Hi. I need help.
This is very rare card on PCB from 9600, may be PowerColor. I need vgpu and vmem or useful links or datasheets.
All in the pics:

the PCB is exactly same with Gigabyte R9550...
so here is the mod. My friend, embuh, was trying to mod his card, and it's successfull.

sorry, AFAIK no vmem mod for this card. But without vmem, this memory can run @ 330 MHz, that's quite big jump from 200 MHz.

Only gigabyte has vmem mod on 9550 :)

For the Vddq mod, connect a 10 or 20k variable resistor across the resistor marked on the atached picture. If someone can get a closer picture of the area I've circled, I'll look for a Vdd mod as well :)

I can give more quality pics later.


connect a 10 or 20k

So 10 or 20? Fear... :)

Either will work - use 20k if you want the modded voltage closer to stock, or a 10k if you want more accurate voltage adjustment at higher voltages :)
