750 KH/s steady and ONLY 1 FTC in 16 hours work ?

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 -
Well you shouldn’t be getting those hardware errors with those tame settings, you should just be getting a low hash rate.
Have you uninstalled and reinstalled your drivers?
-
aaaaaaaaaaah 0 errors now!
with intensity 11 and concurrency 16384
ok I’m getting somewhere!
at least there isn’t anything totally wrong with the set-up. that’s all I want. would you mind double check it looks fine? I’ll work on getting higher KH/s slowly tweaking…

You normally set your thread concurrency, then memclock, then engine…
Clear all the bin files out of your CGMiner directory and run it without a thread concurrency setting, it will then give you a good starting TC in the first bin file it creates…
-
ok I’m getting 774KH/s now with these and no error
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe -o stratum.wemineftc.com:4444 --scrypt -u krasticrypto.1 -p xxx -I 20 -g 1 -w 256 --thread-concurrency 24576 --gpu-memclock 1250 --gpu-engine 855 --gpu-powertune 20 --gpu-fan 70 --temp-target 75 --temp-overheat 90 --temp-cutoff 95not sure what fixed it but I guess running in command those 2 lines? and fine tweaking? mmm…
I’ll post the config somewhere if I obtain better results.THANK YOU SUO MUCH EVERYONE!!!

Nice work dude.
Now edit the password from your post above and change it at the mining pool. lol 8)
-
Grab the model number of your card, then take a look here https://litecoin.info/Mining_hardware_comparison
You’ll get your next set of gains from tweaking Thread Concurrency, GPU Memclock and GPU Engine.
If you hit G then C you can play with memclock and engine on the fly within CG Miner.
You want to find the optimal ratio between memclock and engine, normally around the .57-.6 mark.
Enjoy, this is the fun part ;p

changed the passwords…thanks for the tip…ufff…
and yes now that is a matter of tweaking I’ll enjoy it…now that I lost half of my hair over HW errors and crashes…
gosh what a newbie…ahah
thanks so much!
