Ryzen 9 3900x help/advice

[Railwayman]

Hello people

Need some help please, my specs

3900x
MSI x570 pro carbon motherboard
32Gb Corsair Vengeance 3200Hz DDR4
Cooler master liquid lite 240 Aio cooler
Rtx 2080S GPU

This is my first Ryzen machine and whilst I have no intention to overclock the CPU, would like to slightly lower the V Core which sits at 1.494v on auto without loss of performance.
Have only had it a couple of days and the only thing I have altered in BIOS is to set the fans to Smartfan which has lowered the noise greatly. Not a overclocker but can follow simple instructions and find my way around the bios.
Any tips you can give me would be great, maybe simple ram speed increase or just let the motherboard get on with it.

Thanks

have you enabled the XMP profile for your memory? then maybe force 1T on the memory timming.
also try a vcore offset and - (minus the voltage) around 0.0125

 

[Railwayman]

Thanks for reply, XMP is enabled, lost me on 1T lol, little more detail would be great (noob at this} Will look at offset vcore

Sometimes is is called Command Rate, it might already be set to 1T, but if at 2T its worth changing. Will be in the RAM settings somewhere, cant really advise exactly where tho.

Just had a look and yes its set on 1, my timings are 16-20-20-38, could they be tighter? What would the offset vcore be called on my system? Thanks for all reply's guys.

 

[FireTwo]

Have you run CinebenchR20 yet with a program like HWinfo64 to get your Vcore at load?

maybe best try that make sure all stable

leave timings for now boost MHz is more important.

What is your fclk MHz speed? Guess 1600mhz?

 

[Railwayman]

Will take a look little later thanks once again

is this your memory?

as this states:

Tested Latency
16-18-18-36
Tested Voltage
1.35V
Tested Speed
3200MHz

wont make much difference but maybe you need a bios update on your motherboard?

maybe check what version yours is vs the latest found here

Hi yep that's my ram but mine is 4x8GB, bios is latest on MSI web site. Apart from beta one.

 

[Railwayman]

Not run a bench mark as such but have used HW monitor whilst playing a demanding game and the temps don't seem bad, chip set 65c, cpu about 60c ish etc. Idles around 27c

 

[r22snapper]

Your voltage is normal under low loads, it is perfectly safe and expected behaviour to get the highest boost clocks. Download Hwinfo64 and Cinebench20, run the benchmark which will stress all cores and look at the processor voltage while it is running. It should reduce to less than 1.3V under load.

 

[Railwayman]

Thanks for that will give it a go.

 

[Railwayman]

Took a look at my DDR settings in the overclocking part of my Bios, I have 1.35v on the ram and thought to try just nudging up the frequency from 3200Hz to the next setting with no other adjustments, before I do a little reassurance from a kind soul would be welcome.

Leave it to auto. 1.494v is the low current voltage. If you push the CPU you will see goes bellow 1.26 and nowhere near 1.494 except for the milisecond it needs to boost from idle, without using any current.

Thankyou

Correct, I had mine undervolted and it would only boost upto 4.5ghz, ive set the core voltage back to stock now and its once again boosting back up to nearly 4.6ghz, I was loosing quite a few points in single core CPU-z benchmark, they are back upto 551 now, all is right in the world again now......well nearly.
