That's not what I usually see, my core temps are higher than my package temperature, sometimes significantly (avx workloads for example). 7-8 degrees or so.

It doesn't worry me as I temperatures aren't bad. Just my observation.

I guess its different for different configs and work loads. I mainly game and mess around with a few productivity programs. PC hasn't been restarted for 4 days, Package max: 77 highest core :75.

I only ran avx workloads out of curiousity, not something I really make much use of. I haven't compared package against cores when gaming, think I will later.

I got my 9900K a week ago from Amazon US and thought to share my OC results here. Seems like a got a pretty good chip.

- Lowest voltage (after vdroop) pass on cinebench.
5GHz all cores 1.133v

5.3GHz all cores 1.306v

- 5.2GHz/4.7GHz cache at 1.296v under load prime95 26.6 small ffts for one hour with no whea errors.

- 5.3GHz OC. It can pass one hour of prime95 custom 1344k and AIDA64 (CPU, cache) at 1.363v 5.3GHz/4.7GHz cache with no whea errors

Nice. Worthy chip for ln2 if cache runs higher than 4.7.

I tried 5.2GHz/4.9GHz cache and it passed 1 hour of prime95 small ffts with no whea errors at 1.325v. Haven't tried any higher yet.

Since my system is in bits pending reassembly, i've stripped the blocks to clean them.

I've been running the loop for a month, maybe 2 at the most with distilled water, biocide and inhibitor. Everything in it is brand new and was cleaned with mayhems blitz (following the instructions to the letter) before being flushed and filled for daily use.

When i opened the cpu block i found that the microfins were blocked with black! It looked like threads or fibres, maybe acetal stripped from fitting insertion? Anyway, that explains my temp spikes when i apply load. So I'm expecting my 9900k to be cooler once everything is back together sans blockage. I still need to resolve the issue of the block not making full contact with the ihs.

Looks like another good cpu. Ty for sharing.

Do you get much vdroop? What vcore do you have to set in bios?

moorhen2 · 9 Dec 2018 at 18:11

Not sure what the LLC is like on the MSI boards, but I would imagine the vcore in bios is higher than the 1.325v he states.

For that test I used LLC3 Vcore 1.285v in bios, 1.296v idle and 1.325v under load. All the other tests were done with LLC4 which gives me a little more vdroop.

That means the LLC of 3 is giving more voltage than you are setting in the bios, so overvolting in other words.

On my asrock board i have left LLC on auto and checking my vcore during cinebench shows the cpu volts not dropping as much (holding the volts i set in bios).

I can do 5.0Ghz @ 1.180v and that maxes out @ 1.184v under load.

Mine too was from the US rainforest, seems like they had a good batch.

Hey all. Quick question. Can I set long/short duration package power and package time to max (4095/127) and CPU Core Cache current limit max to max (255) when at stock settings? Probably a bit of a noob question, but just making sure that doesn't do anything like feed it 1000v or anything?

Also, if I enable XMP will that push up my vcore or will it stay the same as it is at complete stock?

Thanks for any help! Starting my overclocking expedition on a z390 now! just want to see the stock results without power limits.

Is that z390?

Mmmm 1000v. That's some tasty power delivery.

No im on Z370

Ah. I had an asrock board, the z370 taichi before going to z390, i didn't get to make the most of it with my 8700k but the power delivery got decent reviews compared to others in the price bracket at the time.

No it won't hurt.

Keep an eye on all the AUTO voltages with the XMP profiles, especially the Vccio & Vccsa

Yeah i have the Professional Gaming i7 so almost identical to the Taichi.

I was going to sell it and get a MITX Z390 board but id be paying more for a much worse board.

Needless to say im going to keep the PGI7 as it runs my 9900K perfectly.

Great thanks. I know it usually gives too high VCCIO and SA was just wondering if it changes vcore as well, if you use XMP?

Was also going to put SVID behaviour to best case scenario to try and lower the stock voltage. It only goes up to 1.270v but was going to see if that helps. Good idea? I thought so.

fornowagain · 10 Dec 2018 at 14:48

I'm assuming this is an Asus, yes?

If its on AUTO it'll be based on VID.

Set it to manual, just watch the overshoot with the LCC level.

Then Adaptive + Offset once you know the stable Vcore needed. Set the 'IA AC and DC load lines' to 0.01. Likewise SVID will have an effect with Adaptive.
