grifos

Hello there. I am a newbie to this forum and to the whole egpu project . For days now I am reading several topics on this subject and watching several youtube videos too. I own a 17" Lenovo G710 laptop OS win.10 / i7 HQ 4th generation / 500 gb ssd / 16 gb ram / nvidia 820m 2gb. My question is 1) is there anyone who has installed egpu to a laptop same as mine ? (Via mPCIe) 2) which gpu do you prefer v8 beast or PE4C v3.0 3) I have watched that some guys have problems with "whitelist" at bios. How can I check if my bios are "locked" and is there anyone easy way to "unlock" them ? 4) is there any limit on what graphic card can i use ? These are my very first questions . I will be happy receiving answers from you guys. Thanks in advance.
