how can I solve the problem of G / flops so low ?

purchased two X5670 for 50 € each.
we hope to be more lucky

Today the coming of the Noctua NH-D15s hope to recover at least 10 degrees Celsius.

So this is what I've been running for around a year now. Wasn't 10/10 understanding on OC, but now that I'm looking at my settings (3.8Ghz with x5670) I'm thinking my VTT is way to high? Let me know what you all think:




I'm on an EVGA 132-Bl-E758 board.
post #7044 of 7923
Well my EVGA X58 is either dead or damaged (one F3, then one F6, afterwards it goes FF and stays like that, on boot). Picked up an ASUS P6T SE from the parents' PC.

This has been a major disappointment. The stuff that I take for granted on the EVGA board, for example, 186 BCLK, 3000 uncore, 1866 RAM at maybe +100 mV QPI or even less, this board simply refuses to do. Tried the highest safe value for the QPI voltage (1.3475V) but no, it wouldn't boot. Tried 200 BCLK, 1600 RAM, 2400 uncore, same QPI, to no avail. It has only been able to do 160 BCLK, auto multi, turbo on, C6 on, EIST on, 2400 uncore, 1600 RAM on auto with vdroop set to safe.

Updating the BIOS to the latest one didn't help, either.

So, well, is it really like that, or is my EVGA board a miracle, or am I doing something wrong?

punisher64, that VTT is through the roof, the Intel's safety rule is to keep the VTT voltage under 1.35V for daily use, and ven then it's better stay lower than that.
post #7046 of 7923
If he has any luck that VTT voltage might be off. Mine reads the same thing on my EVGA 760 A1 Classified while it's set to 1.3v

The Classified is among the best overclocking boards. Rev 1.1 is better.

Yea I may mess with the OC a bit. What are you all running setting wise? Can someone post a picture of their BIOs? I'm using an x5670

If you reduce the thread count on Intel burn Test to 6, instead of running it at 12.

@punisher64

24x180.5 = 4.33GHz HT off, 1.34v Vcore
+100mV CPU VTT (1.30v) = 3.61GHz uncore
QPI PLL Vcore 1.35v
DIMM 1.65v
IOH Vcore 1.275v
ICH Vcore 1.20v
VTT PWM Freq 370KHz
CPU PWM Freq 940KHz
CPU Impedance Less
QPI Signal Comp Less

QPI multi 22x - 4Ghz

What can high VTT hurt?
