Guys im about 50% through the hardware video. It contains very detailed information on everything you will ever want to know about repairing and modding titans. When it is edited and finished I will email a copy to everyone that has already paid for our premium version of the titan miner. It will then in the very near future become a paid copy, that will no longer be free. If you have any interest in the paid premium copy of titan miner and/or the hardware video manual, now would be the time to buy. Im going to post this message a few times until the final release of the hardware video.

If you have any interest in the premium titan miner and or hardware video our order page is here:

I want to make sure everyone knows that I just released my software called "Yobit pump alert". THis is custom software that uses an algo to detect the start of a pump here on yobit, the second it starts. YOu can even filter the coins you see by price. Most pumps start less than 100 sats , so you can easily filter the cheap coins, so they are the only ones displayed Smiley https://bitcointalk.org/index.php?topic=1945937.msg20241953#msg20241953

try GenTarkins software, it won't hurt to try it

btw it kinda looks like you have some bad cubes

I had a few flaky cubes "fix" themselves by just powering down for a few hours, turn them back on and they run fine

also try factory reset on settings page, you'll lose all your settings so save your pool info

I had one cube with a bad electrolytic capacitor was looking like your bad cubes, it wasn't completely bad, one die would work, sometimes they'd all work, then another die would work, sometimes none of them would work, sometimes the cube wouldn't show at all -- after replacing the capacitor everything was fine -- that capacitor effects the power to the board -- seems hard to believe you have 4 bad caps, but it is possible I guess

btw that one bad cube I had was at times effecting the whole rig, so try running the cubes one at a time, see if it's just one cube that's bad -- if so pull it out

As I am having a full house of bad asics I am very interested in pricing policy!

It is $50 USD for the premium version of the ctstom Titan Miner with all the software mods. I am working on a detailed video that will include repairing and modding of titan cubes that will be included for free for anyone that has purchased the titan premium software. The hardware repair video will in the near future become a paid separate item. I am rewarding early supporters.  I am reworking my order page on my site. So for now if you want the firmware software with all the mods, then send $50 in LTC to LSTLJQc7hZW8KZN2b37yg6HEH978ZQTqFF then email me  the tx at titan@bitcoinlasvegas.net . I will email you a link to the latest custom titan firmware mod, and youll get added to the list to get the free repair video when its released.

It is nice to hear such pricing. What convertion price shall we use ? Smiley

I have just opened the box that did not work, took out the board with chips and looked at it with magnifying glass. I do not see any damages on the board  Shocked

If it were me I'd replace that electrolytic capacitor next to pcie connector, you can't check it while it is on the board but if it is bulging top or bottom it is a sure sign it is bad, however it can be bad with out bulging ... It's a 5 min repair job at electronics shop with proper tools .. you can try repairing it yourself but knc used some nasty no lead solder that makes it hard, takes a lot of heat to desolder

no guarantees, but that's what I'd try, it worked for me on 2 cubes

do all your other cubes work ok when that bad cube is removed?

btw if it works send me .25 btc, just kidding I'm not selling anything .. most of this info is freely available thru google and other repair info and mods are on this thread

Found in my spare stuff one capacitor for 1500 uF (Original is for 1000uF). And now starting this job ))
And one CUBE that was working do not work in any slot now. Trying, reflashing and so on.. This is the BIG QUEST. Smiley

you better use 1000uf, you can go higher temp and higher volts, but you need same uf as original      good luck  Smiley

this is what I used:

Im just curious steve, what symptoms was the board displaying when you replaced your capacitor? Ive done a couple of these and the symptoms were different both times.

the main symptom was the fan was running and the cube wouldn't be recognized properly on the card

-- one cube was completely dead and unrecognized, like it wasn't even plugged in -- I think the cap was completely shot

-- on the other cube it was just erratic, sometimes one die would work , then another, then none, sometimes it'd show everything blank in advanced settings, sometimes it'd screw up other cubes --- I think this cap was partially functioning but at the wrong values or erratically

-- the bottoms of both caps were pushed down

-- also both cubes failed after a power cable or y connector burned up

here's some desoldering porn by American Hakko

https://www.youtube.com/watch?v=sBQgbPUTIs8

this is why it'd be a 5 min job at an electronics shop

if doing it yourself you might want to practice on an old graphics card(we all have them lying around), especially if replacing the pcie connector too

Look guys Smiley
As my partner and I have graduated Robotics Faculty here in Moscow we have some vision on electronics Smiley
And as we see, this Capacitor is set in parallel to whole 12V DC input, so from here we desided that the meaning of this 1000uF Capacitor is electrical nose filter that is generating by BIG DC FAN. So if we are correct in our proposition then the volume of capacitor in this case is bigger-better!

Now we are upgrading thermal interfaces. We will put Indium on the chip and improve other thermal connections..

ok, I suppose you can always pop in a 1000uf .. let us know how you make out

not sure that your thinking is 100% correct tho, because I was testing the pcb with fan disconnected ie, no noise ??

(I got tired of putting cube back together just to test it so I did the vegas trick of just setting the heat sink loose on top and turning MHz way down to generate less heat)

We are testing the CUBE now. The temperatures are very good. But problem is that it works for 10 sec and restarts, works/restarts and so on.. So we can not test it continiously...
Previously the 1.02-1.04 firmawe worked normally, but now it is like this Sad
The 1.05 firmware does not see any cube..

google says: sometimes a higher uf is acceptable, but not always ... depends on the circuit   :|   isn't 1000uf to 1500uf a pretty big jump?

I found out that reduce the Neptune voltage by 3-4 steps and lower the frequency to 375 Mhz will make the efficiency close to 0.5w/gh, and you can use a very quiet fan while still keep the DC temp below 70c

The another, working, Cube is showing the same picture!

We are thinking now about the top cap of the chip. We have some experience of removing the CPU top plate to see the crystall under it! And we were monitoring the chip and DCDC temperatures now. So we are now thinking about that if the crystall copper cap is not soldered and is sticked with the thermal grease so it could become dry and do not remove heat effectively. Because now it is staring mining the temperatures come to 70 degree and then everything STOPs and restarts.. It looks like overheat..

it should go over 100c before it overheats

someone posted a picture of that spreader plate removed, I think it was gentarkin -- I've never taken it off so I don't know how it is fastened

Google is correct. We can make circuits for noise reduction and for another purposes. So if this is noise reduction purpose then there will be the lower limit for capacitor NOT LESS, but if it is some oscillating circuit then higher capacitor will change the frequency or amplitude.. this was our hand book Smiley http://users.physics.harvard.edu/~horowitz/aoe/
