It does generate 580MH/s and higher. see screenshots
Professionally refurbished
Professionally upgraded to L3++
As you can see in the picture, the machine runs
582.12 MH/S @ 425M frequency 47-49 chip temperature.
Please notice, the hashing power changes, it will vary. the most important is the air flow.
So I do not guarantee you will always get same hashing power.
Higher frequency does not mean higher hashing power.
You need try different settings
My experience 425M is the most
suitable
.
I always keep my machines under clock.
The standard L3++ frequency is  580 MH/S @ 450M frequency, the standard L3++ is 504 MH/S @ 384M
Please notice, the hashing power changes when temperature changes. my miner can go faster but I do not want to overclock it.
Also, it is advised to remove the front fan to get better air flow, you will need a fan simulator to do that. I will sell some later.
I am converting miners to Oil cooling, so the computer can ran to max 720 MS/s without raise the temperature. (not included in this sale
I always keep my chip temperature below 50 degree C.
I will reduce the frequency during the hot day time.
Guaranteed Not DOA and no return
The power supply is a 240 1850W after market power supply. so you do need 220 outlet which is not hard to install.
110v outlet will not power it up.
I will have some 110-240 power supply later.
if you have the factory 110-240v 1600w power supply, you still need 240 because 110 will only give it 800w, it will not give you the extra harsh rate.
be
careful
adjusting the
frequency
, make sure you do not burn the chip.
No DOA (dead on arrival) is guaranteed. No returns though.
When power on, wait to see the harsh rate, you have to refresh the browser to see the new harsh rate, the pool page will react faster.
That is all I can tell.
contact me for any information. I will try my best.
thanks
