First of all, check the number on GPU, if it’s GF100-275-A3. That means you can unlock GTX 465 and become a real GTX 470.
If you are a lucky guy, and then let’s go to the next step. Have a bootable USB drive with nvflash tool and unlock BIOS.
Type “NVflash -9” to erase the BIOS information. Remember, this step is really important, without this step, the unlock BIOS will not be fully written into the BIOS chip later.
Now you can flash the unlock BIOS into the BIOS chip. Type “NVflash -4 -5 -6 470_448.rom” then type y to confirm.
Wait about 1 minute and system will ask you to reset. Now we will see the final performance!
The original GTX 465, Score is 8981.
The GTX 465 with unlocked GTX 470 BIOS, Score is 10424.
If the unlocked GTX 470 BIOS is not stable on your card, you can try another unlocked GTX 465 BIOS (BIOS name: 465_448.ROM). Performance will be between GTX 470 and GTX 465, because Shader number will be 448 units!
Here is a very simple performance comparison.
In the end, I still need to remind you guys that although it’s cool to get “extra” performance for free, do it at your own risk.
