PC not using full VRAM

[Drayton_1]

Just recently I noticed that my PC is only showing that I have 1536mb of VRAM, I have a GTX 760 2gb installed.

I have no clue what the problem is, it just seems like 512mb disappeared...

Please help me get them back. here are some screenshots to show you what I am seeing.

First off, did you check this before and it said 2gb and now you checked it again and it says 1536mb? Or are you just assuming it would have said 2gb before?

Have you tried a program like MSI Afterburner, so you can see what it says is your vram total and how much is in use while you run a game?

I would agree with the above... Are you certain it is a 2GB variant? There were OEM GTX 760s that went into machines that had a lower memory bandwidth + lower amount of VRAM than the reference cards.

Ok, I was looking and could not find any 1.5gb until now. Now i'm not sure but i guess i have always assumed it was a 2gb. This graphics card come straight out of an Alienware x51.. would that be the 1.5 card?

I will be honest that I do not have the foggiest idea which companies put them in machines and what else was going on with them. However I can tell you that if you've never overclocked the card, the core clock could also help identify that as the oem was clocked slightly lower.

I Have no clue what you just said. the core clock, and the oem. But thank you for helping.

Download gpu-z. It can give you information about gpu.

Why downvote the answer? That answer is entirely pertinent. If you were to download GPU-Z, you would be able to get information in regards to your GPU. If you were also to download MSI Afterburner, you could see some of the information in regards to your GPU as well.

If you are not willing to do either of those, I'm going to say you likely have an OEM version of the GPU, and not a commercial version of the GPU.

Alienware did use the 1.5 GB GTX 760s, a weaker GPU with less memory bandwidth as well, in their x51s.

I would be surprised if this wasn't the 192-bit variant that had 1.5 GB of VRAM. I've never liked Nvidia's tendency to making weaker GPUs, even for OEM, without it being obvious in the model number. See the GTX 460 768 and GTX 460 SE vs. a regular GTX 460 and the 1060 3 GB vs. the 1060 6 GB.
