Does anyone tries to unlock Asus ENGTX560ti448 to full ENGTX570, i.e - save to ENGTX560ti448 board of ENGTX570 Direct CUII/2DIS bios?
GPU-Z says that both have GF110 rev.A chip, not GF114 in GTX560Ti448 as in regular 560ti's.

These two boards from Asus with 3 slot Direct CUII/2DIS cooling looks nearly identical, only differs in used memory chips and soldered power connectors - 6+6 for ENGTX560ti448 and 6+8 for ENGTX570 Direct CUII/2DIS.

Device ID differs:
10DE-1087 for ENGTX560ti448 and 10DE-1086 for ENGTX570 Direct CUII/2DIS

Board ID's also differs:
1263-0010 for ENGTX560ti448 and 1263-0000 for ENGTX570 Direct CUII/2DIS.

But PCB's of both nearly the same with above mentioned exclusions.

In the past i have 9800GT TOP from Asus - it was rebranded reference G92 board 8800GTS512 with 128 processors already activated, not 112 processor as in 9800GT.

So, have a hope that in this case is possible to flash 560Ti448 to GTX570, maybe, with a bit of soldering of external configuration resistors.

There is a slim chance it is possible, both cards actually use the same amount of RAM, the sole difference between them is the number of shaders active on the GPU core. It might be possible to unlock those shaders by flashing a GTX570 BIOS to the GTX560448, however most nVidia cards are laser locked I believe. This means that there is little to no hope of having a card that is unlockable. There were rare exception where nVidia didn't laser lock the cores, but for the most part they are.

IIRC it is not possible to unlock the GTX560ti 448 cards. They are lazer locked.

You cards might use the same PCBs, but not the same GPU dies. If they were software disabled by the BIOS then you could unlock them, but these are lazer locked so its not possible.

I figured I would post it here since it is very similar, but is it possible to unlock the EVGA GeForce GTX 560Ti "448 Edition" FTW into a 570? It is just that my graphics card too has the GF110 rev.A chip and I really want to know if the option is available, and if all 560Ti "448 Edition" are lazer locked (just to not progress any further with more questions if that is the case).

I have not heard of any 560's ever unlocking to a 570.
