I7-970 4ghz overclock with no voltage change

post #1 of 13
Thread Starter 
I asked a similar question at Tom'sHardware but didn't get the answer I was looking for.

I OCed my I7-970 to 4.0ghz (4.2ghz originally) - The only thing I changed was the actual clock frequency and nothing else.

I admittedly know nothing about overclocking and although everything seems stable I must know I'm not overlooking anything.

Here's a screen cap on load



Here's one on idle



From the screens alone, my buddy says the voltage is too low and I should look to bump it up.

Idle temps are 28°c on Air - Max temp is 54°c which is maybe 3-4° warmer than before.

These are some components.

Vigor Monsoon III LT Dual 120mm Fan CPU Cooler Socket 1366 Ready - Retail
IN WIN COMMANDER IRP-COM1200 1200W ATX 12V 2.3 / EPS 12V 2.91 SLI
EVGA E758-A1 3-Way SLI (x16/x16/x8) LGA 1366 Intel X58 ATX Intel Motherboard - Retail
24GB of DDR3 OCZ XMP Ready Series


If you can help, or advice, I would greatly appreciate it. And i apologize for my long winded post.

Run some stress testing software such as P95, LinX or IBT.

If one of the tests makes your PC freeze up try raising the voltage.

Realistically for a 4GHz clock you should be around the range of 1.2-1.3v from what I've seen with 920/930/950/960/970/980s.

I got an avg. i7 970 and it takes 1.37v for it to be stable @ 4.2Ghz and 1.44v for 1.4Ghz. Are you running Prime or any other stability program to stress test it?

ya volts seem low. stress with linx, 500 runs max ram . stable after that sell the chip to overclockers they would pay for a chip like that for lnc

Lots of answers in a very shot amount of time, thanks. Haven't tested with Prime and will do asap.

What risks do I run if I keep the voltages the same? I guess that's the most important aspect of my question.

As for the batch # I sold my old i7-950 on craigslist and gave away the 970 box.
However, I did buy the chip for $450 from a kid who was part of the Intel Retail Edge program and had gotten it for free. He advertised it as overclocking at 4.4ghz on air.

What if I drop the OC down to 3.6ghz. Would that be a stable OC without voltage change? I'm really just unsure *** to change in order to get this shiz right.

I would really like to know more about this chip not finding many OC's though
