Problem with 2950 RAM upgrade
I have a 2950 that had 4 x 1 GB of RAM. I bought 4 x 4 GB of new memory (Certified). I have updated BIOS, chipset, ESM and PERC. I removed the old memory and put the new 4 GB modules in the server. When I try to boot the computer, fans spin up loudly, but no display activity and no drive activity. The LCD on the server bezel does not display any error message, just reads PowerEdge 2900. I had the RAM replaced, but still the same problem. I have confirmed that the memory is DDR2 PC2-5300 FB 2R 667Mhz memory @ 4GB per module.
I am not sure what to try next. Any suggestions?
Thanks

Page 126, if you haven't found it already:

Just move the jumper over to CLR, power on and boot to BIOS (if present); power off, return jumper, and boot again. This will clear the list of BIOS hardware, forcing the BIOS to rebuild it ... if this list is corrupt, then it could have a hard time adjusting to the new DIMM's.

It doesn't "sound" like there should be a problem.
You might try clearing the NVRAM using the jumpers on the motherboard. Do the old DIMM's work when put back in? Do the DIMM's work individually in the first slot (cycle through to test that each is good)?

Yes, the server boots just fine when I put the old RAM in. I will try cycling through the RAM in slot 0 one stick at a time to see what happens. I will look for instructions on clearing the NVRAM using the jumpers on the motherboard. Thanks for the suggestions.

Awesome! Thank you very much. Cleared the BIOS as suggested and the server came up and recognized the new RAM. Thanks.
