Final GIGABYTE X79 Boards with Digital PWM's Pictured!

GIGABYTE with a digital PWM. Uh-oh ... !!

(PS: better quality pictures can be found at Facebook)

It seems that GIGABYTE has done a final revision change on their whole X79 lineup, as the boards we saw at IDF 2011 are not going to be those sold in stores, the presentation below showcases the new boards as well as some new technology. GIGABYTE calls it 3-Way Digital Power, 1 CPU Digital PWM, and 2 Memory Digital PWMs.

We have come across a presentation showing GIGABYTE's final X79 lineup, with some changes including the use of International Rectifier Digital PWM’s. The PWMs in the picture do not seem to be on IR’s website, as they are most likely based upon Chil’s Digital PWM technology, as IR now owns Chil. IR recently acquired Chil Semiconductor, the maker of most of ASUS, ASRock, and Intel Digital PWM’s. Now it seems that GIGABYTE has acquired IR/Chil’s newest PWM technology as these controllers seem to be VRD12 and VRD 12.5 certified. Let’s hope other vendors have acquired the same updated PWMs on their X79 boards. Digital PWMs are used not only the CPU, but memory power as well. GIGABYTE is now using Digital PWMs on their X79 boards as far as we can tell. Take a look for yourself.

It is a sad day for Ziker Labs, but a great day for users digital is the way of the future, and now the second largest motherboard manufacturer has incorporated digital PWM technology, making analog a relic of the past.

Many overclockers and enthusiasts will welcome this change as Digital PWM technology allows for total control of the power delivery, as well as increased power supply density, and a much more precise voltage regulation scheme.

We don't want to break Intel's SB-E NDA, so we cannot divulge any more information at this time, for now enjoy the final pics of GIGABYTE’s X79 lineup!

oh deal god!

How come the UD7 has 4 RAM slots while the UD5 has 8?

Finland IceBlood says:

Well, you won't do mighty overclocks with 8 DIMMs anyway.

Assasin vs other models:


Taiwan Tim Handley says:

The UD7 and UD3 are the OC boards each with 4-way SLI/CFX. The UD5 is for content creation with 8 memory dimms and 3-way SLI, and of course the Assassin 2 is for gaming.

K404 says:

Is it just me or are the pictures still showing analogue-PWM?

With UD7 being the full-blown OC board and the UD3 being the entry-level OC board, I assume?

The line-up is a little bit different from the X58 one; it will be interesting to see how it pans out.

Australia Jimba says:

some good boards but you would think that with the UD7 been the top model it would have the most features.. i hope gigabyte will release a 4 way SLI/CFX compatible board with 8 dimm slots it can double as a good overclocking board + a content creation monster! i wish! :(

South Africa chickenbeef says:

^Maybe they'll release another UD9.

Australia Dinos22 says:

heeeeeeeeere weeeeeeeee go :D

Sweden ME4ME says:

UD7 looking good. :)

+1 :)

Fixed, except for the shadow.

United States xxbassplayerxx says:

Better, except the A2 needs to be resized to be the same height as the UD5. Looks like ATX, Not XL like the UD7.

United States sin0822 says:

im excited!

United States xXSebaSXx says:

But I thought Jiggy was going to be making the X79-OC... By the look of the UD7; that is going to be the new "OC" for the chipset. Or maybe Jiggy is holding out on us?

Australia Jimba says:

is the UD7 XL-ATX? i thought i was E-ATX and the others where normal ATX?

Australia Dinos22 says:

i think UD7 occupies one extra slot which a lot of cases will be able to handle for standard ATX boards anyways. It's certainly nowhere near as long as UD9

Gotcha. I just looked at an image of the UD9... it has an extra slot lower than then UD7. You can tell by comparing the screw holes.

Also... even though I love the OC... I'm kinda missing my UD9 for some reason.
