I have:
Q6600 (G0)
800MHz DDR2 RAM (6-5-5-9 at 800MHz)
8800 GT
Antec 900 case
Standard Intel heatsink (was going to use ACFP7, but out of stock)
Asus P5KC (P35 chipset, supports 45nm procs and DDR3 RAM)
So my temperatures were low and I decided to do a little overclocking. After reading on the Internet how various overclockers could achieve 3.2GHz+ on this kind of system, I was pretty confident. Bought a magazine (www.custompc.co.uk) with a guide in. First time overclocking.
I upped my FSB to 300MHz (from 266) and locked the PCIe bus at 100MHz and changed the RAM frequency to 600MHz effective. It crashes (which is normal). What is shocking is that I had to go up to about 1.4V to get it stable again, and even that was only good for two hours of Orthos and 60 celcius.
Using CPU-Z, it appears my Core voltage is well under 1.25V, even though the BIOS setting (and my temperatures) reflect much more than that. I can't even get to 3GHz without going over a 1.5V setting and about 75 degrees.
After seeing reports of 3.2GHz on 1.325V, I can believe that, if my vCore would actually go that high, instead of being Vdrooped by more than 0.2V. Have I just got this wrong in what I am expecting from my system, or is there some setting that will solve my issues?
Been getting some nasty artifacts when gaming on my measly unstable 2.88GHz (more stable than the 3GHz at least) so I have turned it off for now.
