We have rarely tested a board with such incredible stability in overclocking as this Sapphire ATI. It was not always easy to reach our desired overclock with all of the exceptional range of options available in BIOS, but once we reached the overclock, it was extremely stable. We did notice that the Sapphire ATI responds best to gradual increases in overclocking - it does not like, for example, to be set directly to 245 clock frequency. It will reach higher overclocks if the Clock frequency is increased gradually instead of in one fell swoop.
The Sapphire ATI reached a new record with our standard 4000+ Clawhammer. The highest previous overclock at stock multiplier was 242, but the Grouper went on to a stable 245. This would be quite an accomplishment for any board, but it is remarkable for a first production board. The 302 Maximum bus frequency was also a great performance. ATI clearly set out to build an enthusiast board for Sapphire that other manufacturers could copy down to the smallest detail. Sapphire was smart enough to recognize a good thing when they saw it and they have faithfully reproduced the original Reference board. Our advice to most manufacturers developing ATI Radeon Xpress 200 designs would be to copy the Reference Design. Unless you are certain that you can extract even more performance from this chipset, it is best to copy the top-performing Xpress 200 Reference boards - whether single-GPU or Crossfire Dual-GPU.
At settings of 2T, we could reach even higher to a frequency of 320. There is a lot of discussion on the web these days, claiming that you can minimize the impact of the 2T setting with certain options on Revision E AMD processors. We did not verify this claim in our tests with an earlier standard Clawhammer processor, but we can tell you that all the talk about options for improving 2T performance modes are in the memory timings section. It is little touches like this that tell us that enthusiasts in ATI or Sapphire or outside the company have had a big hand in the design of the Radeon Xpress 200 family of chipsets.

Guess you missed where i said "(with the exception of MSI)". Learn to read mate before you go posting.RobFDB - Friday, July 29, 2005 - link
ATI and Sapphire should be congratulated for bringing the AC880 to AMD users. We had it good with Soundstorm but since then onboard audio as gone back several steps (with the exception of MSI). Its good that AMD users are being given the option to have quality onboard audio.bob661 - Friday, July 29, 2005 - link
This what impresses me the most about these boards is this codec support. I still won't buy an ATI chipset until the third or fourth version comes out (you guys can test it for me) but impressive features and performance nonetheless.jab98 - Friday, July 29, 2005 - link

"[AMD] Enthusiast" is written with a capital E in the article, and it should not be, since it's not a proper noun. Please fix this error, because it looks grossly unprofessional to anyone with a reasonable command of the written word.RobFDB - Friday, July 29, 2005 - link
Really though, get over it. It doesnt matter in the slightest if we're being honest here. Anyway back to more important matters.I'm really happy that ATI have managed to bring a top performing board aimed at enthusiasts to market. I was also extremely impressed to see Sapphire implement 4v for the RAM. One issue that i'd like to see investigated is wether the cold boot issue that affects DFI NF4 boards using OCZ VX mem @ high voltages affects the Sapphire board too. Aside from that this is a very impressive showing from ATI. One last thing. I have a x850XT PE and i'm not sure if that can be used as a slave card when ATI bring out the R520. If so that would make a very attractive upgrade.

The X850XT PE works fine as a slave with the X850 Master Card. In demos at Computex, ATI was showing an X850 Master with an X850XT PE slave.Jojo7 - Friday, July 29, 2005 - link
This isn't exactly true. Ati distributed a special driver that SIMULATED crossfire. The actual cards were really just 2 identical x850xtpe's. Though, one probably had an altered bios to simulate a master card.Read it for yourself: http://anandtech.com/weblog/default.aspx?bid=231">http://anandtech.com/weblog/default.aspx?bid=231

Did I miss the mention in the article? Is this an ATX or an mATX board. I'm guessing the former, but it wouldn't be out of place to list the fact along side the rest.erwos - Friday, July 29, 2005 - link
It's ATX. If it has more than four slots, it's too big to fit the mATX standard.
