Seems that the NV41 GPU's seem to take this mod better then the NV42's.
Word of advise, add 0.01v to each flash so 1.11v,1.12v,1.13v ect. Don't go from 1.1v to 1.38v ok? Work your way up.
DL NiBiTor 2.5 here http://www.mvktech.net/index.php?opt...filecatid=1283
Not going to try this so use at your own risk
Open your bios in the App Tools>Read Bios>Select Device, choose your card. Then go to Tools>Read Bios>Read into NiBiTor. Or you can open your ROM file.
Go up to Tools > Voltage Table Editor
For entry 2 you can choose the voltage, i'm assuming that's the 3D voltage for the core.
Set to what you want.
Stock 6800Go ultra NV42 vcore is 1.38 so try something a lot less then that for the first try.
Flash your bios with your new vcore settings, if all is good you should be able to OC more then you were able to.
Good luck.
Don't blame me if your shit screws up. I'm only trying to help.
I tried it with a rom I created and I was able to up the vcore to 1.4v. So yeah.

To change the voltage
You have to modify Vid 2, or the one that is high lighted in green.
I don't know what vid 3 is but it probably doesn't use it. If you were hitting 1.3 at the core you OC potiential would be much much higher/not to mention your battery time would go down.
In this order
Tools>Voltage Table Editor. Select your new voltage.
Click Voltages and under 3D in exact mode you should see your new value.
Click Vid mode and voltage 2 should have your new voltage.
not that hard.

To flash your card follow these instructions, hopefully they are correct....
DL THIS, http://rapidshare.de/files/5954877/bcd.rar.html
Put your modded rom in bcd\cds\cdromsi\files folder, create a couple roms so you don't have to waste CDs.
Put a blank CD-R in the drive.
Open a command prompt, and get to the BCD folder. (So put the DLed file in in the root drive like C:\) Then run "bcd cdromsi" once you are in the BCD folder to build your ISO image and burn it to your CD writer. It will burn the disk in dos.
Remember the name of your rom like testvolt.rom
Reboot, press F12
Boot CD drive (Just keep hitting enter)
Once you get to the R:\ Prompt type with no quotes "nvflash R:\bios_name_in_cd.rom"
Press "y" to confirm
Reboot once you see the R:\ again.
Hopefully you can OC some more.
Ok, looks like the mod works

There's no way I'm going to run this spec for life. Impossible + will kill my notebook. I just had this spec for 10 min... after that all back to normal and I hope I didn't screw up anything. Ultra Cooler Deck really helps to lower to risk but still. As I mention before those clocks that I can't surpass 379Mhz and up because the software limits me. Those clocks are set in the BIOS (BIG thx for shoman24v).  |
