What kind of hashing rates are we looking at for each mode?

Super Mode (1600w), Standard Mode (1300w), Eco Mode (800w)

I typically see 72-73c while running in balanced mode, and when I tried turbo mode for a few hours, it peaked at 79. I've just been using balanced mode for the better efficiency and lower noise. Thanks for the information.

I have an issue with one of my units randomly powering off. When it happens, the power switch light turns off, but if you tap the power button (not flipping the switch), the power comes back and the light turns on. I noticed if I just tap the power button while it's running (again, not flipping the switch), the power goes off and on. I'm assuming there is a defect in the power supply. Do I just submit for an RMA to have it replaced, or what is the best course of action?

I appreciate the input. I understand this works for you, but it doesn't actually tell me the specifics of the PCB max or Chip max temp, which I'd like to know. You must understand that 73 is quite cool for some silicon, such as current AMD processors (95) and most ASICs, and frequently ASICs go much higher than general purpose CPUs.

BITMAIN publishes data for their miners showing PCB max values in a range from 75 to 95, with Chip max values up to 135.

What is the max safe miner temp for the Apollo II?

@sidehack I am interested. I am still holding on to my old S1/S3 units in case you ever finish your upgrade kit idea.

I love the Apollo LTC. I picked up two "Batch 1" units during pre-order. I am planning to do the same with the newly announced BTC pre-order.


I used the futurebit.io contact form to propose such an option because I didn't see it on the pre-order page. I didn't even think to come here to suggest it directly to jstefanop. I am glad to see I am not the only one desiring such an option.

Having a full node directly on the miner provides miners with the capability to solo-mine without any additional hardware. Some folks consider this capability a big feature because it provides completely new functionality.

philipma1957 is 100% on target. He very tactful told you that you were asking the wrong question. Nobody faults you for not knowing why or how because you are still learning, but your question was like asking "will blending ethanol with gasoline make my car go faster?" Increasing a unit's hashrate post manufacturing through a software update rarely happens. When it does happen, the increase is typically anecdotal at best.

(1) Improvements to the voltage/efficiency of the ASIC chips could theoretically improve hashrate if the limiting factor is thermal. However, I believe that we are likely hitting frequency barriers inherent to the ASIC's architecture, but it is possible I am wrong.

(2) It is understood that functionality equates to features. This could lead to increased hashrate through increased frequency if that is the feature updated, but I would again state the likely frequency barriers of the architecture argument from (1).

philipma1957 is probably the most user friendly forum member willing to help newcomers. Having personally read a great many of his almost 30k posts over the last 6 or 7 years, I believe his statements regarding his gear and setup were meant to lend credence to his advice not gloat. You would do yourself a service to avoid expressing prejudice by listening a little more carefully and speaking a little less harshly. In case I am unclear, stop being rude.

I use multiple Raspberry Pi devices for mining and I see this type of error a lot. It almost always comes down to the SD card and/or the power supply. If it happens once a day around the same time, I would bet it is the SD card. The device is probably trying to run some cron job and the file systems takes a dive due to SD card issues causing a kernel panic.

Etcher does not require any setting changes.

I have not experienced any issues with using the reboot command. It appears to function correctly as intended. What were you trying to fix by rebooting?

Did you hash check the IMG or the ZIP of the IMG?

I am interested in getting at least two. Do you have a ballpark figure on the pricing? Will you be selling these direct or will you be using re-sellers only?

Micro Center SD cards are notoriously bad for this type of application. I tried on several occasions to use them for different Raspberry Pi projects, but I always had weird unexplained errors.

For example, I recently built a mining controller using a Micro Center 32gb SD card with a Raspberry Pi 2 Model B for my Moonlander 2 devices and the Raspberry Pi would have random kernel panics about once every 12 hours. I eliminated those issues by swapping out for a SanDisk card.

This is normal behavior for the RPi. It does not have a RTC and must therefore pull the current time from a NTP server. Applications that start before the NTP server is polled will show a time/date stamp consistent with your experience.

I am excited to see your next announcement.

I was psyched to see this announcement, but I had been hoping for the PayPal option you normally have on your website. However, I can understand why it is not an option with it being a pre-order and all.

Your power supply is too weak. At the very best, you are going to get 10W out of that power supply, but likely much lower. One 2PAC can pull over 10W depending on your settings.

I had 100% of my miners turned off for the better part of year. I know how it feels. For now, I am relegated to mining with USB miners for S&Gs. Such is life. Good luck getting everything up and running again!
