Hi all.

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!

PS
Forgot to say that even this little extra memory seems to boost the system. Some demanding programs seem to run more smoothly now.

Try to install the new ones on slots 2 and 4.

agreed. Sounds like your mobo might be trying to use dual channel when it can't (?).

Thanks for your answers. I tried that, but it didn't work
It didn't recognize either of them, just the 512MB existing one. It seems at this point as if the only slots recognized are 1 & 3. I wonder if it means they have to be paired or something (1 & 3, 2 & 4)

Here's the results of the scan from crucial.com, if it offers any extra info about my system. Dual channel is possible, according to it.

Any other ideas?

put the 256 sticks in 1 and 3 and see what it does? Then put the 512 in slot 2?is dual channel turned on in BIOS? may have to disable it?

Hi again.. I was out for the weekend

I tried this and again, it recognizes the ones that are paired in 1 & 3. I think I'll have to get another memory, so that I have 2 pairs. I'll keep you posted.


Thanks for your efforts

Here's an update, if some1 is facing the same troubles..

I got another 512MB stick. Having the original in #1, I placed the new one in #3. Booted OK, system recognized both properly, as 512MB each.

Then I tried to place the two 256MB ones in #2 and #4. Guess what? System reports 4 sticks, 256MB each!!

Any suggestions? Or do I just leave the 2x512 and feel thankful? ;)
