The CompacF is the most powerful USB miner ever made - that actually turns a profit in most cases. This rig includes active air cooling on each miner. Those miners can peak much higher wattage compared to the older version, the NewPac miner. It is up to 5 times more powerful than the NewPac miner as well. It is unlocked for overclocking (Voids warranty). It features a single 7nm technology BM1397 chip.
*Made in the USA.
**PRE-ORDER** available now for the 2nd Batch of the Compac F - shipping in about 2-3 months from order date.
** Some programming with Git is required on Linux to be able to mine on this new USB Miner. However, you can add to this kit our Raspberry Pi computer with Compac F preinstalled for easy beginner mining. Git file available here - https://github.com/kanoi/

These compac F miners work. The issue is POWER. Even the provided 7-port hub stuggles to power the miners (in overclock state).
The Compac F requires a hub WAY OUT OF SPEC. Hence nearly impossible to find one.
My personal experience with the Compact F is a max clock range: 450-490 MHz. Not sure why I get varying results, but its a power thing.
The listed overclock of 400 will not get you to ~334 GH/s needed for a total (3 device) 1 TH/s.
If anyone is aware of a USB hub with over 3.1 amps per port - LET ME KNOW.
It’s a perfect little desktop Bitcoin miner. Took it out of the box and haas it minning in 20 minutes. Love it!
When I first ran cgMiner with the present script I was maxing out at 300-400gh/s. I tried adjusting the --gekko-compacf-freq 400, between 425-800. I have played with every setting and the best hash rate of an average of 650 gh/s has come from the freq at 500. As cgMiner recalibrates as it runs; Card 1 always settles at a freq of400-475, card 2 freq at 320-380, and card 3 freq at 380-420. Running above freq 500 drops to about 350gh/s average rate for all three. Also, I changed from using the installed preset cgMiner to a different GitHub version and it added a 150gh/s increase to give me the average of 650gh/s. Very few spikes above 750gh/s and none below 500 gh/s with the above changes. Overall it works but not at the rate the cards claim to. My average over 2 weeks has been 650 gh/s, not 1TH/s +.
I spent more time unpacking than making it work. The CompacF kit + the Raspberry CPU made the magic. I’m mining Bitcoin. The whole exercise was productive and as a learning experience was exceptional. The product came so well packaged and protected and the tracking was easy.
Bitcoin Merch is my go-to for new mining kit. These new Gekkoscience USBs are the equivalent of something like 10 Newpacs!
