Thank I did the same now. set the port to -3333 so that miner can't be changed. The app, Claymore/optiminer Monitor seems to work fine when I connect to my VPN via the GSM network. Better than using TeamViewer, that is for sure. I wish it had a widget or alarms but as the VPN will disconnect frequently when coming it is better not to have alarms.

Not that keen to setup port forwarding at this time. I have been hacked before so VPN provides an additional layer of protection.

is there a way to monitor my rings remotely from my phone? at this moment I use time viewer to periodically log into a loos standing pc on the netwerk. The network is firewalled to reduce the chance of being hacked so connecting directly to each rigs is not possible.  

I see there is an app on play store but not sure if it safe to install and connect to my rigs

Do you think these spikes can be the reason why my rig freezes? I will describe my problem a little.

I have a 7970, a 280x and two fury nitros. During the last couple of weeks I have been trying to run my system stable with no luck. Freezes can happen at any time after starting to mine. Sometimes minutes, sometimes hours.

Rig specs: Asrock 970 extreme4. Sempron 145. 8GB ram. EVGA 1300 G2. Sapphire 7970 ghz edition, sapphire 280x vapor-x, 3x sapphire fury nitro OC. Tahiti cards undervolted on bios, fiji cards on msi afterburner. No OC on furys. Win 10. 12.6.3. CM 11.1.

First I changed all risers to v6 ones.

Next I upgraded the processor to athlon x2 because I noticed that I was getting less hashes when MSI afterburner was on and I thought the system would be more stable.

After a couple of days more I changed the mobo to asrock h81 pro btc with celeron 1840.

Still no luck.

I thought that the power was insufficient so I added a corsair rx1000 linked with an add2psu device.

No luck, freezes persist.

Changed EVGA to corsair hx1200i. This psu is powering mobo, raisers and tahiti cards.

Nothing changed.

I stopped undervolting. Still same freezes.

One fury died the day before yesterday. No fans, not detected in win 10, not detected on ubuntu, mobo not booting when the card is alone.

I changed risers again to the furys.

I used separate cables for each riser.

I powered the offending fury card with one cable for each connector. Still the same.

I tried catalyst 15.12. Same effect.

Sometimes I see 511 degrees in the fury card on CM log prior to freeze, sometimes it just stops hashing without any error and the watchdog doesn't restart the miner, sometimes all 4 cards go to 0.000 hashing without any error, sometimes after gpu reported incorrect temperature 511°C.

I'm already out of ideas.

Any hint, anyone?

Edit: typo

I don't know preciselly bit I think it is something from 100w to 120w

I managed to lower voltage to -96 in afterburner at stock clocks 1256/1750. It is showing me around 1012 mV. If I lower it in AMD Wattman I can lower it to at least 985 mV. At 975 mV it is unstable. I get 243 h/s on -i 8 and modded bios.

Hi everyone!

Please help me with advise. Will it be enough to put 1000W PSU ( Chieftec APS-1000CB ) on 5*RX 470 4B with AMD FX-4330 CPU + 1 SSD ?

People say that this GPUs can draw up to 200W on some peak consumption. If it is so , then PSU is not enough for that RIG ?

Also Asrock H97 Anniversary is really good
I use both but i prefer the H97

Be carefull, ZEC profitability is droping fast....

EDIT: Ok, went back up 

Dwarfpool hasn't made a payment for 2 days now... WTF?

Best I've gotten is 222 so far so I'd say your good.

So what is regular speed with 280x with 1100/1500 clocks ?

Im getting 211-221 H/s on ver.10

Is it ok ?

I have HD7990's which are two HD7970's. Thet run at 255-261 SOL/S per GPU

Claymore detect them as 280x which is incorrect but I don't think it matters.

Problem is that the reported sol/s and the pool differs by about 16%.

Not sure why

They all are more or less - same. Some more luck today, some tommorow but newbies always know best...
