ProLiant BL460c Gen9 (727021-B21) - Wide Heatsinks

[sgunelius]

We have a ProLiant BL460c Gen9 (727021-B21), that we’d like to upgrade to 1TB of memory and it currently has 512GB (8x64GB LRDIMMs), so that would mean adding another 8x64GB.  This server has (2) Intel Xeon E5-2667 v3 (3.20 GHz/8-core) processors installed and we discovered they’re equipped with wide heatsinks that block DIMM slots 4 & 5 on either processor.

I assumed we’d only see the wide heatsink on higher core-count processors, but according to document below, it is required for the E5-2667 v3 as well.

Can we replace the wide heatsinks with the standard heatsinks for the BL460c Gen9 (Spare Part 777687-001)?  If someone has done this, were there any issues with heat dispersion?  Thank you.

Answered my own question and my only option is to replace the existing 3.20GHz/8-core/135W processors with an "equivalent" 2.6GHz/8-core/90W processor that uses standard heatsinks, so DIMM slots 4 & 5 are accessible.  64GB LRDIMMs are the largest HPE made for the E5-2600 v3 family, so maximum is 1TB (16x64GB).  If I'd been using the v4 processors, I could've employed the 128GB LRDIMMs, but I've got v3 processors & memory.

Based on HPE ProLiant BL460c Gen9 Server Blade QuickSpecs, DIMM slots 4 and 5 are not accessible when the E5-2699 v4, E5-2697 v4, E52697A v4, E5-2667 v4, E5-2643 v4, E5-2637 v4, E5-2699 v3, the E5-2697 v3, the E52643 v3, the E5-2637 v3, or the E5-2667 v3 is used. In a 2 processor configuration, there are twelve (12) total available DIMM slots.

Please refer HPE ProLiant BL460c Gen9 Server Blade QuickSpecs (page number 16 - 17) to check supported processor to use all DIMM's slots.
