QUOTE(blindbox @ Apr 15 2009, 10:52 AM) @jinaun: Wouldn't a better setup be 4870x2 on top? good idea.. as you can see.. the setup is pretty tight.. the 4890 was grasping for breath...usual idle temp of ~58C climbs upto 65C++.. i think i'll put the 4890 at the 3rd pcie slot(bottom) and the X2 at the first slot (top) so there is more space for vent This post has been edited by jinaun: Apr 15 2009, 10:46 PM |

QUOTE(metsatsu @ Apr 15 2009, 10:37 PM) but hey bro, hope everythng goes well for u. maybe one day u can offer custom made cooler skin in the future and sell in garage sales Not that desperate for cash, will never be that desperate for cash   I'd do it non-profit, but the design's not the hard work (making it fit on to the sticker is) |

Guys, Asus 4890 provided this SmartDoctor voltage tweak program.
After tweaking the voltage, do you guys usually leave that voltage tweak as long as your computer is on, or just for gaming? |
