Personally i have no issue with the dev fee. This guy/gal claymore clearly knows how to code these miners, make them better and puts time in developing a working product.
So what if there is a cut to use the program, isn't there with everything in life? You are going to pay one way or the other, and people who render services ought to get something out of it.
Thank you claymore, keep doing what you do. You are a valuable asset to the community.

if you have ever looked at how much claymore makes off all of us, its way more than something lol, more than enough to make most people feel as if there being robbed, and that's just with one of his miners. I mean if yall want to talk about someone who thinks there self entitled well tahts the kinda dev that puts a fee in that we cant do shit about, while offering the same program devfee free for extremely large amount of money to which no one but a farm could even remotely afford,anyone has a valid point to bitch and complain about a devfee, claymore has made more than enough to reduce the fee, but yet he doesn't, does that make him look greedy yes absolutely, but its not going to change anything. also on a side note we the miners are more of a valuable asset to him than he is to us. anyone that can already code could take the time to learn to make a good miner to put him to shame that has a reduced fee

Then there is the fault in this viewpoint. Its the common "despise the rich/capitalist man" type of ideology.
What is it to us if someone makes good money one may ask, what does this show us and in what ways can we response to that?
Now some of you will respond to that and say, oh well this or that has taken advantage of the little man, its greed and in the process envy and sometimes emotional hate filled myopic viewpoints devour you.
Or some of you like me can say oh well hey thats the dream right there, success, proof you can get ahead and in that state of mind just be really happy for those who are successful. Nothing is truly free, nor should we have expectations of such. You can let it drive you and your ambitions or let it devour you with envy. So that is really all the "hate the rich" mentality amounts to as we cant really control or be a absolute of anyones level of success or measuring stick of even what you see success as right?
But hey free speech so bitch on if its really gonna make things better for whoever has a issue with it. 

However i do agree that a consumer of any good, be it miners for claymore or potatoes buyers for the farmer the consumer is always the most important asset.
With that said, claymore could just as easily package his miners for botnets in torrents or something and really screw a good lot of us over. Instead he/she goes public with solid programs
and offers them for a small fee per user that in a sense really does exponentially cut into what he/she could be making using these programs in a nefarious sense.
I believe claymores public consumer offer is fair and honest so i value that and appreciate the opportunity to use something i wouldn't otherwise be able to make myself.

Hey guys, just pulled some old cards off the shelf to start mining again (280x and a 7970). Mined plenty of coins in the past but never ZEC and am running into some issues...

Setup:
Mobo - Asus M5A78L-M LX PLUS
OS - Win7 64
PSU - EVGA 700w Bronze
Miner Version: 12.0, 12.4
Driver: 15.12

The 280x (Sapphire DualX) is detected and hashing at around 240 using 12.4 and 180 using 12.0, but the average seems to be around 290 so I'm wondering how to increase these speeds a bit. Stock clock speeds and BIOS. Also, the 7970 (IceQ) is not being detected at all. Tried reinstalling the drivers and switching PCI-E ports and risers, still no luck. Virtual memory is set at 16gb. I've never had to use the "jumper trick" on this motherboard, but I was also mining on Linux previously - would that make a difference?

Running at intensity 5, are there any other config settings I can change that would help? Any assistance is greatly appreciated!

EDIT: I'm a dummy, the USB port on the riser wasn't plugged in all the way and the 7970 is working now. The hash rate increased a bit with the second card in (250 H/s per card) but is still about 40 H/s slower than other people with stock clock/BIOS settings.

Also, what utilities are people using to undervolt these older cards? Is it a desktop app, the BIOS, or can this only be done by reflashing the card itself? Thanks again!

I find MSI Afterburner works well for undervolting and changing clock speeds.

Problems of this version with yje update of windows.
I have 3 sapphire r9 290x and with the updates send by microsoft this days of windows 10 to version 1703 i saw that it also it automaticaly updates my drivers to 17.1.1.
I began to have problems of falling.
Has someone the same problems??

 You have just run into one of the 2 biggest issues with Windows 10 - it's insistance on  (and the VERY HUGE pain of trying to get it to NOT) automatically updating things that BREAK software.

