We have been using Mushkin Memory for quite awhile and have no problems with it.
Thier PC3200 Black PCB is rated CL2 and 6-2-2-2 guaranteed settings to run in the nF2 ASUS mobo's. I always get Cas 2 IMO this is best.
We have been using the PC2700, PC3000, & PC3200 black pcb.
I would compare this memory as even better than Corsair, mainly because they have not had the controller problems that Corsair had some months ago.
Mushkin is not cheap memory, it is priced in the XMS Corsair area.
Prior to this we used Crucial, the reason we changed is Crucial was too slow to get into the hi end memory products.
These new mobo's demand PC3200 and above, and they failed to produce a product that will work in these systems.
