frames? ... i build them custom ...

the frame ( 1.5mm square aluminium tubing ) - edge connectors - screws and lugs - angle iron ( 90 degree edging ) ... all this comes to approx $70.00aud ...

but initially i had to buy the cutting and measuring equipment as well as the files and mallets ( yes plastic head mallets - not hammers ) ...

parts alone - not counting labour - if you are looking at adding teh countless hours to design the thing in the first place ...

prototype 1 - prototype 2 and now prototype 3 is probably the design we are going with ...

hope that helps bathrobehero ...

I must say that I didn't have any problem benchmarking amd cards: if the room was hot, I'd put the fans at high speed, run the miner and wait a couple minute to stabilize, and that's it. I could make 100 changes to a kernel in a day and check them all, accurately.

On nvidia I have throttling problems I can't easily fix (the cards reduce clock speed in a number of situations I just can't predict), overclocking/downclocking is more difficult as the cards tend to change clocks by themselves, and the hashrates fluctuates wildly, and even changes between ccminer runs.
The rig is headless so I only have nvidia-smi to work with, and it can't set the fan speed.
So when I make a little kernel speedup, I spend more time benchmarking it (to be sure it's indeed an improvement), than making the improvement itself :-/
Maybe there are some nvidia-smi settings to make it more stable?
Or maybe on windows it's different...
Finally I may need a workstation with a nvidia as main card, and work on it.
