Unable to post after raising and then lowering memory voltage

Hello, thank you for taking to the time to look at this thread and helping me out.

Basically what happened as the title implies is that I raised the voltage of my ram and additionally changed it to 1066 mhz from 800 mhz, afterwards it wasn't terribly stable when playing games. I then decided to revert the settings to what they were before, after doing this, I was unable to get it to post. I tried the ram, and video card in another computer and both work fine in the other pc. Additionally I placed a pin on the reset cmos pin for 25 minutes and removed the battery for that much time as well to and that didn't help either. I'm wondering if I accidentally "bricked" the motherboard as it is called, anyway thank you for any reply.

Here are the pc's specs:

try resetinjg bios to

Optimised defaults


or simply clearing it by shorting the appropriate jumper pins OR by removing the battery


If that doesnt work , most likely you have friend the ram

Thank you for the effort though. (Meant to add that at the end of the last post.)

Sorry i should have read your first post more thoroughly .


I think its unlikely that you have damaged the mb by raising voltage a little to the ram .


I would check all the power connectors , and then try one ram stick at a time as suggested above

Alright well I'm off to go watch a local baseball game, if anybody thinks of anything I sure would appreciate the input. If not, I'll try to RMA the mobo tomorrow, thanks for any help.
