Looks incredible! Take note of the copper heatsinks as well! I am very excited for this board and I hope they include some of these enhancements in future DFI Lanparty boards.

What is the CPL-5-50?

It replaces what normally would be the voltage regulators for the CPU

EDIT: Anyone notice a lack of the P4/P8 connections?

8-pin is right above 24-pin ;)

P.S. I hope that in a few years it all gonna be on digital PWM.

For the idiot in the forum (me), what's the main benefit of the digital PWM? Or.. what even makes it 'digital'? Yes I read the article.

Instead of using mosfets to control CPU voltage, a chip controls regulates the voltage this allows much more stable vCore (i htink)

Thanks a ton, that makes sense.

i always wonder how well these handle high current changes that would occur when the cpu is stressed. since it lacks any real capacitance. anybody care to explain how this is dealt with? :)

There are alot of ceramic capacitors there which seamed to look like resistors.
Strange thing I can`t find manufacturer of that PWM IC. Anyone has any hints about this ?

new stuff ,digital PWM , hehe

Digital PWM ain`t quite new ;)

hmm so does this mean instead of hardmodding the board, in order to go above and beyond, we would need software or bios mods

From what I can tell the manufacturer is CPL, and acording to this page, it has 5 phase power

ceramic caps are very low capacitance though, and used mainly just to deal with filtering out high frequency ripple.

how will this effect vmods?

like it was said, alot. since now there wont be as many seperated areas for sensing and feed and output and such, since everything combined pretty much into one package.

P8 connector is there, just above ATX 24-pin connector.

It's too dark to see.

Looks to be very well laid out with no clutter, too bad my 170 wont fit :clap:

very nice lookin board, too bad there's not 3rd pcie slot, or second cpu socket :D

Yea this board looks amazing, I love how they use copper heatsinks for the chipsets and how they are using an Evercool VC-RE. I think they really listen to their customers.

Though I agree with Vulgar, if it had "4x4" and a third PCI-E slot i'd buy it right away...

Does the chipset actually need active cooling?

They could've swapped the locations of the EZ switches and the debug display, tho.

i think cause it switches on and off REAL fast to get the desired voltage... large caps to smooth things out on a large scale aren't needed? but it explains the small smd caps to filter out all the high frequency noise it would make

(note: educated guess, not fact)

The most interesting thing to me are the missing PWM heatsinks. That means that even these hardcore oc boards produce very little heat - and thats great.
DFI could have the best oc and the lowest power consumption board in one - thats crazy.

The only drawback of this powerregulation is the cost - I was told.
Lets hope the boards stay below 200Euro.

That's the nicest looking layout I have ever seen on a board. I also like the 3 PCI slots. It would be nice if manufacturers would use only 1x PCI-E slot. It's almost like they use 2 just to create space gaps for the 2 16x PCI-E slots. Gotta love the copper!

why DFI not use heat pipe cooling for north and south bridge like ASUS,GIGABYTE etc :confused:

1) not enough space
2) no real difference in temps...

don´t you see the ceramique-paste on them, and the dfi-style mounting-holes?

Now they need to fill out that open space with something Nasty ;)

I Couldn't find any data sheet on that Digital PWM :(

For those who want to read about PWM, http://www.netrino.com/Publications/Glossary/PWM.html
(Its almost the same as a Switch Mode Power)
