VRAM amount got lower ?

[Zucbervskie]

In about three months or so..I've changed my OS back to Windows 8.1, but all of the sudden, Arkham Knight (yep I know it's a poor port :3 ) started to read my VRAM 1999MB instead of 2024MB (I've a GTX 760)...I didn't think it was that big of a deal until two months ago,it became 1984 for some reason...I didn't bother and thought it was a glitch or something in the game, but then, a week ago...I reinstalled my GPU drivers as it crashed alot (the one before the lates as of 25/9/2016), disabled the internal gpu from the bios (I thought I already did, lol)...and the VRAM became 1974 in-game ! I reinstalled Assassin's Creed Snydicate and it reads the same for some reason ! The weird thing is...GeForce Experience reads the VRAM as it is (2024MB) !

I would want to know if anyone else had that problem before...I'm already planning on switching back to Windows 10 for other reasons...but does 8.1 do that or is it just mine ? Or should I just perform a clean installation ? Or does disabling the internal gpu has something to do with it ?

EDIT : the vram was 2048...for some reason I was saying 2024 :3

Did you install the 32 bit version of Windows 8.1?

No, I didn't. I've 8GB of ram & they're used

Doesn't really matter what a game says... long as your OS reports it correctly.
Which you can see that in NVIDIA Control Panel > Help > System Info > Dedicated VRAM

Actually given the amounts I expect one of your memory chips on your card is failing as each segment dies you lose 25mb now eventually it might stop but it could continue until your video card fails entirely.

This kind of degradation is common in newer devices where itnwas decided to be better to disable a small module then just die immediately. Most RAM chips even have some redundant RAM modules specifically to take over for dead ones.

It generally would not work like that. If your vram is failing the whole chip will fail, which generally are approx 512mb each on a gpu such as that one. Plus when vram fails it would show visual signs via visual corruption, discolors, etc...

Visual corruption happened once, everything was all messed up, but reinstalled the drivers & it returned to normal.

Now I'm starting to get scared ._.

It still reads 2048 (For some reason I was saying 2024 in the original post :3 )

GTX 760 is old, but should still be under warranty, if further issues arise with regards to visual corruption (odd lines across your screen, picture discolored) during normal OS Desktop usage, then I would RMA the GPU back to the manufacture.

Yes 2048MB is 2GB

Here are some tests you can try to test for GPU VRAM errors:
