HW will run 2x8's as easy as SB and IB run 2x4...

So the overclockability will be higher on the 2x 8GB versus 4x 4GB? I've noticed the fastest RAM on Newegg is 4x 4GB kits. I thought though it's much harder to overclock 4x 4Gb versus 2x 8GB, maybe that's old info.

As long as RAM is error free, there is a certain range of capable settings that can be used where the system will be perfectly stable. This is in response to some one that thinks because RAM is 1.65V, it will make a computer unstable. false. RAM is only unstable if settings out of it's capable range are used, or if the user did not input the correct values. Hardware is properly designed, so if it is used as intended, it will work just fine. It would be quite a liability to produce hardware that can damage other hardware.

If we are able to run Haswell at 133 and 166 FSB. How do we even know if the current memory modules will even run at those FSB speeds? Since the current memory modules are only rated at 100 FSB.

Haswell doesn't have a FSB, nor does any Intel part post LGA-775. Nor does memory care, or know, what the system base/reference clock is. Plenty of people here have run DDR3 on systems with FSB speeds in excess of 500MHz or BCLKs in excess of 200MHz. I was running a 200-222MHz base clock with DDR3 in early 2009 on my LGA-1366 setups.

Memory clock is all that matters and Haswell has multipliers for memory clocks so low that even if you are able to use 166MHz baseclock on your part, you should not be limited by the speed of your memory unless it's exceptionally old/slow.

Chances are DDR3-1333 will be sufficient to achieve the highest CPU clock speeds practical on Haswell.

Perhaps...but how much fun will that be???

Bring on the DDR3-3000...to infinity and beyond! smile.gif

You can go buy yourself single sided 4gb hynix DIMMs if you like haha, but i wouldn't use that for benching, but that is what everyone seems to use for the 4ghz stuff.
