i have a problem with adding memory to an IBM X346 Server (type 8840)
The server ran with 4*1GB dimm's from IBM (DDR2-400 ECC CL3)
i wanted to add 8 Gb (server specs say max 16gb so 4+8=12)
i upgraded the bios to latest version (rev17 dated november 2008)
I tried Kingston Valueram (4X KVR400D2D8R3/2G), and that didn't boot up.
(specs: 2GB PC2 - 3200 REG CL3 ECC 240-Pin DIMM
After i compared detailed specs, i saw i was trying Dual-Ranked memory, and thought that was the problem. So I tried another type that's single ranked: (4X KVR400D2E3/2G)
(specs: 2GB PC2 - 3200 CL3 ECC 240-Pin DIMM), still didn't boot up.
Can someone explain me what the problem is? Or is it possible that IBM has some kind of 'protection' system that doesn't allow cheap ram into their servers?
Thanks a lot!
