750 KH/s steady and ONLY 1 FTC in 16 hours work ?
-
I have the same card but only 5GB of ram but I’m hashing at 846 Kh/s with WU 783/m: in 24 hours rejected shares is only at 9472 which is 37 rejects and errors is 0
Temp is steady at 80 with span speed at 70 %
This is my cgminer.conf file just stick in your pool and worker details and try it I’m getting about 22 coins per day
Don’t forget to delete the bin file before restarting.

I took a screengrab but pc crashed before I could save it.
anyway yes, plenty of errors on the H…
so the solution is? lowering the intensity?
and there was mention of clearing the bin file ?you do that when you use a new .conf ? -

[/quote]Correct, you delete the .bin file when you change the config.
If you use the config I posted above just copy and paste it into a new file called cgminer.conf and then just run cgminer directly without any shortcut parameters.
It takes a while to fine tune it I’ve been 2 weeks tweaking mine, I can get it hashing faster but it runs too hot and the noise of the fan at 100% is crazy loud, wife complained ;-)
How much ram have you got BTW? -
only 4GB.
I bought components to build a proper rig, hopefully this w-end, with a 7970 and 290, in there I will put 8GB Ram, is that enough?
I never heard before about deleting the .bin file.
I’m using cgwatcher by the way, so I point it out to the .conf, but if I were to use cgminer on its own is enough to name the file cgminer.conf and open it? not .bat ? -
i have no issues with 4GB mem, have it on all my rigs (each with 3x280X), and earlier they where 4x7970 each. No issue with ram beeing to small.

[/quote]I only had 4GB until last week and it worked fine, I might have been using a slightly lower thread concurrency though I cant remember for sure.
It’s fine to use cgminer on it’s own with the cgminer.conf file, I dont use a batch file at all, I just have a shortcut to cgminer.exe in my start up folder in case the rig reboots it will get back hashing automatically. -
thanks for the feedback. I’ll do some research on how to avoid Hardware errors, and as you all did spend a couple of weeks to find the best tweak. It sounds very straight forward the way with cgminer in start-up folder and cgminer.conf .
thank you again. -
This might be a bit redundant, but I found both my 280x had problems with hardware errors until I ran:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1So I’m posting that as a longshot.
In my impression you should have zero hardware errors and a reject rate well below 1%, but the latter depends on lots of variables in your choice of pool and chosen card config.

[/quote]Yeah, i keep forgetting those values, if you dont set em you are bound for high HW if thread-concurrency is set high:)

me again…such a newbie…sorry…
if I try with conf suggested above for example I get this error:
[img]http://imageshack.com/a/img854/524/z22h.png[/img]where do you insert this: in the .conf file right?
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1…ah found it… the .bat file… Iread about it somewhere but then forgot altogether…argh…
-
You can put it at the start of a .bat file like this:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -o (your mining pool) -u (your user id) -p x -g 2 -w 256,256,256,512 -I 13 --thread-concurrency 8192,8192,8192,10240 --lookup-gap 2 --gpu-engine 1055,1055,1055,1025 --gpu-memclock 1500 --gpu-powertune 20 --gpu-fan 30-100 --temp-target 70 --temp-overheat 90 --temp-cutoff 95Or run it once from a dos prompt…
-
if I use the .bat file that has all the info don’t need the .conf file anymore? I just run the .bat
ok got it.does this seem ok? I kept concurrency work and memlock and engine low…
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe -o stratum.wemineftc.com:4444 --scrypt -u xxxx1 -p xxx -I 15 -g 1 -w 256 --thread-concurrency 8192 --gpu-memclock 1050 --gpu-engine 855 --gpu-powertune 20 --gpu-fan 30-100 --temp-target 75 --temp-overheat 90 --temp-cutoff 95but with this result: see loads of errors again ?!?!?

That does seem a little low…
you might want to bump it up.
Most people have memclock at 1500, some at 1250…

What card do you have again?
-
Assuming you are on windows, I ran these once in start > run:
[table]
[tr]
[td]setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1[/td]
[/tr]
[/table]I’m a Linux guy, but used win for our miners as one is at a mates place - easier for him to learn. I think they are environment variables of some kind, so once they are set, they are set. In short I think you can leave them out of the batch file for your settings.
Also you should ditch any kind of tuning (by config or otherwise) until you can mine at all without errors! Start with a lower intensity and a basic config, such as:
cgminer.exe -o stratum.wemineftc.com:4444 --scrypt -u krasticrypto.1 -p xxx -I 15
-
R9 290 Asus.
Windows 7
That’s why I put the lowest config I could think of…just to start mining really! I wasted days already…
so the miner is running with that .bat file but HW is super high right?! :-\
Is it just a matter of tweaking? no major mistake that you can spot from the .bat? -
…and did you run those commands in run? ???
-
yes I did run them 1 line after the other in CMD and removed them from the .bat file.
also removed the .bin file. -
What drivers have you installed?
-
latest Catalyst I believe is 13.11
and also AMD-APP-SDK-v.2.9
