Is EPYC 7742 ES 2S1404 a good choice?

[maxermaxer]

I have seen some EPYC 7742 CPUs with such model. Under the AMD logo on the CPU there is a text string: 2S1404E2VJUG5, the second line is BB then the third line is ES. Seller's note says it is 64 cores 128 threads. After OC it can go up to 3Ghz. It can run stably at 2.4Ghz.

In HWINFO OPN field it shows: 2S1404E2VJUG5_20/14_N.

How is this different from AMD EPYC 7742 64-Core 100-000000053-04?

Thanks!

The -04 are two steppings newer (identical to retail) and generally clock higher. I'd avoid anything older than a ZS, from the Rome overclocking thread it would appear that the 2S are hit-or-miss with regards to overclocking and the 1S don't boot on anything.

Thank you Bayleyw, that's very helpful. I have studied another thread talking about the overclocking of EPYC. Between ZS series and -04 series it is fair to say the success rate of overclocking 04 is higher than ZS?

My main purpose is to use the rig to render 3D image (such as Corona).
