34955 3DMarks in Futuremarks 3DMark 2006

The new Intel Core i7 975 Extreme Edition D0 CPU is an amazing overclocker and will help Intel regain its Overclocking crown

The D0 Revision brings a new level of overclocking for the i7 and makes consistent 5GHz benchmarks a reality for the majority of upcoming D0 i7 chips.

After 200L of LN2 and several bad i7 975 chips I found a decent chip for 3DMark
pulling in 5.1GHz it was not the best chip but good enough to nearly break 35,000 in 3DM06

I am currently working on stable 5.2GHz 06 runs.

Stay tuned I will be adding many more pictures, benchmarks, and a few videos

I have found that all 975 chips i have tested to date are able to clock 5GHz stable with 8 threads, much more above 5ghz requires a "good" chip

when I say bad chip I mean it wont do 5.1GHz runs consistently with all 8 cores loaded :)

Nice runs! Hope you can get 5.2 stable! :)

w3540s and many 920s seems to outclass the 975... although yours is ES so retail silicone should do better

I have a few retail chips too but none of them 965/975 are doing any better :(

GPU Idle temps were 5c and load temps were 15c with the chiller, I don't have the setup insulated yet so i did not go sub zero to avoid condensation.

I have the cards tuned for 1.4v GPU and 1.75v GDDR stable in 3D at 900MHz Core and 1100MHz GDDR
