I upgrade the stock 8GB to 64GB of RAM in the HPE ProLiant ML30 Gen9 using 4 DIMMs (“Sticks”) of Kingston KVR21E15D8/16.

I upgraded to 64GB of RAM in my HPE ProLiant ML30 Gen9 using Kingston KVR21E15D8/16 from Newegg. The KVR21E15D8/16 was suggested by Schoondoggy on the forum thread RAM for ML30 Gen9.

Figure 12 – Temperatures appear well within range while system fan speed was a consistent 6% – BIOS set to Optimal Cooling (Note that the two 40mm fans in the Icy Dock ToughArmor MB994SP-4SB-1 were also running).


Figure 13 – HPE ProLiant ML30 Gen9 running with 64GB RAM and using 30.1 Watts. Everything seems to be working well – time to think about adding more drives and turn on Hyper-V!!
