Ryzen 3600 clock speed problems

[msvelev]

Hi everyone!

Yesterday I got my new parts and put together the following rig:
Ryzen 5 3600

MSI Mortar Max B450

Gskill trident z 3200

Noctua U12S chroma.black

Gigabyte GTX 1660 super

Seasonic 850W 80+ Bronze

 

This is my first Ryzen CPU, I had a 4690K until now and overclocking is strange to me.

When I ran Cinebench out of the box with windows balanced plan, no XMP, no nothing. I got the highest score yer (3405).

When I switched to max performance and XMP, I'm getting around 3390 (margin of error but still it's consistently lower).

 

I downloaded Ryzen Master and enabled "Game Mode" with Precision Boost Overdrive and I noticed my CPU clock under sustained load is bouncing between 3925 and 3950 MHz. My CPU temp normalizes at 73C. The vltage is at around 1.418V

Even when there is no load on the CPU the clock doesn't exceed 4125 MHz. Is this normal?

Shouldn't It be boosting to 4200MHz? Shouldn't I be getting higher scores when my RAM is running at 3200 MHz instead of 2xxx MHz?

stick to balanced power plan and use XMP. Make sure the memory data rate is actually 3200MHz, not somehow still at 2133MHz (applying the profile does not necessarily enforce a certain frequency)

 

Dont need PBO either, not now

that's max boost, the max speed it's allowed to reach. Not max speed it will reach.

Should be. Make sure memory settings actually apply first. CPU-Z should show 1600MHz memory and the timings rated on the memory kit.

Use balanced power plan and make sure the BIOS is up to date. MSI BIOSes are some of the wrist so be mindful of what version you are on

Using the latest. rev 26.

Memory is indeed at 3200 in CPU Z.

I've uninstalled Ryzen Master and cleared CMOS. 
Turned only XMP on and boosted my CPU Cooler fan speed.

It still gets around 3400 in Cinebench R20, which is the same result as before XMP. Maybe the timings of the RAM are really bad at 3200. 

 

I also managed to do a -0.1V offset and got the same result - ~50 points with 10C lower temps which seems nice.

I mean, with 3200MHz CL14 memory guru3d got 3575cb out of R20, so possible that it's just your chip boosting less

My memory has really bad timings actually, I didn't realize it'd matter that much. It's 16 18 18 38. 
I guess that's an OK result then

Will try to tighten the timings in the near future.

it's not that bad (cheaper 3000/3200MHz kits come with that), and it shouldnt make that much difference either as far as benchmark scores go.

Turns out cinebench isn't very sensitive to the ram speed. And the first run was done on fresh windows with only drivers. Other crap seems to slow down the system after that.
I managed to get a ram overclock at 3333MHz with 16 timings and got from 6000 time spy CPU(no XMP) to 7000 time spy cpu.

Can't get it to work at 14 timings at 3200 tho.

Have you tried a manual overclock in the bios? I am running my 3600 at 4.4ghz 1.3375v with 3600mhz 16-18-18-38 ram. I consistently get ~3970 in r20 with a best of around 4020. 

 

I think I got lucky with my chip, but most people seem to be able to get a stable 4.2-4.3 out of them. I definitely saw a bump in fps from stock.

 

 

Edit: Idk why, but I didn't bother turning on xmp, I just manually set ram speed/timings in bios

dies in a 3200mhz  cl16 memory typically require loose timings in other to reach higher frequency, especially tRP and tRCD

this could degrade it at a noticeable rate

Oops! I meant 1.3375, just under 1.34

 

My daily OC is 4.325 at 1.288 though.
