4000+ on a8n-sli premium: how do you overclock it?

[oajr]

hello friends. not looking to oc to an extreme, would like to get a small improvement if possible. antec 1000amg and stock air cooling, psu shown below. i went into the bios and the cpu speed was "greyed out", i'm hoping that doesn't mean that i can't do what i'm looking to do. i stumbled across another area in the bios setup which showed some sort of multiplier choice. anyhow, i'm simply looking for some direction, i read a magnificent write=up (sticky) by Zebo, however i'm still a bit lost.

any help would be appreciated.

thanks in advance

OK, I'll give you a quick intro to overclocking A64s, since you dont know the basics. After this you should be able to understand Zebo's guide better:

There are four things you have to work with when overclocking:

The HTT/cpu clock, which defaults at 200

The Hypertransport Multiplier, which defaults at 5 <- This is sometimes labeled Hypertransport Frequency. If so then it will be in steps of 200 (or 100, in some rare instances). Simply divide this number by 200 and that will give you your multiplier. Some motherboards support half-multipliers as well.

Your DRAM Frequency setting. Setting this to AUTO will probably let your bios auto-adjust the divider in order to keep your ram running at 200MHz (DDR400).

CPU voltage. Also called VID and Core Voltage. Increasing this can help you achieve higher overclocks and better stability, to some degree. You cant just keep pumping voltage into the CPU indefinitely, though. I wouldnt recommend that you go over 1.5v unless you KNOW WHAT YOU'RE DOING. This is the easiest way to kill a CPU.

Like Zebo's guide says, you have to keep your REAL Hypertransport frequency (HTT x HT multiplier) under 1000MHz, or you'll experience isntability.

thank you, Furen. i looked through the bios (phoenix) again and i did find the "hypertransport frequency" and it was set at auto, my choices were 1x,2x,3x,4x,5x...also, my cpu "vcore" voltage is regulated at 1.39v or you can choose "ignore" but that's it.

thoughts?
