Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[stoon]

Set the following environment variables, especially if you have 1-2GB cards:

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100


where i must put that
at start bat file???
or at some new bat file??

any example?

Have you read the very first page of this thread. I don't want to sound mean but sometimes you have to do more reading than you would like to figure things out yourself. That's part of making a hobby interesting - learning new things! Everything you have asked has been said many times before in this exact thread.

i must write

set
or setx??

"setx" will set those parameters permanently.

in start of bat file like

set GPU_MAX_ALLOC_PERCENT 100
set GPU_SINGLE_ALLOC_PERCENT 100

here are the wattage usage i checked with energy meter
http://www.ebay.com/itm/New-TS-1500-Plug-in-Electricity-Meter-Electronic-Energy-Meter-LCD-Energy-Monitor-/121962476226

card is rx470 4g OC


5X RX470 ETC+DCR modded bios 1100/1900 powerlimit 25+  950 watt
5X RX470 ETC+DCR stock 1216/1750                                  805 watt
5X RX470 ZEC                                                                885 WATT
5X RX470 XMR                                                               760 WATT


is that possible lower the power consumption?

Stop overclocking. You are wasting power for minimal gains.
My rx 480 rigs using 5 GPUs and my modified bios with 1100/1895 run at 215-220sol/s on each gpu and use a total of 680-700watts

NV 1080 reaching now 385 sol/s ; 1070 - 350sol. ( 2% devFee).
.. so where the AMDs are going...

Hi to all

why my share found very very hight  327ms-1200ms--120ms--its Different why???

My memoory rom 4GB---and--cpu g3240 3.1Ghz..motherboard b85 asus

im tested all connection in pool drawfpool...but not fixed...what are you doing ...this see picture

in realy this problem in flypool i have......my problem where???

My god, those poor fans.

my fans are at 100% does that make me a murderer?

There isn't really much benefit to running cards below ~65-70.  So it is not worth spinning fans really high to get temps in 50s.  For Eth or Zec with undervolt, 30-50% fan should be fine. You may get slightly higher extreme clocks with lower temp, but not worth killing the fans.

I have been running my gpu miners to be at or below 60c since r9-280s with fans at 65-100%(summer) and have never had a fan or gpu burn out. They are meant to be running hard and the cooler the temp the longer the gpu lasts. If you run your card on the warm side around 70c , take it out, smell it and look at any 's at spots, around the chips. You will find them and that's a sign of too much heat not expelled properly around the card/ic.

Hmm. Maybe I'll power up my gtx 1060 rigs. Hehe.

wow nvidia catching up.. i think AMD can still squeeze more H/s..i played civilization 6 with my fury, still with 260 H/s   and if i'm doing web browsing and multitasking it feels like there is no mining happening in the background (no lags with 330-340 H/s).

Can you help a lil ? I have a error like this WATCHDOG: GPU 0 hangs in OpenCL call, exit . In 6x470 4g rig I'm not having this error (last catalyst + 1200w bronze evga psu) but in other rig which have 5 gpu 3x 390 2x 390x with cata 15.12 and 1500w power supply I'm getting this usally after 1 or 2 hour maybe earlier. No oc at all all of them stock. After i saw this error miner don't start and rig crash. Thx in advance.

Anybody ?

I would say measure the output at the wall of the 390s using a kill-a-watt. The're cheep, every miner should have at least one. I don't have any 390s myself, yet(getting a 295x2 tonight) but they say they pull around 300 watts. If this is close to true you need another PSU to take the load. Keep in mind if your on the 120v North american standard your close 15 amps. Most households use 15 amps as the standard for each circuit.

If you want to try to change the core voltage or lower the clocks to save power, or take one of them out of the rig and see if it still crashes.

Thank you for tips. I will use my kill a watt tomorrow. I downgrade to 8.0 its looks good and no crash at all but when i last check in miner there are just 3 gpu's showing i need to work on it more i guess.

Same here but with Nvidia :-D.
So its nothing AMD exclusive.

maybe it's all about the algo, hashing it tends to use other parts of the gpu that's not that critical to playing games, watching videos, browsing etc.. maybe there's quite a few more room for extra hashes for both amd and nvidia out there.

I've heard that the world isn't just black or white :-D
but psssstt... maybe those guys also spread the word that the world isn't a disc and might be a globe.

[riser]

i'm amd use))) not nvidia

[KarinaKasimanova]

Thank you, it looks good.

Fantastic results Claymore . . . all versions have worked flawlessly on my three computers running five various GPUs! Many thanks for your great work!

There is no problem here except the one with your bold font!!!

Who knows the speed of 142 - 356 m / s to that effect?thenks

[QuintLeo]

9.1 going to be slow...nvidia card take over ZCASH...

there are maybe 1/10th as many nVidia cards in mining operation as AMD, and they cost roughly 2.5x as much to reach equivalent hash rate. It won't even be noticeable.

 More like 2x the cost for 1.7-1.8x the hashrate at the current development level of the competing ZEC miner programs.
 That's assuming GTX 1070s - I'm not sure what the hashrate out of 1060s looks like.

[QuintLeo]

I change server that 3333 to 3336 for 4 gpu but not change share found 358--257-390-400 ms

This miner is for me

https://dwarfpool.com/zec/address?wallet=t1YdKS8sstWxxdNs8Vz5TMtEAogSfAaXg4s

In now i used that server zec-eu1.dwarfpool.com:3336 ..my share foun change to 240-280-230 ms...thanks my friend...this better that 300 -400 ms

 Your issue is that Iran has very poor connectivity to most of the world - I doubt there is anything you can do to get consistantly low ping times on the shares your miner submits.
