**Official e8400/e8500 Retail OC Thread

That is the official Intel spec but nobody around here ever listens to stuff like that.

2.6 Voltage and Current Specification pg.17

The Absolute Maximum for FSBv is 1.45 volts but anything beyond 1.155 volts is beyond spec.

My box says 1.225v max, or is that reffering to the CPU VTT?

On your Intel CPU box you will see the recommended CPU voltage for your chip. FSB Termination voltage is different and is set in the bios.

Ive got a Q750A032 E8400 which seems very poor so far.
Failed prime after 20mins @ 4Ghz with 1.45v
Will start again with lower volts and play about with the GTL volts a bit.

How high is it advisable/safe to go to with NB volts to test max fsb?

post your settings on the DFI thread to try help each other find 24x7 settings

Well i have not got any settings really, just been going about it kinda half arsed so far.
Probably why its not going well

Tried your settings from Dfi club with no luck.
Will read through the dfi thread and look for ideas.

Wow great chip u got there, I needed 1.31v (load) to be orthos stable at 4GHz.
