[solved] Need advice on DAZ3D + 2 GPU Setup - RTX 2060 + RTX 3060

edited October 2022 in Daz Studio Discussion

I'm planning to use my old GPU with the new one.

RTX 2060 + RTX 3060

I have PSU 650 W Bronze. I don't have budget to replace PSU. So I wonder will it be enough, before I bought GPU riser. 

I've been calculating

RTX 2060 > 160W
RTX 3060 > 170W
Ryzen 5 3400g > 65 W

So in total, it's 395 W
In theory there's should be plenty room for other components like HDD, SDD, memory and fans. which should be in smaller wattage

Is there anyone has similar setup?

How DAZ3d Working with multiple GPU, will it uses both GPU's cuda in viewport and render?
I have read in this forum, like if the scene size only fit in one of GPUs, it will only use that GPU. Is it true?

    Recommended PSU size for the 3060 alone is 650W, I would not install the second GPU.

    The scene must fit both GPU's in order for DS to use them in Iray rendering, if you have the 6GB version of the 2060, it will be of little use = Another point against installing them both.

    Anyways, the 3060 is still pretty fast by itself. I have one and usually it takes around 15-20 minutes to render an interior scene with 2-3 figures. One figure alone renders in 5-10 minutes.

    No, each GPU is independent - if one drops out due to lack of memory the other can still continue.

    Hemm... so it's true it won't utilize the cuda on the other GPU, although one can already fit into the vram. That's kinda annoying.

    I thought, that was what I said, but...

    using a 12g titanx and a 6g 980ti... and a 10g scene... while the scene may have been on the titanx... the gpu monitor showed the 980 was working to it's limits... so it iray must still use it ... as a secondary processor of data at leat.

     I have a larger mobo with two xeons but I have a thermaltake 1350 xt gold... 
    pretty sure the more load on the power supply the hotter it runs ... the hotter the case .. the hotter the case the hotter the cards? 
    I would err on having too much power, but just like there are risers for another gpu.. there are cables that let you add a second power supply and link it to start with the main one.

    The log will tell if both cards are participating or not.

    Most PSU manufatures have one but I find Bequiet's one very simple and straight forward,

    So, I want to share my experience.
    After researching without finding any direct answer, I have a bit estimation that 650W bronze tuf gaming psu still have the room for an extra 2060.
    And... after trying it.
    It turns out, it can.

    My mobo is B450M-pro II space is a bit restricted,
    So I have to use a riser for one of the gpu.
    And my pc case can't hold both of them, so one have to be outside.
    3060 tuf gaming takes 3slot of space.

    Please do note. I don't know the effect for the long term, or the efficiency.
    But it doesnt crash for now.

    The rendering time comparison:
    3060 > 15 mins
    3060+2060 > 10 mins

    I thought it would be 2 mins :(  
    :)
