DFI Rev. AD0 Ultra-D/Sli-D/Sli-Dr..........

http://img489.imageshack.us/img489/1...oltcore5nw.gif

My DFI Ultra-D have also very stable vcore. It is the A00 revision.

also for DFI NF4 it depends on vid + special vid combinations as to how stable it is..

eva, is there a known list of vid + special vid combos that are more stable than others posted somewhere?

I'Ve set 1,5V + 104% and it isn'T that stable :(
1,488 or 1,504 reported by CPU-Z.

@butter_fry:
PM me if you are interested in the reading point!

Eva makes a great point here.

LuckMan212 if you do a search here at XS there are a few good threads about this. In the end, you'll find that a slighly lower vid and slightly higher special net the most stable regulation.

Actually I have A01.

Interesting.

Yesterday I had my DMM on my SLI-DR and my Infinity for quite a while.

The fluctuations that the sensors reported during Prime95 were not real, the DMM kept steady while the sensors reported drops.

I did, however, confirm that the SLI-DR puts 0.025 more volts that you say you want into the CPU when it is busy. When idle you get exactly what you want and busy it goes up.

The DFI Infinity board did not show this.

I think these results are quite good for the early boards :) SLI-DR rev. R.A01

The problem is how much do we really trust these sensors :rolleyes: Oskar himself said they suck, I'll be taking the thing to school and using a scope on it.

very interested in your results as these graphs do look "too good to be true" !!;)

I ran OCCT on my two AD0 mb's with a OCZ600SLI psu. Neither would do "0" ripple but both came in about the same.

Hate to disagree with you here, but the man himself (Oskar) recommends using nothing higher that +113% special. But then again, you may be saying the same thing :p:

is there a nice guide with good pics of how to measure vcore voltages using a DMM on a DFI Expert? that would be great

Well, i Have an Rev. AA0, must be one of the first ones.. anyone heard off this Rev.? :stick:

Attachment 41758

And yes it is a .AA0 "Stupid Konsensator":p:

I Also wanted to know where to put my Multimeter to measure the V-Core, anyone know's how to?

AA0's are good boards. I think you may be thinking of A00 - those were the first.....

Yep...I'm saying the same thing. This is why I wrote slightly lower vid and slightly higher special. In fact, I never use anything above the 113% myself. I find that using the vid choices and the special from 102 to 113% gets me anywhere I want to go.

Can someone summarize this thread :)

What revision of an Ultra - d should be purchased today? :)

AD0 and the ones at newegg should be just that. Chance you may not get it though.

yup but the vid + special vid combo can vary with board to board i.e. my UT SLI-DR A.B0 1.5v + AUTO is more stable than on A.D0 Ultra-D but my Ultra-D 1.5 + 4% is more stable than A.B0

and then psu also is another factor - different psus different results

just test them all!

with my cpus never needed more than 4% or 10% special vid heh

So stephen, you got the info on the VTT mod? Jackie/Oskar say you can post it?

I tried for a few hours to pry the info out of Tony but he wouldnt budge. Just gave me the regular VTT mod which I am currently using with a SLIGHTLY boosted VTT. (with my 20k VR its 2 turns on the pot for .001 volts.)

Which board are you talking about volt modding? This board puts out enough voltage at stock? :stick:

Ultra-D. the vmodding isnt AT ALL for getting higher volts. Its for getting more stable voltage.

Stock, the DFI nf4 outputs VERY sloppy voltages for vcore, vdd and vtt. The dipping/changing voltages causes instability and reduced overclock.

With the mods I mentioned and the one Stephen mentioned Tony (big toe) was able to get around a ~10-15mhz increase in OC with some TCCD.

Ah nice

yup.

Wow, good find, s7e9h3n.

so is the info on the new mod available anywhere?:stick:
