I'm using a Dell Dimension 5150 and just upgraded my RAM from 1GB to 3GB (January sales :P)
The current config goes like so:
Pair 1 - 2x1GB
Pair 2 - 2x512MB
All the system RAM is registering, but I'm not really seeing an increase in performance whatsoever (which I consider strange seeing as I just tripled RAM). Could anyone please suggest why there's possibly not much of an improvement?
Are the 2 1Gb sticks new, and the 2 512Mb ones from before the upgrade? You may not notice a speed boost because the 2 1Gb RAM sticks are having to run at the old 512Mb clock speed. Can you tell us what the clock speed (MHz) of the 512Mb sticks of RAM, and the 2 1Gb sticks of RAM. Your 'Lack of performance' may lie there.
Ok I will...
I would overclock my RAM, CPU, but Dell have disabled overclocking on their motherboards completely - I read somehwere this is as they are custom built for budget and can't supply the extra voltage etc. that overclocking requires.
