hi,
I have some spare 8 GB (2x8) DDR3 RAM @ 2100 Mhz, so i want to install it in a pre-assebled ACER aspire m (PC), i7 @ 3,4 Ghz, 4GB RAM DDR3, bla bla.
will the computer handle 2100 Mhz?
thanks

RAM speed = Bus Speed x RAM Multiplier. The RAM Multiplier is by default on Auto. So long as you're above that minimum speed, you're good. Considering branded PCs have 1600mhz or 1333mhz RAM in them, you're likely to be good, so long as you're matching a DDR3 replacement with a DDR3 stock.

If the PC doesn't support 2100mhz, it'll automatically lower the speed.

RAM does not "run" at any speed on its own. It is sold at the fastest speed it is guaranteed that it will work- if you set it to that speed in the BIOS (it will always run at slower speeds no problem). All PCs have a default speed they run memory at. With DDR3, that default speed is usually 1333 or 1600mhz. So you want to install memory that is at the very least capable of running the default speed your PC runs memory. So in short, 2100mhz memory will work in your PC, and if you are able to do it, (doubtful with a prebuild) you can overclock it all the way up to 2100mhz.
