I have C0, so maybe you could use some of my settings, just find parallel between DFI and EVGA settings.Quote:

Never mind my statement at the end of the 2nd post, I found I was wrong: http://i4memory.com/f80/cxe-stabilit...tml#post119398
Can anyone give me a hand helping me get 4.0 stable please.
My cpu is a i7 920 D0 , i have it rock stable at the folowing settings , if i try 20x200 i can only get it stable at 1.294v witch doesnt sound right so mutch more volts for a 200mhz jump . Iam watercooled and temps are ok
My Stable Settings for 3.8

Also posted this on P6T Deluxe thread but no luck with replys :(
Maybe your CPU needs that much vcore? If it does, there's no solution for that. If you want to reduce your vcore a little use the 21x or 19x multi's - i7's hate even multi's.
What is the problem with 1.294V for vCore? It is low voltage for i7. :yepp:Quote:

Hey , Iam currently testing out new stuff i learned while reading this thread and the P6T Deluxe ThreadQuote:

Changed : CPU/IOH Clock Skew settings = Delay 100ps
Atm on 11º loop hope it works :>
Maybe the myth from multi is not so myth afther all tho the change in vcore is quite small to justify it i gess .
EDIT : Why do i get More Gflops on Linx with this new settings then with simply having Vcore higher, shoudnt it go down a litle now that my mem is also not on 1600 but at 1527 ?
Old Settings : 51.6551
New Settings : 53.8365
???
I have found clock skew settings can influence GFLOPs. When pc's are dialed in perfectly they deliver max GFLOPs. Raise or lower skew from that 'perfect' point and GFLOPs will decrease. That's my findings anyway and could explain your result.
CryptiK , Does GFlops synchronize with Vcore? :confused:Quote:

Have you checked if you have throttling?
I have noticed that when the CPU is on the edge of stability, GFlops can be a little lower than when given a little more voltage for it to be 'comfortable'.Quote:

Very nice cpu you have got there. Can it do that using a 64bit OS and 4096MB+ Linx?

I was wondering how that was going to turn out. Very nice.Quote:

very good daddyjaxx. Thats mighty good vcore for 4Ghz. Temps seem great too! :up:
My new combo!

The bug of BIOS occurred. :rofl: It has changed into 4 though CAS # was set to 7.
GFlops : to 52.
Damn, Guys I envy you, with my D0 I need 1.44v to reach 4.44GHz !!!
That makes temp of the CPU reach 79c with a room temp of 23c !
My next try will be 4.6GHz under 1,39V!
Hopefully the Board will do this!
emert very nice CPU bro.:up:
1.24v for 4.41GHZ is really good. :up: Batch# ?Quote:

I bought the first one in Germany at that time. But now I had the time to test it right!

Looking really good, how's it go with a more CPU intensive test like small FFT's or Linx max mem?Quote:

That seems about normal. Mine needs just a tad less.Quote:
