DL380 G4 Memory Problem

[Simon McLeod]

Hi,

I have 2 dl308 G4 servers that had 6x1GB ram modules installed. I have recently replaced these with 6x2GB modules to double the ram capacity.

Both machines will not recognise the additional ram - they detect 6x1GB modules when they actually have 2GB modules installed. Both servers are running latest firmware.

Anyone know what may cause this?

Please let us know:
What is the Operating System ?
Is 12 GB detected during POST/BIOS ?

i am running esx 3.5
it is not detected during POST/BIOS

Can you try installing 2*2GB in two slots, i.e minimum RAM
This server should support 12GB of RAM â 400MHz, PC2-3200, DDR2, SDRAM DIMM memoryâ
If the 2GB RAM is from HP, can you provide the part number?
Also what is the BIOS version installed.
When 12GB is installed will server give any Beep, does it complete POST and BOOT.

i have tried all combinations - it only seems to detect 1GB no matter which way I do it.

it completed post and boot and operates normally, just with reduced ram

the ram is kingston as follows:
Description: 4GB Single Rank Kit
Mfgr's System P/N's: 343057-B21 (HP/Compaq)
Form Factor: Memory Module
Pieces/Unit: 2 (Two 2GB modules, totaling 4GB)

[SumanBlr]

I checked the part number.

Please call HP Technical Support to get all the 2GB Memory replaced.

If you have bought this memory from a Vendor then contact them to get replacement.

It seems like it's an issue with new DIMM Modules.

Thankyou.

Hi there,

have a look here:

http://h18004.www1.hp.com/products/quickspecs/12028_div/12028_div.html

the problem is that for some reason you need to have dual ranked modules in certain slots and single ranked in the other. As far as I know you need two dual ranked modules in BANK A and in B&C you need single ranked.

Hope that helps.

this table on that page says you can have single ranked in all 3 slots
