Hi there,

Need some helps. Tryed Google for several hours but havnt found a good answer.

One 5830 of mine gets "Connection" problems frequently. When i press start and stop, it will work again for several hours. How can i fix this? Is there a logfile somewhere?

Thankyou verymuch.

One of my sapphire 5830's does this, the reason being too low fan speed. Core stays at a stable 55-60c but the VRMs are overheating due to a lack of airflow to them (fan speed is about 35%). It crashes when the VRM gets too hot.

Also, even relatively low overclocks or voltage increases can cause these cards to crash after a few hours.

Crappy design but you get what you pay for....

Try decreasing in 5-10mhz increments and see when it eventually gets stable 24/7. Or if you just want to 'play it safe' try about 880mhz right away, it shouldn't be crashing if you can already push to 900 and run it for hours.

Even if the chip and VRM are stable, it could just be a bad card which doesn't OC well

I have the same problem, but I know it isn't because my VRM's are getting to hot (because I have them water cooled, and they never break 55C).
