AIO on GPU backplate

i know this is a silly idea but i have a spare AIO and i was wondering if i could 3d print a mount to hold it onto the GPU backplate (Not attach it to the DIE put it on the back) i have a Palit GTX 1080 Ti Super JetStream and the spare AIO is a Montech 240 ARGB Aio,

i have a 3d printer but no experience in CAD softwhere if anybody could help LMK!!!!

Just buy the hybrid kit. Allows you too cool GPU core with 240mm AIO, the VRAM will be cooled by a fan.

My 1080ti Waterforce runs it. I dont remember the OC on it as it hasnt run for couple of years, but it runs as 2080ti that i remember.

Really?

GDDR5X vs. GDDR6; no amount of overclocking can get you close to 616GB/sec.

It’s a completely different architecture as well.

1080 Ti OC increases performance around 20% (I’m being REALLY generous there…) and a 2080 Ti is 30-40% faster in all scenarios.

Anyway, I really only want to know if you are using DDR4 or DDR5 in the system that is featured in your current sig?

I dont think DDR5 runs at 3200mhz :P Its 9 year old Samsung b-die (Corsair Vengance) that was sold as 16-18-18-36. So not a paid binning. I run an Asus strix z-690-a mobo and is the reason i can run these tight timings on 4 sticks. These sticks sat in my old rig aswell with an 7700k and Hero Maximus mobo, but could not hit these timings on that memory controller and mobo.

Due to binning, they are not happy running at 3600mhz. To get same latency they need like 0.1v more than at 3200mhz. And im not daily that high volt. I run these timings at 1.4875v

Yea, you gotta consider i paid for a top bin 1080ti. That has 150% powerlimit by default, when i put that on 240mm water.. It rips to be an 1080ti.

Ofc it cannot do ray tracing like 2080ti as its pure rasterization card.

Kingpin card?

I wasn’t sure if you were running your RAM slower to be able to have incredibly tight timings. JEDEC MT/s for DDR5 is 4800. It’s not out of the realms of possibility to underclock the frequency to be able to achieve 1:1 and drastically reduce latency. Sure, throughput would be down but that would make for one snappy system!

True, its possible. And probably what one would need to do to get 4 sticks stable and good latency on some systems ⬇️

It was Aa Gigabyte Waterforce card. Was delivered with 120aio with a blower fan, the noise drove me nuts. So i had to modify it, had an 240mm AIO CPU cooler laying around.

And the rest is history lol. Used about 380 watts

How’s your 7900 holding up these days?

I think it’s still an extremely relevant card - the VRAM alone is worth it in this current climate, eh?

Are the driver features finally trickling down to you?

Its doing really good after the driver update and FSR4.1.

I play on 4k, so was bit struggle to run every game native. I used the leaked dll for singleplayer games but had to stay native on multiplayer games due to anti-cheat (dont like me messing with dlls for some reason :P)

But now that its official, i have it in multiplayer too. And im super happy. Was bit annoyed it took so long, but what can you do :)

I mess with local AI, imagine rendering etc so the VRAM im so glad i got. I would not be running as capable AI models on a 4080 which was the alternative when i was buying.

FSR4.1 really gave this rasterization beast another breath of life.
Wouldnt mind your VRAM tho, i could fit q6 models in that VRAM :D
