Overclock being disabled in BIOS automatically

[Bigdogbmx]

Having a bit of a problem with my machine not doing the overclock it was doing 24/7 before. The setup is an Gigabyte P35-S3G, E4400 (2ghz stock), 2GB stick of OCZ ReaperX PC2 8000, Sapphire Radeon HD4850. I had been running it at 300x 10, 1.4Vcore, RAM at 1000Mhz (stock speed, 2.1v all timings on SPD). Now I had to reset the CMOS for something else, and now if I apply the same settings, the machine will start for about 5 seconds then shutoff, then restart with the overclock disabled. It will have the same settings but they arent applied, they are just greyed out.

If anyone has any advice on this I would appreciate it. Im assuming its a sign that the machine cant handle the speed so its being set back to default but I cant see why that would be the case when it was rock solid on those settings for a couple of weeks.

Cheers, George.

My mate had this problem with a gigabyte board. It turned out to be an external usb hdd that was messing things up. Once that was disconnected everything was fine.

Have you added any external devices?

Thats amazing you said that. I just added an external USB drive! AND, tonight I had to do a bit of reorganising to add an internal HDD, and didnt other plugging in the external one, now the overclock seems stable again. Dont suppose your friend managed to find a way to get the external drive to stay working did he? It would be nice to have the drive usable...

Either faulty board or the drive. Try drive in other OCed PC and see if it does anything. Maybe try updating the BIOS as well? that might help.
