Oooh sweet, OCZ must be the first into the forray of 1800mhz, my next upgrade will be DDR3 for sure.

First off, I'd like to thank OCZ for their quality products and excellent customer service. I have used many OCZ sticks (from DDR to DDR2) and they are all high-quality sticks (except one or two cases which are kinda expected when you deal with dozens of sticks). Most of them were awesome deal at the time of purchase, too. Thanks OCZ for the great products and the participation in enthusiast community.

Now onto off-topic :D : Sorry I know this is a DDR3 thread but since we have an OCZ personnel here I thought it's a chance to ask - Is OCZ planning to make performance-oriented 2GB DDR2 DIMMs? For new builds today I would definitely go with 4GB configuration and I prefer 2 x 2GB to 1 x 4GB for obvious reasons (heat, stress on NB, etc.) I guess this applies to DDR3, too. By the time DDR3 becomes popular, I predict 2GB sticks will be the norm, just like today's 1GB sticks. I do know there is a 4GB kit from OCZ, but the specified timings aren't too exciting. (Something like DDR2-800/5-6-6, IRRC) So wondering if there is any new product coming out..?

eva2000: I saw your results and they're great. Indeed I think it's the best 32M time I've seen with C2D @3.60GHz (13 min 12 sec). seeing that the vDIMM reads 2.0V (and knowing these chips are from Micron), I'd guess the clock scales well with voltages? How hot does the sticks get? Do you use any special cooling at such high voltages?

Historically most (all?) high performance Micron chips (DDR/DDR2) tend to scale better with voltages than any other chips, but at the cost of high voltages and possible degradation (due to heat, electro-migration, or what not). I wonder what's considered a reasonable voltage/temp ceiling for 24/7.

Another question: How many dividers are *practically* available with P35+DDR3 combo? We know that there is unspoken (or rarely spoken) secret with Intel chipsets - dividers are kinda broken. Except 1:1 which is obviously working on all chipsets, a certain chipset wouldn't work well with certain dividers when overclocking. At least with DDR2. Now, with these high frequency DDR3, I do understand 1:2 is ideal ratio, but is there any other divider available (again, practically - meaning no extreme voltages or cooling) for less-than-ideal situations? If so, which one?

@DDR the voltage scaling king was Winbond , sorry :D

DDR-3 2GB Sticks can come easier than the DDR-2 micron parts, as the new hot DDR-3 ICs, the Micron Z9 are 128MB ICs, so with a double-sided stick ( 16 Micron Z9 ICs ) you have a 2GB stick.

Better DDR-2 2GB DIMMs are probably of the IC manufacturers 'targets' now probably ( more or less, they've started focusing more on DDR-3 ICs ), but who knows, some manufacturer might come out with a bang! ( LOL, could it be Elpida ? :p )

The Z9 are scaling fine even up to 2.35V :D , and from the looks of it, they're taking the voltage nicely.

On P35 DDR-3 we have lots of working dividers :)

yeah Micron DDR3 ICs scale well with voltage but can't say I know what is safe or not.. first play with DDR3 platform myself heh

P35 has the most divider options and well for DDR3 it's the only chipset out there besides the X38 that is coming.

Ultimately for Blitz Extreme, you have access to 2:3, 3:5, 1:2 at 266FSB default frequency, 5:6, 4:5, 2:3, 5:8, 3:5 and 1:2 at 333FSB frequency and 1:1, 5:6, 4:5, 2:3, 5:8, 3:5 and 1:2 divider at 400FSB frequency. You'd get a various mix of the listed dividers at different FSB frequencies, I just listed common ones for you.
