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.
The VRAM I used can be purchased here: www.aliexpress...

Buddy 2020&2021 that would be something that i was consider I had r7 250x 1gb gpu , and that was issue with come games like Fallout 4 , and with ridiculus prices in GPU where I was living 1030 2000kr (200$)... used , a card that are not as good to pay 3 times that gpu was worth before covid , so spending some cash to upgrate ram in covid is literally worth it , sadly ... or great now GPU's are back to normal prices and I have bough r9 390 8gb for 800kr (80$) week ago , and I am happy with that , but still perspective of ram upgrate is tempting , not with r9 , but when I looked for gpu and there where number of cheap GTX 1060 with 3gb ram , and upgrate for 6gb might be option for some .

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.

[@tibib0ss]

Thats not how graphics cards work, You can have a 200GB card from 2000, it wont run faster than a 8GB card from 2021. due to the limitations of architecture they used back then

Nice video as always! Also, do you know why graphics cards can't automatically detect the installed memory? I was looking into upgrading vram on existing cards a week ago and it's funny how you upload this a short time later

[@dosdude1]

The VRAM amount is set by the VBIOS. If there is a VBIOS available for a card with a higher VRAM amount, then you can upgrade the VRAM on that card and flash the respective VBIOS.

[@MLGPRO-dx8fg]

@@dosdude1 Do you know why a graphics card can't detect memory in the same way a motherboard can? Does this functionality cost enough for OEMS to just hardcode the VRAM capacity in the bios of their cards?

[@dosdude1]

@@MLGPRO-dx8fg Removable memory modules have what are called SPD EEPROMs on them, which have data on them that tell the machine what characteristics are of the memory on that module. On machines/boards with non-upgradeable memory, there is no need for this, and the memory characteristics are hard coded in the device's BIOS.

[@MLGPRO-dx8fg]

@@dosdude1 Thank you very much. I am getting into working on electronics physically and not just writing software so this helps a lot.

Would be cool if that would be possibile with the current nvidia 4000 Series, they are lacking a huge deal of vram. Maybe even chat-gpt like programs are able to write bios versions, so it matches the amount of ram you want to install.

[@Respectfully10]

Your main objective should be getting the exact RAM/memory chips

[@billnorman7894]

​@@Respectfully10Some stores actually do sell GDDR6 memory but not sure on GDDR6x

[@RianRussill]

@@billnorman7894 They already do on Tao Bao or otherwise. most of these chips however are recovered from GPUs that have died in one way or another. most of the GDDR you see on the market is essentially the same- either harvested from corporate GPUS and Skus for use in lower density cards, or salvaged from broken cards and tested for consideration and sold.

[@RianRussill]

@@Respectfully10 Exact RAM/Memory chips are a myth- most come in different bins, what matters more is the simple factor that they are all the same RAM type/Sku. Most card autodetect these expanded memories easily, but the BIOS refuses to address them due to either non-consideration for the SKU or simple software locking.

One genuine question as I’m gonna be modding a lot of GPUs, is it possible to mod any GPU from its original vram models to almost any amount for example? Gtx 660ti - modded 8gb vram 560ti - modded 4GB vram Gtx 750ti - 6GB vram so on and so on Not like for some GPUs which already have another model of the same GPU with extra like Gtx 760 2GB / 4GB vram Which would be like this mod shown in the video I’m trynna reuse some older GPUs to hold up in newer titles if it wasn’t for vram constraints
