Ok, heres some of my work for you guys

The Vcore mod is done using a 50kohm variable resistor set to 0 ohm. You increase the vcore by increasing the resistance. As you can see you connect the resistor pins to the black and white cable. There should be a 0 resistor there, you have to unsolder it

The stock voltage is:
1.1V in 2d
1.35V on rev. M cards in 3d
1.45V on rev. H cards in 3d

The Vddr mod is something like a Vdd mod on a Radeon 8500/9xxx

I used a 50kohm Variable resistor set to 50k, the second pin is connected to ground. You increase the voltage by decreasing resistance. The stock voltage is:
2.5 to 2.55V on rev. H cards
2.6 to 2.65V on rev. M cards

Oh i forgot. The green wire is the Vddr mod

And now im attaching the bios file, with this bios you should do from 1100 to 1200 mem clocks

[berkut]

And heres part 2, its with the nvidia flasher already

[copyman]

some idea where the points of measurement of the vcore and vmem are?

tks

[Georgi]

The one I have here is rev. J
... any suggestions?

[Georgi]

Bump

[berkut]

the rev. j looks the same as a h and m

And what about the stock voltages on Rev. J ?
Can you tell me where the measure points are?

[Snigel]

Two questions:

What voltage do I get on the core with the mod?
I have a rev J by the way.

Second, by changing the bios I can up my memory, but do you know if it's just worse timings or that you actually get higher voltage or something?
Have you looked at your score at the same speeds using original bios and the ultra one?

Come on berkut We are wainting eagerly for this mod ! give us some reading points!

[Bra!nFreeZe^]

Arent there other ppl that would know how to mod this ?

By berkut.....
---------------------------------------------------------------

The capacitors on top right are for Vcore, on the bottom righ are for Vddr

Im still working on the remaining Vmods


too bad my old card is dead, it would OWN everything we've got (585/1170 clocks on a funny air cooler, no mods)


--------------------------------------------------------------

now it is only try to reach me friends

Damn berkut thats really bad ! how did it die ?
Thx for your reply now Im only waiting for my mobo...then Ill mod my card!

Nice

I think i will try that mod on my TerraTec Mystify 5800 Ultra





Now it*s go 500/1000@550/1240 and i hope maby with mod 600+/1300+
