The voltage reported by CPU-Z during a load test (like Prime95).

Turtley, I use cpu-z to monitor cpu voltage and speed, or I use cpuid HWMonitor for both voltage readings as well as temp readings for my cpu, the individual cores, plus lots of other stuff. Like Kenny said, you run this while you run your stress test, be it prime95 or whatever. I often use the stress test OCCT which has voltage and temp monitoring built into the test.

I use Speedfan as it reads the temps and also displays the core usage. I usually have Speedfan and MSI Afterburner open all the time, though for CPU stresstesting/benchmarking I open up CPU-Z.

That's what I thought but was puzzled by the "as seen in windows" statement.

I use CPU-Z and sometimes HWMonitor for VCore voltages.

I use RealTemp as well.


Thanks!

5G? Actually, it's the other way round, "if I were you" considering you know what you are doing and I don't! True, next stop 48x. However, I know I'm fully capable of turning this CPU into a flashbulb too, so slow and careful...

Great thread on a great series of processors! u da man.

I'm having issues setting my RAM to 2133...

This is on a Z77 board but this guide works perfectly for overclocking on it as well. I can't even get the RAM to load 2133 on XMP.

Should I up DRAM voltage or VTT?

I forget what I did when i Oced my ram i will look for my notes cant seem to find them


however i will post a collection of info which anyone can update at will


Disable Spread Spectrum if you want BCLK 100MHz instead of 99,8MHz.




A collection of peoples i5 2500k OC settings
@4.2ghz @1.2v
@4.4ghz @1.2v or @1.25v
@4.5ghz @1.28V or stock or @1.3V
@4.6ghz @1.37v-1.4v
@4.7ghz @1.375v or @1.425
@4.8ghz @1.33v or @1.408v
@5.0ghz @1.344v or @1.440v

Claims
@5.2ghz @1.38V
@5.6ghz @1.54v but only for super Pi and Wprime.
@5.7ghz @1.55v but crashed while running super Pi.
@5.9ghz @unknown only posted

Comments to go along with the i5 2500k OC talk
-should hit 3.8-4.4 at default stock some say maybe 4.5
-Sandy typically needs about 0.04v for each 100mhz increase.

Update. I2700k 47x at +0.085v is good for at least 4h p95 blend, and no hiccups for several days , including a rather large calculation which ran for at least 9h and uses almost all the 16G ram + stores partial integrals to an SSD page file. Excellent advice to this OC n00b from the thread leader and all participants! For regular use, this level OC is saved to the MB.

One question, I noticed during windows start up the Cpuz vcore will spike to 1.368 and 1.372 momentarily. This then returns to idle volts I posted earlier. P95 or dynamics runs never go near that. Is. That something to worry about and try to stabilize, or not? Is that the iPLL overvolt at work?

Don't worry about it. It's just a Windows thing.
