Been running for a week successfully at 400MHZ ambient around 0 - 10 C....

Lets see what this miner is made from and clocked to 425MHz...

Everyone whining about coupon ... I have 1 for 40usd....

2 hours to sell it or i order it for myself....

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?

The 5f05 is 393MHz chip frequency and somebody calculated that in a normal setting it is the most efficent frequency as HW errors are under 0.1% ... but it all depends on your ambient and how well you have ventilated the device...

OK, I have them on my balcony ambient now at 10~12C. So I do not dear to go over 300MHz...

I am measuring with a laser temperature meter, errormargin of +/- 0,05C.

Now do I dear go for 310 MHz? Can the power regulators, capacitors etc. take it?

Working the tube miner hard at 300MHz results are great, ambient at 16 and 1250w power and the powerdraw from the wall is 1000 W

Chip temps measured at 45C

Ok, I'll try and report back tomorrow

0.9J/GH = 0.9W/GH/s
850GH/s * 0.9W/GH/s = 765W


So...

I got my tube and put a 105A 1250w powersupply to it, with individual cables to every pci power connector (total of 8 cables). Ambient @ 16c and the results so far at 290MHz has been very promising as seen in the picture, also I have push - pull fan configuration...

Have anyone clocked it to 300? and what are the hw errors at that rate?

I tried to find this out by searching the forum but didint.

What is the power supply requirements for one 800GH/s tube? is 85A enough (1000w, 80+ PSU), or do I need more and how much?

How bout overclocking, how sensible is the device to HW errors and temp?

I have powered it with 1pcs of 6pin and then I have a molex -> pci 6pin adapter with 2 molex inputs. The cables get a bit warm but it works fine... But I would really recommend that you power the unit from 2 different cable sets, like I have.

1 - 6 pin pci adapter
2 molex --> 6 pin pci adapter and both are from their "own" wiresets.

Hi sorry for the delay in my answer.

I have a power meter before my psu, and the power draw seems to be 450 ~ 457W. The powersupply is an Fractal Tesla 80+ 650W and it seems to work fine with the miner, with all the added cooling fans, and with added cooling heatsinks over the chips, condensators, and voltage regulators.

I used the following picture to analyze where to add extra cooling

Also I rotated the setup of the miner so that the aluminium standard cooling sinks are on the outside with fans blowing into them at full speed (yes the noise is terrible)...

Update 20.9

Seems that 412.50 MHz is too much, 2 chips went offline and 406.25 MHz seems stable... All the hassle for just ~3GH/s... well you win some you lose some...

e: HW error rate seems to be around 0.25% ... Not bad at all...

Thanks, I tried to push the miner to 425MHz but 2 chips failed immidiately, or reported that they do not work. So I setteled with your settings 406MHz and so far it seems stable with temps @ 24C and 25C, ambient 17C / hw= 0.22% ...

Would really like to know what is 410Mhz and 415Mhz...

Hi everybody (my 1st post)

I have an Antminer S1 and I tried to find the right frequency settings for over 400MHz clocking. I have a seriously modded Antminer pushing at ~205GH/s with an HW error rate of 0.025%.

I know the 400 setting is

option 'freq_value'   '4f81'        #400M
option 'chip_freq'     '400'
option 'timeout'       '35'

but I am looking to overclock to eg. 410MHz --> 425MHz --> 450MHz

Could someone tell what the freq_values for these settings would be.

Much appriciated
