@GreaterGoodMining do you know how the chip order goes? My temps on 6,7, and 8 are higher than all the others and would like to figure out why but I don’t know which ones they are in the board
Love that you were able to use the graphs to show the correlation between ambient and hashrate. This is exactly the kind of thing I was hoping all the graphs w/ the synced tooltips would help people troubleshoot. And it's not just you, these things absolutely suffer in performance when the hash chips start hitting low 40s and below. 50s does indeed seem to be ideal for KS0 Pros. Also, your hashrate on the unmodified one indicates you're voltage starved. 280 Gh/s should only require ~220mhz offset (550mhz * 80ghs / 200ghs = 220mhz). Assuming you don't want to increase voltage any further, you should try reducing your clock offset to 220, or maybe find some middle ground between +220mhz and your current +275mhz offset that might actually give you a higher hashrate.
Thanks I appreciate the info! I did feel like I should've been able to get a bit more out of the mostly Stock KS0 Pro. I'll try decreasing the clocks a bit and see how it does. I was starting to worry about the power stage temps and it did seem like things improved when I backed off the clocks a bit. Thanks again!
I should have kept better track of the power consumption throughout the whole process while I was shooting the video. But it became very tedious because I was making so many adjustments over a long period of time. I decided just to include the power consumption that I ended up with. I will try to make sure I take the time to include power consumption more frequently in future videos! :]
@LostJediJC offset first until machine starts to act funny or the increase stops being effective. Then tweak up voltage a tiny bit and see how machine reacts. Then go back to tweaking up offset again
What temperature can the chips withstand without being destroyed? What clock offset/voltage offset are you satisfied with? I don't have to have 300gh/h but a bit more like original would be better. Better to take it easy on the device, that was expensive :-)
If you follow my other video where I show how to prep the KS0 Pro then you should be fine with overclocking. Every KS0 Pro is different and ambient temperatures matter. I recommend reading the read me file provided with the overclocks to learn how to do this properly for your own setup. My settings might not work well for your KS0 Pro

Is it okay to just take the two side panels off to have it breath better or should they stay on? I’m just running a dual usb fan below the base blowing up. No oc’s on.
Yep you can take the side panels off no problem. I do that too just to keep temps down a bit. If you're worried about anything getting into the miner you could buy side grates from Meter Box
Hi man! First of all, thank you very much for the videos of ks0 pro oc, they really helped me! One question, In the video where you make the modifications (heat sinks and everything) you say that you were blowing air from the power conector to the ethernet conector (like everybody does), and that you were going to try changing direction to improve heat sinks performance and avoid the things in the middle. Have you tested this already? How did it go? Thanks in advance. Keep going with this nice videos please, they help new miners a lot :)
Hey thanks for watching! I havnt done extensive testing blowing in one way Vs. The other yet. Blowing in from the ethernet side makes sense to cool the power stages with the copper heat sinks better but then it's harder to access the IP report button but that's not a big issue because static IP etc. Blowing in from the power side makes sense in a different way because the barrel plug gets HOT and I worry that it could cause an issue. I might try a push pull set up again because the fan on top of the heat sink might not be necessary since it mostly helps cool the chips and dissipate heat from the inside. The chips are cool enough, and actually sometimes too cool when the temps drop at night
would adding heatsinks to the metal plates on the chip side of the board not bring the board temp down without bringing the chip temp down lukewarmminer said some people that had problems getting them to run 340, found it helpfull adding heatsinks on the metalplates that also are there to get rid of heat to me it looks like those plates are there to cool the board, but maby im wrong
If you want to keep your chip temps up and board temps down, get a more powerful fan and use the push pull method with two shrouds and remove the top fan off the heat sink.
Would media blasting the powder coating off help with cooling? I don't have any miners (just ordered 2 kso ultras), im guessing the hole thing is aluminium? I would think bare aluminium would be best for heat transfer
That's not really necessary. The bottle neck is the power stages getting too hot. The heat sink works fine for dissipating heat especially if you use a higher quality thermal paste and pad. The chip temps aren't as much of an issue especially if you use a shroud kit

Question - you mention stability. Is that refering to only the power stage / chip temp - or does it include the hash rates? 2 Hr hash rate is 338 - but 5 min has a swing of 30 GH/s (1 hour range - low 323 / high 360). 30 min avg - 340. KS0 Pro - added heatsinks, new pads, MX-6 paste and upgraded PSU. Fruition shrouds with AC infinity blowing into the ethernet side - est 30% fan. 400Mhz / 46mV. Power stage avg 87 - no spike over 93. Chip temp avg solid @ 48 / max 51.Chip voltage avg also solid @ 438 / 443 max .
Sounds like you're getting great results! The 5 minute and 30 minute will fluctuate like that, it is normal. Instability means the rig will crash or your hahsrate will drop drastically and stay there.
Hi thanks I appreciate it! Yes I've got a regular KS0 at around 180 to 185 gigahash. Didn't modify it, just put a Axial 1238 on top and aimed it down to the heatsink. I should've tried to do a video on that one too.
oh it is DEFINITELY silicon lottery. I have one pro running 300ghs with clocks of 275 offset / 24 mhz voltage. The board temp on this one is only 100. 2 other pros with the same upgrades/repaste/repad/copper heatsinks, the boards running near 125c. I have 3 new special edition pros that i have heat treated and i need to overclock. will use pbfarmer here as well and test. wish me luck
100% my first KS0 pro with full mods hurt my feelings and wouldn't OC past like 290ish no matter what tried. This batch of Green Machines for me has taken much more abuse so far. I hope you hit the jackpot in the silicon lottery this time around brotha!
My OC: 300/32, 170w, power stage 91C, Chips 51C. Blowing to ethernet and sucking from power side. Stable ~315gh/s. New paste, low aliuminium heat sinks.
I wouldn't bother ordering the stock PSU from Iceriver. You'd be better off getting a better one off Amazon like the one in the description of the video. If all you have available is the stock PSU I would highly recommend using a Meter Box to monitor the wattage. The closer you get to the max wattage listed on a power supply, the less efficient it gets
@@RandomMiner I used a 230 watt laptop power supply. I put the link to the exact one use in the description :] I haven't tried The Veteran Miners cables with a HP server power supply yet but I probably will do that in a future FAFO session!
@@RandomMiner I don't think you want to do this if you're planning on OC. ATX PSUs run 12v instead of the 19.5v you're getting on the laptop PSU, meaning 63% more amps running through the barrel connector. They tend to melt or worse as they're not rated for that draw. Many people running 12v are soldering the leads directly to the boards.
Now that you've seen where the bottlenecks are on these machines, what do you plan to do about it??
