Overclocking on the Asus Maximus

simmonz · 18 Feb 2008 at 12:06

Hi all,

I just had a quick nosey around the Bios there, and while the ram was pretty straight forward to set speed rates for. I have 8GB DDR2 667 MHz at the moment...so I upped it to 800MHz just for a little tester.

Aside from the memory, I was looking for the CPU speed, but cant see anywhere in there that allows me to set a voltage or speed for the cpu.

While I'm new to Overclocking..I wouldnt mind increating the Core 2 duo "conroe" 3.0GHz i have..and say push it up a bit..same applies with the GPU.

Any advise available on this particular board? I was told the bundled software that allows you to overclock...is a bit sketchy

Go into the bios, Extreme Tweaker and look for AI Overclock tuner and set to manual. You will then have access to your FSB and lower down in the list (much lower down), access to cpu voltage etc

I would leave cpu voltage on auto until either your overclock fails a stability test (Prime 95) or fails to boot. Nudge up the fsb in 25 mhz steps. This board, depending on which bios revision you have, is good for a FSB in excess of 500 but you would need to lower the CPU ratio to apply that. Best bet initially is to stick with standard CPU ratio (10 I assume for your chip?) and just bump up the FSB until it fails to POST. When it fails, go back into the bios and add a little cpu voltage until you can get back into Windows and pass a stability test.

Enjoy.

I remember looking at that briefly. I've set my ram to DDR 2 800 in the auto settings..not sure how to manually configure this..but i'll keep upping it etc

Head for DRAM frequency and preferrably set at either 667mhz or next lowest setting as when you increase the FSB the ram speed (frequency) will increase also. You should check out the timings and voltage required for your ram and set the ram voltage manually (under DRAM VOLTAGE) to the manufacturers recommended voltage and try either try setting ram timings at their rated spec, ie 4,4,4,12 etc or loosen the timings slightly to something like 5,5,5,15 as this will put less strain on the ram and reduce the likelihood of the ram becoming a limiting factor. Then head to the FSB and increase gradually as previously mentioned. Don't get too aggressive with the bumps in speed, keeping to increases of 25 mhz (maximum) per time and after each time, booting into Windows and running a stress test for about 15 mins. As your FSB increases stress test for a little longer.

You should also DISABLE C1E and Intel Speedstep (found under the advanced tab under CPU configuration). Also disable Spread spectrum and PCI-E Spread Spectrum under the Extreme Tweaker tab.

That should be more than good enough to give you a nice increase in speed.

Good luck
