Regarding the CPU-Z screenshots below, is the current RAM actually a bottle neck on the system (not allowing it to achieve the rated/max FSB speed)?
If I were to replace the existing units with 1333/1600 MHz DDR2 RAM would there be a significant increase in overall speed (for non-HDD intensive tasks - ie. image manipulation in GIMP)?
"FSB:DRAM = 1:1" - I guessing the system has automatically lowered the Bus Speed based on the spec of the RAM.
The machine is pretty snappy at present, even with the (presumably) slow RAM.
