Yes I think you will. After the initial reports of people getting the new revision of the board from newegg, I waited another week just to be sure I'd get one. Sure enough, ordered one from newegg and had it next day air shipped, and it was AD0. So far this has been an amazingly stable board. Not a crash yet and I have put this board through a total of 70+ hours of Prime95 :slobber: . It goes against the expert pretty well. Sure it doesn't have the new layout etc. but if you want to avoid the problems the expert has or has had then just get one of these. It has a more mature bios and the new revision makes it even better :clap: .

Good luck!

Yes, newegg has them. Rma'd my expert and got an AD0 ultra-d on friday from there. If you don't need sli, I'd say this version is the one to get. Currently primimg at 10x280, with my tccd 2.5-3-3-6. I couldn't get the expert over 240 with those timings.

Some info..

I´m got some more info becuse i´m so stupid and learned it the stupid way :stick:

AD0 and AB0 is the same s*it but got diffrent names:fact:

Just got my AD0 from Monarch. My idle temps are way low also, 16-17c. On my a00 used to be 26-30, depending on the room temp.

LV: My AD0 is like the one posted in this thread.. And so should most of them be. Are you completely sure you do have AD0 and that it does not have these small changes?
It sounds very strange..

OnDborder: As said before, you cannot really trust this if you got it from the sensors. They may change a bit from board to board.. And what cooling do you have, at what roomtemp?

What about my AB0 and how it resembles an AD0 (in terms of changes to componentry). LV, I found your post interesting as a very similar thing has also happened to me. I wonder what could be causing this inconsistancy.

Hmmm...my AB0 sli-d is the same as the old ultra-d......

I want what you've been smokin'.. There is physical changes on my AD0 from my AB0.. I checked before I installed.
I'm running water at the room temp, at the time, of 69f.

What model board are you runnign Ultra D, Sli-D or Sli-DR?

What exactly are the physical hardware changes that you have noticed between your two comparison pieces, besides those already mentioned within the 1st post?

Reason I ask is because I just confirmed through the distributor who imported my board into the country, the AB0 I have was apparently with the latest shipment from Hong Kong through DFI, so it is definately not an 8 month old board, about the time the original AB0's were out.
It also has the 3 listed changes as seen in the initial post, hence the reason why I think LV maybe onto something with what he is saying.

Although, this may vary with non-Ultra D models as we are seeing with s7e9h3n's experiences.

Got 2x AB0 board both have same layout and the "3-5 caps and the mosfett" are in same place like the AD0 board.

LP UT NF4 ULTRA-D(dual GB lan)
AB0 S/N:5080XXXX

Second was:

LP UT NF4-D(1 gb lan)
AB0 S/N:U5360XXXX

And the AD0:

LP UT NF4 ULTRA-D(dual GB lan)

AD0 S/N:U541XXXXX


The AD0 are soon on the way back to the shop.

Some more info both AB0 did HTT 400 and also 290mhz+ (1,1) 2-2-2-5

Well. That's around 20C. How to get 16-17c from that cooling? ;)
How old are your boards, LV? It seems the AD0's have been out for a while. I think what might have happened is sth like this:
DFI replans production of boards with these changes. They are build AB0 at the time. Oskar is building a new BIOS.
The new boards come in before the new BIOS is ready, so new boards are shipped with AB0 because it is really bios that determines the rev. Then they change bios too, and it is AD0.

Here's the AB0 Attachment 42212









Here's the AD0 Attachment 42213

Sorry about the AD0 pic. The board was already installed. It's an Ultra-D model. When I ordered it, monarch said they recieved these in the last week of Dec. I got my AB0 from mwave in the early part of 2k5.

Ya, I know it's not correct.

There is a slight difference in the boards as you can see in my pix.

Your CPU idles at 16-17C? I'm assuming this isn't air or non-chilled water... cuz if it is, there's no way your room is that cold!! :)

I've never idled less than 24-25C with water... even when my room is cold. I could understand 21-22C, but 16C? Your room has got to be freezing if you're not chilling your water (noticed you're on WC from sig).

We just confirmed that is wrong ;)

ODB: yeah, yours are, but two members seem to have gotten AB0's with the changes.

Yeah, cuz that woulda been like 60F... pretty chilly for a bedroom, but it's always to stay warm under the covers with a chilly room.

Off topic, but I've been sleeping with the window open in my bedroom every single night for the past week. My OCed opty 170, OCed opty 148, p4 2.53, monitors, vid cards and whatnot still keep my bedroom the hottest in my house, EVEN with window open... and I live in NY too, so it's a little chilly out these days.

The guy's with AD0s... do you guys see less vdimm fluctuations as well? I've been selling off my UTT left and right because I'm tired of the vdimm instability (back on TCCD on both of my DFI boards)... I feel like it's been holding me back, and I have one set of BH5 and one set of BH5 UTT left... I'm going to sell it if I can't figure out a stable vdimm solution. The expert for $200 is not worth it for me, but maybe if this AD0 is worth it, I may go for it.

Attachment 42213

My 2x AB0 looks like your AD0 :p: , can you give me your S/N on your AB0?, i think someone on dfi have used wrong stickers on some boards :stick: , My first AB0 was buyed in july

On my AB0, D51305308. If you need the one for the AD0, it'll have to be later, cuz it's installed and I need to find a small mirror.
On the temp thing, there is a thread over at DFI forums on a "temp bug" on the Expert mb. Kind of sounds alot like my situation. They read 10c lower. I'd link it but their site is down.

Where is the temp probe located anyways? Maybe it's just a bad placement and you can tilt it a bit? I think that some of the AXP mobos did the same crap, and a simple tilt of the sensor fixed it.

godman: It is in the die of the CPU, so it should be fine.

LV: mine reads U54103794.. But i think my explanation is more likely than wrong stickers, as it has been bios that dictates rev. up till now ;)

Thx for clarification, Slacker... I didn't know that the probe was located in the CPU. Wouldn't that mean that the chip is the problem with incorrect temps?
