3900x Clocks

I have the titled cpu which I have owned since new (approx Feb 2020).

Am running on an Asus X570 -E motherboard with 2 x 8gb 3600 ram.

I do not overclock and the computer runs smooth and well BUT the base clock is not 38.00 but instead is 37.25 which also results in the fastest single core being limited to just over 4.5.

I am not able to change the multiplier to 38 and am at a bit of a loss as tow to go about recovering the missing speed.

Any one had a similar problem and found a solution?

To add that I run a custom loop. (Max temp has been 67c - usual temps are between late 30's and early 60's )

I have no wish to overclock or run Pbo etc.

Did read that the problem might arise from the board bios and that in time Asus would sort the problem but despite running the latest bios and having updated at least 4 times since purchase the problem remains.

Should I rma the cpu/ the board or both?

Thoughts appreciated :)
 
Try resetting the bios or upgrading to the latest stable version?

Edit: sorry just realized you did this 4 times. Yeah if you can't change it in bios not sure what else you can do. Did you try through Ryzen master ?

Have tried re-setting bios and all 4 I have tried have been stable.

Have tried different monitoring software - all give same result. Am happy to try a different one! ( basically rely on cpu-z and hwinfo)

Did try manual settings - no difference and have disabled spread spectrum.

Disabling spread spectrum did up the speed slightly ( now between 99.5 and 99.7 whereas before it was about 99.3 /5)

As it is all stable & any performance loss is , I read, very small am not overly worried BUT I find it very irritating that the cpu will not run at the quoted speeds!!
 
BCLK was already set at 100 - re-set to 100 but still minimum multi is 37.25 and NOT 38.00.:(

I cannot find any setting which i can adjust to get to the , alleged, lowest speed of 38 x 100 which is what it is supposed to be - anyone got any further ideas or suffering the same problem?

The chip is not functioning in the way it is supposed to - most frustrating!!:mad:

I felt the same with the new bios, auto was giving a few mhz less. BCLK to 100 fixed mine, not sure what's happening with yours.

Could you send a picture of the bios screen you are having this issue with? Maybe we can help further?
 
Strange with my board literally havent touched the 3900x its all on default in bios just set ram to 3600mhz and we all good. the 3900x boosts to 4.6ghz in games and the temp is low 70s
 
Picture might prove a little difficult but I will see what I can do.

Have decided that tomorrow I will set Bios to default , re-boot and then install the new Bios from the Asus website. Will see how that runs before I re-set Docp,make sure that the ram speed is 3600 and turn off spread spectrum. (these three items are the only Bios entries I have ever changed)

So far as BCLK is concerned their is no 'Auto' mode option. You enter the number you wish and it runs it (if it can - as an experiment I tried 101 some time ago to find it would not boot).

Am also considering e-mailing both AMD and Asus support to see if they can help. Probably get nowhere but if you do not try....
 
Decided to watch a Youtube video by Hardware Canucks - "How To Find & FIX Ryzen 3000 Boost Problems" where they set out the problem that I and others have.

First recomendation was to run the AMD Ryzen High Performance power plan rather than the Ryzen balanced plan (which I was running).

Did the change and it improved from 37.25 to 37.75 - I grant you with a small temp increase.

Which power plan is recommended bu users?

In the BIOS set performance enhancer to option 3. This should improve boost speeds.
 
I keep it in Ryzen balanced. I have an Asus mb as well so I can check once my water cooling loop is complete.
Would be interested to know :)

Ta - will give it a go:)

Decided that it is too hot at the moment to give it a 'proper' go so will defer until it is a little cooler. BUT my thanks to all who have posted. I will report back once all complete.
