Memory Problem

We recently tried to update memory for a hp 512n 1.4 cereleon comp. The motherboard says the max is 512 so we up graded it to 512 however it is only reading 128 from both of the 256 slots. The best buy guy didnt know what to do nor did the hp guy. They though it was the bios but its been reset and updated. Any suggestions.

 

I am not a computer whiz - I can assure you, but just a thought from experience. Are you sure you installed the proper memory? I recently installed 256 memory in my Compaq computer and it read only 128 - the problem was that I had installed single sided memory - not double sided memory as is required for that particular computer. Be sure to go to a reliable memory configurator - or to the computer manufacturer and determine that you in fact have a compatible memory. Just a thought - maybe you have already addressed this - but I didn't - and I was getting similar results. Once I bought and installed the PROPER memory, it recognized the total amount installed.

 

I too am no expert..but make sure that you used the correct type of memory: pc 100/pc130.....ECC or non ECC...these things are important and an error could cause the incorrect reading

 

sounds like john burns is on the right track although usually that problem is caused by installing high density(double sided) memory in a board that doesnt support it....not the other way around.

what happens is that the board only reads one side..hence half the memory. I would head over to www.kingston.com or www.crucial.com and check their memory configurator for a suggestion.
