Hello, I'm the new member in T|I.. I've flash my vbios to OC edition GTX780M vbios... using the 335.23 nvidia drivers (custom .inf).. as I push the value to more than +140 on core and +120 on memory, the screen will freezes and crash during benchmarks (early point of benchmark).. anyone know the problem? could this cause by the lack power? as I'm using the 180w stock PSU.. and moreover I can enable the hybrid power on my laptop but it doesn't help at all.. I was considering upgrading the PSU to 240W but do I need to flash a custom BIOS too? please help.. TQ~ Sustem information: MSi GT70 20D Dragon Edition 2 Processor i-7 4700M 8Gb Ram Nvidia GTX780M 4gb ram (unlocked vbios) stock BIOS overclocking software (nvidia inspector)

I'm using MSi GT70 20D with unlocked vBios (GTX780M card).. I've raised the value of core to +140 and memory +115.. it goes right without crash but the problem is I can't raise it more than that.. is there any advices? I'll be testing your driver soon (the 345.20 drivers).. FYI, I have stock BIOS.. and stock 180 PSU for my laptop.. really appreciate your advices in the future.. thanks a lot.

sorry.. there's a problem.. I didn't know what value to put on the core clock (mhz) and memory (mhz).. any experienced user? can share their oc? thanks in advance~

Finally manage to make it run.. thanks for everyone help..

many thanks.. I've download nvidia drivers from msi 311.91.. but still doesn't work.. looking for better answer from @J95 and @Mr.Fox.. Thanks again..

@Brian Thanks for your reply.. But when i try reinstall the drivers the setup say no hardware detected.. I'm using nvidia 335.23 drivers.. any idea why it didn't work out?

Need help.. I managed to update my vbios using the Nvidia GTX780M 'OC Edition'.rom that I download in the 1st page.. the process complete.. and when I boot to windows.. device manager detects my card as "Microsoft Basic Display Adapter"... anyone encounter this? I'm looking for a solution..
