I've used several brands of memory cards and G Skill Ripjaw is right up there with the best of them. Affordable without all the weird colors and plastic molding, simple basic design and they work great. Leave the sticker on as it's a heat sink and helps remove excess heat from the memory chips. A small external auxiliary fan always helps for serious computer nuts, I never understood all the colors and flashing lights with computer components when the actions on the display screen.
