Corsair ram... adv. ?

Hi, just looking at some ram from corsair for my new pc, whats going to be the difference between these two, im planning on using my pc for development and some gaming etc it will have a C2D E6600.

Corsair 2GB DDR2 XMS2 Dominator PC2-6400C4 TwinX (2x1GB)

Corsair 2GB DDR2 XMS2-6400C5 TwinX (2x1GB)

and also what about this compared to the dominator ram :

GeIL 2GB (2x1GB) PC6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit (GX22GB6400UDC)

thanks

The C4 has tighter timings than the C5. Everything else being equal, the C4 ram will be a little more responsive. Also, the cas 4 latency gives you the ability to loosen up the timings a little and run a faster speed should you choose to OC.

so for me really.. not a serious OC'r, im not gonna see much difference

You should get a more responsive PC with C4 times compared to C5 times. (the preformance gains are often debateable and depends a lot on the applicaiton)

As for the low end dominators.... people will say stay away from them because they are not on micron ICs. But seeming your are not much of an OCer it might not matter to you.

You may want to look at corsairs XMS2 6400 C4 "Pro" modules they have the blinking lights but best of all they have fallen in price a lot and some of them were built on Micron ICs.
