Also note: As a test on my T5120. Just a heads-up, something to think about.Installed 8 matching 4GB "Samsung M395T5160QZ4-CE66 0819" dimms in DIMM D0 slots (32GB) and 8 matching 4GB "Samsung M395T5160QZ4-CE66 0816" dimms in DIMM D1 slots (32GB). For a total of 64GB with no errors. Debian 12 sees all 64GB and "show faulty" ilom cli doesn't report any memory error(s).
PS: Time for me to focus on IBM Power 8 and AIX stuff now :-) Best of luck Jeremy. Regards, Tony On 9/3/25 2:52 PM, Tony Rodriguez wrote:
Typically, I agree. However, Samsung dimms "Samsung M395T5160QZ4-CE66 0819" and "Samsung M395T5160QZ4-CE66 0816" both work on my end (without any errors), provided they are all the same type/revision and no mixing between them. I also installed sets of 8 or 16 (each dimm is 4GB and 1.8v.) .Agreed, best to avoid going into that rabbit hole mixing dimms capacities and types (especially on sparc hardware). Keep it simple principal :-)Regards, Tony On 9/3/25 1:34 PM, Dennis Clarke wrote:On 9/3/25 15:32, Jeremy Leonard wrote:Also, According to this doc: https://docs.oracle.com/cd/E19712-01/820-3318-14/820-3318-14.pdfThe general rules for these Sun/Oracle systems : 1) only use the correct supplier parts. That means Oracle. If you are buying used stuff then Sun is the supplier. 2) get all the memory at once. Never mix and match ever. Otherwise you go down a rat hole with no cheese.
