My first thought: cheap slow memory

My memory benchmark is about average to good. It's not gamer memory but it's decent.

This bench runs separate tests for CPU and memory so I imagine their CPU bench code fits in the cache.

Ok. Not sure something like this would help: benchmark amd shows bad performance - Google Search[^]

One of millions: CPU bench showing poor performance - AMD Community[^]

Yeah, that one told me to use a particular benchmark software, but that software wants an installer to run their installer. Seriously. And they require you to register with the website, and you can't even use a big three sign on/register method.

It's like they don't want me to use their product. (Cinebench)

So I'm not going to.

The problem with getting millions of likely hits is they may as well be no hits at all. Sigh | :sigh:

G means APU, do you have a discrete video card? If not, then the CL value of the RAM is important. Also important how much of the memory is assigned to the video card functionality.

I have discreet video - an RTX 2080ti, and the memory is set to autoassign to the onboard GPU (which isn't being used)

Could it be that your CPU is throttled in the Windows Power settings?

honey the codewitch22-Dec-21 5:37

22-Dec-21 5:37

I checked that. Frown | :(

Check for thermal throttling. I have seen this on some of my AMD boxes.

Does anyone have any insight here

Not a great deal. But take a look at this: https://www.amd.com/en/technologies/ryzen-master
If the CPU supports overclocking, this tool will allow you to do it from a GUI screen. I think maybe a reboot is needed aftewards, but it far easier than trying to figure out what BIOS settings to change, and/or what's safe values.

Keep Calm and Carry On

How's the CPU temp while running these benches?

honey the codewitch22-Dec-21 19:13

22-Dec-21 19:13

My bench tool didn't track that. I'd need to find a separate tool to use to check

As others have said I will bet it is due to temperature. Is the heatsink dusty? Or loose?

I would check it (CoreTemp is a good program Core Temp[^] )

If that shows high temps and thermal throttling buy some good thermal paste and maybe even a better cpu cooler.

honey the codewitch23-Dec-21 3:15

23-Dec-21 3:15

No, the chip is running far cooler than it really should be under load.

"The chip" or individual cores? Can you see if it is throttling? CoreTemp will give you info on each core. Also make sure your power settings are set to high performance.

It would also be nice to know if performance was better before the bios update.

honey the codewitch23-Dec-21 3:50

23-Dec-21 3:50

Everything. All cores top out at maybe 65C when they're rated for 90-100 under load. Nothing appears to be throttling. Nothing is set to throttle. HWInfo64 gives per core temps, and doesn't have the problem some software has of misreporting temps on AMD

Performance was about the same before the BIOS update. A BIOS update was one of the first things I tried, since I had never updated the BIOS on this board.

The only thing I can think of is this board has a very conservative profile for this chip, in terms of the voltage levels and such that it's using. But then I'm just spitballing. But the chip *does* go to full clock under load. I don't know how much of the OC stuff I can change with this board/cpu combo. The board is a low-mid range ASUS (so like a middling board, or lower end gaming board in terms of performance). I know the chip itself isn't strictly overclockable, but that doesn't necessarily mean it's not being undervolted or something maybe? Again, not sure, just spitballing.

I always thought shutdown rwmp on Ryzen was 95C. All I have is ThreadRippers and they definitely start throttling cores in the high 60's. If you are brave you can download something like ThrottleStop to see if you are both getting accurate temps and if you get shutdowns, but I wouldn't recommend it. Also, full throttle temps should be compared to idle temps.

But yeah, if nothing is obvious, you're probably 'spit balling' untilyou get lucky. Could be a lot of things, like Windows itself.

honey the codewitch23-Dec-21 4:34

I did try setting some profile in my bios to like CM5 Aggressive, but it causes a reboot as soon as the CPU went under load, so I do have *some* control over the hardware/firmware in this respect. I haven't dug around there, because I don't like doing things that could cause a thermal watchdog reset, especially I'd think on 7nm pathway dies. I'm hoping my answer doesn't lie down that path, because I think then my best solution is a better motherboard more geared to tuning everything and better cooling to go with it. I just dumped another $1000 into my machine recently, so I'm not eager to dump another several hundred in right now. This MB isn't really meant for a lot of tuning anyway, and I think it may run very conservative out of the box. It may not be a strictly gaming board. It's an ASUS Prime A520M-K, if that means anything, and it's probably not top shelf.
