Any News on LRDIMM support (see my latest post above) ?

Tugm4470's H11SSL-F Version 2.0 + AMD EPYC 7302P+/7371 is around 500 EUR but I wonder if there are better CPUs in the Zen2 (or Zen3) Range that aren't too much more Expensive than that 16Core/32Thread one.
My friend, currently the most cost-effective CPUs for Zen2 are AMD EPYC 7402, 7532, and 7K62

It also depends if LRDIMM can be used. I cannot add yet another 500 EUR or so when I already have this RAM.

The Manual says it should (with Zen1 though), with Zen2 the Manual looks very weird about LRDIMM Support.

It can still be used. You can send me your memory model for me to check
For now I have the following Types, all LRDIMM DDR4 ECC, but all relatively slow (max is 2666 MHz, some are 2400MHz only):
- Micron MTA72ASS8G72LZ-2G3B2PI (64GB 2400 MHz)
- SK Hynix HMAA8GL7AMR4N-VK T3 AC (64GB 2666 MHz)
- Samsung M386A4K40BB0-CRC5Q (32GB 2400MHz)

By the Way, did we have to do some "weird" VRM Heatsink Modification ? Not sure if it was on this Thread or something similar that stated that the VRM were overheating or something. Even more so with LRDIMM (these DIMMs can SIP +50% of Power compared to regular RDIMM Modules).

For me I just attached a small noctua fan to the heatsink of the VRM and that kept it under 70 degrees under load. But that's with 2 sockets 48 cores each. You may not need it for a single socket, less powerful CPU.

Your memory belongs to 64g 4DRX4, which should be usable. If it is 32g 4DRX4, it is not compatible with this series

So these should work with H11SSL-i with the Zen2 EPYC CPUs ?
- Micron MTA72ASS8G72LZ-2G3B2PI (64GB 2400 MHz) - should be 4Rx4
- SK Hynix HMAA8GL7AMR4N-VK T3 AC (64GB 2666 MHz) - should be 4Rx4

Weird that SMALLER Modules are not supported :oops:.

The Samsung M386A4K40BB0-CRC5Q (32GB 2400MHz) should be 2Rx4.

do you live in the parallel universe ?

Any Advantage of the 7D12 over the 7402 ? It's 32 Cores vs 24 Cores, but it's also 1.1GHz base Clock vs 2.8GHz base Clock :rolleyes: .

Looking at CPU benchmark seems like a worse performance although much lower Power ?

EDIT 1: this seems to indicate again Issues with SK Hynix Memory or Multiple DIMMs being used, due to the low TDP Rating -> https://forums.servethehome.com/ind...me-what-is-epyc-7d12.28654/page-2#post-373859

The CPUs are very fair priced, the motherboards and systems not. Usually after 5 years there is a big dump of older systems. But there barely exists anything for Epyc
Blame supermicro for releasing a very good MB (H12SSL-i) that every miner/crypto and LLM junkie buys and loves.

it supports mult-gen CPUs

Your question was about CPUs not motherboards.

My friend, the performance of AMD EPYC 7d12 is definitely lower than that of 7402, and 7d12 only has 4 channels

The advantage of 7d12 is that it has 32 cores, and currently 7532 is also a good choice. We lost $140000 on the 7402 and 7532 models

Would you have a reasonable Priced 32C EPYC Zen2 CPU you could create a bundle with a H11SSL-i Motherboard Rev. 2.0 ? I don't think I saw that Combo ....

(I'll have to hold off buying this EPYC System until next Month because my Budget for the Month is already gone)
