That’s what I’m thinking. Ninja quiet fan. I ordered one
Discussion
I'm getting a consistent .75 with a slight overclock, using the stock fan & cooler on my Supra. Maybe time for a better heatsink 🤔
I ordered the heat sink that Nathan suggested in the thread. It should help
I think I'm gonna grab one too. I've got a cold room, might push for 1.0 with better cooling 🚀
Are you on a custom os or just stock?
Stock, I did enable the overclock settings though.
I wasn't aware of a custom os 👀
Just raise the temperature and the efficiency or another secret menu?
I’m not aware of a custom os either but figured you might know about it 🤣
It lets you use higher freq & voltage settings. To unlock you add "?oc" after the URL to unlock it. Tread carefully, here be dragons 🐉🔥
I was actually able to lower the voltage slightly, while raising the freq a bit.
That’s your average? With the Supra? Wow. How cool is your room?
18° in the room.
I keep the bitaxe temperature at 63°, the fan hovers between 2-3000 rpm
Amazing
I also have a fan circulating air, pointed at the bitaxe. That helps a lot too.
Good idea. I can’t lower the temperature that much in the room where I put it but I could add a fan pointed at it
💯
It helps keep the whole board cool. The asic is one source of heat, but other chips get warm the harder you push it too.
Good to note! I undervolt my Bitaxes too
Do you solo mine or point it at a pool?
Bit of both. I use OCEAN with DATUM, my own block templates coming from my start9 node. The other one is using ckpool to solo mine, but I might switch it over to DATUM too soon.
I imagine you get less hash when you under volt or does lower temperature help somehow?
I didn't notice any drop in hashrate, but if you go too low, it might cause instability or missed shares, I think. Lower voltage and the resulting lower temperature help with efficiency, so it does achieve that. The clock speed is pretty much the only thing (within properly functioning bounds) that changes the hashrate for me. I tuned my boards for efficiency by lowering the voltage and keeping the clock speed about the same.
For the lower voltage, do you think it’s one size fits all or could be different depending on the Bitaxe? Would I get the same results as you or not necessarily?
It's definitely different for each one. I'm running two Gammas, and they're identical except the solo mining one does not have the same efficiency at all, and the voltage regulation works a little differently, being always higher than what I set it at instead of lower on the one mining with OCEAN.
So the whole efficiency and hashrate curves you can get with each one is gonna be fairly unique.
I remember trying to lower the voltage once. When I checked the dashboard I was getting an alert that the voltage was low so I reverted. Do you get any of those?
Hmm, I'm pretty sure I never did. If you only lowered it a little bit, it should be able to handle that just fine. Maybe the firmware has had an update and we just are using different versions of AxeOS. You're running a Supra right? An older model?
Supra yes. That was before I upgraded the firmware though. I guess it doesn’t hurt to try again
Yeah I'd say go for it. It might just have been the interface complaining when it didn't have to. Or it might have been that undervolting was experimental and now they've worked out all the kinks. Or it might still complain haha
Do you leave it on automatic fan control? I’ll try to lower the voltage to 1150 (from 1166)
Yeah, I tried with a fixed fan setting somewhat high for a bit but then settled on automatic.
No warnings so far!
Hell yeah! :rickastley_sm:
Nice. It will vary from device to device, but here is my best with the stock cooler & power supply.
If I go lower on voltage, no hash. If I want to push the frequency higher, I'll need both a better cooling solution, plus a better power supply.
I’m at 490 1150 and 64 right now. New heat sink should arrive soon. Fan today I think
