HD7950 missing mosfet
i guys I have this Dual X Radeon HD7950
All the resistances check OK (and all other voltage rails are up) but I have a missing High side mosfet on the Vram VRM so that rail is down of course. Resistance on Vram is 60 ohm which is just fine. Does anyone know what the missing component should be? See pics - and thanks

Re: HD7950 missing mosfet
Is there a specific manufacturer for that card? I may know someone with that card but I'd like to be able to give all info available when asking.

Textolite with number 109-C38137-00 is the same as for SAPPHIRE DUAL-X R9 280 3GB GDDR5 OC WITH BOOST.
