Test Setup
The ATI CrossFire Xpress 200 chipset fully supports all AMD Athlon 64 processors in both stock and overclocked conditions.
We tested our 7800GTX video cards using NVIDIA 81.98 WHQL drivers and ATI X1900XT cards with Catalyst 6.2 to provide recent performance results. Resolution in all benchmarks is 1280x1024x32 unless CrossFire is enabled. Resolution in CrossFire benchmarks is 1600x1200x32 with 4XAA and 8xAF where applicable. 3DMark and Aquamark3 benchmarks use a "Standard Score" setup at the 1024x768 video resolution for both CrossFire and non-CrossFire testing. We did not retest the Asus A8R32-MVP for this article due to utilization of the board for other testing at the time of publication.

Status Update - Revised 1.1 BiosAbit provided us a revised 1.1 bios tonight (3-9-06) for additional testing and it will be available on Abit's website shortly. We will update the article after our regression testing is completed.
Hi Gary, it would be great if you could please do that promised follow-up review update for the AT8 especially now the AT8 32X is out. It has beeen a while since the initial review and so things should have settled down now or possibly even a new 'beyond 1.1' beta BIOS has been produced for you?
Please update this review and maybe have a follow up on all the Crossfire boards you have reviewed. There seem to be quite a few owners talking on various forums who bought on the strength of these reviews and are relying on you to get things moving on the manufacturer support front...
I'm personally just waiting to see if the AT8 can be the board it was advertised to be before I take the plunge. Why buy into trouble if you don't need to, I've done the 'early adopter' thing too often already?

We are still seeing issues with Infineon based memory that is set to 2-3-2-5 in the SPD, the board will not boot. If your memory utilizes these IC chips, the only choice you is to install some Samsung TCCD, boot the board, manually change the CAS to 2.5, reboot, shutdown, install the other memory, and boot again. Hopefully, Abit will do another bios spin, otherwise, you are left with this hack.Zoomer - Tuesday, March 21, 2006 - link
Wish you could plug abit's use of the 882D more, it seems to be an excellent realtek chipset. It matches the x-fi in the 3d rightmark tests and is competitive with it even in games. Excellent job!Another thing: Could you guys do some objective listening tests to the audio output? Blind A/B switches between the HDA and onboard audio using good quality speakers and/or headphones will be welcome. :)

Our next step in audio testing, besides subjective remarks, will be doing objective audio tests (besides sampling output from RMAA 5.5) on each new codec implemented on a board. We are still deciding how to do this and my personal preference is to provide a download link to a high quality audio output file from each codec tested. These files would be a standardized clip from a music selection, movie scene, and game sequence. The question is if we will receive permission from the involved parties to allow distribution and obviously what choice of equipment to utilize for the audio capture without distorting the file before playback through the on-board codec or discreet card. Something on the list to do besides new creating new benchmarks also....... :)

Oh sorry, I meant to say subjective blind listening tests. But that might be a good idea too. To avoid licensing issues, you could use public domain music. However, the quality of the client output hardware and the recording method used would taint results.Duplex - Friday, March 24, 2006 - link
A suggestion to develop the audiotest is that you measure 1. the latency from input(ad) to "software" and 2. from input(ad) to "software" to output(da) with or without some well defined effect applied.Realtek: We don't support ASIO & GSIF directly in our driver.
For ASIO, there is an "universal ASIO driver for WDM audio" available on ASIO4ALL. Please refer to http://www.asio4all.com">http://www.asio4all.com. It is free for end-users.

If I am reading it correctly, you are saying the primary slot is the 4th from the cpu, or in the middle of the board and will cover 1 pci slot when used.If that is correct, I suspect this will be a deal breaker for many. It effectively transforms the board to having 1 PCI slot or even none at all, and 2 usable but useless pcie slots, 1 1x and another 8x.
Gary Key - Friday, March 24, 2006 - link
Yes, the primary x16 slot is the lower x16 slot on the board. If you use a X1900XT (dual slot card) as an example you will render the PCI slot next to it useless.

Well, I think it was a bad decision on abit's part. Why leave the top part of the board free while overcrowding the bottom? End users are suffering from these strange board design because of nvidia's SLI now.PS: Yes, I do think SLI is a terribly bad idea.

Excellent review I particularly liked the coverage on the fan control, good work.
