3870X2 voltmod thread

[K404]

Im assuming the mods will be slightly different, so will treat this card separately. Please can someone post up high-res pictures of the back of the card, and we can take things from there.

Cheers!

I think these should do the trick

[jimmyz]

Wizzard provided these for voltmodders on techpower-up. I am posting the pics and a link to the article.he also stated he was able to oc with a combination of atitool and CCC. so we just need more voltage

[zbogorgon]

now we only need which pin to the ground

[zbogorgon]

So what AMD ban doing mods also ? Can anyone even tell me where can I get info about that regulator or regulators.

[T_M]

Ban? Huh? WHat are you talking about?

[zbogorgon]

AMD is just stupid with all this limitations and all, first 860 Wall, then no tools to overclock, again, very limited Overdrive, no drivers for Xfire al all, they are like top secret or sth and so on, no mods what so ever, noone even says anything, so I ques this is their secret to or sth ?

[G H Z]

I hear you zbo, they recruit a well known overclocker but don't appear interested in cashing in on that relationship or the enthusiast crowd.

Hey we can always run the green cards

[youngpro]

if anyone has info on vmodding these cards, id love to try it out

[SF3D]

Relax guys These have been out only few days now. I'll have mine tonight, so I can start to look Vmods.

Controllers are the same Volterra 1165MF like in 2900XT.

Maybe someone could measure resistance in this spot. (second pin from bottom)

give me SLI on X38/48 and I will say AMD good bye

p.s. I'll measure resistence, just give me a sec

*dreams*

Please can someone post up a picture of the whole of the back of the card? Was gonna suggest using PCI-E GND, but thats crap if 2 of the voltmod spots are half-way across the card

Which volterra controller are they using? I cant make out all the numbers in the pic. VT1165MF? Apparently it offers software voltage control too

Cheers!

Here are the mods by Sham:

[zbogorgon]

thx elmor, good old Sham, he never let's us down, thank both of you again

[T_M]

Now to find more convenient locations that wont be under insulation...

[SF3D]

Thanks Jon! I got that e-mail too just a moment ago

I will watercool this card and try to achieve similar clocks as my 3870CF setup. 1080MHz on water is not so hard to do.

[AndreYang]

Thanks Shamino.

[MuffinFlavored]

I don't know Shamino at all, but this just makes him, "the man".

[jimmyz]

On these forums he is known as Lardarse... he is a Legend in every sense of the word.

[Pt1t]

Thanks Shamino



With 1.42v , gpu's does 3D @ 1ghz stock cooling.

Pt1t, what were the "real" clocks as shown in AMD GPU Tool?
If anything above 985 real, then you have the fastest clocks so far.

Guys, for your memory please be sure to sink them on the backside. Since i did the vMEM mod, I'm getting occasional artifacting/massive screen corruption when running at my previously benchable mem clocks

it s 999mhz real.

[spajdr]

can this be used as pencil vmod?

[Pt1t]

it s 999mhz real.

Now it does 0mhz
