9900k low timespy score

coach7290 · 23 Nov 2020 at 12:00

Hi guys, I know this might be the usual boring thread about performance issues, but I'm struggling understading why. I am scoring in timespy on the cpu test around 10000, with all cores on 4.8ghz. Looking at the stock expected results, I should score at least 1k more. I'm running a 9900k on a z390 gaming plus board, and during stress tests in Xtu the cores never hit thermal/power throttle (they are steady at 4.8ghz with max temp of 75). What else can be the issue? I've always had underperforming cpus on this system (my 9600k was underperforming as well).
THank you

look at your memory speeds, can change a lot in timespy with slack timings.

I thought about the ram, in fact I'm having the memories running at 2399 and xmp profile make bsod the computer (so I always left them at nearly stock speeds). I have 2x 8gb corsair vengeance lpsx. Do you think ram can impact a cpu score?

Yes it can impact CPU score, you need some 3600mhz memory in there, good timings and you will see a big diffrence.

Have you enabled MCE?

coach7290 · 23 Nov 2020 at 16:26

Sorry I'm not very skilled in this. Under msi mobo is multi core enhancement? Should be on or off?

coach7290 · 23 Nov 2020 at 16:27

Alright, I've ordered some corsair pro rgb 3600mhz, hope I won't have troubles with them to enable the xmp like the lpsx.

Should be on if you want higher all core boost.

But if all cores are set manually to 4.8ghz and they don't throttle is pointless, isn'it?

Yeah if your manually overclocking all the cores then just disable MCE.

Since your overclocking all the cores have you also overclocked the cache?

coach7290 · 23 Nov 2020 at 17:52

actually I did use a preset on msi dragon center "extreme perdomance" and it did this overclocking automatically. But I don't think is a fake oc, because the cores are really all to 4.8ghz and they never decrease(like for example with the only gaming boost enabled". So I don't know about the cache if they tweaked that as well.

I would uninstall the dragon centre stuff and just stick to manual OC in the bios as that could even be the reason your scores are lower than expected.

Ok so i disabled the dragon center extreme perfomance mode, and now manually oc each core to 4.8ghz, I'm hitting the power limit on xtu (and they throttle down). I will try to increase the power limit and time window (but I guess it's what that preset was doing)

edit: same result, so That it's not the core performance the problem
edit2: I did manually oc all cores to 5ghz (90 degrees max temp, but they didn't throttle) and still i'm getting the same score (10000). So there's defintely something wrong here

Have you tried cinebench R20 to see how your score compares in that?.

on chinechench r20, I'm doing 4815 (tested it right now)

That does seem about right for 4.8ghz.

Don't forget to also crank the ring ratio, 4.7 should be pretty achievable on most chips.

Thanks, I will try it. So in case are the memories the culprit for timespy, is possible they make big difference here and not in cinebench? (I redid cinebench this morning and i got 4840)

Have you tried a few stress tests. Sometimes if it's not stable you'll get a low score

I honestly didn't try long stress test with Prime95 or something similar, but if those cores looks stable within cinebench/timespy it's not enough to get a good score there?

That board is pretty inadequate for a 9900k. While you can probably get some more out of it, trying to push it to a decent level won't be a good. The VRM layout of the board is very low end.

You basically have a strong engine sitting in an inadequate chassis. For comparisons, a well tuned 9900k does high 13k to low 14k in TS CPU.
