Question about my OC test results 4690k 4.4ghz
Hello. I upgraded my cooling to a H75 Corsair from a Coolermaster 212 Evo after accidentally damaging the Evo during PC cleaning over the weekend. This was my first time exploring liquid cooling in my long journey of building PCs.
Today I conducted some tests with no issues, achieving a 4.4ghz @1.130v. However, I’d like your input and thoughts on the screenshots, as I’m a bit surprised by the outcome—based on what I’ve read, reaching 4.4ghz usually requires at least a 1.2v to 1.25v boost.
My main observations are that I set the Uncore at 1.090v, but the system agent offset increased it to 1.116v. Both Vcore and Uncore are set as overrides. Is this suggesting I should slightly raise my Uncore since the offset is becoming noticeable?
Additionally, here’s a 16-minute FPU test on Aida64: Prime95 26.6 10minute Small FFT run; Aida64 20minute CPU/FPU/Cache/System Memory run. I also ran two more Prime95 tests and another full Aida64 test, all producing the same results.
Thank you!
If 4.4ghz is stable at 1.130v then I believe you have a very capable chip, I can achieve 4.5Ghz at 1.2v stable, I haven't experimented with lower voltages for reduced speeds. Concerning your question about offsets and similar issues, I don't really understand, I just apply a static voltage; it provides more voltage than needed when idle but I favor that over spiking voltages under load. I hope someone can assist you as I'm keen to see the solution.
From what I can gather, System Agent Voltage is to do with the XMP profiles associated with RAM. Found a link

! So now we know! A natural occurence of activating the XMP profile in the BIOS.
Played some games last night after yesterdays tests and it was stable [email protected], so I'm happy with those results.
Overclocked some more today and had some interesting results. Tried [email protected] but immediately hit a BSOD on the first cycle of an IBT loop. [email protected], about 10minutes into an Aida64 test my H75 Corsair fans slowed right down out of the blue! Had all fans set on 100% full speed in BIOS, but when I restarted and checked BIOS, 2 of the fan settings had been switched down to standard from full speed, which puzzled the hell out of me. Set them back on full speed, and downloaded Speedfan to keep an extra eye on fan speeds and percentage.
[email protected], fine after 4 IBT 10minute tests, but 10minute FPU test which kicked out some weird sensor readings in HWMonitor (ridiculously high fan RPM as you'll see below as well as picking up 3 additional fans that aren't there). I dropped the Uncore from 1.120v to 1.100v, had a feeling it was a touch too much, and decided to run further 30minute FPU test after this and it was fine.
FPU
And finally a full run of CPU/FPU/Cache/System Memory/GPU 1hour 15minute test on Aida64.
Fulltest
Everything running fine so far. Gaming will provide the ultimate test for me.
Guess this is a very good chip like you said! This has the potential of overclocking further, will attempt to do this at a later date.
