Zen3 Overclocking Results

So i've been overclocking my 5600X to see where it all ends up. If you want to compare your system, my full specs are in my signature.

 

Sadly i can't get 4.8Ghz all-core stable, even with 1.5V. (I wouldn't run 1.5V 24/7, but i just wanted to try out if the CPU can handle 4.8GHz at all)

I get random shutdowns in load scenarios and temp is getting close to 90°C.

 

I've got 4.7GHz all-core stable with 1.3125V Vcore.

Load temps are around 70°C

No crashes in a 6 hour Cinebench R20 loop and no crashes yet in any of my games.

 

I've also managed to get my Crucial BallistiX Memory down to cl14 at 3600MHz and 1.45V DRAM voltage.

Fully passed memtest86 without spitting out any errors.

 

Cinebench R20 multicore score stock: 4350

Cinebench R20 multicore score @4.7GHz all-core: 4630

I have yet to measure the performance impact of my memory tweak, but afaik Cinebench R20 specifically doesn't really care all that much.

 

 

If anyone of you have made any experiences with overclocking your Zen3 CPUs, i'm interested in where you ended up.

Let me know!

If someone did not use reason to reach their conclusion in the first place, you cannot use reason to convince them otherwise.

Maybe you can go higher in memory frequency and FCLK?

 

btw keep in mind that Ryzen CPUs can do some clock stretching, basically means when overclocked too much, the benchmark score actually worsens compared to a slightly lower frequency setting even though it doesnt crash.

Sadly i get shutdowns when going above 3600MHz. Any way to find out if this is related to the higher FCLK that comes when i increase the memory clock or if it's just the memory itself becoming unstable? For whatever reason i can't seem to find a setting for FCLK speed (or voltage for that matter) in my BIOS to decouple it from the memory and test it out. I had it in my B450 Tomahawk in the past, but i don't find it in my B550 Aorus Pro BIOS.

Yeah i noticed that with my former 3700X. When decreasing the voltage the clocks actually went up, but performance went down.

 

Thanks for the reply!

MSI actually released a beta bios fix for the issues with ryzen 5000, people couldn't boot higher than a certain point, but the bios fixed that and they can get 3600mhz cl14, whereas before it was 3200mhz

I'll keep an eye on the Gigabyte page to see if they release any BIOS updates. Thanks for the tip!

Even when i can't push the memory any higher, 3600MHz cl14 is already pretty good.

yeah, I might get 4000mhz cl18, and I'll try to oc that to cl16

and maybe you can get 2 more sticks for 10% performance gains
