Temps way lower on CCD2
Click to expand...
CCD1 showed a maximum of 90.5 C, whereas the CCD2 screenshot shows a maximum of 85.0 C, but at a lower frequency (4536 MHz vs ~4668 MHz). Some variation in CPU temps is expected, but given the reduction in clock, the temps seem probably about expected. I don't think it suggests any problem with CCD1 other than your getting to enjoy PB2/PBO in all it's glory (thanks AMD!)

I haven't run P95 for a very long time, but I did a test on mine just to see. I think I used the same settings (1344k FFT, AVX2 enabled, 2 cores).

Hwinfo

Looking at the data, it appears I'm getting about an extra 40-50 MHz. Peak CPU temp was 68.1 C, settling in to ~67 C after a minute or two. I didn't close any background tasks so my CPU load was a little higher at ~2.8 average cores, but average core power was still only 52 W (looks to be about 20% lower?).

The difference is I have PB disabled and I'm using profile switched undervolts instead. Given the 20% lower power, more clock and 20 C lower temps, you probably see why :p. My 5950X was exactly like yours stock.

I wouldn't be fixating that much on comparing the maximums. Since this temperature for CCD2 was very temporary - the initial boost is always higher and then settles a bit below the max boost. I would like to point out the difference in current which is where the temps are hoovering under load after a while (also ignore the average column as thats average since last min/max reset and will include idle before I started the test).
I believe the difference in current is quite high. especially keeping in mind that CCD1 is capped by that temp (throttling). If the cap would be lifted you would most likely see it going higher.

Your point about clock difference is nullified by the fact CCD2 gets a bit more voltage and overall core power usage when on CCD2 is actually a bit higher than the same load on CCD1. Overall the power is comparable between the CCDs.

I guess what I'm getting from all the replies so far is thats pretty much what is expected for these CPUs which is a bit disappointing after not having such problems on 3900x (never getting anywhere close to throttling).
I was also probably expecting more from Curve Optimizer. At the same time it does give a notable difference - the cpu on default looks even worse thermally.

I do like your clock/temp/power tuning. Is there a guide on doing these profiles?
 
I have this kit installed with my 5900x

Team Group 8Pack Edition 16GB (2x8GB) DDR4 PC4-25600C14 3200MHz Dual Channel Kit - Black

Would I be able to buy another identical kit to take it to 32GB and possibly run the 4 sticks at 3600?
 
is there a really good guide for manually overclocking the 5950x guys? I seem to be having some weird issues with mine all of a sudden set to auto. It used to boost itself to 4.9ghz on most of the cores when gaming, but all of a sudden it's dropping clocks to 3325mhz briefly and now I only see cores jump to around 4600mhz. Also the weirdest thing ever, when I bench Firestrike, Timespy, Cinebench or even the CPU stress and Bench in CPUz, none of my core clocks boost higher than 3325mhz, they are all just locked there and voltage doesn't budge from 1.03. Something doesnt seem right. I've flashed motherboard but still the same.

Just tried to do a manual overclock as auto doesn't seem to be boosting right. Just an old skool manual overclock, 4.6ghz all core 1.23v 29616 multi R23 test, seems a bit low this does it not?

Its probably ok. I think your doing great for only 1.23v . Mine cant do 4.6 all core even with 1.35v with a weak ccd1.



Using dynamicOC feature I have set each ccd to where they will pass the 10minute R23 multi test with a score of 30495 although It will land nearer to 30800 with a single click run from cold.

Are people still suffering random reboots with their 5900x?

I had two 5900X's doing that, the first one was unstable all the time and the second seemed fine but after 6 months started to go the same way.

If you've ruled out everything else you should probably return it for a working unit, I had to send mine back to AMD as OcUK said it was fine.
 
Ah that sucks, it's my second processor after RMAing the first one, and this one has completely new auxiliary parts built around it (PSU, motherboard, RAM etc)

I know it's likely not the issue but what motherboard are you using. We have 3 Ryzen systems in the house and no issues with any of them. Only mine is a 5000 series however just never had a single problem. We have Asus and MSI boards here.
 
I moved to windows 11 last week and it's a pain in the hole tbh. (direct upgrade from win10 to 11, not clean install) Printer software needed replacing, my Virtual DJ software doesn't work now, sidebar monitoring software for cpu and gpu doesn't work any more. Beginning to regret the move, it's been a ballache so far.

I had quite the opposite experience, I had been dreading it for months as I use my PC daily for work so was concerned about all the IDE's etc playing ball but other than an issue with Freesync not working for 24 hours (no idea what fixed it) Its been plain sailing. Gutted your having issues, mine was an upgrade from Win10 as well as didn't want the downtime of installing all that software again.
