Alternate cryptocurrencies / Mining (Altcoins) / Re: Buying used 8 RX580 8GB miner on onda board with 1300W PSU need advice.

on: August 18, 2020, 08:26:11 PM

What do you think of the single 1300 Watt (EVGA 1300 G2) power supply that powers the whole rig AND the 8 X RX580 8 GB Sapphire cards? You don't think its underpowered? Is 1300W good enough for 8 GPU's? Stock? Undervolted?

Alternate cryptocurrencies / Mining (Altcoins) / Buying used 8 RX580 8GB miner on onda board with 1300W PSU need advice.

on: August 18, 2020, 06:39:13 PM

I am going to inspect a used 8 GPU (Sapphire RX580 8GB) mining rig with a single 1300 Watt EVGA PSU (I'm assuming its the 1300 G2). He claims he gets 29 MH/s per card. It is running on Windows 10. That sounds a bit underpowered for 8 RX580's The seller said the RX580's are all undervolted and bios modded, so that it is safe for the 1300W PSU. What are your opinons on this? Thanks for the advice. You might just be saving me from a costly mistake if this is not good. lol. edit he also claims he was able to get 50% undervolting on the cards (not sure if he's talking about bios mod or in msi afterburner.) He says he uses both. *Any other basic checking I should do to make sure its a good purchase? (I will verify booting, and hashing for a few minutes to makes sure it hashes correctly.

Bitcoin / Bitcoin Technical Support / Re: NOOB QUESTION. When using miner CLI do I put the receiving address of my wallet?

on: July 12, 2019, 09:24:11 PM

Thank you for your assistance! I ran my batch file with the BC1 address and it looks like it connected. It says "Pool message: Authorised, welcome to ckpool.org bc1xxxxxxxxxxx" Since it says authorized and not rejected, I'm assuming its a valid address for ckpool and that ckpool can accept segwit wallet addresses for payout? Here is the CLI copy paste: Connected to pool.ckpool.org diff 10K with stratum as user bc1qhafs8tl4nnuux0udhn05mmz8y3edn7zzfegpfs292k0xkm69gnfqpfl8 Block: b9ed9d81...

Bitcoin / Bitcoin Technical Support / NOOB QUESTION. When using miner CLI do I put the receiving address of my wallet?

on: July 12, 2019, 09:07:55 PM

I just want to make sure when I'm in a mining pool and using CLI CGminer that I'm sending the payout to the right place! For example: My electrum wallet has multiple "receiving addresses" they all start with bc1xxxxxxxxxxxxxxxxxxxxxxxx. Is that what I put in as the username in cgminer? For example, is this correct? If my receiving address is bc1XXXXX, then my bat file should read: cgminer.exe -o stratum+tcp://pool.ckpool.org:3333 --suggest-diff 128 -u bc1XXXXX -p x username "-u" is basically the entire receiving address in electrum wallet? And I can use any one of them since there are multiple ones? Thanks for your assistance.

Bitcoin / Hardware / Re: Just jumped in. Installed NewPac. CGminer repeating Stratum from pool detected

Quote from: 419mining on July 12, 2019, 05:05:55 PM syn00ack, welcome to the group! So you are hashing but your mining on nicehash and they are autosetting your difficulty to around 500M. From you post your best share so far was 6.87K so unless your work share is greater than 500M, you wont see a submission. But i haven ancient Radeon R9's and even Intel I3 CPU's that are hashing for me and giving me at least .0029 mBTC daily running on their NiceHash Legacy miner. The new GekkoScience NEWPACS are ASICS and have much more hashing power than the CPU hashing I'm doing. If nicehash accepts my old CPU's H/s hashes, why won't they allow my 22 GH/s hashes from the ASICS? Remember, my cpu's aren't actually mining, i'm doing their "sell your hash power" program, and I'm trying to get my NEWPAC to participate in that same program. They do have a webpage devoted to using your SHA256 ASICS and selling their hash power, so I know ASICS are supported in their sell your hash power program.

Economy / Service Announcements / Is the new GekkoScience NEWPAC USB ASIC compaitble with hash selling?

on: July 12, 2019, 08:28:54 PM

This is the new GekkoScience NEWPAC USB ASIC SHA256 miner. It works with ckpool.org so I know the unit works. However it doesn't seem to work with nicehash hash selling. I used this CL: cgminer.exe -o stratum+tcp://sha256.usa.nicehash.com:3334/#xnsub --suggest-diff 128 -u 3AJKKwAXidCh2ujrMgvbyUoYQomCJxTXXX.Newpac -p x 2>%LOGFILE% I can connect and I see it as a worker on my nicehash dashboard. However I just get repeating "Stratum from pool 0 detected new block" and 0 hashes. Anyone have any idea if this new USB ASIC is compatible with Nicehash stratum servers or did I do something wrong?

Bitcoin / Hardware / Just jumped in. Installed NewPac. CGminer repeating Stratum from pool detected

on: July 12, 2019, 04:14:51 PM

Just jumped in the bandwagon
I received the Newpac and followed the first few posts. Got Zadig USB to recognize the NewPac.
Ran the gekko cgminer with this command line:

Code:

cgminer.exe -o stratum+tcp://sha256.usa.nicehash.com:3334 -u 3AJKKwAXidCh2ujrMgvbyUoYQomCJxTJ36 -p x

But I just get "stratum from pool detected new block" and it keeps repeating that and nothings hashing.
Here is a CMD shot:
Any advice? Huh
