Question on my OC test results 4690k 4.4ghz

[mrfungi]

Hello. Today I upgraded my cooling to a H75 Corsair from a Coolermaster 212 Evo, as I accidentally damaged the Evo when I was cleaning my PC over the weekend So decided to venture into liquid cooling for the first time in my illustrious path of PC Building.

I ran some tests today, with no errors, ending up with 4.4ghz @1.130v, but would like input/thoughts on the screenshots below, as I'm somewhat surprised by the results as through research I've seen people having to go at least 1.2v-1.25v to reach 4.4ghz.

My main thoughts here are I set the Uncore @1.090v, but notice the system agent offset has increased it to 1.116v. I've set both Vcore and Uncore to override, is this an indication I should increase my Uncore slightly as the offset is kicking in?

Here is a 16 minute FPU test on Aida64

Prime95 26.6 10minute Small FFT run

Aida64 20minute CPU/FPU/Cache/System Memory run

I ran 2 more Prime 95 tests, another 20minute full Aida64 test yielding the same results.

Many thanks!

No one?

If 4.4ghz is stable @1.130v then I would say you got a very good chip there, I can get 4.5Ghz at 1.2v stable, I haven't tried lower voltages for lower speeds. Regarding your question about offsets and such, I have no idea, I just use a static voltage, it gives me more voltage than necessary when idle but I prefer that over spiking voltages under load, I hope someone can help you out though as I'm interested 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 here! 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 4.4ghz@1.130v, so I'm happy with those results.

Overclocked some more today and had some interesting results. Tried 4.6ghz@1.150v but immediately hit a BSOD on the first cycle of an IBT loop. 4.5ghz@1.150v, 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.

4.5ghz@1.145v, 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.

I got worst chip possible of 4670k, 4.4ghz 1.3v if go 1.250v i get bsod and cant go 4.5ghz with out above 1.3v what im not going to do
