Finally: Overclocking EPYC Rome ES

[nineyou]

Does anyone know that Tyan S8030 supports engineering samples? Can it be overclocked?

ES or QS chip?

• If ES (ZS/2S), it all depends on the AGESA version more-or-less, see 1st post (hint: Agesa < 1.0.0.3)
• If QS (retail SKU ends with -04) should work with any board that supports 7002 series Epycs.

Yes, but the oldest BIOS version Agesa I can find on Tyan official website is 1.0.0.6, so I'm not sure whether this motherboard can be overclocked

mainboards that came with rome support generaly don't have old AGESA, if there is no naples revision the old BIOS can get from you are out of luck.
only QS then, depends on the VRM power stages.

Thank you for your reply

Off topic but I'm wondering if anyone has taken a shot at overclocking the Epyc milan ES/QS. There are a few Milan QS for sale in ebay right now.

It's not only an overclocking issue, but if you try an ES chip in a board with BIOS with AGESA > 1.0.0.3 the CPU will not even boot/post.

You need an ES or possibly an QS chip

Hi all,
I started using EPYC for my workstation. I saw this thread and was wondering what some of my options may be. I have an H11SSL-I and a 7302p. Are there any 16 core QS part numbers I can purchase? Basically looking for an alternate (cheaper) upgrade path vs buying a 7F52. My 7302p stays pretty much locked at 3.3GHz but I'd like to get my single core speed as fast as I can.

Just simply couldn't afford Threadripper Pro and I got into this build sub $500 + RAM (which would have cost the same anyway)

Smallest QS is the 32-core which is around $800, but proceed with caution: we're pretty data deficient for running the 32-core QS at high clocks and voltages for extended periods of time and its unclear if they'll degrade.

I have lots of hours of high duty cycle run time at ~3.4-3.5 GHz on a 32 core QS (-04)

Actually It's now my smallest machine and I'm debating liquidating it, I should have bought a pair but I tiptoed in.

Pair of 100-000000054-04 on H11DSi-NT here. I can run these chips at 3.5 GHz all core, but I needed to mount a fan over the VRMs or these would overheat. The cpus themselves are water cooled with a custom loop.

but I needed to mount a fan over the VRMs or these would overheat

note the VRM power-stages are soldered on the PCB and heaten up the CHOKEs, the CHOKEs are getting hot too.
from that point of view this heatsink typesare not very smart done.

Linux tools can be modified, however I'm working on a better detection, since Epyc and Desktop Threadripper 3000 series (Castle Peak) share the same basic cpuid, so another more complicated detection mechanism should be implemented - at least socket type detection is needed.

If you want, you can try the modified code, however for now it works on Epyc or on TR - not on both at the same time, since command IDs are different.
Attached is the modified version of my Zenstates-Linux fork: irusanov/ZenStates-Linux

It had been tested on a ES Epyc and it worked, but this version is unofficial until I sort out the cpu detection. Ofcourse, as always, everyone is free to contribute.

You can first try to set a different frequency and if it works, proceed following the guide and mess with rest of the things. For the test, please use the CLI, then you can use the GUI as well.

sudo ./zenstates.py --no-gui --oc-frequency=2000

Frequency works in 25MHz steps.
Be extremely careful with voltage. Make sure you have something to monitor it with - preferably a multimeter to check the actual voltage. Zenmonitor seems to be the best currently available on Linux, but I'm not sure if it displays correct info on Epyc: ocerman/zenmonitor

How to set core voltage?
