I'm upgrading a Gateway P5-133 w/ 16mb of RAM to 64mb. I purchased two 32mb SDRAM 'cause the manual says that it doesn't support single 64mb. It has 2 DIMM slots so 2 sticks should be fine. But when I installed the memories, the system only detected 16mb, I checked the BIOS and it states that both memories are detected. I removed one of the memory and I found out that each one is being detected as 8mb (I know that they are 32mb 'cause I used them in a different machine and both worked fine as 32mb). One thing I noticed is that the old 16mb memory have 8 chips and the new 32mb (PNY memories) only have 4. If anybody had this experience before I'll really appreciate your help. I don't want to order memory direct from Gateway 'cause it cost too much.
