Just wanted to relay my recent experiences with my 5970s. I recently acquired two of the Sapphire 5970 OC Editions, which installed without issue. However, very noticable issues were noticed, the first being a screen flickering issue (which is an issue with ATI PowerPlay). The second was a complete absence of temperature indication in CCC, and a total lack of fan speed indication or control.
I did some research and discovered that a BIOS flash from Sapphire was required to resolve this issue. I grumbled, especially considering that to have bugs like this on a newly launched premium product is annoying and disheartening. But, I flashed them anyway (one at a time) as the flash program is incapable of doing both at once. Then, when trying to reboot with them, found that they were bricked. Some additional research enlightened me...apparently the support file from Sapphire had the two BIOS files (one for each core) mixed up in the batch file and only by manually reversing the two in the batch file and reflashing was I able to recover the two cards (again one at a time). If I didn't have a bunch of spare video cards to boot the system to reflash, I'd have been hooped.
What kind of sorry excuse for a launch is this? Three hours of my time to flash brand new cards (with the new BIOS 10 days newer than the old) and then recover my cards from Sapphire's own batch file screwup (which is inexcusable IMO). Did Sapphire (one of ATI's closest partners) not do any quality control on these cards to check for issues such as these? Beta drivers at launch is bad enough, but this is ridiculous. Especially on a premium flagship product who's availability is only slightly better than that of vaporware.
I may have complained if the cards were announced but not available, but I'd have preferred that to these buggy drivers and immature BIOS. This is not a polished product, nor is it ready for launch to the general public. But it seems ATI is so desperate to press the advantage against NVidia and get the cards launched in some sort of availability for Christmas that they've lost sight on the value in having a polished, high quality product.
Unfortunate, to say the least....:(
