View Full Version : Check this old Volt Mod out

I am going through pictures cleaning them up and I came across this.
this was a volt mod, my friend Dmitry did for me about 1.5 years on a R9700 pro, when I didn't know how to volt mod and had no reading equipment.
I was extremely aggressive about learning overclocking, my only time overclocking was the time it took for me to get my prometeia to come from over seas.
volt modding was kinda the same.
I heard about it, and I wanted to try it.
just I had no idea about any of it, and how to do it.
well dmitry was cool enough to come up with this mod for me.
only now, a year and a half later, when I know how tough some volt mods can be, or how nerve racking it is everytime I heat up the soldering iron, wondering if this hardwares gonna live or die...
only now, do I really see, the kinda work he put into this mod for me.
cause I know, if I tried this one myself, I'd buy a different videocard, haha...
one thats easier to mod.
this mod, as you can see was done with a dipswitch, alot or resistors and pretty much made to be idiot proof.
all I had to do was set the proper combination of switches to get whatever voltage I want.
it controlled both Vmem and Vgpu.
if I remember right, I had up to 1.85 volts for the core, and 3.1 volts for the ram, but I honestly can't remember.
I just thought I'd share this mod, cause I know I haven't seen another like it since :)

and finally...
anyways, thats all of them.
all I have left of this particular mod.
the card lasted about 5 months with me, before one late night I was really tired, and benchmarking, I put my pelt on the videocard, and turned it on...
only to wonder "whys my temp sensor say 220"
"whats that smell?"
I put the pelt on the wrong side and cooked the card, cause I was sleepy and wasn't paying attention.
it was a fun card. :)

Ya that mod reeks of *looks around* quality!
Someone wanna tell me how dip switches work? lol, it seems its a lot safer to use fixed resistors and using dipswitch with 1 vr to do all vmods :)

very nice, but why the dip switches?

Very well-done mod.
PRanganathan, each dipswitch connects a different value fixed resistor into the mod circuit. By closing a dipswitch you add that resistance value into the circuit, much like turning a VR to increase the ohms.
By closing a switch, this circuit looks like it adds the resistor to an initial resistance value. Close two switches, you add two resistors, etc.

well at the time, I didn't know anything about soldering or how to do it, or even how to use a volt meter.
that didn't stop me from wanting to try it...
so I was talking to my friend dmitry and he said he had a idea how to do it, so it would be safe and workable for me.
at the time, I had watercooling for my videocard, so he tried to give me voltages he felt would be safe for water.
it took about 2 weeks to get the card back and when it was done he said, he's never doing one again, it was too hard.
but when I got it back, it did indeed work idiot proof.
all I had to do was select the value and do the OC, and sure enough my card just kept getting better and better the farther I pushed it.
if I remember right 5 switches were for the GPU core, and 3 for for the Memory.
I have since learned all the volt modding stuff myself.
I suck at it I say, so I still practive alot, but I am getting better everyday.
but I finally really appreciate the work that went into that mod, even more then when I initially got it.
cause now I know, how much thought he put into it, and how much he helped me out.

LOL Love the dilbert sig!!
Damn... I want a volt mod like that on my raddy 9700...

Well. He sure did a better job than me.
BUT HEY! He forgot the Vddq and Vref mods :P
Here's mine anyways.
Or maybe not. How the hell do I attach a pic.
:confused:
*Looks through FAQ*
*Done* Seems I can't :)

You need to have a host to post the pic up first :)

Okay. There we go. Incredible what you learn when your forced to it :)

The two white coreds that seem to lead to nowhere are there for easy voltage mesuring. They lead to two old fan plugs. Only one of them are solderd on here.

Hey that's a sweet mod Kunaak.
I wanted to do approximately the same thing but never thought about a dip switch, Switch on-switch off......easy.
I was worried about careless other hands flipping the switches....thats what stopped me.

how high did you get the card to run at?
Kunaak

to be honest I don't remember.
475 I remember on the core...
mem, not a clue.

That's a damn nice oc for a 9700! :slobber:

Indeed damn high... now go and don't return before you have a decent 3dmark score ;) :thumbsup:

Why use the dip switches when you can just use a variable resistor?
