Overclocking help.

i have Gigabyte GA G31M-ES2l mobo.
intel c2d E7500 proccy @2.93 ghz.
2gb 800 mhz DDR2 ram.
but i cannot overclock it beyond that.i have read that it is possible to overclock using this mobo.

here is the bios message or settings i get.

cpu clock ratio [11x]
XFine cpu clock ratio +0.0
Cpu frequency 2,93ghz (266x11)
cpu host clock control [disabled]
Xcpu host frequency (mhz) 266
PCI express frequency (mhz) [auto]
Performance enhance [standard]
System memory multiplier(spd)[auto]


system volt control [manual]
DDR2 overvolt control [normal]
FSB overvoltcontrol [normal]
Cpu pvervolt control [normal]
Normal cpu vcore 1.28750v

i cant do the clock ratio beyond 11x. is there anyway to do it.
the place where X is shown they are disabled.

Please help.

  1. First of all, the E7500, like most Intel chips, has a locked internal multiplier. That's why everything past X11 does not work.

    Second, the G31/G41 chipset is an economy, entry level chipset. Unless you get really lucky, you will not be able to push the FSB freq past about 360 MHz. I have a G'byte G41 board. FSB freq of 352 MHz works. 353 MHz doesn't.

    Third, your VID is a little higher than average.

    This should be your first stop.
    Core2 Overclocking Guide (generic guide that Rolli linked to)

    Next stop should be Shadow's Gigabyte motherboard OC guide:
    It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

    Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 266 MHz, your memory clock should be at 533 MHz.

    Don't try to OC the memory. What little performance gain that you might get will not be worth any loss of stability. We talk about that here:

    That G41 board I mentioned up above? I have an E6500 (same basic chip as yours except smaller cache) running at 3.66 GHz (333 X 11) with a mediocre by today's standards ACF7P cooler. It is stable at 3.87 GHz, but the extra performance isn't needed.
