Ok , So my pc is a little over 4 years old and it came with a Motherboard which supports 1333 Ram only and lately i've been having problems with one of the 2 GB sticks in it. ( total of 4 ) ,Computer slows down and freezes alot. And i cant find any good 1333 Mhz ram that is good. Just a bunch of super generic ones. But there are some Hyper X and corsair 1600 Mhz ram available right down the street. Buying a new motherboard and all are out of the question right now since im tight on budget, So what would happen if i put take out the 1333 stick(s) and put in a 1600 Mhz 8gb kit? Am i going to run into some problems

CL stands for Cas Latency, it influences RAM speed. http://en.wikipedia.org/wiki/Ram_latency

Setting your RAM up for 1333MHz CL9 is very easy, because it's the default setting for DDR3 motherboards. So you don't have to do anything, just plug it in and go.
If you want it to run at 1600MHz you'd have to change the settings, even with RAM that's rated for that speed (usually through an XMP profile, very easy). But if your motherboard can't handle that speed your system might become unstable.

But if i run it in 1333Mhz cl9 settings there will be no system being unstable right?
