Massman Posted January 22, 2011 Share Posted January 22, 2011 Not sure if anyone else noticed it, but there's a big difference between the different mainboard/bios combinations for 3DMark01 performance. So far I've only had luck with the Gigabyte UD4 to get good 01 runs. Any other board has performance ~ 3k to even 8k lower. Here's the data: HD 4890: CPU MHz vs CH: - 5288 - 535 - P67A-UD4 (F6x) - 5545 - 505 - P8P67 Deluxe (1053) - 5300 - 549.6 - Maximus IV extreme (0681) - 5400 - 482 - P67A-GD65 (1.8B6) - 5412 - 511.4 - Maximus IV Extreme (0681) - 5200 - 465.3 - P8P67 Pro - 4890 - 513 - P67A-UD4 (F4) - 5300 - 480 - P67A-GD55 (1.8B5) - 5366 - 525.8 - P67A-UD4 (F7b) As far as my own testing goes I only had good runs with the UD4 (as mentioned before). M4E and GD65 gave me ~ 490FPS at 5.4GHz (should be 550!). Only hole in the gigabyte theory is U22's run with the M4E + 0681 bios. At 5300 he's at 550, my runs were at 515FPS. You will see the same with other cards, by the way. Check the top results of the GTX 580, for instance: - 409FPS @ 5500MHz (GBT UD7) - 395FPS @ 5620MHz (ASUS board) Only problematic run (maybe not right lod?): 395FPS @ 5500MHz with UD4, but still ... same performance level as the asus boards but with lower MHz. I've tried to come up with a solution when running the M4E, but nothing helped. Tried changing mem dividers, different OS, different timings, different pci-e lanes etc ... no way to reach the high performance. When switching from the 0065 to the 0681 bios on the M4E, I went from 490FPS CH to 515FPS ... nothing changed frequency wise. What are your thoughts?
