Extending Overclock Cap (MSI AFTERBURNER)

post #1 of 10
Thread Starter 
I've maxed out my HD6970 at 950/1450. Temps are maxing at 75*C after 5 minutes in furmark. I'll run it again overnight.

How do I increase my overclocking slider? It's maxed out... frown.gif

DO you needs voltage too? Is that a typo, 1gb? Do you have a backplate on your card? If so while visiting that site check up on rbe.

If not:

It depends, if he's got a real true reference 6970 or not. Some later ones got volt controlled jacked from the card. If he has a true rev1 ref card, its clear skies, rbe + racerx = the win.

I am at stock volts. That IS a typo, it's the 2GB version. I don't have a backplate. I'll check that out, thanks!

Cayman, true reference Cayman was the bomb. It's got almost non-existent OCP on with excellent vrms by Volterra.

I'm 90% sure you can flash the bios. Thus I would make a copy of your #1 bios and edit the voltage to what you want, if you want any. Then uninstall AB choose no when it asks to save. Run racerx from Baggz, unlock overdrive to whatever you want. Reboot, run AB install but this time only use AB for fan control and OSD monitoring. The RBE+racerx method is the ideal way to overclock on Cayman.

Backplate = Volterra digital vrm, aka true reference pcb. No backplate is revised reference with chil controller. Some of these revised boards got their flashing and volt control removed.

After looking into it a bit, I'll stay where I am until I get better ambient temps. 23*C is too hot.
