Nope. Been a bit busy tonight! . I have a nice 120mm 2400rpm over it too (having just come from BH5 @ 250mhz and 3.5v) so I'll know soon enough whether it will go. I'm think I made the right choice with this stuff...but off for a quick game 'test' now .

Let me know how you get on.

Hey Smids, anymore news?

Yeah, I think I'll be sticking with timings (ZX). Running 2-3-2-5 1T @ 208mhz fully stable and I need no more thanks to the divider. Bandwidth loss is about 500mb/s over 250mhz but I doubt I'll notice it + I don't have to run @ CAS3.

Is there quite a performance hit with CAS3 vs CAS2 do you know?

Im sure you can do better than 208mhz, come on crank it up

Well I think the point is, CAS3 is fine if you are running 250mhz but will not run any better than say running 200mhz cas2. Yes, you get more bandwidth, but going by what Angry-Games posted, this is irrelevant due to the mem controller being on die. The Intel memory controller has to pass information along the bus, so bandwidth plays a much more important role.

So for all intents and purposes, timings of like 3-3-3-8 1T 250mhz = 2-2-2-5 1T 200mhz is my understanding from his posts and reading up a bit on the net on this issue. Then again, if your PC4000 can do cas2.5, that's a whole different ball game.

I'm very happy with my choice, tight timings and running 208mhz. I'm running on a divider but I'm used to that having had BH5 RAM for the past year.

I think that's about right I get roughly 2/10th's second better on 1M super PI with 250 MHz @ 2.5-3-3-6 (but that was with my OCZ Platinum Rev 2) as opposed to 2-2-2-5 @ 208MHz ? around 208 can't remember the divider but it's just over 200. My G Skill HZ 4000 can't do 2.5 CAS @ 250MHz so I can't do a true comparison but I'd imagine it would be fairly close nothing to worry about unless your going for world records.
