Nice, Good job! Cool  MSI P104-100 works steady 42.8 MH/s. No improvement in speed as before.

Does anyone know, how is it possible to unlock 2560 CUDA cores?

I found this information, that someone wrote:

- 8GB of GDDR5X of which half are disabled via BIOS

- PCI-E 1.1 X4 enforced with BIOS, true hardware form PCI-E 3.0 X16

- Display engine is disabled with BIOS, the I / O ports are actually mechanically functional

- 1920 CUDA cores instead of the default 2560  (possibly all 2560 on board)


Thanks darkneorus!


Hello,

 What driver version did you use?
