I am planning to by some Dell refurbished PCs for window 7 migration
The configuration is DELL OptiPlex 760 SFF E7500 2.93 4GB 250GB
The supplier says that some PC have 4 x1Gb RAM stick and
some of them have 2x1GB & 1x 2GB RAM sticks.
If there is different size memory modules , will this cause any performance issue ( Clock speed)
Please suggest , is there anything I need to confirm form the supplier before I could buy
