CPU 5950X: strangely low benchmarks

Not mine. I don't have money to burn on this kind of hardware. But a mate of mine does, and he's got a bundle of 2x16GB Corsair Vengeance 3200MHz CL16, a Gigabyte x570 GAMING G1 board and a 5950X. With a 3080.

In 3DMark Timespy, he's getting about 11k CPU score, which is worse than the average for many lower models of CPU and much lower than the average for this one. Board's up to date, RAM is running the right frequencies and timings, CPU temps are fine, software's fine, no weird background activity or owt. He's checking chipset temps tonight but I can't think they'd be a problem on that board. Case is well ventilated.

Anyone got any ideas of other things to check and eliminate?

 

Make sure pbo is enabled. Some bioses have a "performance" mode of sorts that turns on pbo and sets all the limits correctly.

 

What cooler? The temps may look fine but it may not be detecting enough thermal headroom to clock to max...

 

RAM in correct slots? Silly, I know, but it happens.

 

Also are AMD drivers installed and Ryzen profile selected? (this may not be a thing anymore, but mention it in case)

 

Use hwmonitor to tell you the CPU clock speeds.

That way you will know if it is being held back, if it's overheating and the cooler isn't mounted correctly and etc.

 

Passing this all along, many thanks. I think the cooler, RAM slots, etc. are all kosher, but idk for sure, haven't seen the hardware in person. It's a 240mm AiO cooler that came with the bundle. I'm 90% sure he's in dual channel mode but have asked him to verify. He's got all the software side of things (drivers, AMD software, etc.) sorted, he was quite meticulous with installing everything he knew he should.

 

Now then,

Its my CPU in question and thank you for all the replies! Ive got PBO enabled, temps seem fine with the corsair h100i and its boosting up to 5ghz. Using 32gb corsair 3200mhz cl16 ram. Checked its in the right slots and its in dual channel mode. The AMD chipset driver is installed, and I have uninstalled ryzen master after trying every profile possible and having very little difference. Bit baffled at this point

 

dump out your memory timings with ryzen dram calc and lets have a nosey but probably its fine and timespy is just not using the chip correctly, the normal one doesn't use all cores well, if you get good results on evrything else I would just shut it down and move on

 

**** me, he went right ahead and used Power Word: Real Name! Boldly done Daz

 

Was just about to say "what sort of a muppet would do that ?"

Hiya Gareth, didn't see you there.

 

Did you resolve this, just noticed my timespy score is around 12k too which isn't great

 

My Timespy CPU score with PBO is about 16k, EDC is limiting my multiscore but get weird scenarios with this Gigabyte board where if I open up EDC to allow PBO to go nuts I get even better multi core but my single core reduces which is odd, so I just leave it capped for now until I have time to look into it.

Things you can check are that you have 1:1 clk speed between Memory and IF, I saw that when I upped my memory clocks the motherboard put a 1/2 divider on my FCLK which is limiting.

https://www.3dmark.com/spy/22731382 (ignore the low 1080Ti GPU score, mine is broken and doesn't work on the full 16 lanes)

 

Oh and Make sure you actually have all 32 threads and there are no legacy/game modes enable in Ryzen master that disable some for game performance.

 

I've tuned my RAM to from 3800 cl16 to 3600 cl14 and had a major improvement I'm now up to 14k. Still not as much as I expected though really.

 

Same as me then 3800 RAM, check Fclk is at 1900Mhz too. I was quite pleased with the 5xxx ability to actually run my RAM beyond the speed I paid for and with 4 sticks, that is really quite good, I'd only ever managed 3333 in the past few years of Zen/Zen+

If that all looks good then run something like Cinebecnh R20 with Ryzen master opened up in advanced mode so you can watch the PPT/EDC/TDC and temp loadings and see if your board is capping your performance?

 

I get a 29k cinebench R23 score. I'm running it on an X570 tomahawk. Good shout on the checking power limits.

 

Board Bioses come in to it, as I have struggle to match my other system

My asrock 570 board runs my 5950x chip much faster than this Gigabyte board out of the box and I have struggled to better the CPU performance of my NAS from my gaming desktop, I thought it would be the other way around considering the NAS is running ECC@ 2933 CL22.

Took some fair twiddling of stuff in bios to beat the NAS.

 

Checking mine I get 31.5K.......but I have just realised it was running 4.7Ghz all core, Doh at normal PBO settings I get 28.5k, so less than you
