imho it is Innsilicon out of china...making a push at scrypt data halls *just a guess I've no real clue* (that or knc has made an 'evil' titan data hall or two..and is not saying...hey I really, really hate those guys ...everyone is entitled to "one' zonky conspiracy theory ..don't ha know ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:)

Well I 'fondled' my Titan fpga chip as you asked in the above post. (I feel dirty) It is cool to the touch...no real heat at all on this chip. This is true of BOTH my Titans. So I guess 'neutral heat" is what I'd say neither hot nor cold and barely warm at that ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Thanks! Hm. This one is running at 50c, which is actually quite warm. Maybe ones that blow up run hot, I'll have to wait till I get another one.
In the meantime I now know what blows up Neptunes and probably titans (Note: NEVER move a hot or running unit, let them cool first) and can fix blown Neptune boards that don't talk back to the controller. It's a bit of a bitch to do, but for a blown Titan it's probably well worth it.
Now back to working on the water cooled Neptune. Having conformal coating on my water blocks (used to mount them on backs of boards) is cutting the efficiency. Likewise the chips run hotter than the temp sensors say, watch out....

just to make sure the FPGA chip is the 'frigging' big chip on the Titan board right? (likely but not like they are labeled) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi.ebayimg.com%2Fimages%2Fg%2FyWcAAOSwv-NWViu1%2Fs-l300.jpg&t=665&c=bRRuytp6qKfhMA) (the large chip ..square...on the right side of the pic above.....I assume that it is not a 'hidden' chip under the pi controller and daughter board....) er make sure the 'water cooled' neptune project also works with Titans...you'd get more action out of the expense of making a Titan water cooled then a Neptune at this point in time..just saying ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

(the large chip ..square...on the right side of the pic above.....I assume that it is not a 'hidden' chip under the pi controller and daughter board....)
Yes, that is it. It's actually a pretty busy little bee all things considered. er make sure the 'water cooled' neptune project also works with Titans...you'd get more action out of the expense of making a Titan water cooled then a Neptune at this point in time..just saying ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) They are very similar boards, so what works on one should work on the other. Just sanded down and re-mounted the water cooler block, it's holding a nice 44c, which is actually 56c as read from the bottom of the board. Top temp on the bottom of the board is 68c under some of the DC-DC supplies, they do dump a lot of heat into the board planes.....

Lightfoot, any thoughts on applying a conformal coating to the titan PCB? I run mine in unconditioned space and I am near salt water, do you think it is a good idea to apply in this situation? risk vs reward, some loss of heat transfer vs protecting circuit from the environment -- I won't be applying it to any heatsinks, just the pcb -- I know from soldering this board that it is pretty tough, maybe conformal isn't necessary, ie a lot of work for minimal reward -- what do you think? txSteve

Hrm. Conformal coating does keep out the crud but does keep in the heat; I can see a 20c difference between having a thin layer of conformal coating on the water block to Neptune chip interface, sanding it off really dropped the temps.
Honestly though I don't think environment is that massive a deal with these kinds of units. Unless you're really running it in a dirt farm, or got the thing submerged in crummy water it shouldn't be that terrible. I had some thoughts on pictures of another company's miner that was refused RMA due to "environment damage" and thought "that's not unusual". Besides if it's a really corrosive atmosphere the fan will probably seize first, which will overtemp the device.*
A properly conformal coated board though can take a lot of environmental damage: I once fixed an electric car controller that had a leak from the water plate inside the controller box. Literally covered everything with oily, antifreeze laden gunk. Cleaned the boards, cleared out the fault maker (the pre-charge relay) and the board fired right up with no problems.
However in that case you have 400 volt DC lines on the board, and that kind of voltage will bridge gaps caused by gunk. 12 volts? Not so much.... .6 volts? Really not so much.
What do I use for home electronic repairs? TechSpral Fine-L-Kote SR silicon conformal coating spray. Light coat is all you really need.
Hope this helps.
* Then again I saw discussions about another that had been rne in in a closed room in a 110+ degree day in the Australian outback and they were complaining that it was throttling. No AC no nothing. Um.... that's what is called "way outside parameters". Too many manufacturers build for a 68 degree data center, which is not what the typical home has (there is a big difference between how much heat a radiator can dissipate between 70f and 80f)

yeah it helps the hottest it got here last year was 105f and tarkins mod throttled it down for a few hours The fan guards are rusting, which is what got me looking for a solution and I found the conformal coatings. To be honest the boards look fine, just dirty. I guess I'll take them apart, clean em with alcohol, blow them out, and take it from there I already bought the stuff, maybe I'll do one cube -- see if any adverse effects. here's what I got http://www.amazon.com/gp/product/B008O9YGQI?psc=1&redirect=true&ref_=oh_aui_search_detailpageand http://www.amazon.com/gp/product/B005DNQX3C?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s01thx

Hey BE CAREFUL OUT THERE. I'm calling a scam alert until I hear otherwise from GenTarkin himself. I assume if he had put up this website and it was legit, he would have told us about it. http://gentarkincustomtitan.pcriot.com/?It looks like someone over on LiteCoinTalk paid money to this site and hasn't gotten anything in return, so unless GenTarkin tells us it's legit... scam alert. Spread the word.

Also, if you go to pcriot.com, you get an "account suspended" page: http://pcriot.com/cgi-sys/suspendedpage.cgiWell, hopefully the website is legit, and maybe Tarkin is just on vacation.

I talk with Gentarkin on a daily basis , many times multiple times a day. He has made no mention of this website. So Im near 100% positive this is not his. He is away for the holidays , and I have no way to reach him. A red flag is our additional licenses are $30 NOT $25. Im not sure what we can do, but I have some ideas. Also the fact that someone paid and got nothing. That right there tells me its not Gentarkin. I can tell you with 100% certainty he would NEVER do that. Youll never meet a more honest person.

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 https://bitcointalk.org/index.php?topic=1945937.msg20241953#msg20241953

Just wondering why does the v.99e restarts the Titan or BFGMiner every 4-5 hours. I have set the max temp at 90 and all of my dies are staying below 70 now that its cooler here. None of the dies are bad, Current (A) is between 37-40 @ 300 MHz.

The intial and primary goal of my firmware since its inception and to this day has been to bring "sleeping, dropped or w/e u wanna call them" dies back to a hashing state. In order to do this my firmware issues cube power up / downs to bring back the affected die(s). In order to carry out a full power cycle on a cube bfgminer has to be stopped prior to the power up / down then started again after the power cycling. As to why the pi may be rebooting on your. The pi reboots whenever it detects communication via the i2c bus to the controller board stops working(most likely due to the controller board locking up). Rebooting the pi instructs the controller board to power cycle & reflash the binary code to the FPGA which reinitializes the FPGA on controller board. The controller board hanging like this, Ive witnessed over time are completely random. It can happen more often when voltages & clocks are being changed. (in some cases it will happen much more often during tuning of dies when my "energy saver" edition gets released) Its most likely caused by shitty code running on the FPGA, which unfortunately is completely closed source.
