I also decided to reinstall my 2 Gb geil modules which I forgot to mention. The new cooler Im getting wont fit with anything other than low profile ram, I dont even need more than 12 Gb, and 1800 Mhz cas 7 is a lot better than 1600 Mhz cas 9 for gaming.

I already tried with just 3 modules and couldnt get them stable at 2000 Mhz, but that doesnt really matter when they do 1600 6-7-6, or 1800 7-8-7.

4 Gb modules will never do that, and there are no better low profile 2 Gb modules available than these geil ultra series ones.
