Asus P5WD2-E Premium: Intel 975X for the Enthusiast

Disk Controller Performance
With the variety of disk drive benchmarks available, we needed a means of comparing the true performance of the wide selection of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs. the World. The iPeak test was designed to measure "pure" hard disk performance, and in this case, we kept the hard drive as consistent as possible while varying the hard drive controller. The idea is to measure the performance of a hard drive controller with a consistent hard drive.
We played back Anand's raw files that recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's iPEAK utility was then used to play back the trace file of all IO operations that took place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance differences to the controllers that we were testing, we used the Maxtor MaXLine III 7L300S0 300GB 7200 RPM SATA drive in all tests . The drive was formatted before each test run and a composite average of 5 tests on each controller interface was tabulated in order to ensure consistency in the benchmark.
iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation. In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned as it is just the number of IO operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.

Just bought this and I am having a problem even getting this to post. Fans boot and HD starts to boot. No video image, monitor resets and then blanks.I stripped out unnecesary components- still no joy.
I have an Thermaltake XaserIII 480 with adapter and EZ 4 plug molex connected.
SATA 1 Port using WD 80 gig HD
Pentium D 805 w/ stock heatsink.
Inno3d 6200 TC video in 1st PCI 16 slot.
2X1 Gig PNY memory in Black series of slots.
I will be trying to use only one stock of memory, and then will be taking MB out of case and trying to boot on non-conducitve surface. Anyone else got advice?

I've had it now for almost a week and have started noticing problems. Many forums are now littered with complaints, mainly aimed at the Marvell issue.I mistakenly had set up my system the first time with the Intel chipset and using "Standard IDE"... system worked fine other than the issue with the Marvell. Benchmarks ran fine and 3DMark06 looked great.
I then reinstalled the OS, this time doing the PITA F6 procedure and set up the drives on the Intel controller using RAID (but didn't actually set up a RAID, simply wanted the AHCI with the ability to in the future set up RAID).
This morning I tried to run the 3DMark06 benchmark and while it ran to completion, the graphics screen seemed all corrupted throughout...I'm thinking power problem but it didn't have this issue last go around. Can setting up the drives differently have caused this from a power perspective or is this just one of the possibly many things wrong with this board?
I am wondering if I should RMA it back to zipzoom and get the Intel board, which has always been my choice, except this time the extra SATAII ports provided by the Marvell persuaded me to give ASUS a shot...ironic, isn't it!
In your opinion, based on what you know, will the issues with this board be resolved by BIOS/driver updates? It is a PITA to take my rig apart to swap out the motherboard but I will bite the bullet and get the Intel 975X board if this board can't be fixed via BIOS/driver updates.

I've had this m/b for a few week's and I have to say that it has many bug's in it. As far as i know, no one has gotten the marvell sata driver's to work and on the intel side people have gotten many mixed result's. I gave up trying to make a raid on this board. Asus support is nowere to be found, I think if any one want's to rate it then yhey should test all of the components of the boardGary Key - Saturday, February 11, 2006 - link
Email me and I will provide you with an updated bios that solves the USB issue and voltage spikes. I still have not had an issue with the Marvell RAID setup and two Raptors.

Gary,Could you please e-mail me the updated bios? email: qommonsense@gmail.com. Thanks.
Richard.

As far as the motherboard goes, it looks pretty good. NB/SB are passively cooled, the layout is good and the MOSFETs are heatsinked (I've heard of problems with the voltage regulators on cheaper intel boards failing, often because they got too hot). I like how Anandtech's motherboard articles are very critical and mention things that other sites seem to glaze over, such as if the board's voltage regulator is three, four or eight phase.should read "processor's"

It is corrected. I had it marked on the final edit but missed it before publication, excuse the Homer moment please. :-) It is a good board but we felt like Asus did not go all the way on it and should have considering the price point. Although the board is not in retail yet we were somewhat disappointed with the bios also. Asus is working on a new release at this time and we hope to be able to test it in the next roundup.

HiWhen may we expect the ANANDTECH 975x shootout ?

We should be finished in about three weeks. We have two additional boards in house and another two on their way. We will also have an overclocking shoot out with the Presler and Cedar Mill chips.

HiAny news about the 975x shootout ?
