Vcore required for 4GHz?

post #1 of 34
Thread Starter 
Just curious how many of you at 4+, what is your Vcore? I'm curious if my vcore is my limiting factor or if it's something else. I've tried 1.55 and it still won't post to 4ghz./

Very nice voltages. Were these watercooled? Stability tested?

I am not sure what i need for 4GHz but it seems that I need more than 1.46V.

It could be your RAM. How many slots are you using?

 

To elaborate further, I have an overclock of 4ghz with my 965BE but when I used a 4x2gb 8gb package it failed to post and I had to downclock my overclock. When I removed them and used a 2x4gb 8gb package it posted fine.

They were tested and watercooled.
I sold the first one and its aircooled(Megahalem) now, but it needed like 1.3875V(BIOS) for 4ghz
