5950x optimisation advice

Audioboxer said:
Let us know how you get on. I ran CoreCyler again last night as I was wanting to get as many cores on -30 as possible to see if it could work. I had a drop on one but managed to sort it. So Prime95/the script at least seems to be working for me.

This is my HWINFO after a few hours now

One core managed to touch 5.1, but more importantly most around 5~5.05, or at least over the 4.9 AMD wants to claim the 5950x should be hitting.

Thats with PPT 270, TDC 160 and EDC 190.

Temps are still low 70s during gaming (intensive 3D games), but I'm just going to accept the 5950x runs hot and not stress over anything in the 70s during summer. Some stability testing can go into 80s.

i really hope they dont send me the same chip back because i wasn't getting anything anywhere near that, most of the time i was lucky if as many as two cores got a sniff of 5Ghz, in fact 4.9 seemed a stretch for most of them.

What cooler are you running?
 
I had two corsair AIOs fail on my which is why i ended up n with the Noctua, if i ever went back to water it would have to be custom loop so i dont have to repace the whole thing if a pump fails etc...
 
i am currently running with an RTX3060 but my hope is before the year is out and things perhaps get better i might end up with something better as i have a QHD monitor incoming tomorrow, in that event i might investigating putting in a custom loop to include the GPU in it.
 
i have seen a couple of videos on YouTube which talk about anecdotal evidence of higher than normal failure rates in the 5000 series, so my hope is that the replacement will be ok.

I also hope that you are right and the bad chip was perhaps poor binning.

because i have had to go back to my 3900x, i decided to run corecycler on it and sure enough it is flawless which just reinforces my confidence that that everything else in my system is as it should be

I think that's one of the articles i read

the new chip has arrived and has been installed and apart from switching on DOCP, its currently at stock and am putting it through an initial cycle of Corecycler
 
Well, i have discovered that because my motherboard has PBO settings in two places, i need to enter the values in both areas, i had PBO disabled in the extreme tweaker menu and was doing all my work in the AMD overclocking menu but i kept getting hard crashes and the TDC limit hitting 100% despite being set at 200. so entered the same values in both areas and reset the curve optimiser to -10 all cores and doing a run on corecycler, seems to be going ok now and no hard crashes or errors
 
well i have now got to a stage i am happy with, for now, and have cores that are boosting to 5.125Ghz!!

I am getting 4.475 under sustained multicore loads i.e Cinebench r23 but only getting a score of just shy of 29000 where as i know others have had 30k or over, now i know this is a synthetic benchmark but it maybe suggest there is more headroom to squeeze some extra performance out of this chip. My undervolts in curve optimiser aren't as high as i would like but i have gotten to the stage of -5 on one core, -10 on three cores and -15 on the rest and it be completely stables so i will leave at that for just now until i feel the urge to start fiddling with it again.
 
PPT 260, TDC 210 and EDC 190

I can probably drop the PPT and TDC a little because when running a multicore test in r23, i am hitting 90% and 76% respectively on those, but it is running quite toasty when at full load like that but never quite hits 90. At idle its sitting around 35 and under gaming load its usually between 60-70 but my room/office his quite a high ambient temperature right now because this house is too damn well insulated and the heat has nowhere to go, lol.
 
one oddity i just discovered was i tried turning on fmax enhancer and run r23 for a multicore test and sure enough, the speeds were much higher at around 4.65 but the overall score was worse, does that have anything to do with EDC dropping off the grid as a result of fmax enhancer being enabled?
