WOOF COIN

Since the beginning of the pandemic, pet surrendering rates have increased dramatically around the world. Waitlists for surrendering household pets have increased to a remarkable eight months as animal shelters and welfare organisations have seen an increase of 34% for animals needing help.

Typically, animal shelters are under resourced and under financed; relying heavily on donations and the volunteer efforts to assist animals.

This is where Woof Coin steps in. As avid lovers of dogs, we wanted to make a difference. Using the power of Proof of Work mining, we’ve created a coin where miners are contributing to the donation of money to animal welfare shelters. These shelters initially include the ASPCA who already have a cryptocurrency donation mechanism but with intention to expand to the RSPCA and other organizations suggested by the community. 

Our aim is to put animals first and we intend on developing ongoing relationships with pet shelters to help adoption.

With so much talk about connection problems, high ping, etc.  First I would try to use a wired network and see if that make a difference.  You can get even long network cables pretty cheap.  So even if ran temporary for a few day's to test I think it would be worth it.

After something simple would be to try SMOS ( https://bitcointalk.org/index.php?topic=1541084.0 ).  If it was a issue with windows this would eliminate it and you can test with running it off a USB stick. 

I would try those 2 things and see what happens.  Then start looking at hardware but hopefully one of two above fix issues.

Ye Ill definitely try that. Many ppl suggesting wifi, but the problem plugging it directly to ethernet cable due to my apartment layout is very...complicated. Weird thing is that the wifi is running 100% stable outside the mining and the weirdest thing is the randomness of this issue (it runs with 20-30 ms for hours and then just randomly it starts to lag like crazy). But IMO the high ping is not a cause but more like a symptom of something else.

It doesn't look like the power supply.
Your Corsair CS650M 650 W PSU got a total maximum power rating on it's 12v rail of 612W (489W @ 80%).
1070ti's maximum power consumption is 180W, multiplied by 3 = 540W (378W @ 70%).

You might be needing a new MotherBoard or SSD.
Problems in the Motherboard produces a lot of symptoms or some slowdown in the system, but overall, it's hard to detect.
What I'm suspecting is your SSD might be failing, freezing and some OS or Program related problems can be a symptom of a failing drive.

Tests you can do so far (one after another):
-Find a Hard Disk Drive for test and trials.
-Try your whole rig in a new Mobo.
-Upgrade to a bigger Power Supply. Preferably, 1000W for your 4 GPU.

1070 ti is 180 W at default, but all cards are running on 75% power, so that is 135 W (405 W total). If I understand it correctly, card always draws the power from the PCIE cable first, so if each 8 pin cable is rated at 150 W the cards shouldnt be even pulling any power through the risers, so there is still over 100 W reserve...as for the motherboard, I dont have any other motherboard, this is my only rig...and just buying new one for 150 usd without even knowing thats actually mobo causing this issues doesnt seem like a good idea to me. Is there any way to check that ssd is not behaving as it should?

Help diagnosing bizarre rig behaviour

Hi everyone, I built my first rig 1 month ago and its giving me headaches ever since cos I am unable to troubleshoot certain problems. I spent hour and hours of testing just to get to square one every single time.

Rig info: 5xGainward 1070 ti 8 GB, 2*Corsair CS650M 650 W PSU, Intel Celeron G3930 CPU, 4 GB RAM, Asus Z270-P mobo, ADATA 128 GB SSD, using 5x powered risers (009 ver.), Win 10, Virtual Memory set to 3000-45000 MB, WIFI USB stick. I am using latest NVIDIA drivers, Win updates disabled, running Nicehash legacy miner 1.8.1.6 and the newest V2 miner. On PSU1 I have connected 2 cards, 2 risers and mobo and on PSU 2 I have connected 3 cards and 3 risers. Each card and its corresponding riser is connected to the same PSU.

My OC settings: 75% power, 75 temp limit, +150 core/+650 mem, fan speed 60-70% depending on each card.

The actual problem: The rig starts to lag/freeze randomly during mining. I spent hours testing but I am unable to find any pattern why/when is it occurring. Some key points:

1) When it starts to lag, I get incredibly high ping (up to 3000-4000 ms) and/or multiple "request timed out", lose connection to TeamViewer and get some rejected shares. Sometimes I regain the connection and the ping gets stable, sometimes not and I have to manually shut the rig down. It seems the high ping is more of a symptom than cause of the problem though.

2) It appears to be happening with pretty much all algos, havent found any pattern in this.

3) Sometimes its running just fine even for 1-2 days (with occasional high ping/few rejected shares here and there), sometimes it totally freezes 1 second after I start mining.

4) It appears that when I am running 4 cards, the problems either dont occur at all or are less severe. It appeared at first that its the GPU n2 thats causing the problems, but latest testing suggests that its rly just random. Once all 5 GPUs are running it appears the issues gets worse (but again, randomly).

5) My hashrate seems normal and stable in the legacy miner and doesnt drop, even when then its starts lagging, however the hashrate drops quite a lot on the V2 miner in time (again, only sometimes, just randomly).

6) OC doesnt seems to be causing those issues, since Ive fiddled with different settings and even running on default the issues still persist.

7) Whenever I stop the V2 miner it resets the manual fan speed of all cards to automatic for some unknown reason. Legacy miner doesnt cause this issue.

8 ) My connection is completely stable with around 15-30 ms when I am not mining.

9) Sometimes when I restart my rig and open afterburner, it takes like up to 1 minute to load, sometimes its instant. Idk if this has anything to do with the issue though.

I apologize for the wall of text, but I wanted to list all the issues. Ill be glad for any help, hopefully there are some experience builders who have encountered something similar and might know the root of the problem.

One GPU behaves weird and hashes significantly lower

Hi everyone, so I have a following rig: 4* Gainward 1070 ti, Asus Z270-p, Intel Celeron G3930, 2*650 W Corsair PSU, risers are all powered directly from PSU (pci-e to molex), Win 10 pro.

Everything is running flawlessly except 1 GPU. Current OC settings are: 80 % power, 72 temp limit, +150 core, +600 mem, GPUs running at around 70-80 C.

I am running Nicehash legacy miner. During mining, the OC settings of the first card is constantly returning to default values when overclocked to the values above (the others are running fine). When I OC it back I see graphic artefacts on my screen. I lowered the OC of that card to +120/+550 and its running fine now, however, I noticed in the miner that the GPU0 (assuming its this one) is hashing significantly lower than the others (https://imgur.com/a/ZD8Jm). The hashrate seems to be behaving pretty weird though. For example if I am running Neoscrypt, 3 cards do close to 1100 hashes, but the "bad" one only around 750...other times it does around 1040 (which would basically equal the slightly lower OC settings). Same for the NIST5 algo (3 cards do around 54 mh/s each and the "bad" one 52).

I noticed a weird thing as well, when the PC is idle, something is putting stress to the GPU. When I open the afterburner, the GPU clock and MEM clock are on high numbers (like during mining), but on the other cards are down. The temp of the "bad" GPU (only when idle) is also like 15 C higher than the other cards.

My questions are:

1) What could be causing the stress on the GPU? I made sure I am using the integrated CPU adapter for my screen in BIOS. I am also running teamviewer to control the rig from my main PC, is it possible something has to be set there?

2) Is it normal that the temp of the cards are different during mining? (anywhere between 70-80 C).

3) Why are the GPUs going up to 80 C despite setting the temp limit to 72?

4) How is it possible I see graphic artefacts on screen when overclocking a GPU that is not set as default adapter for my screen?

I am sorry for longer post, but Ill be grateful for any help.

NVIDIA GTX 1070 Ti - differences between brands

Hi everyone, are there big differences between the 1070 TIs? The only one I can get that is least overpriced in my country is the Gainward (this one http://www.gainward.com/main/vgapro.php?id=1008&lang=en). The only other one is MSI Aero for around 600 usd (which is sold out everywhere here), all the others are like 650-700 usd lol. Should I go for the Gainward? Are there significant differences in hashrate between different brands? Thanks in advance
