most CPU are
slow , you get what you pay for, just like slow cars are slow. T4200 core 2 is slow. and is OLD.
impacting performance doing what? PC can do 10,000- things, I can not guess what you do. or if online or offline slow.
NO OS told at all nor version, just the word OS. must we guess the topic?
old PCs are 32bit.
and 32bit OS
2 to the 32nd power is 4GIG. (do the math see?)_ calculators.
4GB of ram ,is 3.2GB to make that lame GPU chip use DDR aS VRAM
'as the GPU has no VRAM there, so STEALS it.
intel even uses that word in their data sheet (chipset g45)
chrome OS or Chrome browser ,what?
no version told
the sales add shows 3GB OF RAM That is round down from 3.2
and is 750MB below 4GB physical RAM seen in BIOS page 1.
the limits are Manifold
the old core2, CPU
the limits of GM45,. chip set.
see the limits on G45 (m = mobile) lost at intel now but is here
DDR2 only on your PC. 2 slots, 2x2 =4GB minus VRAM theft.
means 3.2GB;. some PC
some models then were sold with 1+2=3GB , to save costs.
2+2 is max, here, that is a hard cold fact of life G45.!!!
