1  Bitcoin / Mining software (miners) / Awesome Miners Antminer S9 firmware on: August 15, 2019, 01:01:09 AM
I saw mention of it in version notes for the past couple AM upgrades and so far have seen no mention of it here.
Anyone try it yet? ref Not sure if it requires also running AM to access it.

I only have 2 s9's left running so can't say I can give it a good test but seems the same as other 2% dev fee custom firmware here where one pays for the privilege of being able to tweak the heck out of a S9.

About the fee: This the first custom FW that clearly spells out how the 2% dev fee works.
From their above web page:
With a total hashrate of 15TH/s, no more than 0.3TH/s will be used for the mining fee.

The mining fee consist of two pools named DevFee that are running mining in parallel with a slow speed mining. Please note that because of the slow speed these two pools are working with a very low difficulty level, resulting in that they will produce quite high number of accepted shares. A high number of shares doesn't indicate that the DevFee pools are taking all hashrate - it's a result of the low difficulty level for each of the shares.

Again, curious if anyone has had a chance to kick the tires on this FW. Does it use the known security risk xnonce for the parallel mining?

edit: added emphasis to the dev pool hashrate
2  Bitcoin / Mining speculation / 2.5nm transistors produced: Thoughts on them & miners? on: December 10, 2018, 06:32:47 PM
Well researchers have produced transistors as small as 2.5nm using techniques that look compatible with current bleeding-edge 7nm processes. Smallest 3d transistors yet

Now given the current downturn in the market I do not see these showing up in miners anytime soon, hell, 7nm miners are just out and sales are - meh, but still... Thoughts?
3  Bitcoin / Mining support / s9 > batch 16 and Auto-Tune Issues on: October 13, 2016, 11:08:18 PM
Just got a s9 batch-17 and... Bitmain has changed the firmware.
I will post in detail tomorrow but for a summary of changes:
  • They have changed the board channels used and so the temp reporting channels. Now using channels 6, 7, and 8.
  • Looks like changing the frequency may be gone. There is no longer a GUI option to change it. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well per-board. When all is done, the boards report different frequencies. This could turn out to be rather -- interesting.
  • Looking at the Kernel Log it shows several lists of freq and voltage it tries for each board. A note at the beginning of each list says that freq is now stored in the PIC. Now does that mean that a warm boot bypasses the testing -- dunna know but hope so.

I'll post the Kernel Log tomorrow. Also fan speed no longer has a setting on the BMminer GUI. Log says is set as needed starting at 40% Oh, the fans are on different channels as well. Think fans are now reported in position 6 an 8. I'll verify tomorrow. edit: Fans in positions 3 and 6

Due to the time it takes for the new booting process -- around 4 min or more -- better set dead miner/offline/etc monitoring to wait at least that 4 maybe even 5 min before trying to issue another reboot call to the miner...

Frankly, during the setup process for miner name and pool assignments the reboots needed were taking so long that I thought the miner was going to be a DOA!  Shocked Folks, keep in mind that much longer time needed to come to life before you start to get miffed/worried like I was. A couple times when it was taking A LOT longer than was normal with the earlier batches I forced reboots trying to get the miner to respond. thankfully it didn't brick.
4  Bitcoin / Hardware / 43THs RT s9??? WTF... on: September 12, 2016, 11:11:15 PM
This started about 15 min ago, around 6:55p Eastern
Note card-3 (chain 4)

After a soft boot STILL card 3!

WHAT in the HELL???
5  Bitcoin / Hardware / Modding VR control on the s9? on: July 27, 2016, 01:22:02 AM
Has anyone paid attention to the power input area of the s9 hash boards? This detail I took from the pic of of the s9  board posted in the ad for it shows:

In the lower-left, doesn't that look suspiciously like a programming port for a voltage controller? The switching FET's are there under the heatsink (nice touch!) as well as a honking big inductor so I have to assume that the s9 does use a buck regulator.

Hmm. Curious minds have to wonder what might be done with that...
