I have an e8400 on a DFI P45-T2RS with G.Skill 1000mhz 4gb ram.

I've been having trouble overclocking it. I tried 3.3ghz with stock voltage and it bsod on me. I tried 1.3v on 3.3ghz and it still crash. I tried 3.6ghz and it won;t boot to windows.

THe FSBRAM ratio is 1:1. and I happend to have an E0 Stepping of the e8400...

what's going on? aren't dfi supposed to be good? or do i just have a bad one?
please help

my ram is not running anything over 800mhz so I don't have to worry about it. but the dfi bios is a little confusing... and i think it's my motherboard, because DFI released a bug-fixed version of my board that oc like crazy. And yes i updated the bios already.
what should I do?

thanks in advance.

here are bios settings


just set the voltage at 1.3v and try 400x9.

ram= 2.1v and @ 800mhz
nb= 1.24v
sb=1.5v
disable all C1E and other crap except multi-core processing
and pci-e locked at 100mhz

sounds like you just have a really shitty chip because you have done everything you should to overclock it.

But i really appreciate this post because you have already done everything that you should do. Because you read the guides, unlike most people.

Try upping the NB voltage.
I've yet to see an EO that couldn't be overclocked immediately after installation, with the right settings of course.
