I have noticed, that adding more GPUs to my rig, lowers the sols per GPU.

3 x 470s = 15 sols per instance.

5 x 470s = 13 sols per instance.


That sounds plausible, because more and more GPU's saturate the CPU cores, so CPU throughput becomes the bottleneck. Especially with nvidia cards, CPU load of this miner is quite high.

I wondered that.  cpu at ~60%.
PCI bus maybe?

Oh, scrub that.  It's back up to 15.  Must have been something else.

can anyone post a block explorer for Zcash? Now the pool says paid but I don't see anything pending in my Polo account. Just want to make sure it's in the block explorer.

I'm not seeing anything in polo either.  Only block explorer I can find is testnet.

Guys. How to change GPU fan speed in ubuntu 16.04 ? and frequencies and voltage?

Code:
apt-get install fancontrol
pwmconfig

and then I wrote this script to set the speed:

Code:
#!/bin/bash

SPEED=${1:-200}

find /sys/devices/pci* -name '*pwm1' | while read line; do
 echo "$SPEED > $line"
 echo $SPEED > $line
done

increase value in /sys/class/drm/card0/device/hwmon/hwmon0/pwm1 (default on mine was 35)

i.e. set fans to 250 (255 is max)
Code:
sudo echo 250 > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1

additional cards change card# hwmon#



Found an alternative way:

This doesn't work for me.  "hwmon" is missing, and my GPUs are getting too hot.

Does the fanspeed setting work on Linux? Doesn't seem to do anything on my 470's, and the fan is too slow.
The new AMDGPU-PRO Driver for Linux doesn't seem to have any console app to adjust it.

It was written in C# .NET, hence mostly in Windows. I hear that it will take additional lines of code for C++ and also I hear they just included another Chinese dev who will code in Ruby. But hey at least most code are original.

C# .NET is multi-platform. Runs fine on Linux, Android, X86, X64, ARM etc.  If it's the desktop wallet your talking about, then that might be an issue depending on the UI Toolkit.

Holy cow!  Alibaba.  Shocked

Why isn't everyone partying?  Alibaba is the biggest marketplace in the world.  Bigger than ebay and Amazon.

"There has been some way to measure success in the Service. British Leyland [car manufacture] can measure success by the size of its profits. However, the Civil Service does not make profits or losses. Ergo, we measure success by the size of our staff and our budget. By definition a big department is more successful than a small one."  -- Sir Humphrey Appleby

Government agencies have to fight for their budgets. The only way to survive, and expand is to lean on politicians.

The NSA and GCHQ are under threat, because of the ever increasing use of encryption, which reduces their roll, and thus budget.

This is about jobs, and expense accounts. What better way to keep the good times going, by scaring people. All part of the toolkit to manipulate politicians and popular opinion.

So if I understand correctly, the British prime minister wants to ban every PGP, P2P encrypted message/data transmission application/service from UK?
How exactly is he going to do that?  

In the same way you ban drugs.  You cant actually stop people using/distributing drugs, but you can make it illegal.

So whilst an individual might take the risk, a legit company would not.  Google would have to block apps in the UK play store that don't comply.

Unfortunately most people haven't got a clue, and anything that will "stop terrorists" must be a good thing.  In reality, companies will follow the profits, even if that means having to comply.

Listen to one of the government advisor's.  WARNING: This will make your blood boil.

It is the PSU. The 1500uF green capacitors leak because of unstable PSU. They can be removed by hand as they are not needed. Just pull them out.


I pulled my green caps out over the weekend.  Got it down to 10 minutes per unit, from opening the lid, and screwing it back up.
I'll post details on how to do it on ecointalk when the psu's are available.

Bogart I am not doubting your network, I am assuming you replaced the network cable on the faulty machine, and changed ports on your switch already. Also, set up a ping watcher for the machine and watch the results for when it falls off.. this will tell a lot.

There is also a Windows tool you can use, to listen to the multicast packets that the Prospero(s) send out.  It's used for communicating with Prosperos in a datacenter, but handy for diagnostics.  http://ecointalk.net/topic/1182-multicast-address-grouping-your-prosperos/

not actually mining, they're doing: "cgminer --api-listen --api-allow W:127.0.0.1 --minion-freq=1000 --benchmark"

Yes, this.

There is a growing list of documentation here http://ecointalk.net/forum/78-support/

@elemental there is a web page you can go to, to simplify finding the IP address without using the LCD  http://prospero.blackarrowsoftware.com/ (although that's not much use to you now).
As there were lots of documented problems in getting the LCDs for the Prospero, it is indeed behind the curve in terms of being set up ready to use out of the box.  It's supposed to show you the stats screen after boot, but instead you have to activate it manually.  It was discussed here, for the X-1 http://ecointalk.net/topic/1221-logic-ethos-lcd-wifi-x1s-shipped/?p=15968

It also sounds like you need to update the software.  See http://ecointalk.net/topic/1237-v1-updating-problems/

Hardware wallets are the future.  I love my Trezor, but it's not perfect.

The perfect HW wallet to me, would be credit card sized, with an e-ink display, keypad, and RFID.

It would be powered by the RFID, and you can stick it to the back of your smartphone.  Whenever you stage a payment on your phone, you turn your phone around, and type in your pin. The card would then sign the transaction, and hand back control to the phone.

It would also work on shop terminals, so payment would be as easy as holding the card over the shops terminal, and keying in the pin (or or not, if the transaction value was small).

It would also be your key to online sites.  Put your phone/card onto a USB RFID reader plugged into your laptop/computer.
