Quad SLI Z87 Motherboards

PCI-E lanes are on the CPU, the CPU has 16 of them and 4x 16lanes is 64lanes. Adding PLZ chips etc raises lanes to around 32 so most quad systems will run 8, 8, 8, 8.
 
Thanks for responding so quickly :).

Will there be any performance hit running in 8,8,8,8? Gigabyte doesn't seem to support this and was looking at a MB for SLI in Windows and that will also work in OS X (Gigabyte work best apparently). Any good recommendations?
 
I think the Asus Maximus Extreme 6 can run this way as can the OC Force and Sniper 5 other than without going over them all I wouldnt be able to say.
 
If you want Quad at 16x one of the only boards I know of is the ASUS P9X79-E WS. Not Z87/Haswell and pretty expensive but will do it. You could pair one of those with a i7-3820 for not far off the same money as a i7-4770K and a maximus extreme board.
 
OP if you want to go quad sli X79 would be a better platform. If you use Haswell the CPU (due to poor overclocking headroom) will bottleneck the GPUs.
 
OP, the ZXSpectrum is correct in saying that that board is one of the only boards that can run 16 x 4.

Kaapstad, thats a bit of a generalization. Im at 4.8Ghz on air witha 4770k and 2800MHz memory. You would need 5.3GHz and 2600MHz on IVY and god knows what speed on sandybridge to match that.

It is a bit of a generalization yes but by the look of it you seem to have one the better 4770k chips. I have seen plenty of posts where people are topping out at 4.5ghz. With 1 or 2 Titans and maybe 3 in some things the extra efficiency of the 4770k will help, when you get to 4 Titans efficiency is less important than out and out CPU clock speed. You can score more on 3dmark11 running @PCI-E 2.0 x16/x8/x8/x8 than you can by running PCI-E 3.0. It is more important to get the CPU as high as possible with stability than to run efficiently with PCI-E 3.0. Having said all that I expect 8 Pack will be along in a bit with a screenshot of a 4770k using exotic cooling, now that is an entirely different game.:D

I am not against Haswell at all, I am thinking about building a rig myself for use with one or two card setups.

This is the board I am looking at

With either this Ram

or this

Plus a 4770k

With this setup I could have some serious fun benching a Titan or a pair of GTX 780s.:D
 
OC force is a great board Kaap I have a watercooled rig in the office at 5ghz/2666mhz RAM C9 ;) 24/7.

Christ on a bike, what does the OC-Force do over the regular OC to warrant the £300 price hike??

That is one expensive motherboard to the point its in dual socket territory!!
 
Yeah. Those fans are for nothing more than cosmetics really. Z87 power delivery on this board does not get hot.
 
If your buying four expensive cards for quad you may as well get the bets board available to make sure they are performing to the max.
