Test Setup
Test conditions were maintained the same, as much as possible, over the platforms tested. For better comparison standard test results (1280x1024) were run with a single NVIDIA 7900GTX on all platforms. A single ATI X1900XTX was also tested at standard resolutions on the Intel 975X boards which support CrossFire. Consider this result a sanity check for single card performance and CrossFire. It should not be directly compared to other test results. Since SLI and CrossFire are not yet interchangeable, 1600x1200 4xAA/8xAF SLI was run on the single NVIDIA-based board with a pair of 7900GTX cards. 1600X1200 4xAA/8xAF CrossFire was run on the Intel 975X boards using a Master+Standard X1900XT CrossFire setup. All results are reported in our charts and color-coded for easier identification of results.
All Core 2 Duo benchmarking used Corsair PC2-8500 (DDR2-1066) 2GB kit at 3-3-3 timings at 2.2V. In recent months the memory market has moved from a 1GB kit to a 2GB kit being the common memory configuration. Our new DDR2 test standard is 2GB.

Im curious, can you go into some detail as to how you determine each memory's stable speeds at the various timings you reported?Did you test any of the value ram up to 1067 or would they not work at all?

Too bad you guys didnt test the asrock conroexfire, its basically similar to the one you tested now but with a 16x pcie slot and only ddr2 support.Gary Key - Wednesday, July 19, 2006 - link
We have more boards coming, the flood gates are getting ready to open from the motherboard suppliers over the course of the next four weeks. Although the press embargo release was moved up to last week, the motherboard suppliers were still targeting 7/27 for hardware releases into the market. We will review and post articles on Conroe capable boards as soon as we receive them. We still have some very good AM2 boards to review also. ;-)

Can you guys run a few benchmarks with DDR1 on this board? It doesn't have to be the full suite, just some to get an idea of DDR1 performance with Conroe. Thanks!Gary Key - Wednesday, July 19, 2006 - link
We are testing another DDR1 board shortly and will have those results up in the near future. Bios version 1.3 on this board improved DDR1 performance and we are expecting another bios spin shortly.

What board is that? Another ASROCK? They have quite a few Conroe compatible ones based on VIA, ATI and the i865G chipsets.
Gary Key - Wednesday, July 19, 2006 - link
Yes, we will be testing the ASRock 775i65G, there might also be a i865 board coming from PC Chips. We should see some additional value based boards in the near future from other suppliers based on the 946PL and SIS662 chipsets.yacoub - Wednesday, July 19, 2006 - link
Lists chipset as: Chipset Intel 975X + ICH8RI thought it was 965?

And on the same page:"Despite the similarity of the ASUS 975X and 965 top boards, a closer look at options does tell you 965 is targeted a bit lower than 965. "

Fixed - as you can imagine given the length, there will probably be a few more typos than normal. Our heads are all spinning a bit after putting this together. ;)
