Hi guys.
I am having black screen problem with Gainward HD 4850 512MB DDR3 (first batch I guess, is bronze color heatpipe).
I am using Catalyst 8.10 (with Control Center installed). Set Fan Speed to Manual at 45%
Black screen happens while:
1. Update Vista Score, around Direct3D stages (it happens randomlly)
2. 3DMarks - Second stage (it happends while starting at the first few seconds)
3. Red Alert 3 - After playing for minutes, the screen will shake. Randomlly is becomes black screen
Please advice which driver or should I install control center, etc.
Hi there,
Yours card looks like one of those defective first batch. Please send it back to us for RMA. Courier it back to us. Click the company link below for our address and contact details. Just send the card back, wrap properly with anti-static bubble plastic in a tight box. Write down Gainward first batch RMA, and put ATTN: Mr. Steven Cheah.
Sorry for any inconvenience caused

, but please be assured that once you see the low temp of the latest batch (with nickel plated heatpipes and better chips), it will put a smile back to your face again. If you search the Net, you'll see that our card not only has low temp & super cooler, it's also highly overclockable.

Thank you for choosing Gainward.
