Topic: Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux) - page 686. (Read 3839163 times)

There is a rather amusing flaw in Claymore's miners. With a small script you can vastly affect the devfee. If you have a script look at the log file to detect certain events, it can then trigger other events. So let's say your script searches for devfee mining start and adjusts your core and mem timing, then when the script sees devfee mining stop, your script then reverts the core and mem, it doesn't mine very much to the devfee address. It works with all his miners I've tested so far. A rather small but potentially expensive flaw.

Has anyone benchmarked a R9 Nano with the latest version?

Also, any news on a linux release?

Are there any miners you can use to mine zcash?

Thank you before hand, my friend.

Agreed - I have two 290x Sapphires running a steady 111 on v2.1 with -i 2 set and no over clocking.  The guy knows how to squeeze the efficiency.

The card is too old. It is not supported in this miner.

I recently had that and a driver reinstall cured it

Please i need help

GPU: AMD Radeon HD 6700
Catalyst 15.7
CPU: AMD Phenom 8320
16GB RAM

im getting this

GPU returned incorrect data! 43#####

any idea?  im running 280x toxic

I have the sapphire 470 8gb, around 40 without modded bios....Trying to find a modded bios that works but Im still getting a blue screen...

Going to keep lowering to around 2000 and see what happens.

Probably just the mobo. No big deal really. You can get a used one of those for 30 bucks on ebay

http://www.ebay.com/itm/Dell-Precision-Workstation-T5400-Dual-Xeon-Socket-LGA771-Motherboard-/322304684309

Regardless if you do just replace the mobo, or if you get a newer mobo/cpu/ram combo instead, I would also throw that PSU out and get a good 1200W Seasonic or EVGA or the like.

Honestly guys im tired, a little help would be much appreciated..

All I want is the best working Modded Bios for RX470 8Gb card.

Ive tried to play with the settings but guessing is not helping..

Anyone?

Claymore´s Miner is only for Pool Mining and I cant find Stratum Solo Mining Pool for zcash at the Moment.
Wait about two Days. If all Rig Owners switch back to ETH due better profit, then Time is come for Solo Mining ZEC with much lower Network Solution Rate.
Only Linux Node for CPU mining available yet.

Congrats Sir! You have smoked your mobo by using the PCI card without perf power from the PSU. No way iot could handle the vid card power draw. Nicely done

Nope my friend, you got me wrong. Had 2 290x running with the PSU connection. After I fired them to hard, something got killed. Did not get them running again. Black screen before or after login. A small old simple PCIe VGA works but only in std. mode. Thats why I think I grilled the PCI.

great ,thanks man for perfect tool.
and does Claymore support mining in linux just for solo in local but not in pool

Congrats Sir! You have smoked your mobo by using the PCI card without perf power from the PSU. No way iot could handle the vid card power draw. Nicely done

1050W and ZEC V2 took about 15% load.

Am thinking it's the PCI Slots. Have a small PCI card (wo PSU connection) running there in 1024*768 mode, when I rise the resolutuion I get blackscreen. Any doubts?

...and it took 5 months until I got greedy.

Yupp, had a close eye on the heat. Usually in the 70s (°C) max 80. These cards are said to be rated up to 95°C. Did not rise power, was only adjusting speeds.
