memory timing question

2-2-2-5 is better because when it comes to timings lower is better (for performance anyways).

Tighter timing are always better.

I disagree. Increasing tRAS by one might not affect performance at all. For real-world aps, even tRAS 8 keeps up with tRAS 5. But if tRAS is too tight, performance may suffer even if the system appears stable. Mushkin explains it better than I can this late at night.RedDragonXXX said:

I'd bench them both and go with 6 if they bench the same. I'd also give it a hard run on Prime95 before using 2-2-2-5 as my 24/7 timings. If I didn't have time to bench it, I'd just use 6, as setting tRAS lower than tRCD+CAS+2 is asking for trouble.

Yeah, that's a good way of explaining it. What I've never understood is why slamming the book in the CPU's face can slow things down without crashing the system or at least causing major stability problems. Perhaps the memory controller is smart enough to try again when that happens.IWasHungry said:I liked the "book opening and closing in your face" analogy.
