Underclocking(?)

[Creatorbros3]

I recently got a Ryzen 9 5950X but made a slight calculation error - mainly in regards to my PSU. It runs stable in most cases, but if it ever engages the GPU and the CPU together and either of them boost (this is my best guess as I've not spent much time truly diagnosing it) it shuts my system down. Rendering from DaVinci Resolve didn't seem to trip it - but it's been mostly basic edits with slight color correction. Doing a sample scene in Blender shut it down immediately though.

I don't think repeated shut downs would be the best for the hardware long term, plus it's just inconvenient. I will eventually buy a new PSU that supports it all fine - but until then I'd like the system to just not boost at all. I've never dealt with over clocking or anything like that. I build a system and run it vanilla. I edit video and photos for my business, so I prefer stability over full tilt, unhindered power. I have an MSI motherboard with a fairly customizable BIOS. So I would think there's be something there to limit boosting. I just don't know what it would be. Any tips would be appreciated.

An additional inquiry, while I'm on the topic sort of: what PSU might you recommend for future proofing. I lean towards Corsair because that's what I have experience with so far and have liked it. Plus the 10yr warranty is a nice peace of mind too. I also like matching components where possible because I have an odd perfectionist mind that prefers a matching system even over performance in some cases. However, I have also heard great things about Seasonic. So I'm open to the suggestions there. I'd like something with enough headroom to support future systems as well as my current one. I could foresee running an RX 7900XTX or whatever equivalent GPU in the future along with a maxed out Ryzen 9 current gen whenever the time comes. It seems like wattage boosts have settled down and efficiency is being prioritized a little more, so it may not take a 1600W PSU or more in the future to have top of the line performance. Right now I've been looking at 1000W Platinum's or Titanium's. Seems like that would be enough headroom for anything I'd be doing, plus the efficiency and quality that it'll last a looong time to work through a couple systems. Share your thoughts. Much appreciated.

I wouldn't be worried about the wattage, I'd consider just in the PSU quality.

A KW one should be hella enough. Do you live in Europe or America (somewhat makes it easier for recommendations)?

7 yo psu, corsair vengeance ram... AM4 the corsair is nothing but a problem, but its opssible the psu's ocp/ovp maybe kicking in, what about motherboard voltage protection, Is that a thing on msi motherboards like it was on asus?

Whoa, what? Is that still so?

no wonder why my friend's PC is unstable :/

USA. Yeah I knew KW would be solid for this - mainly hoped it would be solid for any future builds.

The PSU was well reviewed when I got it. It's not given me any problems so far.

"AM4 the Corsair is nothing but a problem" is this talking about the RAM or PSU?

It has a 10yr warranty. So if it is a problem, I should be able to file a claim with Corsair.

I'm too lazy to give a bang for buck recommendation, but for example, a Corsair RM1000 should be hella good.

5950x PBO tuned can pull 260w package. Stock it does 140w.

A solid RM850x is way more than enough for your build. I had my 7900XTX with my 5950x @260w on a HX850 perfectly fine. I also have a build with a 14900k and 6950XT on a RM850x perfectly fine too.

You don't need to overspend on a 1kw.

I agree with Toothless, a 1000W PSU is overkill and is no use if you don't plan to seriously upgrade your build like for $3k and going for the 5090, AM5 and so on.
You could try a friend's PSU and look if you get the same symptoms, if you can't have a friend helping you could buy a new PSU from Amazon, try, if it does the job ok, if not, just ask for a refund. The Corsair ones are rock solid.

About underclocking, you will have to go into the BIOS and check everything, I own intel CPUs for desktop so I cannot help much (the laptop BIOS my AMD got is kind of...you know, useless). You should love headhaches and spending hours looking at benchmarks xD

The first thing to do will be to check what you have in AUTO and learn what this does, then you want to put the loadline calibration to the minimum (it's meant to be the highest number, MSI tends to put a little graphic so you know, for mine 8 is the value for the maximum Vdrop and so, the minimal motherboard abuse), then you will have to figure (litteraly) what is your maximum CPU voltage (the AUTO value could get you a hint as it's for sure overkill).

From now you want to lower that value, how ? Do you want a fixed Vcore or a dynamic one ? I prefer the dynamic one and it's a pain, if you choose this, you will have a huge pain because it's about offsets, the ultra minimal Vcore while idle which HAS to be stable and every steps of voltage your CPU can use before going at its max power without failing. All this versus something (fixed Vcore) just stable for idle and maximum.
For this step, you will have to guess, trying step by step, not going too aggressive, what could possibly boot Windows as for minimum of Voltage.

When you can finally boot with a stupid low Voltage, you will then benchmark with some heavy useless (not so useless after all) software like cinebench. Prepare to love BSODs or freezes.

Notice that for the voltage, you don't want to be very aggressive, try 10mv, step by step. If you go from the initial voltage you could see in the BIOS, go lower it by 10mV until the benchmark freezes or rewards you with a BSOD. (You will have to try everytime but from the start you could go easily from 30mV lower).

I don't know if as Intel, AMD got the special turbo maximum wattage limit like : Long duration power limit and Short duration power limit. Those things are for limiting the maximum Wattage the CPU can pull to achieve nonsense. When you see you can limit it and have the same CPU&GPU power for 20% less Wattage yeah you can tell it's pulling much for nonsense.

Every chips are differents, you could own 2x the same CPUs, there is like 5% chance you could underclock & overclock them with the same min/max Voltage or Wattage.

At least, if you are brave enough to learn 50% of what is in your BIOS you will earn a lot. Don't forget to enable the XMP feature for your RAM btw if it's not made already. Still you can have hints about what could approximately be the lowest and the highest (for underclocking &/or for overclocking) voltages looking at others' values while searching for your CPU results.

ALL this to say, yeah, go try your luck with a 850W PSU before going crazy.

As a bonus for this wall of text I reward you all with this LEGO MacLaren P1 I saw some weeks ago.

Or they could just use eco mode.

I mentioned vengeance, it is not well received with AM4...

Oooooon the other hand, the Vengeance sticks work @ 2133 on my friend so maybe I just don't care. It's his problem after all....

Exactly my point, the 5800 oem rig with B550 Steel Legend is using Ballistix Gamer 3600 32GB kit at XMP, and I dont think those were on the QVL.

What ? On the motherboard it should just help when the PC is OFF, on Windows it's doing something like nothing
What do you mean ?

That's from OP's sys specs so, as I'm not an AMD desktop user I can't tell for sure but I think the old PSU is failing.

Yeah i was following those and it would seem yes they need to be updated and I am suspecting the same as Im not sure how corsair is on ddr5 for am5...

I wasn't thinking abut the AM5 he just got from the sys specs mentioned...

AMD eco is within PBO settings and it sets wattage caps. 5950x stock is 140w package, which can be turned down to 95w~ and 45w~.

Thanks, I had no clue about this feature =)
