Poweredge R510 CPU and Memory upgrade
I currently have an PowerEdge R510 with a single Xeon X5650 with four 8GB DIMMs. I would like to add another X5650 CPU and add two 16GB DIMMs. So in total, I will have (2) CPUs, (4) 8GB, and (2) 16GB for a total of 64GB.
I wanted to know if the configuration below will work.
CPU 1
- 16GB in slot A1
- 8GB in slot A2
- 8GB in slot A3
- slot A4 empty
CPU 2
- 16GB in slot B1
- 8GB in slot B2
- 8GB in slot B3
- slot B4 empty
Thank you.

Hi,
The memory channels have to match. With channel 1 on each processor having 16GB and channels 2 and 3 only having 8 they don’t match. You can mix sizes only with channel 1 slots 1 and 4. So a config of A1 16GB A4 8GB B1 16GB B4 8GB would work. Page 117 http://downloads.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r510_owner%27s%20manual_en-us.pdf

The channels don’t match then, you probably need two more 16GB sticks and just fully replace the 8GB ones.

Thank you for the reply, Josh. Your suggestion would leave two 8GB sticks unused. Would the configuration below work?
CPU 1
CPU 2
I've read the memory section but I'm not confident in my understanding of it so I'm grateful for your help.
