Question 1

How do I find the right parts for my Dell PowerEdge server?

Accepted Answer

Use the Dell service tag (7-character code on the front bezel or server chassis) to identify your exact model and configuration. You can also use our compatibility checker at /systems to see which parts fit your specific PowerEdge model.

Question 2

Can I mix different memory sizes in a Dell PowerEdge server?

Accepted Answer

Dell recommends identical DIMMs across all channels for optimal performance. You can mix sizes but will lose interleaving performance. Always match speed (MHz), rank, and voltage within each memory channel.

Question 3

What RAID controller does my Dell PowerEdge use?

Accepted Answer

Most Dell PowerEdge 14th Gen (R740, R640) use PERC H740P or H330. 15th Gen (R750, R650) use PERC H755 or H355. 16th Gen (R760, R660) use PERC 12. Check your server configuration for the exact model.
