K7 Triton mobo - RAM upgrade not recognised

  PA28 19:40 17 Feb 07

I have the above motherboard (GA-7N400) with an Athlon 3200, 1gb (2 x 512mb) Kingston DDR400 RAM running on XP SP2.

I have bought two more identical sticks of the same Kingston 512mb RAM and have put them in the empty slots to give a total 2GB capacity. They aren't recognised at all by the system. The system is still working as reliably as ever, but only reports 1gb RAM in place. Any ideas please?

Have you tried running with the original memory removed and just the new memory installed to make sure that this doesn't have a problem?

If you run 4 sticks of memory in this motherboard. The first two sticks can be either double sided or single sided. The last two sticks of ram MUST be the same type,size and single sided ram.

Are the last two single sided?

I have two of the pro versions of this Board and confirm what ed-0 has said.

For 4 memory modules...
Channel A = DIMM 1+2, both Double or Single sided.

Channel B = DIMM 3+4, both Single sided only.

Ah. Single sided. All sticks are the same (Kingston KVR400X64C3A/512). I believe that these are double sided (can someone confirm please?). This may well be the root cause of the problem.

Would appear to be double sided
I.e. Chips on both sides

Many thanks. Chips going back.
