The Ripjaws X -1600- CL9, dressed in a beautiful red, immediately announce their pretensions ... it is fast, reliable, ...

We are in the presence of what is does best, no doubt, in the design memories strips.
Here is concrete, not aesthetic at a discount, and there is a perceived seriousness in the design.

In terms of strips, should be considered or the CAS (CAS LATENCY CHECK) that is roughly the reaction speed of the memory, the G Skill Ripjaws X PC 12800, 1600 Mhz, have a Latency Check or CL or CAS 9 (9-9-9-24). There has certe "CAS" faster, such as CL7 (CAS LATENCY CHECK 7) or also rare CL8 but already CL9 is fine, especially as the impact of the "CL" the sheer speed of a memory barrette is not really a concern, just a little more than having a CL7 versus a CL9.

With WINDOWS 7, and most motherboards, these two strips of 4 GB each, should be recognized, no problem.
(Simple Tip: Feel free to go check on the website of your motherboard manufacturer if they match, and if he has total compatibilitée it.

In summary; Barettes reliable, very robust, with the sublime aesthetics, delivered with a sticker LOGO beautiful Metallic and especially with heat sinks on top! not too big! (Something which is important when implementing on the motherboard - (do not interfere with the cooler) -.

GREAT PRODUCT !!!! , We still wonder how the competition is doing .. .. .. I highly recommend.

Just a basic tip: For good stability and control, barrettes for your memories and in the choice, be sure to check that the operating voltage (in volts), your memories strips (eg 1.5 volts) correspond to workings voltages supported by your motherboard.

Oh oh oh .... I have sought detailed Com during my various research briefs strips.
AHHH! ... We had to choose ... So I hope my Com. is sufficiently informative.
