4870 ASUS TOP BIOS (upto 900MHz in CCC)

[xMrBunglex]

for those who haven't seen it yet: the Accelero Twin Turbo.

CrossFire compatible, comes with VRM and memory heatsinks, and even a 4-pin fan connector so you can plug the fans directly into your video card's PCB and control fanspeed through your video BIOS or CCC profiles. i'm excited. heat is definitely an issue when you have two 4870's sandwiched together like i do.

Korrupted, maybe you and i are in the same boat. i'm not game stable over 800 core with this TOP BIOS. maybe i'll mod my original BIOS and see if the same clocks work for me.

I think we could be; it took a full uninstall and reinstall of driver twice before I was back to normal, after I re-flashed back to the original. Running fine at previous speeds of 790/1100 again.

I added a 3rd stick of DDR to my rig yesterday prior to having issues, but they didn't crop up immediately, and I've had this same DIMM in my rig previously, with no problems. I did end up moving the slot it was in, just for the heck of it, after I had re-flashed back to original. Doubtful it was related, but it's a possibility. I'll test again at some point but I didn't like not being able to game yesterday.

I noticed that if you flash a new BIOS, edit the fan speeds in the BIOS you are using, or edit the fan speeds in the profile manager, you should run AMDgpuTool to reset the card and drivers, I described how to do this earlier on in this thread.

Seems that the drivers remember certain settings even after a BIOS change and/or reboot and above method is only way I figured out how to reset them without having to wipe the driver and reinstall it.

Well after a little GPU vmod a 32ohm resistor yielded 1.34 volts (looks nice and clean) and this ASUS BIOS I am stable at 825 core, tested with ATItools artifact free for over one hour.

Although the fan profile in this BIOS was good I edited the BIOS to fan speeds more to my liking, with vmod GPU idle's at 46c with 40% fan speed, and peaks at 64c with 50% fan speed.
