u/AAAAAARRRRRR

I ordered an EPYC 9334 on eBay and got burned with a vendor locked engineering sample, so now I am looking to buy new. I already have a whole build with an RTX pro 6000, 256gb of DDR5 5600, and an H14SSL-N motherboard. I am hoping to run larger MoE models with split cpu gpu, and am wondering what kind of cpu I should choose.

Now that I am revisiting the choice knowing I have faster ram, I am thinking about 9005. I am loath to spend another $3000 for this build for a 9255, but the next step down seems to be a 9115 which is under $800 on Newegg. I could also go in between with the 9224 but that gives up on some memory speed. What is the play?

I ordered an EPYC 9334 on Ebay and just booted up to find an ES 9845. While it is pretty cool to own a 160-core CPU, I believe this is unsuitable for my needs as I don't actually need that many cores, it might be underclocked, and it probably won't work right. I would like to test it before I start the return because if it is good its probably worth more than what I ordered, right? What should I do to verify if it is good or not?

I need ideally 8x32gb RDIMM 4800mhz
I can do local near Boston or Seattle, or I can pay for shipping.
If you have something similar but not quite the same, please still reach out.
