I recently upgraded my pc from 64MB to 192MB. I have a Supermicro P6SLA motherboard that had a 64MB DIMM module and I bought a 128MB DIMM. I moved the 64MB DIMM to the second slot and put the 128MB DIMM in the first slot. When I boot it usually shows “Checking NVRAM” and then it shows the RAM below it. It still shows “Checking NVRAM” but it does not show anything below it. I looked in the system applet and it shows that the RAM was recognized and I can tell that the performance of my pc has improved. Why would it not show anymore and does it make a difference?
