Double your GPU Memory 2080TI 22GB V-ram

Hey everyone, well i thought to share as there was a bit of interest in another thread on here so why not.


You can double the ram on certain Nvidia GPU's

Namely the 2080ti
3070/3070ti and
3080

I have pretty good information on how to do a 2080ti so thought to share the information i have. However, i don't have the ram chips or the tools myself to do it, so it's something i'll do at a later stage.


Anything you do to your own card is at your own risk, so be careful, and doing any of this will void any warranty.


There's a video and read up on it here.

HOW TO DETERMIN IF A CARD SUPPORT MORE VRAM
1. The GPU must has a NVIDIA vBIOS that some how* support bigger capacity memories.
2. The POINT MAP and CIRCUIT MAP must be ready for this particularly card**.
3. There must be a suitable memory chip available for the card.
*:Option 1:The card is using 8Gbit chips but there is support for 16Gbit chips in NVIDIA vBIOS(example:3070 16GB,2080Ti 22GB 3090 48GB)
Option 2:There is empty solder point in the back of PCB(example: 3080 20GB 3070Ti 16GB)
**:Every different card design have a different POINT MAP and CIRCUIT MAP.Must be found.
PARTS NEEDED
1. New memory chips(GDDR6 16Gbit:SAMSUNG K4ZAF325BM-HC14)
2. Point maps
3. Circuit maps
4. Professional for PCB soldering.
5. Software:Boardview.exe




So pretty much, check out your own card's Bios for what memory settings are available, find online the board map ( if not reference, as there's one available for reference ) and adjust the 3 strap settings manually with resistors.

Along with soldering in the new ram chips on the card.

 

i can hear the coomers upgrading their vram for more stable diffusions lul
Someone in that ltt thread said 4000 series doesnt have memory doubling? Oh great another feature lost i guess 2000-3000 series will age better than 4000+ crap with skimped vram
remember when they wanted 3000usd+ for a rtx titan with 24gb? 5 years later the 4090 tops out at 24gb what a joke brooooooooo

 

Did you happen to do any before and after benchmarks with VRAM usage?

 

Oh, this isn't my card. Just sharing information.

I will get some ram chips and do the mod, just need the time, and probably a nice long wait for the chips to get here from overseas.

 

Pretty cool stuff, but completely pointless on a 2080Ti right? For gaming anyway.

Still a fun project no doubt.

 

nah, not pointless.


You can i guess have more crypto mining output per card

also, you can turn the textures up to max where as on a 3070/3080 ect: you can't on some games without stuttering and texture loss/flush as it has to refill the ram.

 

Yeah it wont be pointless on ue5



On current games probably until we get bigger textures

 

Biggest issue who does surface bga work and how much wanna put an i7 in the MacBook Air lol but if it’s over $100 not worth it

 

Note I only questioned the point of it for gaming, given the 2080Ti already has 11GB and it's only at a 3070 level in raw performance. Other than a few titles which were patched quickly, the only way I could get my 3070 to start hitting vram wall was at settings that were undesirable at <40fps anyway etc.

That video comparing the 2080Ti to Titan RTX at 4K max didn't highlight anything did it? Both avg and 1% lows were just sometimes marginally better over the 2080Ti. And that's not cos of 24GB vram, it's cos of the 4608 vs 4352 cuda cores.

Pls don't let me stop you - I'd love to see you do it!

 

Lol the 3060 and 4060 16gb are even more useless for gaming but thats not the point this will be fantastic for sd and other vram intensive stuff.
I still think textures will get larger enough in combo with rt and pt and upscaling tech as well as interpretation thats all vram heavy

 

So I download 2080Ti_Double_Ram.exe and ran as Administrator like they told me on Telegram but now I can’t log into windows. Did I do something wrong?

might of got the straps wrong, or needs the titan bios to "unlock" that much vram.

hopefully the 22gb mod doesnt have that problem

 

Looks like it's because they didn't do the strap as well.... So the card was like " wtf did you do to me, it's not what i'm expecting from the strap "

the strap is set up for different brands of ram and densities.

the max is 22gb as per the strap abilities to see 22gb.

 

if the bios wasnt signed and enforced, id do a compare of the two, find the straps, and see what extra is directly after in the titan, then insert it into the normal one and flash away.

Im amazed no-one has bothered to crack the keys already, how will they sell knockoffs/rebadged units on wish/alliexpress/alibaba without it? LOL

 

Just throught it was interesting i wonder if the titan rtx can have its vram doubled. Always wanted one od those but impossible to find

 

That binary only works when you are on a flat planet .

 

Flat erf!

There you go, someone in Australia's done it.

 

Very interesting.

Found these on ebay
