Topic: Litecoin mining with R9 280X, too much HW (Read 1634 times)
No need to add the -shaders 2048 as the thread concurrency setting does the job. I would also add -gpu-fan 100 to keep the temps as low as possible.
Thanks everyone for your replies.
I finally found a solution. The msi card are working well with:
cgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:8080 -u x.x -p 1 -I 13 -g 2 -w 256 --thread-concurrency 8192 --shaders 2048
But I still get high temperature, maybe because they are too close from each other, I'm not using risers.
I'll try to figure out how to fix this, thanks a lot.

are you running open case with risers?
Try this:
setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:8080 -u x.x -p 2 -I 13 -g 2 --thread-concurrency 8192 -gpu-fan 100 -w 256
If that start up ok then overclock your card core and especially the mem. Something like 1050/1700 using the --gpu-engine and --gpu-memclock flags
Once you get your highest clocks set you can also try to raise the thread concurrency to 11200
Alternatively you could try this:
setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:8080 -u x.x -p 2 -I 20 -g 1 --thread-concurrency 22400 -gpu-fan 100 -w 256
Same applies about the overclocking, try to find your highest stable memory clocks.
setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:8080 -u x.x -p 2 -I 13 -g 2 --thread-concurrency 8192 -gpu-fan 100 -w 256

check the settings, seems something wrong.
You are missing critical settings such as the gpu-thread, thread-concurrency, and -worksize flags.
Try this config:
Try this config:
Code:
setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o ?? -u ??? -p ??? --no-submit-stale --thread-concurrency 16384 --intensity 13 --worksize 256 -g 2 --gpu-engine 1050 --gpu-memclock 1500 --gpu-fan 90

lol, now it's at 100°... I hope that won't burn the room where I installed them lol
Don't let the temp go over 85.
if they're like most radeon cards, they'll throttle themselves down at 100oC
which means, you shouldnt be near 100oC

I think the HW is cuz of the temp. Try lowering voltage to make it run cooler

Holy fucking hell that is WAY TOO HOT.
Hello,
Could someone help me?
I just got my new graphic cards and launched cgminer 3.7.2 with the folowing settings:
cgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:8080 -u x.x -p 1 -I 13
My configuration is as follow:
Operating System Microsoft Windows 8 Professional 6.2.9200.16581
CPU Type OctalCore AMD FX-8350
Motherboard Name MSI 990FXA-GD65 (MS-7640)
DIMM1: G Skill F3-12800CL9-4GBXL 4 GB DDR3-1600 DDR3 SDRAM
Video Adapter AMD Radeon R9 200 Series (There is 2 cards not used in crossfire:
The cards are: MSI Radeon R9 280X TwinFrozr 3G and Gigabyte GV-R928XOC-3GD
But when I launch them I get a hudge amount of HW as shown below:
http://img28.imageshack.us/img28/8441/oh3s.png
I also tried to run it on Arch linux, I still get the same errors...
I have another computer with the exact same configuration excepted that it have 2 msi card instead of 1 msi and 1 gigabyte.
Does someone know why I get these errors on both of my computers? Please help, all my 4 card are giving me the same results.
Thank you.
