Does the 3090 TI support ECC?

[cleric_warlock]

The information online that I’m seeing about this is ambiguous and I’m hoping for clarification. If you know one way or the other, please provide a source.

It does not have ECC memory. It does work in a computer with ECC memory.

A GPU doesn't really "support" a memory type, it uses it.
The 3090Ti uses GDDR6X VRAM, you'd need professional grade cards like the A6000 which has GDDR6 ECC VRAM chips

 

(I literally had to submit a feedback to Google's inaccurate summary box thing about this)

GPUs have their own form of error correcting that's different from normal DRAM ECC.

You're seeing ambiguous results because your question is ambiguous. 'Can my GPU support ECC?' is a really strange question because your GPU has no real say on what memory you can install into your system, but also your GPU has a system in place to deal with memory errors.

I asked this question when I wasn’t home and didn’t have a chance to turn my main pc on to actually check my 3090 TI. GPU-Z reports that it does have ECC and there’s an option to enable it in nvidia control panel - is there some caveat that I’m missing here?

no clue
Why are you wondering? Just curiosity or are you trying to do something that requires ECC?

 

No real caveat, apparently I'm just wrong

Yeah, i’m putting together a threadripper 7975wx engineering workstation/server and i’m after good ecc capability for finite element analysis in particular. I was planning to use the 3090 ti in my current gaming build for this workstation/server after i get a 5090 for a new gaming pc and i was wondering if my 3090ti would be the weak link of ecc in my new system, but i guess not.  Workstation gpus are obscenely expensive and it’s good to know I can wait until i have a good business case for upgrading the gpu without compromising the reliability of my system.

Very cool!
Honestly, I'm unsure of how important ECC is in GPUs for that stuff. But if it's mission critical, yes, some 3090TIs have ECC, including yours. Wildly.
