I have seen more of the same article on different websites, but that is about the image I made before this one, where indeed only the values 1000, 1200, 1280, 1300 and 1400 were accepted.
In this version the values 1000, 1080, 1200, 1220, 1240, 1260, 1280, 1300, 1320, 1340, 1360, 1380 and 1400 are accepted.
However, this time it does not work to simply change the index.php file, you need the entire image: https://mega.co.nz/#!GNMQAIrb!IjkpJvS36O29AfOKc_jR9aezdH5yZnHMiGY5mIGyypk

It can take 1220Mhz as effective? So its REALLY set as new frequency and not defaulted to 1200? Which cgminer binary is that? Thanks
Yes it REALLY sets it as a new frequency! Look at post 42 (the first two frequencies, I only have an A2 mini). This was 1320Mhz, it takes that, but it takes the rest as wel.
1320 was always possible as far as i remember. did you try e.g. 1220?
Just for you BakSAj

Good news:
The miner can send work to 8 boards, I only have 2.
But as you can see the 1320Mhz is accepted by the miner
I will test some more, but this looks promising

how can i edit IP of machine on windows? i cannot get ot my miner since its on 192.168.1.XX and i need it at *.0* 
You can change that on the PI. Ssh into the PI and follow this tutorial: http://www.penguintutor.com/news/raspberrypi/linux-static
For Ssh follow this: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-6-using-ssh/ssh-under-windows
Hope this helps.

thanx worked!

You are welcome. If you like to split your additional income because of the overclocking
you are of course free to do so

Hi Emdje,
If I were to over clock my A2 5 module 75mh/s miner to Max 1300mhz. Would it be fine to run it, directly under an air-conditioner sitting on 20 degrees Celsius, without making any changes or adding any heatsinks etc to the miner?
All I will do is keep the lid or top of the miner opened.
There may be a way to setup the miner and the wall mounted aircon, so the aircon, points directly at the intake fans, on the device.
Although will aircon air, blowing over the top style cooling, be just as effective?
Thanks again for this great IMG file. Appreciate your work greatly.

I'm not sure I would take the lid off. Essentially you will be letting air go up, yes hot air goes up but the airflow then would not be making it as easily to end of the blades.
Be careful if you are overclocking and thinking about doing things such as leaving case top off. Most likely it would be better with case top on and extra cooling going in from front or adding extra exhaust. And of course temperature of room is a factor.
Thanks for the advise mate. That sounds very logical. More reason for me to set up the office to suit the miners needs. keeping a close look at the temperatures of each module.
Thanks again
Hi I have been on a holiday, but here I am agian.
My advice is the same as quoted above, taking the lid of destroys the airflow. The blades can take a lot of heat by the way, mine has run without any fans for 10 minutes on 1300 MHz before I realized I had not turned them on. And my A2 Mini still hashes perfectly: https://www.miningrigrentals.com/rigs/3166
Hi guys, I know this is totally off topic, but what's everyone's preferred mining pool for they're ASIC innosiliocon Scrypt miner?
We have A2 units running in an 80 to 85 degrees F environment clocked @ 1300 with no problems . Innosilicon A2 is the best miner made to date. When they release their kernel you'll be able to get about 118 MH/s from these.
Do you think they will ever release their cgminer? From what I heard Innosilicon is done with A2s.
We know of people that know people that can obtain it but it may take a month or two.

We have A2 units running in an 80 to 85 degrees F environment clocked @ 1300 with no problems . Innosilicon A2 is the best miner made to date. When they release their kernel you'll be able to get about 118 MH/s from these.
Hey peeps, whats the maximum and also average temparture you want your individual cores to sit at, when overclocking to 1300mhz for example?
I was chatting to afew mates, they think maximum 60 degrees celsius. And thats cut off point. So therefore, an average of 45 degrees celsius wouldnt be too stressful on these asic cores would it?

Hi Emdje,
If I were to over clock my A2 5 module 75mh/s miner to Max 1300mhz. Would it be fine to run it, directly under an air-conditioner sitting on 20 degrees Celsius, without making any changes or adding any heatsinks etc to the miner?
All I will do is keep the lid or top of the miner opened.
There may be a way to setup the miner and the wall mounted aircon, so the aircon, points directly at the intake fans, on the device.
Although will aircon air, blowing over the top style cooling, be just as effective?
Thanks again for this great IMG file. Appreciate your work greatly.

I'm not sure I would take the lid off. Essentially you will be letting air go up, yes hot air goes up but the airflow then would not be making it as easily to end of the blades.
Be careful if you are overclocking and thinking about doing things such as leaving case top off. Most likely it would be better with case top on and extra cooling going in from front or adding extra exhaust. And of course temperature of room is a factor.
Thanks for the advise mate. That sounds very logical. More reason for me to set up the office to suit the miners needs. keeping a close look at the temperatures of each module.
Thanks again
