I can't say for sure whether or not memory will work that is not validated. I don't show a model or part number on that page to check if it is validated. I don't think the memory will work. There appears to be conflicting information posted on the memory. They list the memory as 5300P, but they also list it as registered/buffered memory. I'm fairly certain a memory module cannot be both P and R, but I could be mistaken. I think those are 5300R and not 5300P though. Thanks
so i have a poweredge 2970 ( ) without any ram and i have purchased some ecc fully buffered ram (link below ) however i have just read the manual and it specifies that it uses ecc registered ram (dk581) . will the ram that i have purchased work or will i have to buy some ecc registered ram instead?   link for the ram i purchased : [URL]
