After 6 months of learning about immersion and trying out an S9 and T17. I have finally got an S19J PRO 100T immersed. Slightly overclocked to 105T, with chip temps 65-75C and board 50-60C.

Tell me what you think!

Hello,
I rebooted, reset, but it keeps restarting. I'm using ASIC.to firmware. Autotuning is off. It's been working for 3 weeks straight.

Hi,
How do you compare a T17 chip temp 80C to an inlet temp of S19? Is it even comparable? I'm asking this to get an idea on what my S19 temps be like when I get one. I currently run a T17 immersed with chip temp 80C and board 50C, fluid temp is 40C.

Here's my setup:

- 22x24 wood stove heat exchanger https://www.outdoorfurnacesupply.com/22x24-water-to-air-heat-exchanger-hot-water-coil-outdoor-wood-furnace.html

- 40 LPM 1/24hp March pump (ignore the pump in the picture, it has been replaced with this) https://burtprocess.com/march-0135-0037-0100-series-mdx-magnetic-drive-pump

- CPVC hardware

-metal tank with two champers and flowplate

- Shell Diala s4 ZX-i dialectic fluid

I got a T17 40T for testing, and I can't say I'm happy with the temp readings. It's currently hashing at 36T dawing 1.9Kw.

Temperature readings are as follows:

- max chip: 85C

- PCB: 60C

- Fluid: 45C

- Ambient: 32C (89F)

My ambient in other rooms is no more than 24C (75F). Could the reason be the unshrouded fan? Because I can feel warm air coming out of the sides of the fan. I opened the window next to with to try to get the hot air out, but it always has been in the 30-32C range.

I asked around and it seems people are complaining about T17s temp sensors being excessively high either air or immersed. Am I correct to assume an S19 would do better with this setup?

I flashed ASIC.to on my T17 and it's giving 33-36T but it keep restarting for 2 days straight. here is the log;

please let me know

Hello,
I could not wrap my head around how weird this is.
I have an immersion setup sized for 6,000Watts. I got an S9 to test things out and was able to hash at 16T drawing 1.4kW with chip temperature 65-68C. Never exceeding 70C.

I felt confident enough with my setup to get a T17 42t, with Braiins installed, it's currently sitting at 1.9kw with chip temperature in late 80C.

I don't understand how a 1.4kw S9 is 65C and a 500W increase in a T17 shoots chip temperature to almost 90C!

Ambient temp is 30C, fluid inlet temp is 45C.

Here is an image showing both settings for S9 and T17:



Here's my setup https://imgur.com/a/LFZIk8E

Could it be something about T17 sensors? My setup is oversized for this kind of power consumption!

[gpg --armor --export KEY_ID | base64 -w0]

Hello,
I know I can export my key through the GU suite, but can someone please breakdown this command for me:

gpg --armor --export KEY_ID | base64 -w0

the w0 dosesn't get executed, what does it mean?

Thanks!

Hello,
hope this is the right place for this kind of post.
So, There is this project (altcoin) called The Origin Protocol, their vision is a decentralized peer-to-peer eCommerce platforms, to compete with shopify. This product is called dshop (https://www.originprotocol.com/en/dshop). They claim to achieve this by combining IPFS ,to pin the site's data, and Ethereum to store those IPFS hashes and send them over the blockchain to process orders/receive customer's informations. All customers' information are encrypted with GBG and can only be decrypted by the dshop owner to view the details and send the goods!


Share your thoughts! Has anyone tried deploying their own dshop? tutorial: https://github.com/OriginProtocol/dshop
