How come my computer is not recognizing my new RAM?

by on August 15, 2009

Q: I have recently brought some new ram for my computer but I can’t seem to get it to run. I did a scan of my computer and these are the results:

System Manufacturer: GBT___
System Model: NVDAACPI
Motherboard Manufacturer: Gigabyte Technology Co., Ltd.
Motherboard Model: M55S-S3

Your Computer Specifications

1024 MB DDR PC2-5300

Maximum Memory Capacity: 2097152 MB
Currently Installed Memory: 1024 MB
Available Memory Slots: 3
Total Memory Slots: 4
Dual Channel Support: N.A.
CPU Manufacturer: AuthenticAMD
CPU Family: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ Model 11, Stepping 2
CPU Speed: 2010 MHz

The new ram I am trying to install was listed on ebay as this:
2GB PC2-5300 667MHZ 667 5400 DDR2 DDR-2 RAM MEMORY 2G.

When I removed the 1gb ram that i have in currently and put in the new stick it loaded up to the boot screen that gives you the option of going into bios etc. but freezes up as soon as it lists my processor type. I cant use any of the key options available i.e del / f10.

Is this just because it isn’t compatible? Althought I would’ve thought if this was the case it wouldn’t have loaded up at all.

I am running Windows XP.

    The RAM might be defective. Check with your local computer repair shop, they should have a RAM tester that can confirm if the RAM is good or not.


    Hi Mark, Thanks for that. Have just got it back from the computer shop and they said it passed there memory test so was o.k. I decided to buy some ram off of them and have installed that no problem. Now when I put the 2gb stick in that i couldn’t get working earlier it loads right through tojust before where the windows splash screen should appear then reboots the system. Why would this be happening.


    Your motherboard might just not like that stick of RAM. Some systems are just picky with their RAM, and mixing and matching RAM sometimes runs into finicky problems like this.

    If you want to run some more extensive tests on that stick of RAM you can try running to test it, but we already know the stick doesn’t work with your system. I suggest just getting rid of it however you feel is appropriate.


    had a feeling that might be the case. Althought was obviously hoping there may have been a miracle fix for it :). Thanks for your help
