Answer 2

I use Corsair in my builds. Bought lots and lots of it and never got a bad stick. I use Corsair Value Select for my regular builds and Corsair XMS in my
performance/gaming/overclocking rigs. Lifetime guarantee and compatible with just about everything. The Value Select comes in 2.5 and 3 CAS latency. If you're just adding to present memory and have 2.5 latency up the 2.5 will work althou it will run at the latency of the slowest ram in your system. Here's the Value Select 3200:

If youre using all new ram you may want to load it up with CAS latency 2 then:

All good brands. Don't get the expensive CAS 2 if youre gonna add it to slower ram because it would be a waste of money. Another thing to look for is the voltages the sticks run at as some run at higher voltages that you may not be able to adjust to in your bios. Also, if you're adding it to your present ram you don't want to put a high voltage stick in with a low voltage stick. Try to match the voltages if you can. They don't to be an exact match, just close.