 Earlier versions of Windows had the SAME, FREQUENTLY AND OFTEN COMPLAINED ABOUT "feature" but earlier versions made it fairly easy to turn the autoupdate bug OFF - Windows 10 makes it a royal PITA, especially if you do NOT have PRO or "higher" varients.

 AMD also has an issue that ALL of their "relive" driver versions are junk bloatware to date, don't work well even on NEWER cards like the RX 470 and are absolute GARBAGE if you have R9/R7 or older series cards.

 These sort of issues are why I specifically recommend that dedicated mining machines should run LINUX - once you get a LINUX box up and running, it doesn't BREAK things for you and tends to STAY up a lot more of the time than Windows is capable of doing.



 To jddebug:

 For my Gigabyte Windforce R9 280x cards, I find that core clock 1100 and memory clock at 1250 seems to give optimal results (anything over 1250 mem clock seems to introduce too much latency, anything over 1100 core and they start crashing) - stock BIOS running 12.4 on XUbuntu LINIX gives me right at 300 sol/s per card (one a tick over, one a tick under) *IF* I can keep them cool enough - the heat wave we had last week had them into thermal limiting a few hours a day, due to the limited ventilation options on my current place.
 Your cards may vary, I've seen folks claiming to be able to clock R9 280x as high as 1200, but I don't know if they had "factory stock" cooling on them to achieve that, or perhaps just better luck in the ASIC quality lottery (mine are both mid-grade).

 I doubt anyone you're seeing in the 290 sol/s range are running stock clocks AND stock BIOS.

 My cards are not undervolted - and in the testing I've done on them they seem to be locked on voltage in the BIOS, as they just shrugged off my efforts to undervolt them when I had them in a Windows machine with Afterburner, so seems like BIOS mod or flash with a UV-specific BIOS are the only options (this makes sense, as my R9 290 cards were DEFINITELY voltage-locked in the BIOS and I had to flash them with a BIOS from TheStilt to get them to undervolt).







I'm no longer legendary just in my own mind!

Thanks for the specification! I'll play with the clock speeds a bit, bummer that the voltage is locked. I used to mine on Linux exclusively and decided to give Windows a try this time, may have to test both. Advice was much appreciated.

@ toti

I had the same problem but found a solution.

search for:
1. "disable windows driver update"
2. "disable windows driver update group policy" (if you have win 10 pro)
3. "windows tool to show hide windows updates"

then:
4. deinstall all amd drivers by amd tool
5. install the drivers that you want to have AND deselect during this installation the auto update function of AMD installer

You have to do all points above and after that windows probably update your drivers.. then

6. roll back to older drivers. to do this windows will ask why you dont want new drivers. select one out of a list given to you and NOW its done Wink

I have three r9 280x cards. I use ubuntu server 14.04 and installed the amd catalyst driver using this guide as reference:
http://spacience.blogspot.com.tr/2015/11/gpu-mining-in-ethereum-1404-from-scratch.html


I installed atitweak to set the clock speeds and needed to install a minimal X11 to set the clocks and to see the temperatures.
I put a script in cron run at boot to start xinit in a screen and set the clocks and start the miner in a screen too. it works very stable.

My rig has only 5GB RAM and 5GB swap space.

Can i mine Zcash with a ATI 6850?

From page 1 of this thread:
This version is for recent AMD videocards only: 7xxx, 2xx, 3xx and 4xx, 1GB or more.

So no. I think you can use his XMR miner with older 6XXX cards so instead of scrapping it you can use it for something.

XMR, yes, but 1GB is too low, just an example HD 5870 1Gb gives 200h/s, same with 2Gb gives 300h/s, sell it while you still can recoup something...

Thanks for the tips - used to mine on Ubuntu 14.04 (back when DarkCoin/DASH was still competitive with a GPU) with the Catalyst drivers and semi-automated with cron jobs and BASH scripts. If Win7 proves unstable I'll gladly spend an afternoon switching back to Linux. Aside from the girlfriend's gaming computer, the miner is actually the only Windows machine in the house (typing this on my laptop running Ubuntu MATE Cheesy )

What clock speeds did you end up settling in on with your 280x's? Did you just adjust core clock speed or did you play around with memory clocks as well? I've got -mclock at 1500 and -cclock at 1150 and things seem stable, wondering if you can push these cards to 1200 without too many rejects.

