Hello,
We would like to upgrade our Z640 machine to 256 GB of RAM. Our machine has a pair of Xeon E5-2690 v3 CPUs, so we plan on purchasing eight 32 GB modules.
Reading the Quickspecs page 20, it says that only load reduced RAM modules (LRDIMMs) are supported for 32 GBs.
However, when I searched for compatible modules at some makers websites (e.g. Kingston), they showed both regular 32 GB DIMMs and the load reduced 32 GB DIMMs as being compatible with this workstation.
If possible, I would prefer purchasing the regular ones, because they are cheaper. However, I'm worried about compatibility as noted in the HP quickspecs.
So, could anyone provide me some information on the actual compatibility of regular 32 GB DIMMs?
