ye, as long as it is stable. run some tests to make sure(i used either Aida 64 and or intel burn test along with HW monitor to check for temperature and stability) the moment it turned off means that its unstable and may require you to either

a.) lower the clock speed

b.) increase the voltage.

 

as i said, higher voltage means more stable overclock.

Sorry that I am kind of a noob to ask this.

So I had this Intel 9900k. It is able to run 5Ghz at 1.215V stably. I read and watched some overclocking guides online, one form MSI told me to run 5Ghz at 1.3V, and a video had me tried 1.25V, then I reduced the voltage a little by myself. But these guides did not mention information concerning to how voltage could affect the overclocking. Should I go for a higher frequency at a lower voltage if possible? I mean is there any point to run 5.0Ghz at 1.3V when I can do 1.215V? I think lower voltage is related to a lower temperature, so should I stick with 1.215V or go a little higher?

Higher voltage can make overclocks more stable but will require a lot more cooling.

You should use ''IntelBurnTest v2.54(AVX version)'' @ very high to test your CPU stability.

Not all CPUs are the same, some need more voltage for a given speed, while others need less.

 

Stress testing for 10-15m with Prime 95/smal FFTs should be plenty for finding if you are stable with an air cooler, more than that is a waste unless you are pushing OCs on RAM.

30m-1h would be the longest I would run a stress test for, and only if I was using a water cooler, because water cooling takes longer to reach max temp.

Using an NH-U12A aircooler. The result is stable for 10 min. VID at 1.314V but I set the voltage in BIOS for 1.215V. Temperature is mostly at 53-65C range but sometimes reach to over 70 degrees. I think there might be room to go lower.

Under 80 is good, push clocks higher.

Your GFlops are very low. My AMD 7 2700 does 154 GFlops @ very high. I think you don't use the AVX version.

to read voltage properly, use HWinfo64 and find VR Vout reading.

I am trying to find out what happened now. I just downloaded a random IBT v.2.54, I do not know if it's the AVX version, or its too much RAM slowing it down.

I don't know how safe or shady this site is but I uploaded my IntelBurnTest here https://easyupload.io/0agbob

When I run it, it says "Linepack binary stopped unexpectedly. This could be a result of missing executables, unstable system, or a software bug." So is this caused by insufficient voltage?

It even won't work at 5.0Ghz for 1.25V and 1.3V. Quits right awat. Probably its not a voltage problem.

I decide not to worry about it as long as the clock and temperature is fine.

What's your CB15 score?

Sorry I was out of town for a while. The CB 15 score is 2157

I went higher as Karath suggested, it was stable at 5.1Ghz at1.26V, highest temperature sits at 86℃. I am pretty happy with this result and would not go higher. I just ran IBT again for stability test, but the GFlop is still around 117 at 5.1Ghz.

There is no AVX Version.  This Intel Burn test uses obsolete Linpack binaries.  There is no version of this ancient stress test that supports AVX.  It was developed during the Core 2 days.

 

If you want the AVX version use:

1: LinX 0.9.6 (35000 sample size is good)

Or

2: Linpack Extreme 1.1.1 (with the /residualcheck or /residualscheck command line switch to check for wrong residuals).

 

If your residuals do NOT match (this is a math equation--the solution should be identical on each loop) then it means you are not stable in this test.

Protip:
If you have hyperthreading enabled and you get LOWER GFLOPS in LinX 0.9.6 (or LinEX) than hyperthreading disabled, your RAM timings are messed up (notably TFAW, TRRD_S and TRRD_L).
