Hi,

Sorry about the slow response to your question on this forum.  Not many will response to workstations and especially those with "big iron" hardware.

Review page 7 in this manual.

Your PC has four (4) channel memory functionality but with the existing two dimms its not running in four channel mode.

I suggest that you buy the exact same two dimms from HP and populate the dimms (all four) in the first bank of each channel.  That should get all four channels operational.  You can download CPU-Z to verify the four channel operation once you get the PC up and running.

When populating the dimm slots use all the white dimm slots or all the black dimm slots. It shouldn't make a difference but if it does then go with the other color.  Just don't intermix the dimm in different colored dimm slots.

You might want to consider W10 as memory management is much better compared to W7.

BTW--Nice PC.:smileyhappy:  I had a similar motherboard with a X99 socket in a custom PC that I had built years back.  I ran with one dimm in one bank for each channel in order to get all four memory channels working.  You end up with terrific memory throughput.:smileytongue:
