my DFI-ULTRA D its like the 2nd pic so its ADO rev???
I would but I lent out my digicam:nono:Quote:

To FreeCableGuy- Where did you get it? I'm trying to find one!:p:
I checked the entire board and no stickers with revision :(
should be around here

my old nf4-d had RA00 and my new one has RA00 too...
It does about 380htt stable.
What do you guys mean by VTt problem?
Some of the older boards don't have a sticker. I got one back from rma from DFI direct and it didn't.Quote:

The thing is that while it is at the right value unlike what Abit can do (;)), it is not entirely stable, and will fluctuate pretty mad under load.
The problem is that you need a scope to see it, so we are not able to test it ourselves unless someone with a scope gets an AD0 ;)
Funny to think that this board is so great for oc and would clock even better if it did not have this problem :)
Yay, I got the first batch, that would be to sat a proud AA0 :(
No wonder I have FSB issues.
Different revisions have the stickers in different places. This is the second pci-e slot:Quote:

I'm currently taking a little break from testing as I've felt a bit burned out the last couple of days. I promise results soon though.....;)
huh - I bought my SLI-D from Fry's in Sunnyvale CA about 2 months ago and it's AA0 I guess... it's exactly like the 1st image.. with the resistor pins facing directly up with the two caps right near by... it's been a really great board for me... posted and booted right up on the 1st try! no hassles at all.. whew. :)
EDIT: whoa.. hold the phone... I just used the ^^ image to spot my sticker, and wow is it hard to see with SLI and water cooling, lol, but it says AB0
Lemme guess....Fry's ;)?? I'm using a Rev. AB0 Sli-D as well....Quote:

That's good... my AB0 seems to hold it's vcore pretty flat... which is what I was hoping for with the DFI. I ditched my last MSI board for vcore yo-yo.. anyways...Quote:

Interesting thread. It indeed answers a nagging question i've had for a while.
My company builds systems based on the ultra-d something we've been doing since about the 2nd month of 2005. They're primarly used for multi-display systems (DXG is a cheap way to get high power, rather than very expensive quad display workstation video boards) Anyhow, moral of the story is, i get ALOT of boads/cpus/components coming across my workbench.
About 3 weeks ago I was assembling a fresh batch of ultra-d's. As a stability test, i usually push these systems up to around 225HTT or so and prime them overnight. I chose that # because thats about where most run of the mill a64's start requiring voltage. My general rule of thumb is, if they can do 225 and hold prime overnight i'm usually good. Well this latest batch curiously went up to 235 before needing volts. not so much different, but when you've built as many of these as I have you notice when something changes. The improvment was repeatable across the 5 systems i assembled that day. I didn't even think to look to see if there was a new revision. I chalked it up to a good batch of 3700's.
Nevertheless I took one home and swapped it out for my ultra-d (AA0). Copied out the settings from the bios line for line and entered them into cmos reloaded on the new one. After a few days of adjusting and tweaking to this board, there is a vast difference in the necessary voltage versus the older revisions.
This is what I ended up with for a daily runner.

Unfortunatly i don't have a good screenshot from the AA0 that matches. If enough people are interested i can throw it back in when i get time.
what i've noticed
1. lower cpu volts (1.55 AD0 opteron 148 CAB2E @ 300x10 vs. 1.58-160 AA0 depending on the mood of the thing)
2. fewer "MOODS" that many of you may have noticed. It seems less prone to random swings in performance.
3. BH-5 Memory @ 250 AD0 = 3.30v. AA0 = 3.40 (YMMV of course)
4. Higher memory stability. not by much but with the same settings i'd say 2-3HTT
again i'm glad someone noticed the revision, as i'm too dense to actually observe things like this. I could have reported on this weeks ago but i thought it was a fluke, or i had gotten a golden batch of boards.

Here, i dug up some old OCCT graphs.

The difference is striking
