*Official Retail G0 Q6600 Overclocking Thread*

[chuckbam]

Most q6600's on air seems to need at least above 1.4v to get 3.6. I would try higher volts and if that fails try with higher volts and drop the multiplier to 8and try fsb450 1:1 with memory. I have pll=1.6,fsb=1.3,and NB=1.4 with vcore=1.4125v I don't believe that you want to use BIOS power management if you are overclocking as it will affect the stability.

Dear sesdave,
I will try the the 1:1, I would have the same DDR speed of 900 MHz. 8x 450 ~ 3.6 ~ DDR2 900 MHz. That would work for the DDR. I have tested this memory, maybe a year now, and this is the best I can run 4 sticks with a somewhat acceptable timing.

Under Vista I have the Vista power management configured not to drop the the Vcore when the multiplier drops to 6x.

I will go up a little on the Vcore and see if I can have this overclock with the acceptable thermal result. The CPU should be OK since the Vcore spec is 1.372. I will go up to the Max spec and see it does.

Can you tell me what is the default NB v ? That would give me a reference. I guess I can just look that up. What is PLL?

Like I said, I want 110% stability with this computer. My default OS is Vista 64. Set up for Visual effect. I have a custom aero theme, side bar full of gadgets, TV card running, DreamScene, some FTP folders, and other TSR's. 24/7, not a good test OS. But I did run Prime95 for 8 hours.

Today I will order a OEM Vista Basic and dump the XP as my testing platform.
At this point in time, a fully loaded Vista OS is to fragile for testing. The registry and services is will not withstand BSD, bad shutdowns etc.

Thanks for the TTR's Guide, that is a real nice tool.








PS: I can also experiment with software controlled power management for day to day operation.
