Hi [NAME],   Unfortunately the processor has reach the maximum capacity of memory support. You may need to look into upgrading to E5-2697v2 which can support up to 768 GB per processor. Have 2 processor on each memory channels, then it will support to 1536 GB.    DPN# 2GVTM   [URL]
Hey y'all, Was looking into upgrading the RAM in my R620 and having a bit of difficulty determining the supported memory configurations using dual Intel Xeon E5-2640 processors. Based on the owners manual revision 5.0, I should be able to support up to 1.5TB via LRDIMMs - but based on Intel's specs for my processor, each processor only supports 384GB & iDRAC reports a max of 1.5TB. Not sure if this is something that was later enabled via a firmware update (since the original spec sheet does show a max of 768GB), or just a miss in the documentation. I'd appreciate any insight into the actual supported memory configurations and if I'd be able to run 64GB LRDIMMs with my processor. Thanks! Alex
