I have a DL380 G5 with system board 436526-001 that will not boot with 8 x 8GB RAM modules installed. These are genuine HP modules, part 495604-B21.
Symptoms: Fans start (take off speed!), screen remains blank and the server emits periodic beeps, all 8 DIMM LEDs are amber and red server health LED is lit.
These 8 x 8GB RAM modules work fine in another DL380 G5, and the problem server works fine with 8 x 4GB (32 GB total), so it's not the slots and it's not the RAM.
The BIOS version is Sept 2009
I am almost certain that this revision of system board supports 8GB modules (it supports quad-core E5450 CPUs that I've just dropped in), and I've got two other servers with this configuration working fine. Heck, I even put the 8 x 8GB modules into a DL380 G5 with the older system board 407749-001 and that boots fine with 64GB RAM reported and no problems.
Any suggestions as to what I can try to get the system to recognise 8GB modules? Does anyone know if the later system board (436526-001) definitely supports 8GB modules? This is in the UK, btw, not USA.
Thanks
