It makes no sense using a 64 bit OS unless you have more than 4Gb of ram. I’m behind the curve. Most of my boards only go to 4Gb, and even then they only actually see/use about 3Gb.
“It makes no sense using a 64 bit OS unless you have more than 4Gb”.
I agree. However, installing 4GB or more is standard for 64-bit OSs.
When the CPU runs in 64-bit mode it’s using more registers so its memory use is less. Code which is not memory restricted will run faster in 64-bit. I run large programs over a gig and digital photos all of which run and transfer much faster in 64-bit W7 vs. 32-bit XP.
Also, as more 64-bit programs come on line not having to format and install a 64-bit OS down the road comes into consideration.
