HP PROLIANT ML350 G4P memory upgrade (4GB) problem

Hi all, I've removed 2 512MB ram modules (1GB total) and replaced with 2 2GB ram modules (4 GB total) on the same slots.
The installed memory is DDR2-400 ECC DDR2 SDRAM, (02GHP1658) HP certified for HP PROLIANT ML350 G4P ( server p/n 380173-421 ).
On boot BIOS recognize ONLY 2048MB (on slot #1) !! Why ? Must I BIOS configure to recognize up to 2GB ??
Thanks in advice.

ok, my PROLIANT is an 380173-xx1, but what means "DIMMs must be configured in identical pairs" ? I buyed two identical 2GB DIMMs and replaced two 512MB DIMMs.

Thankyou

hi,

you could try to update the firmware on the proliant.

Re: HP PROLIANT ML350 G4P memory upgrade (4GB) problem

I have recently had reason to purchase memory, and think I have figured it out. It says in the quick-specs you are not allowed more than 8 ranks in total.

NOTE: Online Spare Memory is not supported when using 2-rank DIMMs. A total of 8 ranks are supported on the HP ProLiant ML350 G4p, A maximum of 4, 2-rank DIMMs can be populated. If you plan to mix DIMM types, 2-rank DIMMs must be installed in the first bank, 1 rank DIMMs can then be installed in subsequent banks.

This is why the 2Gbyte modules are available in single-rank. If you use 6 single-rank modules (3 sets of 4 Gbytes) giving you 12 Gbytes, you have to use single-rank modules. http://h18000.www1.hp.com/products/quickspecs/12199_div/12199_div.HTML (click on the 'memory' heading at the top).

Hope this helps you!
