checked today power drain with watt-meter, my results:

S9(13.5T) - freq 625 (13.5 TH) - 1495W
S9(13.5T) - freq 700 (15.0 TH) - 1570W

is it safe to run freq 700 for a long time with Bitmain APW3++ 1600W ? with 1570W drain it is ~ 98% of max limit

Yeah it's fine I have had an s8 run at 1675 on bitmain apw3++ surprsingly you can quiet a bit over 1600w on some before it goes into protect.

Go to minersip./cgi-bin/minerAdvanced.cgi and change the frequency of the miner. I would start at around 675mhz and run it for a few minutes and check for hardware errors.

minersip is the IP address of your miner

I'm sorry. I must have misread the url. It works now. Thanks very much for the help.

Out of curiosity, is there anything like this mod for the L3+? I found one by a dude named Blissz, but his links were down and the forum has been dormant since January.

Thanks again.

I have seen similar before and in some cases adjusting/tightening the connectors for the fans, and cards helped to resolved the problem.

unlikely, if it would be some physical connectors issue, it would show same issue with stock firmware.

taserz, do you have the same bmminer binary for S9 13.0T models?

well, i tried that bmminer880 on ~20 S9 13.5T and 14T models, so 15 are good, but 5 rest(only 13.5T) show Chip temp above 100C with even 650 freq in 1-2min after start. i dont understand what is the difference between that antminers, all have identical spec: S9_V2.54 HW: 16.8.1.3 Bmver: 2.0.0 Firmware: Fri Nov 17 17:37:49 CST 2017

any thoughts?

800 is around the limit you can go on the S9 with 880. I mean you can go higher but the HW error rate will quickly climb to far and outweigh it. The errors rate looks good at about 1 error rate a minute after running it for some time it should steady out or drop too. If you ran 890 I bet the 800mhz would have close to no HW errors but would probably trip the 1600w psu and shut it down. Keep it at 880 for 1600w psu

Hi

Thank you for this.

I have installed the bmminer880 mod, using the auto-freq default firmware.
I don't have in my house a bitmain 1600 psu. I have EVGA G2 Gold-1600 watts.

I am running one of my S9 13.5 at 700 , and its giving around 14.9 Th/s. Good stable for about 30 mins. Good temps below 86 for chip2.

At 725 it gave me a little bit more : ideal-15.6, avg: 15.3 Th/s- good stable for about 15 mins. Good temps below 87 for chip2.

At 750 it gave me a little bit more : ideal 16.159, avg: 15.7 Th/s - good stable for about 15-20 mins. Good temps below 90 for chip2.

Few hardware errors in two of the cards
chain 6: 1 Hw-error
chain 7: 7 Hw-errors
chain 8: 0 Hw-errors

At 800 it gave me a little bit more : ideal 17.236, avg: 16.4 Th/s - good stable for about 15-30 mins. Good temps below 94 for chip2.

This one game me more hardware errors

chain 6: 40 Hw-errors
chain 7: 45 Hw-errors
chain 8: 3 Hw-error

It also seems the discarded increases a lot when running at 800, and the pool does not reach expected high values for hash rate. Maybe an observation issue... but just reporting.

I am afraid of increasing the Freq above 800. I will repeat the above tomorrow to try to measure the power draw at the wall. Will report if I can make it.

In any case This is AWESOME! Thanks!

Thanks for pointing this out for the user above you as the is the only step they did not do. They were running it at 8.8v correctly.

Hello Taserz,

First, I'd like to say thanks for all the work you've done.

Second, I was hoping you could help. I have a 13.5 S9 that I'm trying to overclock with your mods. I have followed the instructions on page one. I flashed the fixed frequency firmware (650) from Bitmain's website and I have replaced the stock bmminer with yours (880). After the mod, in the kernal log, I can see two different frequencies:

Code:

Miner Type = S9
set_reset_allhashboard = 0x0000ffff
set_reset_allhashboard = 0x00000000
set_reset_allhashboard = 0x0000ffff
set_reset_allhashboard = 0x0000ffff
Check chain[5] PIC fw version=0x03
Check chain[6] PIC fw version=0x03
Check chain[7] PIC fw version=0x03
Fix freq=650 Chain[5] voltage_pic=108 value=880
Fix freq=650 Chain[6] voltage_pic=108 value=880
Fix freq=650 Chain[7] voltage_pic=108 value=880
set_reset_allhashboard = 0x0000ffff
set_reset_allhashboard = 0x00000000
Chain[J6] has 63 asic
Chain[J7] has 63 asic
Chain[J8] has 63 asic
Chain[J6] has no freq in PIC, set default freq=650M Ooooooh you changed the clock speed... TO THE MOON!
Chain[J6] has no core num in PIC
Chain[J7] has no freq in PIC, set default freq=650M Ooooooh you changed the clock speed... TO THE MOON!
Chain[J7] has no core num in PIC
Chain[J8] has no freq in PIC, set default freq=650M Ooooooh you changed the clock speed... TO THE MOON!
Chain[J8] has no core num in PIC

They miner is set to run at a fixed frequency so we can all buy some lambos.

Is this right? If so, at which frequency is it running?

Also, on the configuration page, I am only able to select between 550M, 600M or 650M. In another post in this thread you talked about making the changes on the advanced tab. I don't have that tab anywhere. Am I doing something wrong, or do I need to manually tweak other files through WinSCP?

Thanks in advance for the help.

actually i wanted to sort out why the chip temp decreased by ~10-15C, pls look at this:

highlighted S9 was patched with bmminer880 and increased freq from 625 to 675.

another funny thing is that hashboard temp is more than chip temp, how come? on non-patched S9 chip temp ~20C more than hashboard temp:

btw: what does the message exactly mean: 3 hours until mining?

I have one S9 acting erratic and dropping a board now and then. So im playing with the freq. It reboots a few times and starts hashing, but just lost all 3 boards now, so ill try another freq. 637 it doesnt seem to like at all..

It might need one of the versions with higher voltage. There is a possibility from luck of the draw your boards just are not that good.

hm. interesting, after installing bmminer880 on my S9 13.5T, put 650 freq and got 14Th, but funny fact is that chip temp dropped from 82 to 65 C, how is that? what is the stock voltage? is that consume less power now?

btw. respect for that Wink

Yeah 650 is 14th.

Hey taserz...thanks for doing this!

I have a mix of old and older S9 miners. One is an 11.85t, one 14t, but most are 13.0-13.5t. I haven't tried your process yet because I have new power supplies coming. They're modified 2450w HP units from Amity Labs in Oregon. I have cheap power in Washington State Grin

My question concerns the oddball miners I have. Is this just trial and error with the overclocking or do you have some specific guidelines for where to start with which machine? I'm eager to try the 920 or 930 packages, but of course I don't want to burn anything up.

Also, were you able to set up the software so each hash board can run a different frequency (mentioned in post 42)? There's some guy selling S9 firmware on eBay that claims to be able to change the frequency per chip! His "dev fee" is 1.8% though...

It is trial an error. It appears though keeping them all the same frequency is the base use scenario. The cards generally all perform at around the same rate sometimes there is one underperforming.

Also, I have run the 9.3v and 9.4v you need LOTS of airflow and low ambient temp. Stick with 9.2 max for most people

how to squeeze more out of it?
