I'm treading in 5.1GHz territory and stable so far

[tincanalley]

Okay, so the replacement 9900K is much better than the last.  The last one wouldn't do 5GHz stable, no matter what I tried.  This one has been stable at 5Ghz (no AVX offset) for a few days now and passed all stress and benchmarks I tossed at it (with the exception of AVX Prime95 small sets and Small sets in OCCT 5.1.0, but those were heat issues).  I am now testing 5.1GHz (no AVX offset) with a voltage of 1.295 and so far so good.  I need to set the stress tests for longer runs to be sure, but preliminary runs of up to 30 minutes were successful.

I'm going to post the screenshots of the Cinebench15 and 20.  Have to wait for my next runs of Realbench, OCCT and Prime95 for screenshots of those as I forgot to take them before closing out. 

 

I seriously doubt I'll be able to go higher with my current Corsair H115i cooler, but if 5.1 remains stable, I'll be more than happy to stay at that speed.

That's a great overclock if it was me I would try and go as high as I can

gj, I managed to get to 5.1 on my old 8600k. 1.4v though, at least there is a tiny bit of improvement with CFL-R

So I ran Aida64 stress test on memory, cpu, fpu and cache for 2 hours and it remained stable with a max temp of 92c for brief moments.  Realbench ran for 45 minutes without error and next on my list is OCCT.  If that one passes, I'm going to certify 5.1GHz as stable and push a bit higher.

Well I want to push for 5.2, but I will need better cooling for that to happen.  Instead I am going to sit at 5.1 for now and have boosted the uncore to 4.9.  This increased my scores in Cinebench 15 and 20.  I'm hoping to see the same in other benchmarks.  I tried to push it to 5.0, but windows blue screened shortly after login.

 

You have to compare the scores from the previous posted images as these are a couple iterations in my testing and they don't show the true bump in score.

That cinebench R15 score is terribly low for 5.1 ghz.  Not sure about the R20 score.

I score higher at 5 ghz (2200+) than you do at 5.1 ghz.  Make sure you're not running strange stuff taking up processor time.

I can score 2215 at 5 ghz and 2245-2258 at 5.1 ghz (depending on how the system feels).

Yeah, I should check.  I disable active anti-virus, but I wonder if having CPU-Z and HWINFO running during the test is bad.  I'll check all my processes.
