Hello,
I am trying to add 16GB (2x8) of memory to a PowerEdge R710; however, I cannot get the system to work with the modules I have. The machine is currently configured with 8GB DIMMs in A1 and B1 (w/ two CPUs) and if I understand the guides correctly, I should be able to add the two new 8GB sticks in A2/B2.
If I try that configuration, I get a MEMBIST error that indicates A2/B2 have been disabled. I have also tried putting both of the old modules in A1 and A2 with the new modules in B1 and B2, in this case the server will not POST. I have also tried removing the old modules completely and putting the new modules in A1/B1 - this also results in no POST. I have tried other configurations as well, such as moving the new modules to A3/B3 in which case the BIOS tells me the configuration is not optimal, suggesting I move the DIMMs to A2/B2 but also gives the MEMBIST error and disables them. In any case, I do not see any MEMTEST failure messages like I've seen in some other posts on the subject.
I have updated the firmware to BIOS 6.4.0 along with all the latest iDRAC / USC / etc. firmware but that did not seem to change anything.
The new modules I am attempting to install are Hynix HMT31GR7BFR4C-G7. The CPUs are Xeon 5520s. Unless I'm missing something with the configuration, I suppose my question is; are these parts not compatible with the R710 or do I have faulty DIMMs?
Thanks for any help!
