The issue you described and based on the troubleshooting that you have performed already seems to be related to be memory slot itself on the board.
You have already tested different memory modules on same slot.
Could you please let me know if you have tried different memory slots?
Besides that how many processors are installed on this board and which model?
According to the technical product specification document https://www.intel.com/content/dam/support/us/en/documents/server-products/server-boards/S2600CW_TPS_Rev2_4.pdf.pdf
the error 0xE8 is for “No usable memory installed” which could be caused by different reasons. Refer to page 31 of above document.
Will be looking forward for you reply
Thank you for your reply.
The memory slot seems to be OK. The system normally boots with Kingston 32GB RDIMM modules.
I have tried six different SKhynix HMAA8GL7MMR4N-UH 64GB LRDIMM modules - each boot attempt has ended with an error. Moving memory to the next blue slot did not help either.
Right now, there is only one xeon v4 processor installed. I propably could switch to xeon v3, but not sure if this would help.
Today, I've updated system firmware to the latest available - unfortunately there is no change.
The seller claims that memory should be OK, but I'm not sure if something else could generate such a problem.
Does LRDIMM require any additional configurations?
Could you try to follow the memory population rules from page 26 from same document
It’s possible that your RAM error could be caused because of only one processor installed.
