Aj3293, You are having fault with one or both of new memory DIMMs. The easier option is to return the memory to the seller and order new one or try to isolate the faulty memory by using only CPU1 and one stick of memory at a time in dual in-line memory module (DIMM) slot A1. Let me know if you have any further questions.
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!
