Ryzen 2700X Throttling?

TheLegendOfMart · 30 May 2020 at 15:04

I have:

Ryzen 2700X stock, no overclock
MSI B450M-A Pro Max with latest bios
Corsair DDR4 3200

This is the CPU cooler - EG GI-X6R 160W CPU Cooler X6 with Red Colour Ring Fan

I can't link to it as it only brings up a competitors shop page. It claims to support 160W TDP.

Everything is stock, no overclocks, all the drivers installed, etc.. I run Ryzen Master just to monitor the speed/temps and when I load all the cores up doing video encoding for example once the temps go over 70c all the cores drop to 600MHz for a few seconds.

I've never had a Ryzen before. Am I doing something wrong or is the cooler not adequate?

I can't find any reviews of that CPU cooler anywhere

AMD stock coolers for Ryzen are OK if you have one?

What case and fan setup do you have? And what PSU?

I don't have the stock cooler I bought the 2700X on MM.

I have a Thermaltake Versa H17 case with dual intake and one exhaust fan and PSU is a Corsair 600W.

Do you maybe have a manual max temp for CPU set in the bios, it shouldnt be throttling at 70oC ? if its set to auto, try and manually set it to 85oC, they are good up to 95oC, but give yourself some headroom.

EDIT: In fact ive just seen you've got an MSI board, the option should be there in the bios.

TheLegendOfMart · 30 May 2020 at 16:35

Can't see anywhere in the BIOS about max temps.

Sorry my bad, I just had a look myself, I couldnt find it either, im sure it was there before, maybe its a option they just removed in later bioses.

Are you on the latest bios, you are not alone with this problem: https://www.hwinfo.com/forum/thread...-thermal-throttling-htc-mean.6073/#post-23154

Have you tried running a benchmark or two, to see if the results are alright?

I ran HWInfo just to see whats happening when I load all the cores. PROCHOT EXT is triggering.

If only PROCHOT EXT is asserted, it means it wasn't the CPU that is overheating, but some other component (most likely the SIO or Embedded Controller) that issued this signal.

Might be worth sticking a heatsink on that Super IO chip or pointing a fan at it just to see if it makes a difference for now.

Failing that, you may need to RMA the board.

It could be your motherboard, while some of the MSI B450 MAX boards are fantastic there are a couple of stinkers.

Is this your exact motherboard: https://www.msi.com/Motherboard/B450M-A-PRO-MAX ?

TheLegendOfMart · 30 May 2020 at 17:14

Yep thats the board brand new.

Gray2233 · 30 May 2020 at 17:17

Try monitoring your VRM temps when you're trying to run tests or do work and see what happens.

Looking at a couple of Ryzen VRM tier lists that board gets rated pretty poorly by most.

There is no sensor for VRM and I don't have a themometer or anything. I will just return it and get a different one.

Thanks for the help everyone.

Best in the MSI range is the B450 Mortar Max in mATX form factor, its bigger brother is the Tomahawk, thats ATX.

MSI came out top in the B450 range from all manufactures by the way, so if you go for another brand, things could get worse.

Gray2233 · 30 May 2020 at 17:24

Yeah, the Mortar MAX is a great board.

Tetras · 30 May 2020 at 17:48

Wouldn't it be prudent to stick a fan blowing on the VRM to make sure it's the problem, before you return it for that reason?

TheLegendOfMart · 30 May 2020 at 18:06

I've already tried that.

The link above to LTT says my board is Tier F for VRM and they recommend 3100/3300X....

BongoHunter · 30 May 2020 at 18:08

Is your Ram set to DOCP or manual - some early MSI Ryzen boards enforced a different CPU temp limit in manual (b350) - I can't imagine that it should still be an issue with a b450 but it's the only thing that springs to mind.

Have you got all the Ryzen power plan bits installed in Windows and upto date win10?

TheLegendOfMart · 30 May 2020 at 18:12

I'm using the Ryzen Balanced Power Plan and RAM is set to XMP Profile 2 (3200), Windows 10 is fully updated too.

TheLegendOfMart · 3 Jun 2020 at 11:19

I got the ASRock B450M Pro 4F which has VRM heatsinks, more fan heads, RGB control, etc.. for £4 more and its working a treat now.
