Guys, my setup is E6300 + 965G-DS4 (F6 Bios) + 2 X 1gb Corsair value select DDR2 667... im having a problem...

when i hit fsb 320 and above wif vcore 1.375, vdimm +0.2, fsb + 0.1 and mch + 0.2, my computer seems to cant detect my hard disk....

Anyone know why is tis happening and how to solve it?  

I tried fsb 318 and 319 at all stock voltages and it can detect my HD...

Still cant, i tried 105 mhz for the pci-e as u said, my com cant even on.... it just keeps on on..off, then on..off..., then on...offf.

Then i tried 100 mhz and 101, oso same...cannot on. When i change back to Auto, it can boot normally wif 333X7 speed but cannot detect my hard disk

Is there any way to solve tis hard disk detection problem? or any other pci-e frequency i can try?

Hmm, when i set 320 or 333 wif pci-e to AUTO it can on and i hav the speed i want, but cannot detect HD

When i change the pci-e to 100,101 or 105 it cannot on and keeps on (on and off) as i said

This is the Latest Bios i could find from gigabyte website (F6) which im using now

Mine is version 2.0

I've selected start windows normally but still failed to load windows. These are the setting I made :

Where I made a mistake?

MOBO is GIGABYTE EP43T-UD3L

1) For the moment, i'm using stock cooler (with case open and got extra 16" fan blowing it. Planning to buy one. It's either H5O or VenomousX. Still thinking).
2) E8400 EO (wolfdale)
1) Have try to increase the vcore to 1.35v. But failed also.
2) Hmm... that ram voltage is what is suggest by corsair. (i've send a question asking them the voltage if want to OC to 1600 Mhz. It's also written on the ram that voltage)
3) 4.0D or auto. That's the only choice if I set ram to 400 MHZ. If want to lower the multiplier, need to set either 333 or 200 Mhz

You are right. It's the ram setting. I've tried setting :

(G)MCH Frequency Latch [200Mhz]
System Memory Multiplier (SPD) [4.0D]

I can load into windows. Emm... i'm using DDR3 ram Corsair dominator TW3X4G1600C9D. It's wriiten on the ram 1600Mhz 9-9-9-24 1.80v ver 2.4. But in CPUz it's detect as CM3X2G1600C9DHX. Don't know which one is correct.   Now the problem is to set all the voltage. Now i'm setting the voltage to auto coz confuse what voltage need to set.   Do U know how to set all the voltage. (That voltage that i'm setting at first is from a forumer advise on overclock.net).

Thanks a lot for your help and advice.
