I bet u using windows 8.1.
In win 8.1 u must update the 2nd card bios to work properly, and if u need oc the 2nd card u must search updated and unlocked oc bios for the ultrabay card.
Someone in this thread posted a bios.
Yes, I have 8.1
I will search the bios you refer to and see if it works.
Thank you for the advice

Hello everybody; I Have a Lenovo Y400 650m SLI with modded bios 2.04 from svl7. Everthing was working fine until I update to the new nvidia driver (from 332.21 to 334.89). First, the second 650m was not detected (it appeared in device manager but it wont work). I solved this by applying the Y400Y500_GT650M_2ndVGA_update V3 bios from lenovo. The second card was available then, but was locked (no OC beyond the 135 mhz limit) so i flashed again the second 650m to allow OC past 135 mhz again, but once i did that the second videocard wasnt working again. I ended up restoring the system to a previous point (to nvidia driver 332.21) and everything is working just fine. Any one else tried the nvidia driver 334.89? Did you had any problems with the 650m SLI configuration and the modded bios 2.04? Thank you in advance for the comments and best regards!
