Pagefile/Memory error.

To start off with my Computer specs are as follows:

Intel i7-4790k at 4.4 ghz. 

nVidia gtx 780 3gb.

8 GB of G.SKILL Ripjaws ram. (not the most, I know). 

OS: Windows 10.

The rest of my specs meet above the requirements, as well as the aforementioned. 

The problem doesn't really lie upon that of a graphics issue, or a processor issue - to my knowledge. My rig isn't the greatest, however I've seen plenty of people run worse setups than mine just fine, including my Girlfriend who is able to run it off her rather mediocre laptop without issue. (Same amount of Ram too)

After countless hours of research and reproducing the problem, it seems that the issue is that of my Pagefile. After roughly 10-20 minutes of gameplay, my game starts to stutter something horrible. After a quick Google search other people too were experiencing this problem, something to do with the Pagefile and memory leak errors to do with GTA V itself, not necessarily the person in question. People recommended turning off Pagefile entirely. To my surprise this worked, it removed the stutters and the game ran smooth as a baby's butt. However after about 1-3 hours of gameplay Windows would popup a window explaining that of a memory issue and that it needed to close down certain tasks inherently this crashed GTA V as that was really the only task running. 

It's not necessarily a problem that I have to restart my game after hours of solid gameplay, it's just the fact that I can't for the life of me track down and fix the issue as whole and that GTA V is the ONLY game that sucks the life out of my Computer, literally. I'm not overly tech savvy, but on the other hand my inner geek just makes me cringe and want to fix the problem. 

After more research, other people on a global level for Computers were saying to manually set the Pagefile, (the most typical one I saw was setting it 1.5x the size of your overall ram), roughly 12gb of manually set pagefile, which to me seems odd and ridiculous. So far I've tested 4gb of pagefile, to no luck - so now I'm currently testing 8gb, my actual ram size. Prior to setting any Pagefile or even knowing about it I monitored what GTA V was using for resources, it slowly but surely hogged up most of my memory and then some, which causes the stuttering issues. Further research showed that other people reported that GTA V was using nearly 15 gb of memory. 

I've for the most part segregated the problem to being just that of my Pagefile, or lackthereof, as the game runs buttery smooth if I remove it, but at the same time I shouldn't have to remove certain aspects of my Computer just to run GTA V smoothly. It's driving me bonkers and if it IS a memory leak on GTA V's part, what would be the best way to combat it? Is driving up the pagefile size to 10-20gb the only viable solution? Also, reducing the game to Minecraft graphics doesn't solve the problem either, it doesn't seem to matter what the settings are at, it just seems like GTA V enjoys gnawing on Ram. 

Any help would be greatly appreciated, or at the very least some brainstorming.
