Title: RAM issues ??
Post by: MICMAN888 on November 18, 2007, 12:34:40 PM

Hi Y'all
I was installing new RAM for my 2nd PC which is for the kids but once installed it only registers a little under half of what it actually is.
The Mobo is a M7VIG 400/KM266 PRO with a AMD 1.8GHz Duron processor , I am trying to install 2x 1024 GB of RAM but only shows 960 MB so has anyone came across this problem and know how to fix....

                    many thanx in advance

You sure, you bought right type of RAM?

2 x 184-pin DDR DIMM
Maximum 2.0 GB

yeah I'm sure it's the right RAM "1GB PC3200 DDR 400MHz 184 pins" is what is printed on the sticker and it has 16x64MB

And does it have onboard video? And are both chips snugly inserted? Are they identical?

You may want to download and run Memtest and check each stick by itself and then both together for an hour or so each. (www.memtest86.com)

My bro-in-law had the modules in his PC and working fine last night and only passed the modules onto myself coz he upgraded his to some kind of crucial RAM that was ridiculously priced at over a hundred quid each.
I forgot to mention that i previously had 768MB installed 1x 512MB and 1x256Mb both DDR 400 and PC3200 and PC2100 modules and it was working fine and reinstalling these they do register what they are supposed to be and i have tried the new 1GB's of ram seperately and they show as 480MB each

OK, so now we are looking at a compatibility issue it seeems. Download and run Everest Home, make a report and post it here. THere are two sections relating to memory. Include all of the report to BELOW the second memory about RAM. It may take two posts to get it all, but down to the "SPD" section, right before "Chipset".

We need to see that both chips are recognized and the characteristics of them.  ;)

Possibly low-density versus high-density memory chip issue.  For what it's worth:

Less common, but sometimes a problem, with different density chips. If your MB is so equipped, use slots 1-3-2-4 instead of 1-2-3-4.
