Okay.... so what vbios (etc) is johnksss using for his 880m overclocking?

Ah... nevermind... just got a response from johnksss on a different forum. Completely unreleased as of yet... will be waiting.

At the very least you'd have to make sure that the amount of GB of VRAM was the same between your 880M and the 780M vBIOS that you were going to flash. You also might lose Optimus graphics switching if the 780M wasn't a selectable option for your build of laptop. I don't know enough about it to give you a definitive answer about whether it would work or not, but I know you would want to consider the previous 2 points I made anyway.

Flashing an nVidia GTX 880m... is it ok to use the GTX 780m - 'OC edition' - rev02.zip in Post #2 ?

I've been reading these forums and some related articles with great interest, as I have just gotten a new rig with the new nVidia GTX 880m.

I must admit that I probably would have just gotten the 780m, with the lower memory, had I performed the correct searches earlier on.... but hell, the last time I was gaming, Battlefield 2 was the rage, and WoW was just becoming a mild social concern... and besides, I keep hearing the faint echo of "640K ought to be enough for anybody"... (anybody... anybody... anybody...) Plus, after suffering a concussion a few years ago, my own memory isn't the best sometimes... so now as it begins to fail me more, I'll take comfort that my graphics card has more than enough to spare for both of us.

So... back to my question... can I flash the 880m with the 780m vbios, or should I wait for an 880m-specific one?

After reading everything I can find, it seems like I should be able to use the GTX 780m vbios for my 880m, since they're essentially the same card... but I haven't read anything that explicitly states that. I'm uncertain whether the difference in the amount of memory would warrant changes to the vbios file, or if the same vbios file is all good, and the processor just uses whatever memory it has available. I even read an account of overclocking the 880m specifically, but there was no specific mention of what vbios was used.

Could someone clarify for me? I know I could just do a backup of the old vbios first, and restore it if something goes wrong, but obviously I'd rather avoid it if possible.

Thanks!
