GTX1080 SLI - memory usage @ 4Gb?

[faxfan]

I've got 2 x 1080 in SLI mode and the memory usage on both cards seems to be a static 4Gb with no changes. I'd have thought it should have been 8Gb?

I suspect there is a hidden reading I'm not seeing and it's nothing to worry about but it peaked my interest.

What app are you using to measure the VRAM usage?

 

[faxfan]

MSI afterburner and hwinfo is giving the same info - this is "used" vram. GPU-Z is reporting the correct total vram but when I go into SLI mode and look at the sensors it's a minus figure. Hence checking on other applications.

what games are you playing?

I think 4064MB is the limit for dx9 games. Might be relevant somewhere?

Not playing any games, as soon as I enable SLI the memory allocation on both cards goes to 4Gb and stays there. Actually looking at MSI AB the memory usage on each card says "41919" MB which says to me 41GB... very weird.

I have seen people complaining on other forums about this. It's confirmed as a bug in how the VRAM is being reported.. though the exact reason seems to be unknown
