This is how I see things personally. Corsair is taking the memory pieces and testing them together. If those pairs work at FSB higher than their rating while under extreme stress, then they lable them as TwinX units and you pay a preimium for their tests.

I presonally just make sure that I buy (2) identical sticks from the same place at the same time. That way (unless you get a dud stick) those two sticks should be able to work great together. I currently have (2) 256MB Corsair PC3500 sticks running @210FSB with 2-3-2-2 timmings. I have a slight instability that I am expereiencing but I am not sure if it is the CPU or the RAM timmings that are causing it. Still, even if I have to go to 2-4-2-2 timmings, that is some great RAM.

Corsair has provent to me time and again that it is worth the extra money to buy their products.
