I have had my DS3 OCed to 2.8ghz for the last 2 months until a couple days ago I turned tried to turn it on and it rebooted back to the default 1.8ghz. I have tried to reoverclock it(also with lower OCs), but it gets to the POST screen then reboots back to default clocks. I have all the voltages set to wusy's guide. I ran memtest-it passes. I updated the bios from f9 to f12(after the problem started). The temps are all ok-idle~25C.~. The system will boot fine at the stock settings. I have had no hardware changes in the last month. I tried setting the pci express at 102mhz as recommended by a few post. Do you guys have any other ideas?

Have you checked memory voltages/timings/memtest. Something must have changed, my guess would be memory failure. You could run orthos/prime95 @ stock to see if your CPU is ok. Basically make sure your hardware is ok. That's all I got.

My DS3 once "forgot" its overclocked settings and wouldn't keep them consistently during reboots. I removed the CMOS battery and let it sit like that for a couple of hours. Afterwards, I loaded everything back to their OC settings and that solved the problem.

Did you happen to plug in a external hard drive before booting up? I have same MB, and when I did that the BIOS consistently reset the overclocked settings (both externals were WD, btw). Unplugging them at startup causes everything to run normally.

Morerevs- I reset my timings back to 5-5-5-15 and set my ram at 1.9 and 2v, but it didn't help. It passes 2 rounds of memtest. I used the intel TAT at 90% for a hour with normal temps.

Rushfan-I am going to try your idea next, I hope it works!

Shadowflit-I have no external hard drives, but I keep a corsair 1gig flash drive plugged in for Ready Boost. I will also unplug this.

Thanks for the ideas guys-

It worked!
I removed the battery for a couple hours and I also removed the flash drive, not sure what worked, but I dont care, as long as it works! I dont think that ready boost thing even helps.
Again, thanks for the help guys!

Ready Boost does help, probably only if that is the bottleneck of your system though. I used it on my old amd 64 3800 laptop and increased my benches 10%. On a desktop with 2gb ram and dedicated video I wouldn't expect anything though.

download newest bios and upgrage it. once you do that goto your bios and at the main screen press alt+f1 and goto fsb setting. make your fsb 380x9 pci@@100 your memory timings at 5-5-5-15 tour memory voltage@ +5,vcore @ 1.5 and try it. that shoud get you to 3420mghz easy. your max overclock will be fsb@ 388 or try fsb 401

ds3s occasionally have problems booting at 1:1, so try 1:1.25, (2.5 mem multi) see if that makes any difference, it does for a few other people.
