Hello. Im trying to get my CPU to overclock properly. I've tried the recommended setting Ive found by searching on the internet and on the site.

IVe tried
FSB - 1333
Ram - 850
Unlinked
VCore - 1.4
Dram - 2.1
HT - 1.4
NB - 1.4
SB - 1.5

Computer boots, but I check in CPU-Z and run benchmarks and there is no difference. I then used ASUS automatic OC feature to OC it 20% to 2.8 and it did work, but Im trying to get to 3.2-3.6. I have a Artic Freezer cooler 7, DDR2 800 Crucial, with a XFX 750Watt http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Any suggestions on settings I could use?

Try setting your RAM clock to 667 MHz for a 1:1 CPU:RAM ratio. Overclocking RAM in a Core2 system just doesn't contribute much to performance and the lower freq will increase stability.

Unless you received a lemon of a CPU chip with a high VID (that's sort of the "stock" voltage for that particular chip), your vcore is too high. You should be able to run at 3.0 GHz with little or no voltage increase.

An ACF7P will be good enough for about 3.2 - 3.3 GHz. For anything higher, you should get better cooling.
