  1. So, I tried the modded bios, but now the card is temp throttling . It stays at 835mhz, but when the gpu hits 82*, the cpu usage goes to 40-50% and the fps in games are 10. So I reverted back to the original bios and started to play with the clocks, to find the "stable" clock. I found it: 850mhz and 1300 memory (stable 78*). I noticed that at these speeds, the voltage stays under 1.000. If I overclock it above those clocks, the voltage jumps above 1 and the card overheats. When I return home, I'll try to re-paste the gpu, but those voltages got me concerned, Is it possible to undervolt the card? I remember back in the day I undervolted my desktop video card and processor, and the temps got 10-15* lower. If I try default clocks 745mhz and 2000mhz memory (under load - 1.012v), the gpu still throttles If i try 850mhz and 2000 - the voltage stays the same 1.012 still throttles if I try 950mhz and 2000 - the same 1.012 So the voltage never really changes at these speeds, but if its above 1.000, no matter the clocks, the gpu will throttle in some way.
  2. I noticed when flashing bios the fan is at very fast rpms, but when the gpu and cpu are on full load, the fan never reaches those rpms. Is it possible to mod this with bios?
  3. I tried SpeedFan, but the fan doesn't show up. Is it 7720 or 7720se?
  4. Can you explain which mount is higher (or point it in a picture). Because I have the same issue. I want to bring my Dell to the warranty technician and explain to him, so he could fix it for me. I could do it myself, but it would void the warranty. Thanks! edit: http://forum.notebookreview.com/dell-inspiron-dell-studio/690746-complet-photo-disamble-7720-a.html is this mount that you;re talking about? : https://dl.dropboxusercontent.com/u/27694046/img3292a.jpg
  5. Yesterday I bought Cooler Master U2 pad for my Dell 7720SE laptop, I positioned the fans directly under the laptop fan and I can say I see 3-4 degrees C improvement. However the 2 fans are noticeable, maybe I'll buy bigger and more silent fan to replace them...
  6. Is there gonna be modded A14 bios?
  7. Hello, I'm having a really hard time with this video card. The default GPU clock is 745mhz, it should boost to 835mhz. The problem is that it throttles down constantly. I read a thread, in which I found a way around the dynamic clock boost. So, now I can overclock the 650m manualy with nVidia Inspector. I tried to overclock the GPU to 1000, 900 and 800mhz, but in game, after 10 minutes it throttles down to 745mhz. And I can't overclock it back! I have to shut down the laptop and remove the charger. If I only restart Windows I can overclock the memory, but the GPU stays on 745mhz. The temps are normal, under heavy load they are 70-75. The OC is stable, on 1ghz GPU there're no artifacts or shutters. I found modded bios-ses for 660m and 680m, so can anybody edit the bios of 650m? I would upload the BIOS, but GPU-z says: Bios reading not suported on this device.
