I think you should see your mainboard specification to select the best frequency RAM to use. Because if you buy 1600Mhz RAM but your mainboard support 1333Mhz, it will run at 1333Mhz. (Maximum of your motherboard) But i think it should work with your mainboard & processor.

TS made a special post about the SLI version. So if you have a SLI version you download the SLI version in every other case you download the OP version.

Thanks for your answer. I don't have an ultray bay, So i will try on OP version soon. : D

Is it support Y410P all model?

I have Y410P-59369482 and want to try it. Is it compatible?

Did you trying to boot with another OS like Ubuntu live CD to see hardware information? If it shows 750M i think it's only driver problem but if it's not shows i think it might be bricked : (
