Bitcoin Forum

Hey guys,

Just started mining today, and I'm using poclbm for my GPUs. I've got a HD 6990. I'm pretty sure this counts as two gpus, so I have two lines in my batch file. However, if I run the batch, and open up any other program, my computer will freeze and I have to manually reboot. If it runs by itself, it works fine. Is there anyway to solve this? I've also tried attaching the -f 60 at the end of both lines, but it doesn't help. I saw some other people talking adding other things in their batch files, but I'm not really sure what they were doing.

Any help is appreciated. Thanks.

Would be helpful if you could post lots more info about your setup your actual batch script etc. That could be lots of things :D

Also, what's your cooling situation like? A 6990 can produce as much heat or more as all the other components of your computer combined. You had better have some 120mm or many intake/exhaust fans.

Maybe an idea for a forum mod to setup a technical section to this forum and sticky a guide on how to post to ask for help with hardware errors etc ? 

Right now, I'm using

start /DC:\bitcoin\poclbm poclbm.exe --user=username --pass=pw --device=0 -v -w 256
start /DC:\bitcoin\poclbm poclbm.exe --user=username --pass=pw --device=1 -v -w 256

with my username and pw the same as the .conf file. And my cooling is fine, i've got at least 15 fans, (I game a whole lot.) It's just weird that the batch file runs fine and mines fine when I don't have stuff open. Is there maybe a way to throttle the gpu? And how do you know the gpu is mining for your address?

I just got a 5970 (dual gpu) having the same problem too
poclbm.exe --platform 1 -d0 --host=deepbit.net --port=8332 --user=xx@gmail.com --pass=xx -v -w 128
and -d1 too

I'm having a problem with it locking up my pc after a few minutes

Both the 6990 and 5970 guys seem to have failing or insufficient power supply problems.

IlbiStarz, TheShoura,

I have two possible reasons that come to mind.

The first is that you have buggy/old ATI Catalyst drivers. Updating those from the AMD website (http://support.amd.com/us/Pages/AMDSupportHub.aspx) (in the box at the right, select Desktop Graphics, Radeon HD Series, your graphics card, and operating system version) and try installing a newer version of the drivers.

The second is that your PC simply doesn't have enough power to sustain mining. It could be that your computer's power supply unit just can't handle the power draw. If this is the case, you might consider underclocking your GPU's memory clock (I am by no means an expert on this) to 300 MHz or so, which might reduce the power drain enough to leave your PC stable.

Hope this helps, good luck mining!

just got the card, just installed catalyst 11.4

i have a 1000 W corsair HX 1000 been using it for a while. rock solid

Same, 11.4 has been working for me, and I have a 850w 80+ Gold PSU. I game and benchmark, so I see no reason why the PSU or drivers would be the problem.

Any way to throttle the rate at which the gpu mines? Also should I do pooled mining or solo mining?

well i never tested the gpu really.... i just bought it and started mining on it... i have another gpu in my system (gtx 460) that i'm using for gaming only lol

Found the problem

I open GPUz while i had catalyst open on overdrive page and it crashes consistently

Try Phoenix with one or both instances not using BFI_INT. I've noticed since BFI_INT, I can't run two miners at once on my 6870 960/300 or 6850 800/300.

no point for me, that's slower

fastest was poclbm with some nice flags and I'm golden

the crash was most likely GPUz as I tried it again for a 5th time and right after opening GPUz I crashed

been running for half hour now while gaming no crashes at all.

I still crash when I open firefox though...

The 69xx series, maybe the whole 6000 series, has a problem with mining where anything trying to GPU accelerate something while mining will crash it. I had to disable hw acceleration in flash and in MPC to be able to mine, and just turn off my miners for some of my games (not all cause crashing, experiment).

I disabled hardware acceleration in Flash and MPC and set the core clock to stock when watching videos on the latter to avoid crashes.

Firefox can use hardware acceleration on it's own too, disable it from Firefox options.

How do you disable the flash and MPC thing?

I recently started getting crashes too but only when I try to stop a miner.

Hardware:
intel q6600
8gb ram
Win7x64
2 x 5770
650w psu

I'm using a GUI version. I'll have both miners running and everything's smooth enough then i'll watch video online and notice its not 100% smooth so I'll stop the miner running on that card and the system completely locks up.

This only started happening after I updated my drivers to 11.4. Before then I only rebooted my system monthly to do updates and I had my miners going around the clock. Now I'm stuck rebooting once or twice a day. Thinking of trying out the prerelease of the next driver or going back to previous version. Its weird it only happens when I try to stop the miner.

I had that problem too with my 5850.
I solved it by lowering the AGGRESSION level.

Yup 11.4 sucks :D I installed on a windows system and there was no end of crashes and I didn't even get to the mining stage. These drivers SUCK :D lol hopefully AMD is on the case because things like these really hurt there pockets I bet.
