If your card is Sapphire 9800 NP with Samsung 3.3 ns memory, you can definitely flash the card with Pro bios and hit pro speeds. My Sapphire with Samsung memory wouldn't overclock to Pro level either until I flashed it. Pretty much every 9800 NP w/ Samsung memory hit Pro speed or higher when flashed. Now if you have Infineon memory you're out of luck. Those don't overclock worth anything and are dangerous to flash.
If you have Samsung memory feel free to flash to Pro bios.
Thanks, I appreciate the testimonial. However, if it won't hit "speed XYZ" when overclocked, there's no reason to assume it'll hit "speed XYz" w/a new bios. 🙁 I don't want to fry my card. In fact, I've read to test your card by overclocking first to see if your card can hit the speeds. If you can't hit them, flashing isn't a good idea.
Almost all 9800 NP will NOT hit Pro memory speed before the bios flash. The bios flash gives more volt (maybe) and relaxes the memory timing (definitely) so that the memory will hit Pro speed. Trust me you won't fry your card. As long as you flash it with proper bios and flash software you will not have any problem with that Samsung memory. If you decide you don't like the Pro bios you can always flash it back to NP bios.
I sold my flashed 9800 while back. I now have 5900 NU. I flashed this card with 5950U bios. This card didn't hit Ultra level before the flash either. I would get severe artifacts when overclocked not even close to Ultra level. After the flash, no more artifacts and I can overclock even way past Ultra level.
Would you happen to have any links to the proper BIOS and flash utility?
