Ryzen 3900X thread

Metalface Mark · 27 Nov 2019 at 11:49

Ive just installed my new Ryzen 3900 (aurus x570 motherboard).

Im absolutely new to AMD - my last being an opteron about 20 years ago.

I seem to be getting pretty low performance going by my cinebench score 5534).

Im guessing its to do with my memory timings - absolutely no idea what the problem is though.

Have you installed latest CHipset drivers and latest 1.0.0.4 BIOS for that board?
Which powerplan are you using in windows?
Are you using Ryzen Master and not the BIOS to enable PBO etc?
What else.................Are you using an old installation of windows or have you got a fresh and fully updated version?

Metalface Mark · 27 Nov 2019 at 12:32

Fresh install.

Updated to latest bios (1.0.0.4)

Im not sure what PBO is (sorry!) Nor Ryzen master

I thought i had chipset drivers installed, but maybe not, so ill try that first, thanks!

You want this booger

https://www.amd.com/en/support/chipsets/amd-socket-am4/x570

Ryzen Master is AMD's own software for monitoring and Overclocking. Many run Ryzen 3000 CPU's at stock. Ryzen 2's arent great OC'ers as AMD have done all the algorithms for you.

For the highest single core scores people have been disabling some cores and OC'ing (manually) the best 2 cores. And for those that want biggest all core scores are manually OC'ing also. But if you are a gamer and casual user then leave at Stock, enable PBO if you want (In Ryzen Master) or Auto overclocking and increase the core speeds (max allowed is 200Mhz) and then it's down to your board temps etc. See what you get. But a 3900X will rip through anything and a great gaming CPU at stock.

That chipset driver should sort thee oot.

Thanks!

Oh, you may wanna re-install gfx driver after the chipset driver - as when I updated to this chipset, my games were a janky mess until I re-installed gfx driver. May have just been my machine.

Test performance again, then download and install the 1usmus power plan (think version 1.1 is latest) and switch the windows power plan to that as well as making the small BIOS settings changes. It does make a big difference.

Metalface Mark · 27 Nov 2019 at 13:36

Retried after running chipset drivers but its still coming up slow - (6585 on multicore, i reckon it should be about 7000ish) but maybe im wrong.

SiDeards73 · 27 Nov 2019 at 13:42

What ram are you using? is it C18 3600mhz? as that seems a bit slow.... Ryzen loves latency rather than pure mhz speed, so if you can dial it back to 3200 and C14 or something you'll probably see a decent uplift.

Like others said, download the 1usmus 1.1 power plan, make sure you set all the BIOS settings, go into Ryzen Master and set the plan to Default first and then test, this will turn off PBO and Auto OC, then you can try enabling them and compare against your stock settings.

KungFuSpaghetti · 27 Nov 2019 at 13:48

I would deffo look at the RAM timing and see if you can tighten it to CL16 using Ryzen Master. Not sure what your memory is, if it's Samsung bdie you can try my settings, I get 7297 in CB20 with just my desktop loaded up and all apps running in background(discord, steam, R* etc) and think my 3900x is one of the weaker examples.

Ive done the power bits and still only getting 6454. Can you change the memory timings in ryzen master or you have to do in the bios? This is what im currently showing for memory.

oweneades · 27 Nov 2019 at 14:18

Looking at your original screenshot with the XMP timings it certainly looks like RAM is a factor.

18-22-22-42 is pretty slack at only 3600.

For reference the RAM I ran with my 3900X was 3200@ 14-14-14-31. From memory I was able to run it at 3600 with the same timings although this might have been on my Intel setup.

See if you can run say CL16 (16-16-16-36) @ 3200 or even 3000 and see how the score reacts.

KungFuSpaghetti · 27 Nov 2019 at 14:19

I've never tried changing timings in Ryzen Master, would only ever really consider changing memory timings in the BIOS personally.

Metalface Mark · 27 Nov 2019 at 14:32

i notice on core temp that my multiplier is showing at 99.75 rather than 100, but its set at 100 in the bios.

My all core boost when running cinebench is only hitting 4ghz, is that right?

Try enabling pbo,xfr in bios, should hold 4150+ MHz allcore ( cooling permitting )

i just tried everything on auto in the bios and now all of a sudden im getting 7050 on cinebench 20.

Happy enough with that just now anyway! Thanks for all the help, will see how it goes with some games before pushing for more.

That's a more normalised score. I would highly recommend using DRam Calculator and tightening up those rather loose memory timings.

Thanks, will have a look at that.

With PBO off, correct RAM XMP settings (3600C16) and everything on auto you should be looking for 7100-7200 on CB20 cooler depending.
Make sure you have later bios installed, only XMP active for your ram, everything on auto, no Ryzen Master, latest chipset drivers before you run CB20 and tell us the score you get.

Metalface Mark · 27 Nov 2019 at 21:13

So from playing tonight it seems to be voltage dependent. run it on auto volts i get about 7000, run it set in bios at 1.25 it drops to about 6600
