Adding a second GPU
Adding a second GPU
Hi to all!
I have a little help to ask you guys, since I'm no hardware expert.
I'd like to add a second GPU to my recently-bought pc, which mounts:
CPU (Processor):Ryzen 7 1700X 8x 3.40GHz (YD170XBCAEWOF)
Mainboard:B350 MSI Tomahawk (7A36-002R)
Video Card (VGA Card):Zotac GeForce GTX 1070 Mini, 8GB GDDR5, DVI, HDMI, 3x DisplayPort (ZT-P10700G-10M)
I read that my motherboard doesn't support SLI, but it's "crossfire" ready.
Given the fact that i have no clue of what that means (...) would basically be useful to add my old GTX480 to get a little computing power for Indigo openCL?
Thank you a lot, and sorry for the (maybe) dumb question!
*EDIT* I found here some specs
https://www.zotac.com/us/product/graphi ... ini-0#spec
and seems like the new GPU DOEAS HAVE "SLI HB Bridge Supported"
*EDIT2* I found a post by ZomB saying that Indigo doesn't use SLi or Crossfire
So, basically, it's just connect the two f***ing videocards and play ahahahahah Am I right?

Re: Adding a second GPU
The GTX will probably be pretty useless for OpenCL rendering. But you're right, no need for SLI when rendering with Indigo.
Re: Adding a second GPU
hmm... they're both GTX ahahahahahah
i guess you meant the 480
Ok then I'll give that a try and I'll let you guys know!

Re: Adding a second GPU
I once share the same problem, but indigo itself had sorted out these issues.
Re: Adding a second GPU
Ok guys! I added the second video card (turned out to be a GTX950, and not a GTX480.....), and a second screen!
It's very cool!
I had to connect the second screen to the 950 because I haven't the right adaptor. Is there a way to monitor the contribute of each video card to the calculation?
Just to know if I have done something wrong!
Thanks you guys!

Re: Adding a second GPU
Hi Oscar J !
What do you mean with the useless GTX ? I already have a GTX Titan X and is been working pretty fine so far, so...am i missing something? Do you have any other better sugestions ?)
Curiosly i found this topic looking out for some info about adding a second video card to my pc , i want to know if is possible to use 2( or 3 ..or 4 ..etc) different GPUs, like 2 Nvida and 1 AMD or 2 Radeon and 1 Nvidia and so on, being all different models.
I am asking this because now i can not afford other Titan X but i need more power so, any other a cheaper GPU would be fine unless they get useless together
Re: Adding a second GPU
Lal-O: Mixing different kinds of GPUs works fine.
The only thing to watch out for is if one is way more powerful than the other you may lose some efficiency.

I meant the GTX480 that Pibuz was talking about.

Re: Adding a second GPU
Well, consider that the oldest Nvidia GPU in the benchmark is a GTX 560 and that provides about 5% of the performance of a 1080 Ti. OnoSendai just mentioned that you lose efficiency with GPUs that don’t have roughly matching performance, which could actually result in a net loss of performance. Then there’s the issue of 250 W power consumption and how much heat the GTX 480 will generate. Is it worth it? And that’s before even taking into account the huge bottleneck that is 1,5 GB of GPU memory, which will prevent rendering of anything remotely texture- or geometry heavy.
In essence, probably more or less useless.

Definitely is useless
So, i finally decided the second gpu for my pc and i went for the 1070 Ti, i can not wait to see how it works with my Titan X. I hope it worth it
