Tuned Solo on 2 different usb hubs. My newest stick won't run without tons of errors or it will slow down after a few min when I would push it past 796.
Since last night I have added additional cooling and have adjusted the core voltage way past where the 924 needs it to be. Just luck of the asics but I would rather get the most out of them. 924/852 now seems to be as stable as I can get them. Happy with this.
I have 1 stick that will hash just happy at 924, another won't budge past 796. Can I set them to run those frequencies on the same scrypt?
Not sure what you mean by "won't budge past..."? What happens if you set both (or the 2nd only) at 924Mhz? It does not start at all. Have you increased the core voltage? The currentdraw can, when not tuned carefully, be humongeous at those clockspeeds, so the best advice is to increment one step at a time, and see what happens. E.g., both at 796, then both at 800 etc. It could be that your powersupply (in the usb hub) simply can't deliver the current needed.
Tweaking the pot meters to keep the units hashing at desired hashrate AND at the lowest power (=heat) is fun,
but not trivial.
