I'm struggling here, can you provide more details on how you overclocked it? I changed what I though was the frequency from 400 to 500 and my hash rate dropped from 200G to 50K. I have a GekkoScience

For a start, it would be better for you to post this in the Compac-F thread...
If you read through the 1st few pages you will probably find the answer to your issue. #1 cause of problems is using an outdated version of cgminer or the version that came preloaded on a Pi (which is the wrong/hacked version).

Increasing the frequency of a Compac F or a Newpac requires to provide it with more voltage, this is done by changing the voltage setting via a screw on the back of the stick, see the dedicated thread from Sidehack https://bitcointalksearch.org/topic/gekkoscience-has-a-new-stickminer-that-does-300gh-5355470
It is also necessary to have a hub able to provide the 2.5 Amps or more necessary, personally with the Gekkoscience hub (v1), my 2 Compac F are O.C at 570 Mhz and the Newpac at 300 Mhz.
I burned out in 2 months the previous Gekkoscience v1 hub too, by being a little too demanding on the O.C. level, the sticks were at 620 Mhz individually cooled and worked well for 3 weeks before the hub failed, so be careful anyway.

I have had the same problem. I ended up changing the frequency on all the miners listed. I use the configuration file and make sure that all other copys of the file are deleted. Although I have cg miner on my computer.

Thank you for the reply, but after editing the script I'm still mining at 100. I dunno if it's bc I'm running on a raspberry pi, but yeah....still mining at the 100 freq.

Where did you get the version of CGMiner from? I ran into a similar situation with a PI4 that came from a company with CGMiner pre-installed.

The only solution was to reinstall Kano's latest version of CGMiner which then worked.

cm use --gekko-newpac-freq 200 --gekko-start-freq 200 --sugg....
will work.

I am a total newbie with this and was hoping someone could help. I am also having trouble in cgminer trying to change the frequency. I have changed every instance I could find in cgminer in order to overclock with no luck.

Linux since 1997 RedHat 4

gekkoscience newpac is an ASIC miner - using S9 ASIC mining chips.
It just happens to be a very small one.
Though it would only make you at most about $30-$100 a year before subtracting costs of buying and mining.

Is it profitable for you? How long have you been doing it? Just curious.

He is not mining with rasberry pi, he is using it as a control board/ brain for the USB stick which does nothing but "hash", so you either run Cgminer on your PC or put it on a rasberry pi, the latter of course is more convient and consumes less power compared to leaving your PC on 24/7.

This whole set up is far from profitable, all of these cute and tiny USB miners are not profitable, you use them for fun, or to play the solo lottery or just to get the hang of how mining works, if you are interested in mining you need to learn about ASIC miners, those are noisy industrial-grade machines, and they happen to go up in price by almost a factor of 10 in the past couple of months.

I am running cgminer on a rasberry pi4 (linux).

Sounds like you got your question answered, but I'm curious as to how you're mining. You're using a Raspberry Pi to mine BTC? I'm absolutely no expert on mining bitcoin and rarely post in this section because of that, but I have become interested in mining altcoins and oddities like the Gekkoscience devices--but I've never heard of anyone using a RPi to mine btc before.

I finally found and changed the frequency in the cgminer.conf file...............

I am running cgminer on a rasberry pi4 (linux).

I've been using the following script for several weeks now with one to four (4) newpacs mining successfully.
"cgminer -o stratum+tcp://stratum.(my mining pool address):3333 -(user name) (password) -p x --suggest diff 1 --gekko-newpac-freq 100"

Yesterday I changed "gekko-newpac-freq 100" to "gekko-newpac-freq 150" in the above script.

And I saw no change in frequency..... It stayed at 100.00 MHz and I waited for it to change for 20 minutes.

Currently I have four (4) successfully mining with the script changed to "gekko-newpac-freq 150" all Four (4) show a frequency of 100 MHz with 22 plus change Gh/s.

It is now 18 hours later and I'm still mining at 100 MHz.

I've asked the folks on the Gekkoscience area but I thought I'd try here as well.

Could there be a file in cgminer that is setting the frequency to 100 MHz and not responding to my script?

Any thoughts?
