ibm x346 server memory problem

Hello,

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!
Geoffrey.

The first ram didn't work because it went over the max allowed ranks(8 on this system) with the old ram installed. The new stuff isn't working because its non-registered and the system requires registered ecc memory. Here's what kingston shows will work in your system. http://www.ec.kingston.com/ecom/configurator_new/modelsinfo.asp?SysID=19833&mfr=IBM&model=eServer+xSeries+346+(8840&search_type=&root=us&LinkBack=http%3A%2F%2Fwww.kingston.com&Sys=19833-IBM-eServer+xSeries+346+(8840-xxx)&distributor=0&submit1=Search. Single rank 2Gb registered ecc dimms aren't cheap, Crucual has some thats cheaper than the kingston but it doesn't support chipkill http://www.crucial.com/store/listparts.aspx?model=e-server%20xSeries%20346%20(Type%208840).

thanks,

would it be possible to make it work with only the 4 bars of the first new memory? or is it more than two ranks per dimm?
in wich banks should they be places?

It's worth a shot, try it with only the 4 sticks of dual rank, this will max it out at 8 ranks.

i tried 4 , result no video, no beep-code
i tried 2, video, but hangs when it should count the memory.

in the logfiles of the RSAII adaptor it gives a 'firmware hang' and 'firmware error' message on those timestamps.

Could something be wrong with the server or is there a specific reason for the dual-rank not to boot?

Both crucial and kingston only guarantee 1 rank dimms for the system ,so it must be some sort of limitation of the memory controller.
