Zck250-
I checked back, and my source on that info for the Corsair is a bit dated now (which means about 12 seconds old in the computer world

) Apparently for awhile, Corsair was handpicking Samsungs 7.5ns PC2100 chips to make their PC2700- which doesn't surprise me- lots of guys have been running Samsung's PC2100 at 190 and up. I would expect they've switched to 6ns chips by now, as they like to stay on top of the game..
For Corsair fans, here's a link to a test of their latest...

It's a single-sided stick- Tests are showing they tend to be faster, but can give more trouble when using more than one.. that was the story on the single sided 2700 anyway..
and a good info source (forum moderated by Corsair employee..)

I've had awesome performance from Mushkin's SDram- they've been a little slow to pick up the high end of DDR, but I'd be very surprised if they put out a product that didn't do what they claim it will, and then some.... anyone know whose chips they're using on their 3200 yet..?
