ASUS P6X58D Premium
Core i7 950
Corsair Dominator GT 6 Gb CMG6GX3M3A1600C7
Sapphire Radeon 5870 Vapor-x



My best O.C. so far on this board.
4.6 GHz
BCLK @ 200 MHz
CPU multiplier @ 23
DRAM multiplier @ 8 for 1600 MHz
GPU @ 890 MHz memory @ 1280



With BCLK @ 205 CPU @ 23 @ 4.7 GHz overclock is not stable for long, It locks up windows after a few seconds. With BCLK @ 200 CPU @ 24 @ 4.8 GHz it keeps rebooting over and over. RAM seems to be stable up to around 1700 MHz or so, With Memtest86+. Any more overclocking on the video card locks up after about 10 min. I don't know if its just the video card, Or a combination of the CPU overclock and the GPU.
Temps are a bit high, but it is 4.6 GHz after all, And i'm benchmarking sooooo.... acceptable to me Idle temps around 46.
I'd like to run 3d Mark Vantage, but i've already used my freebie :/
More benchmarks to come! Except for Unigine Heaven, because the Catalyst 9.12 drivers seem to have broken Direct X 11 tessellation, Though i may go back to 9.11 just to run this bench.
Any requests?

What are your CPU temps running OCCT linpack tests (ran for at least 4hrs) or IBT (10 passes)? I find it incredible your max CPU temp is only 75C at 1.416v with the H50.

Results after 1m 30s, 85 C, I shut it down after this, But it did seem to be leveling off. Prime 95 is just as bad. So the H50 isnt all that and a bag of chips, Just adequate, And it holds the temps off long enough for most benchmarks to finish.



BTW i'm just looking for the highest bootable O.C. i was'nt going for stable temps just yet. Im ordering 2 more Noctua fans for the radiator for a push pull config. Should only make a 2 to 3 degree difference, But sometimes thats enough.

Crysis @ 1920 x 1080 very high settings 16Q Antialiasing. Same CPU, and GPU clocks as 1st post.

Unfortunately if you're hitting 85C already, even with the push-pull fans I don't think you'll be able to determine whether or not 4.6ghz is stable because your temps will get even higher. I had 4ghz stable on my i7 at 1.29v but it failed the OCCT linpack test after 7hrs (I test for 8hrs min). At 1.3v I'm stable though.
