Sorry, noob question. How to "play" with the voltage coz I can see many setting for the voltage..... my mobo is EP43T-UD3L. It's suitable to OC? Just to get my FSB to 1600Mhz.

Can I know where to find about the setting coz I'm having problem to OC my PC.

Where I made a mistake?

MOBO is GIGABYTE EP43T-UD3L

PROC E8400 Wolfdale EO

RAM Corsair Dorminator 2X2GB DDR3 1600C9DHX (currently running at 1066MHZ or max 1333Mhz coz failed to OC my CPU FSB to 1600)

Have try to set to auto, but didn't work. That's why I'm confused. Why auto can't working???

When trying to enter windows :

Failed to load windows. First message was:

"The file is possibly corrupt. The file header checksum does not match the computed checksum"

Then I restart again, no more message. Problem to boot Win:

"Windows failed to start. A recent hardware or software change might be the cause.

If windows files have been damaged or configured incorrectly, startup repair can help diagnose and fix the problem. If power was interrupted during startup, choose start windows normally.

Launch startup repair (Recommended)
Start windows normally."

Try to launch startup repair but nothing happened(looks like it hang). Restart again and it hang.

Already tried it..... Same also.

Problem solved. It's the RAM setting that cause the problem. Thank you very much to Clawhammer for helping me a lot.

Performance Enhance [Standard]
(G)MCH Frequency Latch [200Mhz]
System Memory Multiplier (SPD) [4.0D]
Memory Frequency (Mhz) 1066 1600

Can't set the (G)MCH to 400, only 200. Than I can get 1600 FSB and RAM 1600 Mhz

Attach is the screen shoot. For the moment, try all voltage auto except RAM set to 1.8v

Hmm.... where can I learn to set the voltage for my mobo? If there is any guide or specific calculation? Coz now i'm setting my voltage auto. Some reviews says it's not good to put the voltage on auto. The problem is too many setting and a lot of different setting teach by different people. Make me confused. Now i'm switching back to normal coz didn't know the correct setting for the voltage. Mobo=EP43T-DS3L Proc=E8400. Can see my setting in previous post. TQ.
