Dell Precision 5820 - Max Ram

Question

Hello, I have a Dell Precision 5820 with an Intel Core i9 14 Core (i9-10940X) 3.30 GHz. I was under the impression that the max ram for this system was 256GB. I have installed 8 sticks of Micron MTA36ASF4G72PZ-2G6E1 902 32GB PC4-2666V RDIMM into the machine but it does not seem to like it. I get three beeps then two amber lights followed by 5 white lights. Which indicates that the ram is not supported.  I though that you could use ECC ram with the i9 processor.  I was wondering if someone could help me figure out if there is a setting that needs changed or if I am just SOL.  Thanks!

Try DDR4 UDIMM memory.  Core-X processor does not like ECC memory.  See compatible memory at Crucial  https://www.crucial.com/compatible-upgrade-for/dell/precision-5820-(intel-core-models)

@Chino de Oro​ It is possible to use 2 modules of 32gb (64gb) of the crucial PRO brand model CP32G4DFRA32A-M16FF ?
