hmmm now im confused. sorry about the confirmation on logmein earlier. it happened again today twice. once after it happened, i turned it on again and windows was completeing updates, so that MIGHT be it, im not gonna confirm it though. sigh ill have to test the psu

Best of luck. Keep us posted.

hah! i can confirm it now! i just used logmein about 40 minutes ago when i woke up to see if it was still on, it indeed was then it shut off within the last half hour.

so people avoid logmein for rigs.

okay well guys its been running for over 10 hours now, im pretty confident it WAS indeed logmein.
i havened used logmein the whole tiem, and when i finally just did, i saw the mhash shoot down from 333mhash to 29mhash and then shoot back to 333mhash

i really hope this means my psu is not messed up.

thanks for your help guys, ill try team viewer maybe it wont crash it. but in anycase, logmein may be a suspect. if your gonna use it, use it for a couple of seconds just to check on it. im not gonna be able to test if logmein really does it because i got alotta stuff to do this weekend.

thanks again guys

From your second statement about the Mh/s crashing when using it, it sounds like logmein is accessing OpenCL and probably causing a conflict in the device driver. Why it would just poweroff instead of throwing up a BSOD is kind of odd.

you are probably right.
the thing is, it dosent entirely shut off, it kinda of just stops working, but the fans are still running, even though the operating system is now.

If you have another computer that you can test with if it happens again I would suggest the following:

ping to see if the system and networking are still up
try to connect to a file share to see if higher level networking is still online
try to do a remote desktop connection and see whether it's just the video card that is cutting out and killing the signal to the monitor as well

At least then you have some idea at what level it's actually happening.

That is highly odd. I googled your problem with logmein and no useful results came up. So this is something that you may wish to report to the logmein developers.

Good thing that your PSU wasn't at fault

Probably cheap parts. I have the exact same problem Sad

Well I dunno. I don't think the OP mentioned whether the power supply was new or whether the cards are new.

Therein lies the problem..in our drive to lower our costs us miners often run into problems that totally wipes out the savings we're chasing after.

No, I haven't had much luck figuring out how to lower mem speeds on linux. I think that's about the only thing left to get this computer running optimally.

I found that rail diagram when your initial post got me on the right track.

Hmm, there is a thread (or two perhaps) in the mining section which mentions a specific program you can use to lower the mem even under linux. I am pretty sure it's possible. It's really worth giving it your best because it can help you save some $ by lowering the power consumption of your card(s)

Yeah that diagram was very useful to me too a while back.

Single rail or multi rail power supply? If multi rail make sure you spread the load across all the available PCIE rails.

This post helped me tremendously. I have dual 6990s and an HX1000 power supply. The 6990s have an over-clock switch that raises the voltage and produces an extra 15% to my hash rates. It was causing the computer to freeze after a couple of minutes and I figured it might be overloading the power supply. Sure enough I didn't have the two cards spread evenly between the rails (in the case of the HX1000, it doesn't have rails but is kind of like 2 500 watt power supplies bundle together).

I have the same power supply and even with a single 5970 it is still recommended that one spreads the load across the two 12v rails. I'm amazed the PSU handled two 6990 on the same rail. However when I think of it I am not surprised as I've read somewhere that the HX1000W is conservatively rated (ie it can deliver more than 1000W if pushed) and it really a 1200W PSU sold as 1000W (designed by an OEM called CWT)

One of the cards was split between the rails, so one rail had 3 of the 4 PCIe cables plugged into it, and the other rail had 1. Even still, the power supply was pulling over 800 (I believe close to 900) watts from the socket.

Nice, you got yourself one serious space heater there

However I'd be concerned running the PSU at 80 to 90% rated capacity. I think that will shorten its lifespan.

Did you also try to underclock the memory on those cards? You can save 20-40 watts per card doing so.

Hey btw, checkout this picture to see how the rails are distributed on the HX1000W:

hmm well i had put in a fresh clean windows 7 with 11.4 cata and NO sdk, it seems fine but only for a couple of hours. im scared to logmein cus i dont wanna taint the testing. ill try out the psu on my other computer , but im afraid i dont have enough to overload it. i have 3 6990s but the third one wont fit into my computer case im gonna have to cut out a hole just for the third one.

thanks for your help though ill test the ram tomorrow and the cata if this problem persists. so far it has been running for an hour with no problem i only logmein once to start it up.

turns out i didnt need to use a dummy monitor with crossfire hope people make use outta this info.

I don't think you necessarily need to overload it. Even with those two 6990s you aren't overloading it. Just put as much strain on it as possible in a different system to see whether the fault lies with one of the components of the other system or with the PSU.

Btw, have you tried using something like VNC or RDP instead of logmein? I would be surprised of logmein caused all this.

by testing do you mean just plugging it in and running regular computer parts? I can do that, but is there any other solution? i spent a lotta time putting that power supply in heh Grin

That and also putting as much load on it as possible.

Also to ensure this is not a driver issue uninstall all the catalyst drivers, boot into safe mode and run driver cleaner (available for free on guru3d site or just google it) and remove all traces of the ATI drivers, boot back into windows and reinstall 11.4. If the problem persists then try downgrading to 11.3 (repeat the same procedure)

If even THAT does not work then something terribly wrong is going on. Check to make sure all the PCIE cables are solidly in place, and also do a memtest. Also keep an eye on your temps (for the 6990s) - possible overheat? Bad RAM would not cause the system to shutdown with no vide though (you'd get a blue screen) so I doubt it's the memory. So far I suspect either a faulty PSU or a catalyst driver issue.

+12V Rails
Single

thats the one.

i cant seem to stop it from being 100 percent cpu, i didnt put any flags (im using guiminer)

That is more than enough to power two 6990s, unless of course the PSU is faulty. Do you happen to have a spare computer you can test it on?
