K404 Posted May 25, 2013 Share Posted May 25, 2013 I did the OCP mod as shown: Now i'm struggling to find software that will let me take the vCore over 1.21v. I've tried Asus SmartDoctor, nVInspector (of course) and Afterburner with the voltage unlock tool.... it cannot find the patching location. Any help appreciated Quote Link to comment Share on other sites More sharing options...
Gamer Posted May 25, 2013 Share Posted May 25, 2013 Use the MSI afterburner 2.1 + Voltage unlocker. Works great here. If you can't find them, give me a pm with your email. Quote Link to comment Share on other sites More sharing options...
K404 Posted May 25, 2013 Author Share Posted May 25, 2013 I tried 2.1 + volt unlock. The slider goes to 1.40v, but if I "Apply" more than 1.21v, the slider jumps back to 1.21v It's confirmed by a hard readpoint. It's progress of some kind... at least voltunlock can patch now!

Gamer Posted May 25, 2013 Share Posted May 25, 2013 Sorry, forgot I have a lightning. Isn't the bios limiting this? Quote Link to comment Share on other sites More sharing options...
K404 Posted May 25, 2013 Author Share Posted May 25, 2013 (edited) I have no idea. It's a CS BIOS.... I don't know if that's useful info or not FBE won't let me push over 1.21v, but I kinda knew that already.

Andrix85 Posted May 27, 2013 Share Posted May 27, 2013 This thread interesting also me. I have a MSI GTX 580 TWIN FRROZ II and I havn't do mod. With MSI AFTERBURNER i can go to 1.15V. For 1.23V have you mod the bios K404 ? Have you used ASUS GPU TWEAKER ? Quote Link to comment Share on other sites More sharing options...
K404 Posted May 27, 2013 Author Share Posted May 27, 2013 I have still to try a custom version of SmartDoctor that I found on my hard disk, but every other piece of software i've tried maxxed out at 1.21v real (=1.25v idle, measured with DMM) Quote Link to comment Share on other sites More sharing options...
Ceresara Posted May 27, 2013 Share Posted May 27, 2013 This thread interesting also me. I have a MSI GTX 580 TWIN FRROZ II and I havn't do mod. With MSI AFTERBURNER i can go to 1.15V. For 1.23V have you mod the bios K404 ?Have you used ASUS GPU TWEAKER ? For reach 1.213V (software), unlock the BIOS with FBE. If you have unmodded (K404 mod) ref card and you wish more volts, you will try with 1.6.0x version of the MSI Afterburner for bypass the limit (the GTX 580 ref has same voltage regulator of the GTX 480 ref, so, i think this version of MSI AB can work this "trick" for GTX 580. @K404 Have you tried the BenchZowner firmware mod for disable protections? Maybe.... http://www.benchzone.com/forum/viewtopic.php?f=26&t=37 Quote Link to comment Share on other sites More sharing options...
K404 Posted May 27, 2013 Author Share Posted May 27, 2013 I've not tried Bills firmware mods. Do they actually work? I have slightly damaged my card- I cannot put the OCP components back on, then increase vCore with software. I am stuck with this situation Quote Link to comment Share on other sites More sharing options...
Bobnova Posted May 27, 2013 Share Posted May 27, 2013 Seems like there has to be a feedback/vsense+ pin you can attack somewhere on that card. Even if the FB pin itself is toast due to the OCP mod, there's still vsense somewhere. Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted May 28, 2013 Share Posted May 28, 2013 If I recall, Afterburner 1.50 Extreme, 1.51X, or 1.60 beta 4 is the one to use for GTX 480/580... Quote Link to comment Share on other sites More sharing options...
