problem reaper/litecoin/7970

[sshiva1172]

hello,
I am a beginner,
I try to use reaper v13b4 64bits this week, to mine with my sapphire oc 7970 in litecoin.
I'm using windows 7 64bits (q6600 quad core, 4gb ram, motherboard asus p5q).
Reaper seems to be unstable with my configuration. The 2 last night my computer reboot the first and crash the second night (black screen)... Don't know why...
My litecoin.conf looks like:

worksize 256
aggression 16
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 24576


My actual speed is 489.8kH/s
but when I put agression 20 it run faster (perhaps over 700kH/s, don't remember)
Am I using the good parameters?

I   really want to stabilize my mining rig...

Does CGMiner a better solution for my 7970?

Sorry for my bad english and thanks a lot for the explanations.

It's worth trying cgminer, with decent parameters you should hit +600khash with that.

What kind of PSU do you have on the computer?
Have you overclocked the 7970 yourself?

hello BBQKorv 
my psu is lepa g1600.
The graphic card is a SAPPHIRE HD7970 3Go Dual-X OC Edition (11197-03-40G).
I have not overclocked anything...

Is there any software which abble to see the hardware consomation, temperature?

[BBQKorv]

This might be the best way to check all the sensors your computer has: http://www.hwinfo.com/

Your PSU seems to be in order 

I would recommend trying cgminer just to be sure. I'm not so used to reaper but maybe you should try 2 threads per gpu. That 490kh is low.

If your temps allow you could try to overclock the gpu to 1100/1600. Memory should be as high as possible, but that needs plenty of testing to find highest stable value. I have found furmark+unigine heaven or valley to be a good stability indicator, 30 minutes of those two running together will tell if your OC is ok.

Hello,
Yesterday I have installed Ubuntu to test the hardware with another system...
I tried to mine with the bitminter client, run fine for 2 hours until Ubuntu was running bad (the windows where clipping) but no crash, this was not the psu the culprit...
What can I conclued? The card seems to be ok when I used it for a desktop usage...

This morning I open Catalyst Control Center and set the fan speed control from automatic to manual and increase it to 60%. I have never heard the fans so hardly...
Now it works since this morning and don't crash...
That's a point I didn't matter because I thought the catalyst driver was adapting the fan speed according to gpu temperatures but this is not an obvious fact.
Can you explain it to me? And do you regule yourself the fan speed? What percentage?

[sshiva1172]

Now it run since 24h, maybe the fan speed was the solution...
What fan speed do you use with your 7970 card for mining?

[BBQKorv]

I use MSI Afterburner to over/underclock and to modify the fan curve to my liking. Fan speedcurve is set so it keeps the cards at <80C. Having multiple cards in one system means the topcard will have like 85% speed while the lowest one has only 55% or so.

My rig just have rebooted, mining since 36h...

The problem bound to the heat and I settled(adjusted) the fan to 65 %.
Since I had no crash...

But since yesterday reaper post(show): error stratum.

I am on Coinotron and I saw that he(it) had passed in the stratum and I getwork connected me there there.

I have downloaded stratum proxy, and the fork of reaper.

I run stratum proxy with: mining_proxy.exe -o coinotron.com -p 3334
(this what is explain on their web site)

And when I double click on reaper.exe, it open a console window compil a "reaperv13.Tahiti-256-24576-2.bin" and then shut down the window instead of starting mining.


Before, with the official version of reaper it was compiling a "litecoin-reaperv13.Tahiti-256-24576-2.bin"


my reaper.conf is:

kernel reaper.cl
save_binaries yes
enable_graceful_shutdown yes
long_polling yes
platform 0
device 0

mine litecoin

and my litecoin.conf is:

host 127.0.0.1
port 3334
user xxxxxxx
pass xxxxxxx

protocol litecoin

worksize 256
aggression 17
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 24576

Try using cgminer with an intensity of 13, a core clock of 1022, and a memory clock of 1244.

Sorry, but I don't manage to compil it...
I read the windows-built.txt, but I think I have to skip a step somewhere because when I tape in minGW shell:
$ adl.sh
sh: adl.sh : command not found
$ autoreconf -fvi
autoreconf-2.68: 'configure.ac' or 'configure.in' is required...

which is Gibberish for me...
