High Temps Ryzen 9 5950X?

[VPII]

@affxct and @Duck I will put is bluntly, the AMD zen 3 processors are somewhat different from what you get with most others. It will give you a ton of power but in some ways also limit you in many others. I am no expert but I posted on this forum how to better optimize your Zen 3 processor for PBO. Had many comments, not questioning but all appreciating my efforts.




Now I am no expert, but I do understand how to limit things where needed, such as temps. The only expert I know and have had the privilege of being with and discussing things was @Gouhan. You need to understand one thing about computer hardware, you actually have ZERO control over it, it will do what it needs to do as much as it needs to do and you cannot change that. Yes you can pull the plug or give it less power, but that is about it. I actually wish I could sit down with you guys and show what is possible and what not but that is somewhat difficult.

Again, you’re going to need to monitor the current draw and operating voltage. This sounds peculiar to me. The PBO route is pointless, the all-core makes far more sense. But while gaming, the all-core cannot be hitting 90c. Like no way. Just no way José. It’s a math thing. It just can’t be that a game puts enough Amps through your chip to yield enough heat output to do that.

That was precisely my issue lol, I've since sorted the 90C in gaming, seems like setting the PBO limit to "motherboard" makes its boost like crazy but also boosts heat too.

This is what I'm currently set up with that was giving me the attached CPU-Z results (which I'm quite happy with single-core wise).

Maybe I'm wrong but wouldn't PBO with a higher clock rate in-game be better than all core OC with a lower clock rate?

On the matter of voltages, I've kept my eye on them like a hawk with my other monitor using HwMonitor and from what I saw after startup, had a max reported voltage of 1.5v would bounce around in the 1.25-1.45v with just being idle and then when it's under load would see voltages drop to 1.01 sometimes. Gaming, the voltages would drop to like 1.13-1.24v or so but this was when using PBO limits set to the "motherboard" setting.

Afaik when you do a fixed all-core, it’s should forego MB limits.

Regardless of you being an expert in this matter or not, it is quite apparent that you know more about this subject than I do so I appreciate any feedback on the subject.

At this point from all the research and feedback I've been given, I'm not sure if my CPU is performing how it's expected as originally. I thought this was a matter of poor cooling hence I bought the 360mm AIO but it seems like that hasn't completely sorted things out.

I think more or less the reason I opened this thread would've been more to determine if the hardware I'm using is defective or not as while I may not be giving workloads that will make use of all 16 cores I would at least like to know that if I did that I'm getting the performance I paid for.

@VPII It’s just that I’ve never really had any issues setting up my own or friend’s Zen PCs. There’s never really been any issues revolving around excessive heat or performance issues whether dealing with PBO or fixed all-core. I’m just trying to consider what the logical issue could be that is making his 5950X behave a lot weirder than my 5900X behaved. My CPU did exactly what I expected it to do around every bend. It’s just hard for me to wrap my head around. The individual I spoke to on Discord has tuned hundreds of Zen builds. Like literally hundreds and has done so for the majority of the last year.

I could be wrong, but I still think your block and IHS are not making proper contact.

5950x Overheating

Unscrew the rad part of the AIO and turn it the other way around so the tubes are at the bottom then retest. If it is not totally full then the pump could be struggling to push the water around the aio. Grim5 gave great advice. If the temps rise extremely quickly then it is a mounting or pump...

HI Duck, I am no expert, I am jus putting out there what I have experienced over the past couple of lets say years using Zen processors. YOu not wrong in your questions and I appreciate the fact that you bring it out here for all to see. AMD Zen is not for everyone, you need to have the patience to get the most out of it. I never bothered with PBO until Zen3 as now the performance I get is just about, and I say just about the same as with a manual overclock.

Look I am in no position to question your finding, hell I actually appreciate hearing from another. So thank you.

I'm leaning towards this now too

The problem right now is that I'm not at home till later this evening to actually go and check. Will update once I've had a chance to give it a go though

Have you tried to undervolt it with setting the vcore to a negative offset of say 0.0500 or even 0.0875vcore. This brought down my tempsby almosy 10c.

I’ve tested tubes bottom vs tubes side and it made next to no difference for my 12900K. If it made a difference, then that difference was almost imperceptible. I did want to say though; the part about the RMA chip being cooler might be more of the thing. I wonder if it could be that some chips don’t have an ideal application of TIM solder between the chiplets and the IHS.

I believe I did this and included the undervolt of negative 16 but the performance loss was substantial . Will give this a go with no offset and see how it goes though
