Bringing the trials and tribulations of my urban crypto mining journey to the masses. Might have missed documenting Chapter 1 (Home Mining) and Chapter 2 (Office Space Rental), but Chapter 3 (Industrial Facility) will hopefully make up for it.
Payed the extra got one from ebay and within 2 hrs of startup it's not working. Applied the update and changed mining pool and it's now not working. Got any good connections for trouble shooting?
Sorry to hear your troubles. Was the unit still sealed? Best bet would be to reach out directly to either who sold you the item or Canaan support: www.canaan.io/supports/
@motorcityminer it was sealed but I went about the red panda way and put heat sinks on it to keep it cool. Voided the warranty. But I reached out to the site I bought it from waiting to hear a response
@motorcityminer i tried looking at the board didn't visually see anything. Doesn't have that smell either. Seemed to be working until I updated it. Hopefully it's something from the update. Would have made for a good video.
depends on when you get them, the future outlook of coin price, etc. lots in play. original KS0s did very very well. new ones not so much. hard to say what the future holds.
@@motorcitymineryea i mined 150k just gpu and a tiny bit of e100 … didnt pull the trigger on rx0’s … went all in to my extent on al0 and al2 lite (still waiting on that of course) … might grab one rx0 eventually… but yea missed that first batch boat so not super eager … might swap a little btc for rxd
nice, yeah most my RXD bag is from GPUs and FPGAs. I am too far in the hole on ALPH asics so called that a loss and passed on the AL2 Lite as it would never turn around my fortunes. Hopefully you have better luck on the ALPH front.
Love to se you trie to fix it yourself and succeeding, if those lovely welds fail again you can always count on cable ties!! or you could clean all the solder surfaces with isopropyl alcohol, pre heating the ''nuts'' and wile you place them on the board continuing heating for a wile ''5min'' with the soldering iron. If you clean really well the soldering iron tip you can place the tip into the nut treads to heat it up then place it to the board and hold it there with the iron, put the solder right on the 90° between the nut and the board, should wick right into the board and nut... Ooh, your are gonna need some needle nose pliers or tweezers. Hope it helps.
Interesting idea using the nuts to melt the solder. Would probably result in a cleaner joint too. Will have to try that next time. Might need a hotter gun though.
If it works, that is all that matters!! that is a pretty lackluster design though. they should have made it so the heatsink mounts slide in from the back side of the board, wouldn't need to depend on solder to hold them in place then.
@CMC dude thanks for the fan direction idea .. I got custom 6pin PCIe to 8pin EPS cables from TVM so I do not need to put the fans on the outside, I am getting all low 60’s high 50’s ..
@@motorcityminer yeah TVM rocks .. but yeah try to work out a deal from him, i know it cost more than buying both adapters if you don’t already have the cables, however just having a clean direct from the PSU PCB directly to the GPU with no adapters, and the ability to fit cleanly without putting the fans on the outside is a plus too.. buy yeah you already got everything working perfectly so if you really going to do it you can do it slowly.
yeah, will definitely be over time. but want the 16G wire TVM uses so I can really push these cards on Kawpow as well. For pretty much all other algos, the 18G wires I got are fine but these cards are Kawpow beasts.
@motorcityminer Thank you. This info helped me a lot, Im doing this step by step. Just a question can you let me know where can I buy those dual 8 pin PCI-E, because those small X12 only come with single 8 pin ends. Thanks
I would hit up the @TheVeteranMiner (theveteranminer.com). He uses 16 awg cables which are optimal for high powered cards like these, especially if you are thinking of running kawpow @ 200w+ on these.
i just completed payment for one of these cards on ebay from a diffrent seller then the respecstore where alot of ppl bought them im just hoping mine has the better vbios it says its flashed to the 16gb mining bios tho it didnt come with the power adapter cord tho so ill have to find a esp to 2 male pcie cord
yep, I have both vBIOS versions. V100 and CMP. Both are capable of about the same performance but CMPs require considerably more and different overclocking. V100s are a little more plug and play to get max performance.
If you havent changed the thermal paste, do it! Every one that I got had the paste absolutely baked! I installed mx-6 thermal paste and much better now. I use (2) 40mmx40mm fans 13000rpm for each card in an open frame rig.
Yeah these cards are pretty old and were run hard so not to surprised on the paste situation. Will def have to replace for higher wattage algos. And nice mod to add active cooling so it works in open air rig!
Thank you for this. We’ve had a few 90° days here lately, and card temps were spiking. I have the same cards and case, and I had just seen someone mentioned that Ovalbore had recommended reversing the fans, and now I see your video. I went out to my garage and made the change in fan direction and taped off the stray openings, and the result is a very noticeable dip in temperatures.
