.
Moving to the CPU area and this is where things turn around a bit. Because of the Fusion block heatsink, heatpipe and cooling fins around the voltage regulators, the CPU area is a little cramped; it doesn't stop the installation of large heatsinks or water blocks though, but the nature of the LGA775 locking pins means you have to push them down hard, and with little space to do it in you're really going to struggle. The best idea is to do it outside the case as when it's installed you're going to be in a mission impossible stage. The CPU is powered by an 8-phase voltage system with all solid capacitors and voltage regulators. Reliability and overclockability go a long way with these types of components.
The rear I/O ports on the back are proprietary to ASUS and have changed again, so if you are an ASUS upgrader (that being you're moving from an older ASUS board to this one), you're going to need to install the new rear I/O shield. On the back you have a single PS/2 port for a keyboard, but there are no mouse PS/2 ports which is kind of silly. If you're going to have one PS/2 port there, might as well put the other in too. Two eSATA ports are located on the back and are powered off the JMicron PCI Express controller chip which gives the board its single IDE channel. The most notable feature on the back is a Clear CMOS button that allows you to reset the CMOS without having to open the case.
Lastly on our list are the expansion slots the board supports. Based on the X38 chipset we now get full speed Crossfire support. Intel's X38 chipset supports 32 PCI Express lanes off the northbridge which are PCI Express 2.0 compliant; so if you are lucky enough to have a PCI Express 2.0 card (or two) you can take full advantage of it on this board. The slots are backwards compatible with the PCI Express 1.0a protocol so you can run your current graphics card(s) in this board no worries. There are a total of three PCI Express x16 slots on the board; two blue and one white. The two blue ones are routed off the X38 northbridge and run at full speed. If you decide to use the last one, you have to enable this option in the BIOS and this is when the magic happens. ASUS has included the IDT PCI Express router chip that will split the last PCI Express x16 slot with the x16 slot above; this making up two PCI Express x8 slots if you desire to use an extra PCI Express graphics card and enable the feature in the BIOS. This chip is the same one used on the Blitz Formula and Extreme boards which give the Crosslinx support. Finishing off the expansion slots you have a single white PCI Express x1 slot and two PCI slots. The last small slot sitting at the top is the audio module card slot; it is not a PCI Express slot but simply a routed slot from the southbridge's AC'97 audio system.The additional extras that populate the board are two PCI Express Marvell ethernet controllers, a JMicron PCI Express SATA/PATA controller chip, a Texas Instruments PCI based Firewire chip and the IDT PCI Express router.

BIOS and Overclocking

BIOS
ASUS' BIOS design has not changed. Using the Award Modular BIOS in tab menu form as we like to call it, it resembles the same BIOS look as the Intel desktop boards. Under the Advanced tab you get your overclocking options under the Jumperfree menu which is the same setup as the older boards used.

Our overclocking result was quite good. With all the settings we had on tap, we managed to get our system to a stable 527MHz FSB with a 6x multiplier; a very good result for our first X38 test board. While it hasn't managed to hit over the 550MHz mark like some of the better P35 boards (even the ASUS P35 boards are able to do this), more mature BIOS updates will need to come out as Intel is still tweaking this chipset itself. Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the maximum limit and find the highest possible FSB as this could take days of testing. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
