Memory not being sensed
I have two rp7420 server with once cell on each and having 12GBs of RAM (12 * 1024). We tried to upgrade it to 20GB by adding 4 more 2GB modules on both. It sensed only 16Gb even after trying different modes of RAM filling in cell. I am giving you the output of each server as below. Could you please suggest on this.
On serverA

Re: Memory not being sensed
it may be 'HP' memory but what is the part number on the dimms? is it the right memory for the system?
do you get any warnings at pdc about memory been deconfigured? or mismatched?
it only takes one dimm out of a pair to disable the bank.
the memory kits are quads as well, 4 dimms to one kit. so server A is configured wrongly to work anyway.
On each cell board, Memory Quads must be installed in the following order:
1st (0A, 0B, 1A, 1B), 2nd (2A, 2B, 3A, 3B), 3rd (4A, 4B, 5A, 5B), 4th (6A, 6B, 7A, 7B)
