XFX XXX 7900GS Volt Modding

[BTK]

I want to volt mod my 7900GS. It's the 600M XXX Edition. Stock factory clocks are 600/1,600 MHz.

The RAM (Hynix 1.4 ns) clocks well so I want a VGPU.

That's mine.

That's not stable. It runs stable @ 610/870 (1,740 MHz)

I can't use any 7900GS/GT guides because the PCB is different.

It looks like this.



That's not mine. But that's what it looks like. That's the 450M version.

So I got the codes from the voltage regulator chips.

APW7067N
A19U1 = same as ISL6549

63H2DXK_G4
ACT08

4410
BE6S1K

4420
BA6V13

The only one I could find solid info on is the first one.


APW7067N
A19U1

It seems that it has to do with OCP and what not and will not help my vmodding

--------

The only other code I kind of found in on was 63H2DXK_G4
ACT08

----------

If I could fine the regulator that is for vmem and vgpu I could use a pencil or solder and get a multimeter.

The 450M has RT regulators and mine doesent which is even worse for me.

See what a vmodded 7900GS can do.



Help would be appreciated.
