Problem with adding extra memory

zillur · 09-21-2015, 12:31 PM

Hi there,
I am a new user of a linux workstation: Intel® Xeon(R) CPU E5-2630 v3 @ 2.40GHz × 16
62.7 GiB

64-bit

I wanted to add some memory in the memory(16gm ddr4-2133 1.2v dr*4rdim) slot. But after adding them my machine doesn't start up. What should I do now?

What you should do is remove the new memory and reinstall the old memory to get your system back online.

The memory you add and where you add it is dependent on who made the system. You must use memory that is compatible with the system. Often you must install memory in pairs or other physically interleaved layouts before the system will recognize it. Again you'd have to find out who made your system (or mother board) to determines the specifications and memory layout scheme required.

Of course it could be that you simply got a bad DIMM if you have the right specifications. If so and you bought more than one DIMM you could try installing less than all the DIMMs to see if it works trading out one DIMM at a time (or in pairs if required) until you figure out which one was bad.

That last time I saw this the new DIMMs fit perfectly into the system (a Dell PowerEdge R410) but were not actually compatible with the system so it wouldn't boot until we returned them for the correct DIMMs for that system. That is to say the DIMMs weren't defective, they simply didn't match the specifications of the system we'd installed them in.

Thank you very much for your kind suggestions. How can I reinstall old memory?

how did you add the new memory?

As far as I can tell. Just remove the added/new memory sticks. You should reboot just fine.
My free Dell servers are picky on whether Full Buffered or Non Buffered memory sticks are inserted in the slots. Some like Full Buffered. Some Like Non Buffered.

If I wish to make them non bootable. I just need to put a Non Buffered stick in a Full Buffered stick box.

Ram is complicated that way.

I just added those memory in the blank slots.

Could you give us some details regarding your workstation:

What is your motherboard model?
How many memory sticks are currently installed?
Specifications of all the memory sticks (Including Memory Size, Clock Speed, etc.)

Did you try booting with just the new memory stick?

pan64 · 09-22-2015, 09:43 AM

so you can just remove them again, or remove the old ones...

zillur · 09-22-2015, 09:47 AM

I removed the new memory and the computer is running.

What about booting the computer with only the new memory in the slot?

zillur · 09-22-2015, 09:50 AM

How can I boot if the computer doesn't start.

I thought you started the computer with both Old and New Memory Sticks.

With new memory sticks my computer doesn't turn on. When I remove them it works fine.

Looks like you bought the wrong sticks then?

Even my Chromebook tells me what is compatible

Google should tell you what ram is comaptible as well as a little help from
