Subject: [SLE] SuSE 10.1 32bit and 4GB RAM, seen are 3.5GB
Hi,
I'm struggeling with the following:
My computer, a Dell Optiplex 620 has a Intel P4 XEON HT with 4x 1GB RAM. The kernel sees 3.5 GB only.
There is another trap for young players when installing large amount of RAM - and then discovering that you are not able to use it all (but this does not apply to this case being discussed here). When buying DDR for your motherboard, and which may also have dual-channel, make sure that you read the manual for the motherboard and see what is stated there about which DDR RAM may be used to be able to get the maximum amount of RAM. I didn't read my manual and bought 4 sticks of double-sided DDR only to find that I had to either install 2X double-sided dual-channel DDR and 2x single-sided DDR or 4x single-sided DDR in order to have all recognised and be able to use the total RAM installed. And they all had to be installed in certain configurations (slot-wise) for them to work. I had to remove 1x stick in order to get the computer to boot : -( . Cheers. This computer is environment-friendly and is running on OpenSuSE 10.1
