Wondering if anyone else has ran across this or can help,
First off I purchased 10 Dell R7425 servers that were shipped with 7251 processors, long story short Dell shipped me the correct 7551 processors to put in.
After the dust settled I have 20ea 7251 sitting around, so I purchased a Supermicro H11SSL-i board but could never get it to post/provide a boot screen, thinking the board was the problem, I purchased a Supermicro H11SSL-C, same problem. Thinking that Supermicro may not support the 7251, I purchased an Asus RS500A-E9-RS4-U server, with no luck, it does the same thing. Through all this I have purchased the proper RAM each of the manufacturers listed on their "tested"memory lists.
On this post the author mentions that Dell Epyc CPU's may only work in Dell servers
