Best Practices For Building A Multiple GPU System

[smicha]

...

This is the way I was fighting with 580s instabilities - batter voltage settings helped a little but finally I RMAed them. The risk is greater especially when very long rendering comes to play. And it is mainly due to voltage, not heat when using watercooled GPUs. What is neat - even on stock voltage - Pascals do clock very high and custom modded bios is not that important, unless you want to break a limit for short benchmarks. But as said - for long rendering I would not exceed the limit of stock voltage (around 1.2V).

I agree that clock speed enhancements that depend on exceeding stock voltages aren't recommended, particularly for bios modes because they're a bit harder to correct. Also, I spoke with a Trention sales rep a couple of times yesterday for quotes on the parts that you need, but haven't received any prices yet. Having received no response within more than 24 hrs seems a lot strange to me for products they're marketing.

Thank you. Drop a note if you get any details.

Still no word from Trenton here - which makes me extremely uncomfortable in patronizing them. How about to you?

They emailed me and requested all business data to give me quotes. I'll report if I get anything from them.

Tutor,

here is my build log with full detailed movies - sorry for English. Hope you find it useful.

Thanks Smicha,

Those two systems scream, "Pure Genius and Masterful Execution." But, that not the biggest deal because you keep doing it over and over again, which screams, "Consistent Pure Genius and Consistent Masterful Execution." I envy all of your skills and attention to detail. Cheers for another job very well done!

Smicha, I never knew you had a channel, cool!
I would be interested to hear the sound of the rig during full blast rendering, probably super quiet.
My rig has always been very noisy...!
Also, in last few months I switched from reg stock Z's to OC Titan Z's, ran into some registry headaches, but since got it going.

Anyway... the builds are absolutely beautiful. Well done!

Hope everyone has a great 2017!

I notiused that someone is already having a good year - https://render.otoy.com/octanebench/sum ... TX+TITAN+Z . Congratulations to whomever you are. That bench performance is fantastic! I wonder what was done to achieve it.

Hello Smicha,

I especially like your Youtube video Part 24.

Which motherboard and case do you intend to use for the upcoming 20 GPU system?

Notiusweb,

What a power! Great setup. How much power does it draw?

Could you please do a test for me : watch my video and run orbx in exactly the same way I did on the video and post ms/s
