NB core low? Anything low?

looks good. screenie of temps @ load?

That's some serious vcore to be feeding a 45nm chip...but if you are shooting for 5Ghz as the information suggests...it's your chip.

He's showing his "set" value for Vcore at 1.475V. What CPU_Z reports [idle and load] may vary -- more likely they will be less.

He hasn't said anything about stress-testing.

But he HAS shown that he's using a hybrid-TEC CoolIt Elminator cooler. I wouldn't have thought you could get an E8500 to 4.7 Ghz under most circumstances, though, without raising the VCORE to whatever level his 1.475V setting gives.

He could have an $800 Vapo-Chill phase-change cooler on that thing, but if the voltage is pushed too far beyond spec, I wouldn't sell his E8500 any CPU life-insurance.

I think you could have electro-migration if your computer was located on Europa or Triton (but in those cases, the cold would damage the processor.)

You're almost there:

5.1Ghz

If superpi was a great test for stability I'd be closer to 5ghz than 4. Grats on 500fsb, but get the vcore dealt with and use p95 or occt for at least 12 hours for stability, not superpi.

Like I said, a lot of folks think 1.4V is the limit. Given the mobo's potential, I'd "go there" if I had the insurance-policy of enough chump change to replace the processor in a few months. I do -- but for more pressing priorities.

Who knows? Maybe Intel will release an E8800 after the rumored E8700, and we can all try for 6 Ghz!

These wolfdales will go down in history as some of the greatest chips ever.

I'm 50 Mhz behind you. What are your CPU_Z voltage readings? I'm tempted to bump up another 5Mhz to 10 x 430.

That kind of thinking reminds me of the prescott days A lot of people thought 5GHz Pentium 4 was inevitable...


That said, I need to see some good benchmarks of E8600 with high oc versus core i7 920 oc'd.

Anyone have a link?

I think im at 1.34v or 1.35v (at work right now). I got lucked out with my board and have very little vdroop.

I have the eVGA 780i board, but it's not the "FTW." My CPU_Z voltage reading at idle seems to fluctuate a tiny bit between 1.33 and 1.34. At IBT load, it's about 1.29V.

I'm guessing I could "go there" to 4.3, and probably wind up with the readings you get. I'm just not sure it would matter much, but your observations are encouraging, just the same.
