5900x - Low CPU score - 3DMark

[xPETEZx]

Hey Guys,

I am wondering if I am missing an 'obvious' setting which might be limiting my CPU score on 3DMark timespy?

I am running rig in sig. My 5900x is undervolted using PBO2 on a -30 curve.

My best CPU score so far has been 12000.

On other benchs at these settings I get:

R20: SC: 620 | MC: 8220
R23: SC: 1600 | MC: 21k
CPU-Z: SC: 680 | MC: 9700

If I move the power limits up, all the above benchs improve slightly. R20 MC up to 8660 and R23 up to 22k. CPU-z goes up to 9900.

However the needle does not move at all on 3DMark CPU, stays exactly the same.

Clock speed indicated on the results page is 4.9Ghz:

I am curious why none of my changes seem to change the score, while in other benchs it does.

While browsing results I found these 2 interesting score: https://www.3dmark.com/compare/spy/19705842/spy/19709725#

What strange is that CPU clock looks identical on both, yet one is nearly 20% higher score.
(RAM is the same on both too)


So Im interested to hear if others have had seemingly low CPU score out of there 5900x, and manged to fix it?
I know people point the finger at RAM a lot, and Im open to it being my Single-rank 2x16GB Crucial Ballistix 3600cl16 kit. It still leaves me wondering about the above score... as there RAM is the same number/clocks between both runs.

If you’re using a ASUS motherboard make sure ‘install armoury crate’ is disabled in the bios. I had it enabled on my board, installed windows, it downloaded broken versions of the ASUS utilities, installed a bunch of crap at the same time and gimped any benchmarks I ran. I had to reinstall Windows to fix it.

Using an MSI board. The Dragon Center software is hot garbage too, but does not seem to affect anything. I tested using a spare SSD with a totally clean install of W10 (and no tools like iCue, Dragon center etc) and scores where about the same.

Hmm yeah your CPU score is less than my 3900X, something up there. Have you tried going back to stock settings for the CPU?

Yea stock settings on the CPU is a bit lower still. Likewise in Cinebench/CPU-Z etc. Its very frustrating seeing reviews of the 5900x, with on paper the same RAM config and similar board and yet there bone stock scores are better than my tweaked ones... :|

My RAM is running using its XMP profile, so 3600 16-18-18-38
On AIDA64 Trial that gives me 52575MB/s and 65.8ns

I really want to avoid manual RAM tunning, that's an alien art to me.

Just for tries though, I just used my boards "Memory Try it" settings to run: 3733 16-18-18-38, which booted fine (its such a minor increase...) which bumped AID64 to 54357MB/s and 62.5ns
Didnt move the needle really on 3DMark, within margin of error.

I also tried Try IT up to 3800 16-18-18-38, but that didn't boot. Despite the "try it" name, I needed to clear CMOS to get back to booting. And TBH, its the reason I cant be bothered with memory tuning. To much reboots and fiddling settings I cant grasp.

My ideal would be to run everything stock/XMP and just be hitting the "default" scores the reviewers seem to hit.

Id be open to changing my RAM for faster / Dual rank stuff if that really is the 'bottleneck'.

So long as its not erroring then I wouldnt expect the RAM to be the cause, those timings should be ok.

When you monitor HWINFO is the CPU boosting/running at roughly normal levels?

I think so, tends to go to 4.3Ghz - 4.5Ghz multi-core, and about 4.9Ghz single core. Seems about where it should be?

Your R23 scores look OK.

Yea its only a bit below what I see the reviewers get stock (about 24k?) its why I am so confused why my 3Dmark score is so low.


Anybody have any clue why the 2x scores I linked from IgorsLab would be so different at what looks like idential clocks / ram etc?

 

[xPETEZx]

Yeah, I cant really think what it could be. Those frequencies are faster than my previous gen Ryzen but the score is lower.

Could it be any of the settings inside 3dmark?
Do you just launch it or do you force 32bit/64bit, I just "launch" it (assuming running from Steam)?
Do you have anything else running at the time?

I just launch it via Steam. I only have the Demo, so cant actually change any of the settings anyway.

I have nothing else running but system stuff. To be sure, I also did a clean install of Windows 10 on a separate SSD. On that I installed nothing but essential drivers (no utilities or stuff like Dragon Centre etc) and the scores on that where about the same. (Which is good in a way... at least means my main Windows 10 install is good.)
