elmor Posted May 16, 2013 Posted May 16, 2013 (edited) 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? edit: vgpu: edit2: LN2 bios: http://elmorlabs.com/files/7790ln2.zip Edited July 12, 2013 by elmor Quote
Christian Ney Posted May 16, 2013 Posted May 16, 2013 I can do that tomorrow morning at the office, do you need pics too ? Quote

Christian Ney Posted May 17, 2013 Posted May 17, 2013 (edited) 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. Pics: Thumb: 200x134 Normal: 800x600 Original: 5184x3456 #48 is this one right? Edited May 17, 2013 by Christian Ney Quote
Eeky NoX Posted May 17, 2013 Posted May 17, 2013 Can't wait to see how high this chip can scale (not a bit too late for MOA class B?) Quote

Eeky NoX Posted May 17, 2013 Posted May 17, 2013 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 ^^) Quote
FireKillerGR Posted May 17, 2013 Posted May 17, 2013 I have a 650 ti boost over here I am still confused though; will it be better than a 560 448 or no? Quote
Eeky NoX Posted May 17, 2013 Posted May 17, 2013 Guess not! Look at the last screenies for 7790... Taking 1500mhz oO with tesselisation off imagine what... Quote
FireKillerGR Posted May 17, 2013 Posted May 17, 2013 F@ck I really forgot about this thing aka tess -.- what can I do now? Will have to give it a shot Quote
Eeky NoX Posted May 17, 2013 Posted May 17, 2013 A bit off topic mate but, don't forget 50% of contestants will go to semi final Push hard and do your best!! Quote

elmor Posted May 17, 2013 Author Posted May 17, 2013 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. Quote
Christian Ney Posted May 17, 2013 Posted May 17, 2013 Sorry wasn't 1390 ohm was 1390k ohm (1.39M) which seems wrong ... Quote

icebob Posted May 17, 2013 Posted May 17, 2013 The other prob, at least with the MSI variant, is that it cold slow, so I guess a bios will be needed too... Quote
icebob Posted May 17, 2013 Posted May 17, 2013 As soon as I went into negative temps, I was getting like 10fps on 11, warm it up and back to normal... Quote
icebob Posted May 18, 2013 Posted May 18, 2013 tried again last night, anything colder than -10c = cold slow! Quote
