Hello all.
Been lurking for a long while but now have a problem which has me stumped.
I bought a Q6600 (G0) off the bay. It came lapped, and had was described as being OC'd to 3GHz on water, so thought a modest overclock.
It was a direct replacement for an E6600, which id previously OCd to 3.3 Ghz on stock cooler with no problems (good case with cooling, Antec P180). But i cant get about about 2.7Ghz without BSODs, hanging, restarts.
Ive read a number of overclocking guides (including the sticky here) and have only gone up in small increments. It seems ok at 2.5/2.6 (passes P95 small FFT), but at 2.7 or higher it either hangs on loading (W7 64), BSODs or restarts.
I upgraded the cooler to a reasonable Gigabyte G-power 2. Thought must be better than the stock intel. Temps at 2.5Ghz are only 45-48 full load, 32-35 idling.
Ive tried upping both the memory voltage (to 2.1, in increments - stock is 1.8) and the vcore (from 1.25 up to 1.4, again in increments). Nothing seems to help. Been trying this for nearly a week now. Memory set at standard timings (5-5-5-18).
Prime 95 blend test even fails on stock/auto settings, although the small fft passes for an hour. Thought might be memory so Ive ran memtest overnight and no errors. The memory was bought on two occasions, although is identical - bought another 2x 1gb at same time as cpu. I also tested the exisitng 2gb with memtest prior to installing second.
Im stumped. And frustrated. Does anyone have any suggestions? Is it just a duff chip? May be able to to a refund if so.
My specs;
Q6600 G0 stepping.
Gigabyte Gpower2 CPU Cooler.
4x1gb Corsair TWIN2X2048-6400 5-5-5-18
Abit Ab9 Pro Motherboard
Coolermaster 500W PSU.
Antec P180 Case.
Nvidia 9400 GT GFX card (1gb)
60gb OCZ Vertex2 SSD system drive
2x320gb and 1x1TB storage drives.
Computer is used for music (Cubase/Ableton) and not games, which take full advantage of additional cores.
Many thanks, regards
Ben
