Generic problem for all PC Desktops
Weird (?) RAM problems (screenshot included)
posted by Sunriser on Jul 17, 2008
My computer had 512MB of RAM (1x512) and today I added some more,
namely 2x256MB=512MB. The computer booted OK, but I checked and from
the two new sticks only one is recognized.
- BIOS says there's 512MB on slot 1 (the old one) and 256 on slot 3. There should've been also another 256 on #2.
- Windows Hardware info (from control panel) also gives 768MB (bit less actually, coz of shared graphics memory)
The CPU-Z program, however, mentions 1024MB in total, but still reports no memory in slot #2!!! I can't understand what's wrong..Here's a screenshot:
Both new memories are identical (at least I think so). I tried to swap them, or even install them on slots 3, 4 (bypassing slot #2), but still nothing.
Any suggestions? Thanks!

Thanks for your input.
Here's the results of a scan from crucial.com:
http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=A4F5129F31D926C3
The PC's maximum memory is 4GB
I've tried both memory chips, they both work OK when they're alone (with the original 512 that is). The slot combinations 1,2,3 - 1,3,4 give 768 MB and the combination 1,2,4 512MB. It seems s if the mobo recognizes only slots 1-3. I think the memory should be added in pairs (1&3 and 2&4)

Guruhi im wesley. you might be getting a clash with the two different types of memory, you see when you add more memory its always a good idea to put in the same memory and speed size as what you already have in because if you put lower memory and a slower speed in it actually will slow your pc down the 512 will run the same as your 256 card and can sometimes cause a problem. and if thats not the prob then the memory you put it might be faulty and damaged something on your board.

WizFirst of all, make sure the ram are identical, becuase having 3 different random access memory chips in the computer can cause problems. Also make sure the ram chip is sitting in there properly. Next you should check under start go to run and type in "dxdiag".See how much memory it reports the computer has. If it reports 700etc mb,, then the one memory chip might be faulty. Also, check with the system manufacturuer, and make sure you're not overclocking the computer. Overclocking is when you put too much memory in a computer and it doesnt recognize one of the chips. 700etc mb might be the maximum your computer can handle.
