Slot 3

[Jim]

AOpen AX4GE-N motherboard. Has 3 RAM slots for plain old DDR. Bios auto
setting was driving original RAM @266MHz or PC2100, 512MB.

Went to crucial website, said motherboard would take PC3200, 400MHz. Bought
two 512MB modules, single sided. Installed both at slots 1 and 2. Bios
still ran RAM @266MHz. Saw both at 1GB total The only manual setting was
the same for speed. Looked at old RAM, its PC2700, double sided.

Tried the old RAM in slot 3, not recognized. Moved new RAM to slots 2 and
3, left out old RAM. PC only saw 512MB.

How can I use all 3 RAM slots on this motherboard?

Try just 1 new RAM in Slot 3 first to check if it's even working to
begin with

modules.

I checked at www.kingston.com for your motherboard.

According to that website, your motherboard has 3 slots that take
memory that runs at either 266 Mhz or 333 Mhz, NOT 400 Mhz. So they
are in conflict with what crucial said. I don't know who is right, but
one of them is wrong...

Also, Kingston says that you can use all 3 slots but only up to 2 GB
RAM, which is the limit for those motherboards. So it looks like they
provided the 3rd slot in case someone already had 2 x 512 MB dimms and
wanted to add another 1 GB.
