Bad Memory Slot? (ProLiant DL385 G7)

[jah6q]

Hello, I received an old ProLiant DL385 G7 for a project and I've mostly restored it to working order except for the memory.

I have 8x 8GB Dual Rank HP-branded memory which I have confirmed all work. But on (one side) I've noticed that the RAM slots 4 and 7 will not accept memory (even verifiably working memory).

So after discovering this I've just arranged my memory as follows (which gives me a total of 48GB):

Processor 1: [1, 4, 7, 10]
Processor 2: [1, X, X, 10]

Where X is an empty slot that should be populated according to the rules.

My questions are:

 - Do I have bad memory slots?

 - What could cause this?

 - Can I fix this?

 - Is it something else?

Thanks!

- Do I have bad memory slots?
Ans:
If verified working memory is not working in the given slot , it indicates issue with slot, however , you may clear the NVRAM and allow the ROM to re-initialise the memory modules , if it fails then there is an issue with the slot.

- What could cause this?
Ans:
It could be general slot failure and/or damaged memory slot.
Bent Processor Pin might be one of the cause. Swap the Processor to check if the issue follows the processor.
[Note: utmost care should be taken during processor swap to prevent any damage to processor pins during activity.]

- Can I fix this?
Ans:
If the issue is with Slot , System Board replacement will fix it.

- Is it something else?
Ans:
All Memory module should be of same specification.[Recommended]
Look for bent processor pins
