Using a Windows 64 Bit Operating System

If you only have 4GB RAM in a Win7 64bit O/S, then its really reducing features because it needs to access more RAM to run 64 bit programs efficiently.
But the 32 bit programs will run at their peak.
You really should install the Maximum RAM in a New PC after you buy it with the Correct MHZ Speed and Type for it.
You have to match up the Correct DDR3 RAM with the Motherboard.
(Example: DDR3 1333MHZ or PC10600.)
Some PC's will access 16GB and some only 8GB, depending on what motherboard the manufacturer uses.
Which tells you if they really are giving you a PC that will work with Windows 7 maximum or its an economy model for general use.
Even higher end Motherboards can use 32GB or more, but are expensive.
Also some PC's have 2 rows for RAM chips and some have 4 rows.
If its a 2 row RAM slot then its easy to figure using 2 8GB RAM modules.
If its a 4 row RAM slot then you have to put 4 4GB RAM modules and they should be matched pairs Dual In Line to install correctly.
The rows will be 2 blue or 2 black and you want to put the same type in each color coded slot so it can be Dual In line
using slot 1&3 and 2&4 on some boards or on others its 1&2 and 3&4 spaced apart from each other.
Just look on the Motherboard at each slot and see the micro print next to it.
It will say DIMM1, DIMM2, DIMM3, DIMM4 on the Motherboard.
Look closely for it to follow its pattern to install correctly for the proper RAM.
It will make a dramatic difference when running newer 64 bit Programs on Win7.
