Unlocking Zotac Gtx465 into Gtx470
I want to unlock my zotac gtx 465 graphics card. It has 10 memory and unlocking is possibble.
I downloaded gtx470 bios from in here. http://www.mvktech.net/component/opt...einfo/id,3227/ I updated its bios successfully. But Still My operating system knows my graphics card as gtx465. I am using Windows 8. What is the reason of this ? |

Try a BIOS from TPU's BIOS collection, perhaps?
Be aware that flashing a graphics card can brick it unrecoverably, before you try another flash.

What did you do exactly? Just flashing the bios on your GTX 465? Are you sure you have an unlockable GTX 465? If I remember it correctly there are some steps that needed to be done first before you can turn the card into a GTX 470. I am not sure, but I thought that erasing the EEPROM entirely (via some command from nvflash) before flashing the modified bios is one of the requirements, and that's a very dangerous thing to do, since if something goes wrong during the bios flash then the videocard will be bricked/dead. |

Correct, you have to wipe the EEPROM completely before reflashing.
So before you do the flash you have to run nvflash --eraseeeprom. Then when you flash the bios you have to use nvflash -4 -5 -6 gtx470.rom.

I dont have very much hardware information. Just I read somethings about unlocking in somewhere. Such as, if it has 10 memory, it can be unlocked. So I am not sure exactly.
I tried below. 1. download bios gtx470 and boot system. 2. nvflash --eraseeeprom 3. nvflash -4 -5 -6 gtx470.rom 4. restart computer While I was doing these, I didnt meet any problem. |
