Getting E8400 Trying to get to 4.0GHz

post #1 of 6
Thread Starter 
Hey I was wondering I am getting a E8400 and I was looking around the forums, trying to figure out what the best FSB/Vcore would be good to get a Stable/Safe 4.0GHz out of this thing?

I see a few have sucessfully done this but don't really share their vcore and settings. I am sure ya'll have answered this question a million times but I figure I would ask anyway.

My E8400 will be in a EVGA 780i Motherboard with OCZ 800MHz SLI Memory. I have watercooling, so no need to worry about temps.

Thanks for you help guys!!! I truly appreciate any help!

Their is no recipe for your CPU and motherboard combination. Now the TT Bigwater does NOT allow you to get sloppy with monitoring temps. I would highly suggest that you follow the steps in my "New member-guide" in my sig and post temps and voltages (during load and during idle). We can definately make suggestions on how to do it, but my main suggestion would be to disable memory SLI and Intel Speedsptep amongst other things. Good luck

Welcome to OC.net (and good job filling in your rig info).
Running DDR2 1:1, PC8500 or decent PC6400 , 9*450=4.05g, prolly at 1.365-1.375vc not including mobo vdrop.
Temp utilities for the Wolfdales are sketchie, so use the highest recorder of them all (CoreTemp) and keep it below 72C.

BTW: Due to the 45nm, vcore voltages cannot match the 65nm chips, or they will fry.
Keep the vcore below 1.365 after vdrop even with H2o. Some have gone higher and remain stable to 4.4g, but many are also fried dead. Your choice.
Google it for additional info.

The 45nm wolfdales dont need WCing since they reach their max vcore before max temps with air cooling. To be safe, keep your vcore below 1.365v. There are already reports of damaged E8400s running at 1.41v and up. Many of the 4.0GHz+ OCs are done with 1.35 to 1.365v so give that a shot.

You will have to run a 450 FSB for the 4.0GHz OC, so you will need 1.5v to both the SPP (northbridge) and FSB voltage.
