Compatibility check for RAM and CPU in a a fully built HL15

General
1

Hi- I have some RAM and a processor that I’d like to repurpose, rather than upgrading later.

I’d order the fully built HL15, with the X11SPH-nCTPF motherboard.

The processors that I have are Intel(R) Xeon(R) Platinum 8170 CPU @ 2.10GHz, and the ram is Hynix HMAA8GL7MMR4N-UH DIMM DDR4 Synchronous 2400 MHz, which Memory.net shows as LRDIMMs.

It seems like they should work, as the docs state 81xx and that the 2400 speed ram as well. It will be a little slower than the 82xx series (2400MHz ram vs 2933MHz), but for the price (zero for the processor and RAM) I think that it’s worth the slight drop.

If I can get confirmation that it should work, I’ll probably order two HL15s… (I have 2xCPU and 12x64gb sticks :wink: )

I can’t confirm that CPU and RAM will work, but I agree it seems like they would.

You can’t order a “fully built” system from the configurator without a CPU or RAM. You would either have to;

a) work out a special arrangement with sales
b) purchase the lowest spec Bronze 3204/16 GB RAN version and do the upgrade yourself.
c) purchase the chassis. backplane & psu version and acquire two X11SPH’s yourself.

Note that the heat sink for the Bronze 3204 might be insufficient for the Platinum 8170. The 3204 is an 85W TDP part vs 165W TDP for the 8170. You may need to also provide more robust cooling for your CPUs.

Oh, I was planning for option B. For at least one of them it would enable me to migrate what’s on the Dell box that I’d be scrapping for this.

With regard to the cooler- the HL15 specs page says it’s a Dynatron B8 2U which is rated to up to 205w.

If that’s what ships with the bronze I think that I should be OK (?)

Worst case, maybe I’ll order one to start and verify.

Yes. Sorry, I don’t have the full build and wasn’t aware they had specified the heat sink on the specs page. I thought they might use something different for the lower end and higher end CPUs. I did say might. You should be fine.

It’s not the same model but I’m running some SK Hynix memory in my HL15 without any issues. It’s dual rank memory instead of the quad rank but I don’t think that should matter. I have to imagine that it’ll be fine. Plus you said it won’t cost you anything so, worst case, you have to go RAM shopping after giving it a try.

Oh, that’s a very interesting difference.

the memory configuration guide shows that for the first-gen CPU that I’m talking about is QR4

They’re only free if they work :slight_smile: otherwise they’ll stay in the server they’re currently in…

@rymandle05 I totally missed the context of your comment! I thought that you were saying mine was the dual rank vs quad. If yours works then mine should. It’s exactly in spec as a 64GB LRDIMM QRx4!

Thanks so much
