EVGA 750i FTW &Q6600 OCing - Page 2

post #11 of 14
Same setup..... No 3.6 here....

but follow links in my sig..... and as suggested before, stock HSF will not keep it under the intel spec of 71c when OC'd past 3.0.... but you can do what you want..

I have found the GTL ref to be key with any overclock past 3ghz. Without it I can crank my voltages way up to the max and still barely hit 3.2, and higher would be completely impossible. In some cases the GTL ref will allow you to run lower voltages at the same speed, which is nice.

I have not tried to adjust them as of yet... I do notice the second gtl ref voltage always being at 95-110 when set to auto....

Do you have any ref points as to what is too high on those voltages? I cant get stable past 3.4, even with 1.525v.. I was thinking of adjusting them, but dont feel like burning up a chip for a few extra mhz...

Here is a diagram of your chipset:




Try these settings:

CPU Core: 1.45
CPU FSB: 1.4v (This has to be increased as you overclock to match the NB..aka SPP)
Memory: 2.1v (as per the manufacturer's specs)
SPP: 1.40v
MCP: 1.25
SPP<->MCP: This can be left on default. It is the interconnect between the NB and SB.

GTL: Auto (you might have to adjust this to OC the quad core higher)


Set the ram to unlinked and sync'ed
RAM timings: 5-5-5-15
Ram Freq: 800