Hello again. Smiley

Here is my .sh script to set the gpu clocks: The first GPU is r9 270 and the others are r9 280x.

miner@rig1:~$ cat set.sh
echo "setting clocks and fan speeds..."
atitweak --adapter=0 --set-engine-clock=950 --set-memory-clock=1400 -p "-20" --performance-level=all --set-fan-speed=100
atitweak --adapter=1 --set-engine-clock=1050 --set-memory-clock=1500 -p "-20" --performance-level=all --set-fan-speed=100
atitweak --adapter=2 --set-engine-clock=1050 --set-memory-clock=1500 -p "-20" --performance-level=all --set-fan-speed=100
atitweak --adapter=3 --set-engine-clock=1050 --set-memory-clock=1500 -p "-20" --performance-level=all --set-fan-speed=100


This script is run at boot after calling xinit. And miner starts 5 seconds after that script.
I set the fan speeds to 100% and let the claymore miner manage the fans too. after miner starts, the fans are running about 50% with about 65C temperature.

I played with the clock. if I put more that 1500 for mem clock, hashrate drops. below 1500 hashrate drops too, so I found it's optimal to set them at 1500.
1050GPU is good too. I can make it 1100GPU clock but hashrate increases just a little bit but power usage and heat rises so 1050 is good for me.

here is the output of atitweak -s command:
tim@rig1:~$ atitweak -s

GPU 0 is Asus r9 270. stock bios.
GPU 1 is Asus r9280x DC2T. modified bios to lover voltage a little bit.
GPU 2 and GPU3 are Powercolor Turboduo r9 280x cards.bios modified for lower voltage.

I used VBE7 in windows to make bios modifications and used atiflash in a dos bootable flashdisk to reflash the cards.

I have a power meter on the plug and it shows 750watt total system running claymore zcash miner.

The r9 270 makes about 170 hashes and r9 280x cards makes about 290 ~ 300 hashes.

Derp, thanks! I've tried a few different ones but none have really netted any increases in hashrate. They all flashed just fine, though!

Hello again. Smiley

Here is my .sh script to set the gpu clocks: The first GPU is r9 270 and the others are r9 280x.
Wow, those are some impressive numbers, thanks for sharing. I'm running a HIS 7970 IceQ (Hynix), a Sapphire 280x DualX (Elpida), and a PowerColor 7950 (Elpida) and have scoured the boards for a ZEC-optimized BIOS for each but have been utterly unsuccessful. Will keep trying, though!

thats true but i could find every bios name i needed in the google docs and then dl it from google drive Wink
Derp, thanks! I've tried a few different ones but none have really netted any increases in hashrate. They all flashed just fine, though!

Hello again. Smiley

Here is my .sh script to set the gpu clocks: The first GPU is r9 270 and the others are r9 280x.
Wow, those are some impressive numbers, thanks for sharing. I'm running a HIS 7970 IceQ (Hynix), a Sapphire 280x DualX (Elpida), and a PowerColor 7950 (Elpida) and have scoured the boards for a ZEC-optimized BIOS for each but have been utterly unsuccessful. Will keep trying, though!

For the ZEC mining, you do not need the special bios for 7970. There is very little difference.

claynore the v12.5 has some issues with auto fans speed on MSI AB 4.3 with Sapphire R9 290 TriFan,using win8.1 64bit Catalyst16.8.2, the fan speed goes from 70% to 40% while mining, so I wonder if you could do anything for this?

Not massive differences no, but some. There's a whole thread dedicated to ZEC BIOSes for Tahiti cards with modified memory straps which give better speeds: https://bitcointalk.org/index.php?topic=1676474.0

Unless there's a way to hit ~290 H/s without a BIOS mod? 290-310 looks to be about the max for the 7970/280x cards.

Are the fan issues present in v12.4? Don't think 12.5 gave any noticeable increase in speed so if it fixes the fan issue I'd use it instead. Moreover, I've always heard that Catalyst 15.12 is best for the R9 series when mining ZEC, have you tried using them instead?
