Ok man you need to stop checking cgminer settings, it's not a problem with the intensity or the cgminer variables, something is wrong in your system hardware wise if you are on a fresh installation with fresh drivers.

Hmmm...

Well, I did just uninstall a bunch of nvidia drivers (which was sketchy because windows kept trying to auto reinstall them no matter what I did) but I'm fairly certain I got rid of them (all nvidia files)  before taking out the card and replacing it with the radeon and installing the newest drivers. I don't think that has anything to do with it but thought I would mention it.

As far as hardware, I don't know what it could be besides the card itself.

88 degree is quite hot, and quite understandable that it crashes.
How is the airflow? is it in a closed cabin? if so try open the side window/panel and check the temp, if not try to lower the memclock down another 100

Yeah, I'd been keeping it at 85 or lower before.

I already have the side panel open. I'll try lowering the memclock more. I also have the fan operating at 100% for now.

Thanks.

Might as well try at a lower memclock and work us upward, try changing it to:
"
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+tcp://usa-1.liteguardian.com:3335 -u Sancho.1 -p x --intensity 13

--thread-concurrency 8192 --worksize 256 -d 0,1 -g 2 --gpu-memclock 1210

"

Thanks, but I actually already had it at memclock 1210. I should've mentioned that already.

I can't believe it crashed at intensity 12. Sad


DjNorad, I tried your settings as well (also with memclock at 1210) and it held up for a couple of minutes before it froze. Sad Thanks though. Maybe I'll try it at intensity 13 next.

I got good results with following parameters


start.bat
Quote
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+xyz.com:3334 -u user.1 -p x --expiry 5 --scan-time 5 --queue 0 --lookup-gap 2 --thread-concurrency 8000 -I 17 -g 1 -w 256

maybe this example could help you....

the red parameters reduced my amount of rejected files a lot....

I'm pretty intimidated about using intensity 17 when 13 isn't working. >_<
I'll try it though.

Are you running Linux or Windows?



F9, I've been trying to keep the temp around 85 if possible. I can't say how high it reaches at intensity 13 because it freezes soon after. EDIT: Although, it just crashed at intensity 12 around 88 degrees. Dammit!

What temp does the card reach?

Yeah, it's just the one GPU. I wanted to run another with it but it was nvidia and I thought it would be too risky.

My PSU is a Cooler Master Silent Pro M 850W Power Supply with Modular Cabling (RS850-AMBAJ3-US).

Yeah - using windows... hmm, I forgot about the OS - I will try it, thank you.

Edit: Was actually getting almost 1000 khash/s a minute ago before comp froze - with windows 7.


hmmm


Do you have big enought PSU ? Also this freezing happens to me when one of the power connectors going to GPU is burned.

My PSU is 850 watts - should be more than enough, right?

The power connectors should be okay, they are new. But I suppose it's a possibility.

Could the fact that I used two 6+2 pins from the PSU to the card instead of the two 8 pins that came with the card have anything to do with it? No, right?

Yes, for 1 GPU 850 watts should be enough.

I definitely got it used, ymer. Supposedly lightly.

I wonder if that's part of the problem? Maybe some settings are out of whack? Or maybe it's just fried? Hopefully the former.

I can get 450 khash/s now at intensity 11 and haven't frozen yet - but everything above that crashes me.

My hunch is that some asshole sold you a bad card, probably flashed with wrong settings, probably it overheats, probably has some power issue that makes it freeze...

This would sadden me greatly. Sad

Using the PSU dedicated 6+2 dedicated pins is better than using the card adapter, as long as you have all the power pins populated and your PSU is really 850W it should work just fine, what model PSU is it?

I had it holding steady at 1000 khash/s at intensity 12.

F9, I tried your suggestion and it still crashed. Sad Looked good for a second though at 1400. I was in the process of replying here to tell you it was working when it crashed. Sad

change the content of your batfile to include the following
"
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+tcp://usa-1.liteguardian.com:3335 -u Sancho.1 -p x --intensity 13

--thread-concurrency 8192 --worksize 256 -d 0,1 -g 2

One important question before troubleshooting, is your card new or did you buy it used?
