Memory Upgrade issues

I'm having some trouble upgrading my Proliant DL140 G3 from 8GB of RAM to 16GB of RAM.    I bought 8 identical (part #/speed..etc..) 2GB DDR2-667 PC2-5300 ECC FBDIMM.  I've installed all 8 chips into the 8 available memory slots.  However, when I boot up, only 8GB is scanned and reported.  When going into the BIOS, it also only reports 8GB of extended memory.

 

I have updated the BIOS to the latest and swapped the chips around, putting only 4 in at a time so that I know all of the memory chips work.  Based on the layout, the memory slots go from 1-8 (with slot 1 closest to the PCI slots).  It seems only slots 5-8 recognize the memory in them.  I ran the HP diagnostic CD and it claims slots 1-4 are not occuppied.

 

Doing some research and studying the motherboard layout, slots 1-4 are associated with branch 0 and slots 5-8 are for branch 1.    I'm running two Quad core Xeon  E5345 running at 2.33 Ghz

 

BIOS settings under Advanced Chipset Control are using the default settings:

 

4GB PCI Hole Granularity: 256MB

Memory Branch Mode: Interleave

Branch 0 Rank Interleave: 4:1

Branch 0 Rank Sparing: Disabled

Branch 1 Rank Interleave: 4:1

Branch 1 Rank Sparing: Disabled

Enhanced x8 Detection: Enabled

 

Am I doing anything wrong? Could there be an issue with the motherboard?

 

Thanks,

 

Dennis

Re: Memory Upgrade issues

this sounds like the wrong type of FB-DIMM. there are two types. One will do this, one will not.

Stick to HP (used or new or RENEW)!!

In the specification I see two 2GB memory part  numbers (461828-B21 (Low profile) and 397413-B21). What is your?

Re: Memory Upgrade issues

I thought I did get HP memory.. Actually, now that I look at the site again, it says HP certified memory.  Guess I made a false assumption that would work?  Here's the site I used:

The chips I bought were these.  I thought they were to spec?
