Hi everyone, I am an Alienware 18 owner, my laptop has 2 GTX 780Ms in SLI, 32GB RAM and an i7 processor. My cards are starting to be a little on the underwhelming side now, they run my HTC vivr fine for most things but my AW18 could do with an upgrade. I would like to upgrade to the 980Ms in SLI. I have upgraded my BIOS to A13 from A03 (although now I understand the BIOS has to be unlocked to swap cards?), I have been looking GTX980Ms on ebay and eurocom, i have the right heatsyncs (the ones with my 780ms) but I cannot source the Prema Mod vBIOS anywhere, I've been all over every site these guys have and have come up short. Please could any of you guys give me some help to accomplish this mod please? questions: 1. Does anyone have any updated links or have the vBIOS package still on their computer I could have 2. could anyone give me an update for 2018, such as BIOS issues, fan, heatsync issues etc or if these have been rectified 3. Does anyone know if i can use the SLI cable going between my 780Ms for SLI with the 980ms 4.I keep finding 2nd hand cards on ebay with g-sync, what does that mean 5. Does anyone know an alternative vBios if I can't get hold of the Prima one 6. What is the differnce betweek a locked and an unlocked bios, where can i get an unlocked bios and why can't I jsut swap the cards out for the new ones on a stock BIOS downloaded from Dell thank you, I really appreciate any help people can give me.
