It sure has been a busy week for me with R5xx. I got back from Ibiza on monday night and have been running benchmarks all week with Doom 3, Battlefield 2, Half-life 2 and Call of Duty 2 not to forget 3DMark05.
Yesterday I ordered 10 kg of dry ice and did some overclocking testing with Radeon X1800 XT. Thanks to ATI I had appropriate tools and support for that.
I was able to push the GPU easily to 860 MHz until I hit the cap thanks to a programming issue in a current overclocking tool. Unfortunately clock speeds anything higher than 860 MHz froze the system. And I mean while setting the speeds, not running 3DMark. 860 MHz ran perfectly fine without artifacts.
Anyway, I already got a fix to this problem which should solve the 860 MHz limit and I'll be testing that next week. Memory runs with small artifacts at 940 MHz.. it definitely needs some more voltage and 1 GHz shouldn't be a problem at all. My crappy FX-57 was running at 3,6 GHz during the tests. I really need to get a better one!
I started the tests with Sapphire PURE Crossfire motherboard but faced alot problems with our custom made 1320W PSU and dry ice on CPU. Basically the board didn't even boot. I switched to DFI's LanPary nF4-SLI-DR and started testing.
The highest I could get at this point was 12116. More to come next week, stay tuned. Also I'm looking to get my hands on R520 Crossfire. With Radeon X1800 XT and MasterCard I didn't see any improvement in performance
