Memory channel configuration for a r720XD
I currently have a r710 and have purchased a r720XD to replace it. (Wanted more storage and CPU power). I am wondering if I can reuse my RAM from the r710 and transfer it over the r720XD. The system isn't here yet, But I want to know if I'll need to buy replacement RAM to go with it.
Current RAM installed in the r710 is 18X 8GB DIMS (Part number: H132M).
1) Following these ram guidelines I'm assuming that the way the system works, I will only be able to utilize 16 of the dims, installing them into (A1 A2 A3 A4/B1 B2 B3 B4 / A5 A6 A7 A8 / B5 B6 B7 B8) Giving me 128 GB of ram total. Is this a valid RAM configuration?
2) Is it possible to add the remaining 2 dims in slots A9 and B9 without populating the remaining slots with more of the same RAM? Would I use different slots to put the RAM on different channels, or this simply not a valid configuration?
2B) If just populating 2 of the slots with extra ram is not possible, Can I just buy more the same RAM and populate all the rest of the slots? Would that be a valid configuration?
2x Intel Xeon E5-2680V2 will be installed in the r720XD.
If a moderator wants the service tag of the r710 to check the memory configuration, let me know. It's using the original DIMS.
Thanks for your time.

Thank you for letting me know about the part number, but they too don't show as supported in the R720XD.
Sorry for having to be the bearer of bad news.

Dkahn222,
Unfortunately I don't see that dimm (G871M) as being compatible in the R720XD. To answer your question though, with 16 8GB dimms installed then A1, A2, A3, A4, A5, A6, A7, A8 / B1, B2, B3, B4, B5, B6, B7, B8 is the correct and valid configuration. Since the dimms are not supported in the R720XD though, then the other 2 questions are not going to be applicable.
If you like you can private message me the svc tag and I will verify the hardware as well?
Hope this helps.

Sent you a PM with the service tag.
Thanks
