DFI LANParty UT RDX200: ATI’s Crossfire AMD for the Bleeding Edge

Basic Features: DFI LANParty UT RDX200
The DFI nForce4 Ultra and SLI boards quickly developed a reputation for offering the enthusiast every imaginable BIOS option. The DFI RDX200 goes even further.
Memory voltage extends to 4.03V without the need to resort to jumpers to add voltage from the 5v line. Memory controls are even more extensive than those that DFI provides on the nForce4. When we reviewed the ATI Crossfire Reference Board, we commented that ATI has worked with some leading enthusiasts in refining the Crossfire AMD. DFI has built on the depth and breath of the huge array of options available on that board.
A good example of this is the options available for memory speeds at stock speeds. Not only can you choose 200, 266, 333 and 400, but you can choose and fine tune with in-between speeds like 240, 280, and 300. Beyond the standard 400, you can choose 433, 466, and 500. This allows those who would never think of overclocking their CPU the ability to run their memory at DDR500 for example. For those who do overclock, this increases the ability to fine-tune the CPU and memory for the absolute best performance.
Oskar Wu, the Engineer behind DFI's legendary nForce4 series, is also the designer of this DFI RDX200. With so much already available in ATI's Reference design, Oskar concentrated on adding the "impossible" option of running 4DS DIMMs at 1T Command Rate and a working CAS 1.5 option in BIOS.

Board just came in stock at newegg for $209+5 shipping.Also what psu was used in this test. I read somewhere that the board needs an 8pin connection from the psu and that very few psu's have this right now.
I can't seem to find where I read this at atm.

We use the OCZ 520W as a standard bench PSU. It has both 4 and 8-pin 12V connectors. 8-pin slots will also work with 4-pin 12V plugs.Zoomer - Wednesday, October 19, 2005 - link
Will there be a value ATi board?I don't forsee myself getting a xfire solution, ever.

Guess who is getting one this week? hiihihihiihih x850?danidentity - Wednesday, October 19, 2005 - link
You make no comment on the stability of this board, how is it?cryptonomicon - Wednesday, October 19, 2005 - link
Sorry, but I can't help but ask why the gaming performance graphs were not all done on the same graphics card. Initially I thought WOW THIS NEW ATI CHIPSET IS MAD FAST but then I see it was using the 7800 gtx while all the other boards got 6800 ultras... WTF?What the heck is going on? Was the scientific method forgotten or something? This is a let down.

I'm always amazed in reading AT Comments that those who complain loudest are the ones who don't even bother to READ the review. I may not always agree with Wesley's approach on a review, but I know his results are always documented clearly in the review, logical, and repeatable. In fact he is the reviewer at AT who is most careful to always document the components he tested with and the setups. Derek and Anand often leave you guessing how they tested and you have to ask to figure it out.If you had bothered to read the test setup you would have seen that the red bars are tests with the 6800 Ultra - the same used in every other compared board. The 7800GTX and Crossfire were BONUS results - for those who would be screaming "Why have you tested with the obsolete 6800 Ultra instead of the 7800GTX".
Please READ before you scream so your rants aren't a total waste of time.

Sorry to have to point this out, but assembling and testing a motherboard can take several days. The 7800GTX scores were there for reference, but 6800 Ultra was used as well (the red bar) to make scores comparable. It's not practical to go back and retest seven (or more) motherboards every time a new article needs to be published. If we don't include something like the 7800GTX, people wonder how that affects performance. Just look at the red bars for motherboard comparisons and the gold bar to see what a $500 (instead of $350) GPU will do. :)cryptonomicon - Wednesday, October 19, 2005 - link
nevermind, wesley made no error, just me :D the board using the 6800u in red is the direct comparison (which it said in the article, albeit not on the gaming performance page). must have been too late at night or i was just too dumb to see it! excellent article as always.cryptonomicon - Wednesday, October 19, 2005 - link
hats off to DFI, this board is wicked fast. i am curious though as to how it will sell given the high price.
