Look up Teek he is the man in Canada.  Next to Sydney Crosby that is...
WTRC.ca I believe.

[valkir]

Unfortunatly teek is way to expansive! I prefer buy from US and paid the shipping.

I already bough S1, S2 and Zeus. I always paid less from the us than from WTCR.

Anyone?

Good afternoon , someone will have idea about what may be going to the board 11 which stopped working from one moment to another and that was 4 days ago

Looks like you have old firmware, type in:  192.168.1.223:8000/Flashmega to update it.  Current version is 1.41 or 1.53

and you think that's the cause of the card 11 is stopped?

[helipotte]

Maybe.  I know I had some chips the "misbehaved" until I updated.  Can't hurt.  Check the frequency also.  One of my tubes had a blade that chips would disappear on.

Had to clock that one at 260 to get all of them working.  And keep it super cool (2 fans).

and takes a lot to make the upgrade to the boards? I did about 20 minutes ago and is still the same version

WTCR is a rip off for sure! I'm local and got burned in the past with their predatory pricing. All my gear since then has been imported.

Predatory pricing (also undercutting) is a pricing strategy where a product or service is set at a very low price, intending to drive competitors out of the market, or create barriers to entry for potential new competitors.  Yet you're saying it's cheaper to import?  Is it more expensive due to Canadian taxes then?

My uneducated guess is bad chips. Send to your seller for an RMA.

I have had the same thing happen, board just stopped working. PM'd FC & PB and was told to ship back @ +$100 for shipping back to China not really cost effective (.16BTC --> $125 + $100 for RMA == $225 for 180-220GH/s) I just added the $100 to buy a S3 from BitMainTech. The lack of RMA support in the industry leaves MUCH to be desired, Bitmain used to be the NO-Brainer, but since their sale there has been a shift.
I bought 40 boards from FC/PB of that 2 have shit-the-bed, 1 or them burned up. I presented the damage and was shipped a new board +100. #2 bed shitter did not burn-up (no visible damage), but like you just stopped showing up for work. I was told to ship back to receive new board, ugh.. -1000. AM needs a US & EURO dealer else no way they will be able to support 30PH a month sales.

I for one am NOT buying anymore chinese boards w/out FREE RMA process. FYI @ these BTC prices 5% is all that's left, so either STOP selling every GD BTC you get and HEY invest in the f'ing market you are profiting from or enjoy your noodles too.

[helipotte]

Check your cooling and power.  These tubes are VERY sensitive to this. in my opinion one fan is insufficient. Also try 260Mhz.  Can actually be faster that 270 if you have iffy

chips.

These tubes need a solid 225-250w of clean power per board to be trouble free.

Totally agree. I had 3/8 go bad. Canary was awesome enough to facilitate the exchange of 2 of them, only requiring domestic shipping on my part. The third I had to ship overseas because canary said he had no more inventory. Clearly he did or was getting some (see posts above) and just didn't want to deal with it. I don't really hold this against him since it is expensive and a pain in the ass to do all that shipping back and forth from overseas. Even with canary's generous help on the first two, I've spent well over $100 in shipping and insurance to do these exchanges and I'm still at 7/8 functionality since one board is still in the RMA process.

I get that smaller run runs of hardware probably can't be as picky about what is discarded in the QA process (if there is a QA process) but if you're going to cut corners on that end, you should offer free RMA, INCLUDING SHIPPING, on the other end.

Looks like you have old firmware, type in:  192.168.1.223:8000/Flashmega to update it.  Current version is 1.41 or 1.53

Everything is good on my setup, I'm always scared to upgrade, what exactly has been improved going from 1.41 or 1.53.

Any efficiency or notable performance improvements?

1.53 is what will show if you select the "smart" option in settings.  By default, it is set to "normal" which is F/W 1.41.

Normal=0
smart=1

Smart seems to keep the error rate lower, from what I can tell.

thanks helipotte

I upgraded from 1.41 -> 1.53 and put the setting on smart (1)... A notbale loss off GH/S @300MHz. Did around 915GH/S before and after those changes went down to only 800GH/s @ 300MHz...

Can the firmware be rolled back and how?
