Intel Xeon Memory Compatibility

[racker24]

Hi, 

 

well I will start with that I am new to server hardware and stuff. I just have some questions about intel xeon memory compatibility.

 

1. Does a 1st gen xeon scalable processor ( e.g. xeon gold 5115 ) will run with a 2nd gen memory ( e.g. HPE P03053-0A1 64GB 2Rx4 DDR4 2933 RDIMM ) at the processor's max speed? or will not be usable at all?

 

2. Does a 3rd gen xeon scalable processor run or be compatible with the same ram above that is listed at HPE memory matrix support page as a memory of a 2nd gen scalable processor. 

 

for context I got F***ed up by buying this memory HPE P03053-0A1 64GB 2Rx4 DDR4 to install on a server with an Intel Xeon Gold 5115 processor. And my reference for buying this memory?

the existing memory which has a sticker "Partsquick 64GB PC4-23400 2933 RDIMM" but when I looked on its specs inside the server's iLO. it registered as LRDIMM without a manufacturer or part no.

I trust the sticker label of the existing installed than its specs in iLO and look it up on HPE memory matrix support page. I do know about building desk computers, gaming or for other use. but servers are new to me.

as per my 2nd question we are looking to install it on a server with a 3rdgen xeon scalabale processor if its supported.

 

I hope anyone could help me here. 

you can see the image of what memory fooled me.
