overclocking problem...

[wol-va-rine]

I had my E6600 running for about a year at 3.00GHZ and now all of a sudden recently it wouldn't post, it would just get past the Gigabyte boot up screen and then turn off, and then turn right back on again, after this happened a few times with me lowering the overclock a little bit each time I just put it at the stock 2.40GHZ and it booted right up...

what would cause the overclock to all of a sudden just not take anymore...? I was thinking it may be a power issue...? could my psu be going bad...?

You could have chip degradation.

You could have chip degradation.

yeah, that also entered my mind as well...

a month later I finally decided to try to fix it and scoured teh interwebs for a solution, I also remembered flashing my bios to the most current one around the same time that I noticed the problem...

it seems my board (Gigabyte GA-P35-S3G) will only overclock using a certain older bios (F3a), I flashed back to that older bios, the one my board came with, and now I'm back to being able to OC...

weird...

might be something to do to make the board compatible with newer chips that screwed the overclock up for the older ones.. glad to see ya got it working again..

Try unplugging all the USB devices. My EP35-DS4 will not go from a fsb of 266 to 267 with more than two usb devices, but will do a fsb 444 with a little tweaking with the usb devices removed.

This seems to be a not uncommon problem with Gigabyte boards. Some boards have been fixed with a bios update, but not yet for my board. If have read a USB card might allow USB devices.
