My vDIMM can go up to 2.9V... is CH-5/BH-6 right for me?

My vDIMM can go up to 2.9V... is CH-5/BH-6 right for me?

I understand that these two chips like voltage, BH-6 moreso... if the highest I can go is 2.9volts on my mobo, then which chips should afford me the best performance (all other things aside, and assuming they're rated at the same speed)???

I'm ignoring BH-5 for the moment, as I'm pretty sure my chances of getting some are at best iffy now for the speeds i'm looking at (and that's a whole 'nother can of worms), so please no mentions of BH-5 here thanks

EDIT: and by performance I mean both a high FSB and relatively tight timings...

On the same speed rated sticks, I'd take BH-6 over CH-5 any day of the week.

I agree. You will get much better timings with the BH-6 and at 2.9V you will get a pretty good fsb speed.

bh-5 or 6. you wont be able to give ch5 any more then 2.6, or 2.7 (if your lucky).

ch-5 does not respond to more than 2.75.
