Well, my very first overclock every and I must say, it was a breeze. I've been doing a lot of research about OCing ever since I got my 3800+ but never wanted to risk it. But after hearing about people getting the 6600 at 3.4 stock air I was thinking I gotta get in on this.
I wanted to push it to 3ghz initially because when I bought the upgrade it was either the 6600 or an extra $300 for the 6700. The only difference I could see was the 200mhz
I found a guide which had both my mobo and CPU with stock heating to use (Wow huh?) and it had recommended I run my voltage at 1.45V for CPU core. Wow, when I booted I was getting close to 75C in BIOS temps. I did not want to risk a load test/orthos so I reverted to 1.35 which brought it down to 66 idle. Once I reached 3ghz I ran some orthos and my temps would hit 75. Not good. Still too hot. So I went back into the BIOS and adjusted the voltage bit by bit until I was back at my stock setting, which ran 3ghz no problem. I now run at 55C idle and 65-67C which I believe is considered the maximum you want your CPU to run at. Fine with me, I just wanted to hit 3ghz.
So next week I'm going to pick up this little unit here: Zalman CNPS9500
and hopefully I'll be able to push it down to about 40C (Too much to ask? anyone have this cooler?).
It's either that or an external watercooling system, which runs about $350. I don't mind spending the $ on the cooling (I'm a fan of efficiency both temp-wise and speed-wise). Any suggestions?
Also, after I had run a bunch of CPU stress tests I used CPU-z and found out my memory/fsb ratio was 13:15! I managed to get it to 4:5 with a slight overclock. This will be fine won't it? Memtest passed.
Here are my system specs for those interested:
Core 2 Duo E6600 @ 3.0Ghz (333.5mhz x9)
2GB Corsair XMS PC2-6400 Dominator 5-5-5-12 @ 832mhz 2.1V
eVGA 680i SLI NF68
Dual 7900gt SLI (500/750)
Enermax 550W SLI PSU