The extra cables are for an atx psu with thinner cables, to relieve the current strain on the psu by halving the current on each cable. I have used psus where the cables got warm to the touch, not good.
That makes sense, that way less load on each pcie cable if 18awg or higher. Guess they messed up verbiage on the instructions since they only talk non vs. modular supply.
you should be able to change the memory on either BIOS for these cards. you may have to do within the command line of the miner rather than within HiveOS overclocking though.
right now, XelisV2 ~ 34.6 KH @ 95-115w using --lock-cclock 985 --mclock 150 --pl 120. as @ruskyscryptocave said though, power will fluctuate consistently, but most my cards are averaging 108w
I used 3x140 fans in the back to suck air out (push/pull) similar temps to yours now, will try your method to see if cooling is matched so I cam save some power.
@@motorcityminer Your method is better. Both core temps is between 3 and 8 degrees lower, depending on a gpu. Your method also requires only 4 fans whereas I had 7. Also, for my 2nd rig, I put in two 140mm fans (with 120 to 140 adapter) - only 3 fit, so I decided to do 2 140mm in the middle and 2 120mm on the outer edges, this seems to improve both core/mem marginally by 2 to 3 degrees. The coolest 100-210 between two rigs on xelis is 51c/58m (140mm rig), the worst is 52c/64m (120mm rig). Cheers!
Nice! How did you manage to power 12 of them, there are not enough power output plugs? I used 3 per 2 cards to get in 10 max, just to make sure my cables dont burn out if the gpu goes tdp. Did you use 1:3 splitter for the mobo?
I replaced the PCIE cables with 16awg and used PCIE splitters 1 one of the pcsb octo x12's. Just got 12 more and going to explore options. Not sure I would mine kapow on these
this arrived just in time! Many thanks Just got 12 more delivered today which will be packed into a mini x12. For the PCIE did you use a custom cable to connect both connectors? Or a splitter
Nice! I have 16 gauge dual 6+2 pin cables for each card atm. The only algo I have found that really would warrant even better cables is running kawpow max out on these. Hoping to get into more algo specific content on these in the future.
@@motorcityminer confirmed reverse fans cool these far better. Went from needing 80-90% fans down to 65% and cards are running about 5-10 C lower. Thank you
@motorcityminer I have a mini 12 from PCSP on the way, I believe it only has one 6+2 cable per card. Would I need to replace the wiring to accommodate for two 6+2 per card?
Good to know. I'll have to do this come spring time or if I tear the rigs apart any sooner. Looking forward to unleashing them on some kapow coins in a month or two when the temps drop a little more
Nice, and yeah, these things are Kawpow monsters. The reverse airflow definitely helps get more headroom on high wattage algos like kawpow. Can easily get 62+ MH @ around 250w
Same, but I have also found w/ the proper tuning, the CMP vBIOS versions can hit the same performance on most algos. There are a few exceptions where I wasn't able to achieve the same efficiency but so far I have been able to hit the same max hashrates on both vBIOS for every algo. More content to come.
For me I’m done with mining Kas unless you have a big machine that can mine fast or you can get the miner fast it isn’t worth the cost of buying by the time the machine arrives it’s hardly profitable
Yeah, the little machines are all kinda bricks at this point. Unless you get great deal on the first batch of big machine. Really becoming a coin just for the big farms.
My KS0 ultra never worked, never mined. First factory repair fixed nothing.. it's currently on its way back to Hong Kong for a second repair. Utter Junk
MY KS0 Ultra was JUNK out of the Box too. Turned on but would NOT mine.. It's on its SECOND trip back to the Factory Repair shop. $104 shipping each trip.. First repair did not fix cra p.. . Iceriver is Garbage.
Yeah, really hoping for a shipment delay on Bitmain's part. IceRiver batches tend to be rather small so shouldn't affect earnings to much, especially since they don't have a full size ASIC yet.
Do you know how to unlock all the CPU cores on this board? It seems like they configured the BIOS of this board to use only 2 cores so it doesn't overheat.

My KS0 Ultra has been JUNK OUT OF THE BOX. Never hashed never worked here.. Went back for repair once, never worked here, after return. They claim it did at the repair shop but never explained what was wrong the first time. It cost $110 to ship it back to Hong Kong, now it could cost another $110 for shipping a second time... Customer service is slow, seems like they are dragging their feet to run out the Warranty period. Iceriver is Garbage.
Sorry to hear about your ordeal. I haven't had any issues w/ any of my 15 IceRiver ASICs. Even the broken unit I purchased secondhand, they were easy to work with to get the replacements parts I needed. Hopefully they get back to you asap.
