HashFast Sierra's Owners Thread

[h@shKraker]

Hey Mr. Teal / et. al.,

I happen to be in possession of a number of Sierra machines of recent purchase.  They arrived, I spun up their PSUs by using the power button on the PSU and nothing happened.  So ... I decided to press one of the buttons on each of the three boards in the case and viola the CoolT fans started spinning adn I felt certain there was 12VDC on the board.  It seemd to me thsi should have caused ther USB device to spin up as well.  I felt good about this part.  So, I followed the "compiling cgminer for HashFast stuff" guide at http://hashfast.com/wp-content/uploads/2014/05/Compiling-CG-Miner-to-show-multiple-die-temps.pdf and thought I was about to have me some mining success.  This was not the case.  It seems cgminer cannot see the sierra boards (each is USB connected and not chained).  I have tried to connect the Sierra to a USB3 hub and a USB2 hub and I get the same outcome ... nothing shows up in dmesg (oh yea ... I'm running Ubuntu 14.04LTS on said MiniITX / shuttle machine) *AND* thus nothing gets seen by cgminer.  I am using a MininItx form-factor PC.  The wierd part of all of this is tha my BFL SC devices adn Jalos get seen and my BE USB devices get seen.  Could it be that I'm getting borked by said MiniItx machine?  If I followed the HashFast guide set-by-step shouldn't I see  predictable outcome / the outcome HashFast described?  Any amount of your wisdom is HUGELY appreciated.

If you type lsusb, do you see the devices?
Also, you might want to try with a vanilla version of cgminer first just to ensure it's not an issue with the build of cgminer.

Mr Teal,

Many thanks for your reply.  I surely do wish these HashFast units were as bullet proof as you PepperMining units.  Back on subject now.  When I type sudo lsusb I do not see any HashFast devices even though I can hear the Sierra fans spinning like turbine engines.  Also, I've used both the HashFast cgminer git pull *AND* the latest standard cgminer git pull.  I have a standard ATX Intel-I7 machine running some Habaneros right now sooooooo .... I brought one of the Sierras to that same mining location and am gonna connect it up with the Habaneros and see if  I can eliminate the mini-itx form factor / USB hardware as the culprit.

Mr. Teal,

I plugged a Sierra into the same USB hub that my Habanero machines are plugged into and cgminer successfully saw the Habanero units but DID NOT see the Sierra.  This tells me that the ATC side of the USB interface is not the problem.  It's as if, even when the Sierra fans are spinning like a turbine and the board SHOULD have power that the Sierra just isn't there.  The odd thing is the person from whom I purchased these said they were racked up and actively mining right up to the point where they were shut down, boxed up and sent to me.  Oh yea, I do not see the Sierra boards present themselves in dmesg and I don't see them in sudo lsusb.  What gives?

I wonder .... could it be that Ubuntu 14.04LTS isn't playing nice?

H@shKraker

Possibly. I would try plugging them into another device to see if they show up there.

[h@shKraker]

AhHAAA .... looking at dmesg I noticed TONS of error messages saying the USB controller was constantly going off line, restarting, experiencing I.O errors, going offline ... lather, rinse repeat ....    Me thinks it's time to scavenge the CPU, SSD, DVD-R and build a new full ATX machine as opposed to a mini-itx.

LARRY didn't want to run for more then 2 secs... so i lowered the clocks settings down to 300 (--hfa-hash-clock 300) and LARRY decided to hash for more the 10mins. After which I kept upping the MHz by 50 every 10 mins, all the way to 604 (--hfa-hash-clock 604).

Hey,

I have 2 hfa devices that have been running in a colo for months without any problems.

Running cgminer 4.8 these days now

One system decided to throw in the towel last week with the same error, overheating.

If one starts up cgminer the first time it states:

Code:

HFS hfsb: Hit overheat temp 96.1, throttling!
HFS hfsb: Thermal overload tripped! Shutting down device

(the following times you launch cgminer it just mentions

Code:

HFS hfsb: Thermal overload tripped! Shutting down device

and no additional info. Only if you power it down for a while it cools down enough)

I only managed to keep it running if I set the freq to 125, where the temp is hovering around 98 degrees and it complains all the time

Code:

HFS hfsb: Hit overheat temp 95.3, throttling!

or similar temperatures above 95 degrees

I guess I have a cooling issue (bad heatsink, all three fans are running at --hfa-fan 100 and do pass a load of air, or a bad temperature sensor).

How does one isolate the problem to one of the three boards?

Do I have to hook up each board separately like in the BabyJet?

Or could this error be the symptom of having a bad power supply (I guess that is the next suspect on my list)?

I've had this happen in excess of 21 times on different Sierras. Its the water block. The pump is failing or the fluid has leaked out.

I have purchased a backup supply of these water coolers. They are the exact ones hashfast used. If you need one I can sell you one. Just PM me. btw, its almost always just one of the coolers, there are 3 in the sierra. I have developed a way to determine easily which one it is as its hard to tell.

Care to elaborate?

[edit]

How does one find out which of the three boards is causing the problem?

[/edit]

How much does a replacement cooling block cost? I wonder if it's even worth it at todays difficulty

It's an H80i (with a standard fan connector instead of the SATA on the H80i), but most any water cooler will work.

Hi, I am trying to help a friend who has a Seirra he bought but was never able to get working.  He bought one back in April with someone else and that guy flaked on him and he has no tech expertise and was basically stuck with it until he met me now.  I dont think a Seirra is even close to profitable now but I told him I would try to help him get it working anyways.

can anyone provide me with the latest firmware for the sierra?  I assume his has the original firmware since he has had it sitting around for almost a year.  I am able to get it working and hashing at 1.2TH/s but it constantly fails after 1 - 20 minutes with lots of USB errors.  Sometimes it will start and stop in less than a minute with USB errors and sometimes it will run for almost 20 minutes before the errors happen and cgminer crashes.   I am hoping new firmware will help.  Hashfast seems defunct or close to it, their setup.hashfast.com page doesnt work for me (i just get their website), I cant register for their site and they wont respond to support requests.

Thanks much.

At present I am running Hashfast Sierra Batch 2. on Ubuntu.

A couple of months ago I had an issue with 3 rd top the coolers . I replaced and it fixed the issue. 2 Days ago I have the similar issue with over heating . I replaced the fan , but after installing, I get the following issue.

Here is the error on console.
HFB 0 NOTICE: Hash Core Error: Still emitting hashes: die 0 core 0, count: 1300
HFB 0 NOTICE: Hash Core Error: Still emitting hashes: die 0 core 0, count: 1400
HFB 0 NOTICE: Hash Core Error: Still emitting hashes: die 0 core 0, count: 1500
HFB 0 NOTICE: Hash Core Error: Still emitting hashes: die 0 core 0, count: 1600

If I take out the third card and run the other 2 cards it Runs fine.

Any Ideas would be appreciated .

Can you post the logs.
