Upgrading VRAM on an nVidia GeForce GT640 GPU

In this video, I go over the process of upgrading the VRAM, or video memory, on an nVidia GeForce GT640 GPU in order to support a Mac-compatible ROM. The only Mac ROM I had available was one designed for a GT640 with 2GB of VRAM, so the best option was to just upgrade the VRAM on this GPU to properly support the ROM.

Every upload from you feels like a Christmas present. Regardless of time of year.

I did it in the less complicated way. My uncle had the 1GB GT640. I have simply sold it for 40$ and bought Quadro K620 2GB for 40 bucks :D

All the performance of the infamous GT710 but 10 times the effort! ;-)
Seriously, though, this looks like a pretty good exercise project for people wanting to learn BGA hot air rework, etc. Thanks for the vid.

I once made an GTX 1060 8GB, With an hacked 1070 bios. Works just fine ! Used 2 Vram chips from another (dead) 1060 6Gb card. It's always good to keep "dead" GPU's around !

This is awesome, been thinking if I can upgrade the RAM and/or VRAM on my 15"MBP2012retina and I figured I'd have to do a similar process. I would first need the proper equipment and some experience with the process and would start with something like this project first. So this was super informative, thanks!

THE MAN IS BACK (yet again lol) also Cool VRAM upgrade

Great Job Collin Super Upgrade Did Not Know You Could Do That On The Xserve. Can't Waite For You To Get My G3 to G4 Conversion Board Back Great Video Sir

[rupertanderson]

Really excellent walkthrough! I really appreciate the step by step nature, very helpful. Thanks and well done! 👍

these Kind of Videos need more Likes on how many people Watched, allot of people Curious not everyone appreciate the work

This is a very good argument for why GPU memory should be modular. Old capable cards could still be useful today with a small memory upgrade.

[goclunker]

You can also edit the gpu bios/efi file. Back in the day, there were many files floating around, pre modded.

Also, i am pretty sure I flashed a pci 6200fx with 256mb of vram with a pci-e rom and it worked perfect (not sure if the memory was a match)

Great job tho, its now a much better upgrade

Great video! Just want to mention the VRAM used in the video is DDR3 not GDDR3, they are different

[Filmproplus]

Holy shit.... this is super highly technical

[giannirusso]

Sup DOS been a long time and have gotten an alert from keep it up bro

[vytautaskleiza]

Even though you said "It's not worth doing it on most cards", I'd love to see the same concept be used on a more modern GPU.

[jozsefizsak]

That was fascinating as well as informative.

Nice job, nice video, thanks for your knowledge.
