What do you say about Patriot?

What do you say about Patriot ddr400 cas 2-3-2-5 (2 x 512)?
How can I overclock them?

I owned a 2x256mb XBL kit and they works really well. I'm currently running them at 250 1:1 with 2.5-3-3-7.

I'm not sure what you meant "How can I overclock them" but all I can say is overclock the hell out of it.

You are talking about two different types of ram. The XBL is TCCD as is rated at 2-2-2-5. The LLK is rated at 2-3-2-6 and I'm not sure of the chip. Patriot ram has gotten some decent reviews. It started out as a super bargain, but more recently the price has risen.

i think its hynix chips on those .. only the 2-2-2-5 had the tccd's i believe on the patriots and other brands .. hynix arent that bad of chips as i said before n other threads .. i had a pair to play with for a couple weeks while a friends pc was getting overhauled.. i didnt see any good results with lower latency's but it did pretty well runing cas 3-4-4-8 .. 3 volts .. i went up ore volatge but didnt see stableness when getting higher fsb .. so i backed down . all in all not bad chips .. but they are no tccd's
