A look at the new D0 revision of Intel's cheapest desktop "Nehalem".
This is the stock cooler packed with this D0 revision Core i7 920, which runs at 2.66GHz. The stepping is SLBEJ.
The cooler is of a less efficient design than what ships with the top models and it's even worse than the first Core 2 coolers, which had the fins swirled for a better heat dissipation.
In a well ventilated case it hit 80 degrees Celsius, when running at automatic fan speed, which when running prime was at full speed:
HyperThreading is active, so I set the test to run in 8 cores. An aftermarket cooler is definitely recommended, the temperature should be at least around 60 degrees, not 80. Preferrably below 60, especially when overcloking.
I didn't run any overclocking tests but these cores have been tested to reach 4GHz quite easily.
Surprisingly, Turbo Boost still pushes all cores a notch up to 2.8GHz, which as far as I know isn't the case - or it's not supposed to be - with C0 cores and these high temperatures. Is your C0 core also behaving this good?
