NVIDIA does indeed use RAM chips with mis-matched capacities to achieve this.

Ok. I did a SLI guide and now time to do a vRAM/memory bandwidth guide. A lot of people seem to be confused about vRAM in general. Well, here we go.
 
Let's clear up some misconceptions about vRAM! 
 
 
What does vRAM size have to do with gaming?
 
 
Bonus: What happens if I don't have enough vRAM that a game asks for for certain settings?
 
 
And now resolution, Anti Aliasing and operating systems
 
 
And now about multiple monitors
 
 
Now, onto memory bandwidth and memory bus and such. You may wanna skip this if you know already and are only here for the vRAM size portion above, but I might as well be thorough if I'm doing this. Spoiler tags save the day!
 
vRAM types & memory clocks
 
 
Next, memory bus and memory bandwidth!
 
 
Extra: Memory bus + mismatched memory size section
 
 
And the GTX 970 gets its own section! Hooray!
 
 
FAQ
 
 
Windows 10 and nVidia 353.62
 
 
Final tidbits and stuff
 
 
I started writing this guy mainly for the top section, to denounce misinformation people seem to have regarding vRAM and its relation to memory bandwidth, but I figured I might as well just go the full mile and explain as best I can about what most people need to know about GPU memory anyway. If I've somehow screwed up somewhere, let me know. I probably have. I'll fix whatever I get wrong. And thank you to everyone who has contributed and corrected things I didn't get right! Unlike my SLI guide, much of the information here was confirmed post-writing.
 
If you want the SLI information or the mobile i7 CPU information guide, they're in my sig!
 
Moderator note: If you believe any information found in this guide is incorrect, please message me or D2ultima and we will investigate it, thank you. - Godlygamer23

Interesting strategy..
 
Anyways, he should be looking into replacing this platform for something newer. For example Ryzen 5 1600 AF or 3600 + 16GB of 3200-3600Mhz + a B450 board (like a Gaming Plus) would do good.

What specific PSU is that, by the way? EVGA B2, BQ, BR, etc.?
 
EDIT: oh and he should get an SSD too.
