I happen to have the NCP81022 datasheet but no HD7790 card at the moment. Anyhow the feedback pin is #48, can someone measure resistance from this point to ground?

I can do that tomorrow morning at the office, do you need pics too ?

 

Would help yes.

1'390k Ohms (1.39M Ohm) from #48 to GND.

 

Btw, on my side I have a 7790 with PCP81022, I don't have the 7790 with NCP81022 anymore.

Thumb: 200x134

#48 is this one right?

Lol so do I... prep this week end and firing next week!

 

Seems 560Ti 448c gat no chance to outpass this card... pff! need to buy one now (...once again ^^)

I have card with NCP81022, I`ll check the resistance.

A bit off topic mate but, don't forget 50% of contestants will go to semi final ;) Push hard and do your best!!

 

yeah and also ONLY 2 will go to the finals :(

 

anyway sorry for the off-topic. rest in pm :D

Pin #48 is that one yes. VR of 10kohm should give a little more than 10% increase in voltage. OVP is at +0.3V so still need to figure something out there. Unfortunately it uses serial vid interface so no VID-mod is possible.

easy we use Epower

Sorry wasn't 1390 ohm was 1390k ohm (1.39M) which seems wrong ...

 

yesterday I measured 186kOm , but my battery is low .. so i didin`t post it)

The other prob, at least with the MSI variant, is that it cold slow, so I guess a bios will be needed too...

As soon as I went into negative temps, I was getting like 10fps on 11, warm it up and back to normal...
