Overclock Ryzen 5 5600 (No X)

[Rydeon]

Hi guys, in my second build I have a Ryzen 5600 and I think I have a Golden Sample in my hands. I wanted to discuss with you to understand if there is still room for improvement even though I doubt it.

As soon as I got it, I immediately created a PBO profile with custom TDC EDC PPT and curve optimizer. For fun, I set -30 on all cores and increased the boost limit to +200 MHz, reaching 4,650 MHz. When testing on Cinebench, I immediately saw that it was boosting consistently to 4,650 MHz even during the test, maintaining a temperature of around 55 degrees in full load. From there, I started testing with corecycler, OCCT, and anything that could bring out errors. NOTHING. The CPU showed no signs of weakness, no errors, and no random restarts. Of course, I am aware that -30 on all cores is unrealistic for most CPUs, but this chip I believe is the exception. We're talking about tests over 6 months, not two days, just to be clear.

From that moment on, I decided to discard the PBO for the limit of 4,650, as this chip can give much more. Without documenting all the tests, I found stability at 1.35v LLC5 (on Asus mobo) 4.8 GHz all core. Again, any test passed without any problems, with the highest temperature recorded during the various tests being 72 degrees.

I decided to push it further, finding stability at 4.85 MHz but I would have had to raise it to 1.4v to make it 100% stable under any load, but it didn't seem necessary. In medium/light loads, even in video games, I was able to keep it stable at 4.9 GHz at 1.38v (No cinebench, only OCCT on medium/light loads).

5 GHz with any voltage doesn't even get into Windows. I also tried with BCLK, but nothing.

My question is: Is there a way, a custom BIOS that removes the 4,650 limit of PBO? I would like to try it to Boost it to 5 GHz. The CPU always maintains very low temperatures. It's absurd!

Also, what do you think? Is it actually a Golden Sample or can most of these 5600s push this far?

Thanks to everyone. Sorry for my bad english.

there is no golden sample 5600, because a 5600 is just a bad 5600x that's been capped.
most 5600x's will do 4.85Ghz with a simple voltage bump, and a good chunk will hit 5Ghz

Fmax is what they call the PBO max clock speed and when I enable the Asus Fmax option in the bios and set the boost override on the same page to 400 my 5950X has CCX 5251 in the Ryzen Master Home screen. I read it had been programmed to allow a 400 increase but evidently not so for my CPU but it's showing 1 more than the 5250 I get when using AMD's PBO bios settings which could suggest they subsequently reprogrammed it to provide up to 201 instead of 400.

What does Ryzen Master show when you enable the Asus Fmax option and choose a boost override of 400?

Recently I used Ryzen Master manual overclocking to set cores 1, 3 and 7 of CCD0 to 5GHz and the rest at 800 with CCD1 all at 800.

When running CB23 single core I haven't seen TDC go above 30A so I decided to use the max voltage of 1.51875v I could set in Ryzen Master.

It successfully runs the CB23 single core test and for the first run I manually configured the process affinity to core 3 to maximise the effective clock and it only scored 1539 whereas I was expecting at least 100 more points from it. I also tested with the affinity set to cores 1, 3 and 7 and the score was 1522 and the effective clocks for those cores was distributed like they were a single core running at 5GHz.

Evidently CB23 single isn't precisely a single core benchmark test. It's more of a single rendering thread test and Windows is seemingly randomly switching to any of the cores it believes are suitable.

A more precise test could be to disable AMD's c-states to force the active cores to always run at 5GHz but I haven't tried it as HWInfo64 shows the CCD0 cores I've set to 800MHz as being clocked at 4GHz so I presume the effective clocks without c-states would be five cores at 4GHz and three at 5GHz. The max current is uncapped when using manual overclocking which could result in CPU damage with a core voltage above ~1.275v according to what I've read.

Also Ryzen Master said the voltage can go higher if I was to enable LN2 mode but my Asus ITX board doesn't have that option, however, I managed to test it anyway. The max is 1.55v which I set manually using a SMU command but the system reboots when I run the benchmark suggesting a reset safety feature was activated rather than a limit of the CPU.

I investigated this type of overclocking as a proof of concept that it might be possible to programmatically switch to manual OC mode for all-core loads and then back into PBO mode and I was able to use all the necessary SMU commands for doing so.

I now think the CPU was rapidly overheating when the PC reset at 1.55v.

Evidence suggests the reset occurs because the CPU temperature increased so quickly that there isn't time to do the less critical CPU Temperature Warning on the next boot.

I ordered a brand new 5950X recently to replace the faulty one I have been experimenting with and I'll be sure to keep it's CPU core voltage in the safe range.
