How much extra for shipping to US? To Canada?

If you require local pickup only, you should at least give an approximate location...
303  Bitcoin / Mining support / Re: Fixed frequency T9+ firmware? on: September 02, 2018, 03:05:24 AM
Thank you for that link, it was helpful. I also realized that bmminer-mix supports the T9+, but in the code it is referred to as the S9+.
304  Bitcoin / Mining support / Re: S9 - Fan Error when 2+ boards hooked up on: September 02, 2018, 03:03:41 AM
No, only 1 fan is working. The one reading 720 is only spinning because of the other fan forcing air through it. Usually it is the exhaust fan that dies.

You are right, but it is not always the exhaust fan that dies. In my high corrosion area the intake fan fails maybe 4 out of 5 times.

The higher numbered fan sockets are closer to the edge of the controller board. Just follow the wire from the socket to find out which fan you need to replace. (So in your case, fan[3] is lower and its socket is farther from the edge of the board).

You can use bmminer-mix to recompile bmminer.sh as you like. I wouldn't go much below 8.4V.

The definitions you need to edit are around line 588 of https://github.com/bitmaintech/bmminer-mix/blob/master/driver-btm-c5.c

I think it is not good to use some custom firmware because you don't have a chance to recover or reflash it back to its original firmware.

If you do what I've just described all you have to do is replace bmminer.sh, you can make a backup of the old one and restore whenever you like. Or, you can always go the upgrade section and flash it new again.
306  Bitcoin / Mining support / Re: Error of set PIC FLASH ...? on: September 02, 2018, 02:56:31 AM
I see this issue almost daily. Usually rolling back the firmware will let you run while ignoring the issue.

If a board is zero you can replace the PIC with one from a spare board if you want to. Bitmain doesn't seem to sell spare PICs.

I have also seen the issue happen because of a faulty ribbon cable. Try replacing the ribbon cable to the board giving you the issue.

If you get the 413 error when flashing firmware, use a microSD to flash manually.
307  Bitcoin / Mining support / Re: HELP - Antminer S9 - Shows no speed after running for 3 minutes ??? on: September 02, 2018, 02:52:46 AM
Try running one hashboard at a time and see if the issue still occurs with each one. Could also be a power issue, have you tried another psu?
308  Bitcoin / Mining support / Re: Error of set PIC FLASH ...? on: August 30, 2018, 06:26:44 PM
Probably something wrong with the hashboard.

You can always try using the package to fix fw upgrade, flash it to SD card, move the jumper pin and flash using microSD. (Flashing the april firmware of course).
309  Economy / Computer hardware / Re: [WTS] ANTMINERS, S9, A3, D3 on: August 29, 2018, 09:16:32 PM
What is the approximate shipping charge to USA? And to Canada?
310  Economy / Computer hardware / Re: Selling lots of Bitmain L3+; D3; & APW3++ [Bulk Discuounts, Vetted Seller] on: August 29, 2018, 09:15:27 PM
I bought an L3+ and some APW3++ from him. They arrived quickly and worked great!
311  Economy / Computer hardware / Re: [WTB] GTX 1060 3GB single fan on: August 28, 2018, 02:33:57 PM
Accepting forum escrow?

$85 shipped is low for a 1060, even the 3gb model. You might only be able to find crappy used cards at that price.
312  Economy / Invites & Accounts / Re: <WTB> Dream Market account on: August 28, 2018, 12:21:26 PM
I have a dream market account, about a year old. What is the price range that you are looking for?
313  Bitcoin / Project Development / Re: Need help in user research (new mining software) [Cryptocurrency Mining Survey] on: August 27, 2018, 03:04:26 AM
On question #8 you seem to have cgminer listed twice.

Also, might want to add ckpool to your list of pools.
314  Economy / Computer hardware / Re: [WTS] BITCOIN Mining Set Avalon 821 on: August 27, 2018, 02:51:45 AM
How much are you charging for shipping to US? To Canada?
315  Economy / Computer hardware / Re: For sale ASIC miners SHA256/Scrypt/Miners on: August 27, 2018, 02:50:34 AM
You know bitmain is selling S9i 14.5th for only $414 and with PSU for $499? With coupons they are even cheaper.
316  Economy / Computer hardware / Re: WTB - Bulk S9 with PSU on East Coast on: August 27, 2018, 02:48:20 AM
Used machines acceptable? What about older models advertising only 11-12 TH? PSU can be any model or only bitmain?
317  Bitcoin / Mining support / Re: How To Overclock Your S9/T9+,T9,R4 Free. on: August 25, 2018, 01:11:46 PM
can this be modified so you can pick the frequency that works best on your particular miner or using a lower watt PSU? for exa,ple instead of 17TH at 2,300 watts can this be clocked lower to run say 15TH at a lower power draw so it can run on an 1,800 Watt PSU?

In bmminer-mix you have to define BMMINER_VERSION to a fixed frequency option and upload the new bmminer.sh. After that, you can use minerAdvanced.cgi to set the frequency to anything you like.
318  Bitcoin / Mining support / Fixed frequency T9+ firmware? on: August 24, 2018, 10:33:27 PM
Are there any official / commonly used T9+ fixed frequency firmwares, or must we compile our own?

I'm interested.
320  Economy / Computer hardware / Re: [WTB] S9 w/psu on: August 24, 2018, 02:27:45 AM
Looking for brand new only, or is used equipment acceptable?
