[SOLVED] RAM Upgrade

1043 Views 5 Replies 2 Participants Last post by  Tyree
Hey guys

I've upgraded my Mums computer memory from 256MB to 1GB. I ran CPU-Z and installed the correct PC-133 RAM, double checked with Crucial to make sure the Motherboard could handle two 512MB sticks in both slots, but for some reason the computer is only recognising half the RAM. Tried swapping the RAM around making sure both sticks are correctly inserted and working, but its definitely only registering 256MB on each module. Its an old computer, but at a bit of a loss. Has anyone any ideas?
CPU-Z is detecting 1024MB of RAM, 512MB in each slot, but the BIOS and system are only reading 512MB.

Re: RAM Upgrade

Assuming the PC is OEM, Brand & Model Number of the PC?
Where are you seeing it's only showing two sticks of 256?
Re: RAM Upgrade

Its quite old at least 10 years, running a Intel Celeron CPU (Tualatin). I cant remember any more details off the top of my head.
The system information in system tools is showing 504MB of memory, even though CPU-Z confirms 1024MB (512MB in each slot). The BIOS and Boot also shows only 512MB.
Through a process of elimination I've determined that both modules work, and so do both slots. When only one module is inserted only 256MB shows, so I'm assuming only half of each RAM stick is being recognised.
Crucial's scanning tool on their website confirmed that each slot can handle 512MB of PC-133 SDRAM.
Re: RAM Upgrade

What brand of RAM did you use? Crucial is generally very compatible with OEM PC's. Knowing the exact Model Number of the PC might prove helpful.
Re: RAM Upgrade

I've since replaced the RAM with lower density modules. It seems to be working properly now. Thanks for the help
