1. No vendor would ever roll out a BIOS outside of the absolute necessary

2. If they did you'd be left with a brick, because NVIDIA has almost always disabled SMs via laser removal

I see many articles on different sites claiming "Nvidia corrects 970 specs" (Like anadtech, PCpr, guru3d) but I do not find an official source of this?

Edit:
I am asking because my reseller (Agito.pl) states that Nvidia have never changed the specs on this card.

He probably talks about split frame rendering (SFR) in SLI/crossfire where memory doesn't need to be identical in both cards. Each GPU only needs memory to be able to render its part of the frame.

GoldenTiger was doing a lot of benches over at Nvidia-forums aswell. PcPer just did a SLI-review. Some games use more vram than others, and thus give different results. The FC4-video from ComputerBase (above) shows just how bad it CAN get. Warning: Spoiler! (Click to show)

Thanks. I saw the images but couldn't find the post.

SFR uses sub GPUs as slaves thus performance scaling isn't great but frame times are noticeably improved, as well as potential to stack available video memory. There is a reason games do not use this method though besides CIV BE.

AFR is still the most preferable method, and what Thracks is saying is nothing new. He's just rocking the boat.

AFR is only the most preferable because it gives the largest scaling and best frame rate numbers. This frequently does not translate into the best experience.

I'd gladly sacrifice a fair amount of scaling for improvements to latency and frame time consistency...which is essentially what I've been doing since I dumped my SLI and CFX configs for single GPU setups.

Tell that to AMD who are pro-actively promoting UHD resolutions and SFR simultaneously lol. Johan Andersson who was lead programmer on Frostbite 3.0 / Battlefield 4 has said AFR is still the method of choice.

There is a future for SFR, but it's not got much of one within the next two years IMO
