I'm running a Q9300 / Gigabyte EP35-DS3P setup with 4GB (2x2GB) Corsair DDR2-800 RAM. I have been trying to do some mild overclocking to get a little more performance out of the combo, but the system can't seem to keep hold of the settings.

I can get the board set to 7.5x400 and it will stay with those parameters for a few days, then I will boot up and the machine will halfway power up, turn itself off, then turn itself back on with the basic settings.

I have run Prime95 25.2 for several hours with this overclock and had no errors (yes, I made sure to turn on rounding checking). The drop-back to default values seems to be a random occurrence.

Any help you guys can give me would be greatly appreciated; my full rig is listed below.

Gigabyte EP-DS3P F5, Q9300 (Thermaltake TMGi1), 4GB (2x2GB) Corsair DDR2-800, Radeon 4870, MaxLineIII 250GB, Hitachi 7k250 250GB, Pioneer SATA DVD. Corsair HX620 PSU
 
You didnt mention it so I have to assume the voltages are set to auto.

Give the MCH +.1
Set the memory voltage to 2.0v.

See if that helps, if not try MCH +.2 and memory 2.1V (only if it is XMS memory which is warrantied up to 2.1V, I would not go higher)
 
Please disable the Legacy USB Storage Detect function in the BIOS, if you have an external HDD, then unplug it. The problem described by you I saw many times in this Gigabyte P35-DS3L thread, sometimes disabling that option in the BIOS is the solution. ;)
 
yeah my ext drive kept clearing my OC in bios. Took me awhile to figure it out. was a few mobos though :p
 
Hi,
may sound daft however it could be something as simple as needing a replacement motherboard battery it happened to me and a replacement battery sorted it out as the knackered battery was unable to save any new settings and reverted back to stock everytime i tried to overclock and save my settings!!!
