SLI-Ready Memory Settings in the BIOS

[Kielty]

Can anyone help, i have a ASUS P5N32-E SLI Plus MB and a Core duo 6800 extreme processor with 2gb (2x 1GB) matched DDR2 RAM from Corsair with EPP (CM2X-10248500C5D).

Bios settings are all default at the moment. Processor is running at 2.93Ghz with memory timings at 800mhz 5-5-5-18 1T.

I know nothing about overclocking but want to get the most from my memory. There is a SLI-Ready memory setting in the bios which has the following options 0%cpuoc, 1%cpuoc...5%cpuoc and max cpuoc.

When i put the setting to 0%cpuoc the memory timings run at 1027mhz 5-5-5-15 2T which is what i wanted.

My question revolves around what are the settings for and what do they do? I presume the other settings are used to overclock the processor? why then if i chose any of the other settings the memory still runs at the new speed and there is no difference to the speed of the processor 2.93 ghz)

Can anyone explain/help?

Whats the best way to achieve a processor oc? Leave the sli-ready settings at 0%cpuoc and change the multiplier? select AIoverclock in the bios and raise that setting?

Not sure why that is, but you should manually overclock, this will get the most out of all your components.

Go into you RAM settings and set the timings to the stock speed (not sure, 5-5-5-15?) and lower the Mhz to the minimum possible (probably about 557mhz). Now start to increase your FSB settings by about 10mhz each time, exiting your BIOS and checking that your computer boots up ok. Get to a nice level (around when your RAM hits its highest stock speed, maybe just a bit lower) and run CPU Burn-in for 15 minutes. If your computer stays alive during this test, all is well and you should be able to crank up the FSB a little bit more, again, run CPU Burn-in. Do this until you are too scared to go further.

Thanks for the info. I just increased the cpu multiplier from 11 to 12. Now my system is running at the 5-5-5-15-2T 1027mhz memory timings and cpu is running at 3.21ghz.

Everything seems stable. Is this a reasonable overclock for a 6800 extreme processor air cooled?

3.2ghz seems to be what a lot of c2d chips will do. Did it need any extra voltage?

[Kielty]

no none at all, just an alteration to the multilpier.

What did you set the vcore to?

[Kielty]

I didn't set anything. The BIOS took care of the voltage. All voltages in the BIOS are set to 'Auto'.

On looking at the voltage monitor - vcore voltage is 1.29v.

[Clunk]

If it is indeed 1.29v, its a nice overclock for the given voltage

To be honest, anything around 3ghz for a dual core proccy is gunna be awesome. That should run anything that doesn't support dual core at a reasonable level.

Sounds good, and you've probably still got some headroom for more.

I'm running Vista and the windows experience index for the processor is 5.7.

Seems ok to me...

As long as its stable, you'll be fine for quite a while.
