QUOTE(tech3910 @ Apr 4 2009, 06:29 PM) dis is b coz there bit different for the reference cooler. owh thanks for da info 4870 heatsink uses 2 8mm heat pipe, where 4890 uses 1 8mm & 2x6mm, total 3. in terms of fan speed, for the 4890 bios, ATI adjust it sightly higher den 4870, dats y it is cooler & noisier.  |

some nice info on HD4890 : http://forums.techpowerup.com/showthread.php?t=90117&page=2
1) Two users that bump their vgpu to 1.35(stock : 1.31) able to hit 1000Mhz core clock (im not sure either they have golden chip or not, but worth a try) 2) 1200Mhz memory speed (4800Mhz) is achievable with air cooling. they use VoltageFactory to bump the vgpu : http://www.awardfabrik.de/forum/showthread.php?t=5707 good luck to HD4890 user  |

Btw, I contacted the Sapphire Tech Support Center to ask them about the HD4890 driver and they replied to me saying that the driver will be available sometime this week.
