6870 cf oc

post #1 of 5
Thread Starter 
Hello everyone. I recently received two HIS 6870s which are now in CF in my sig rig. However, trying to OC them, I seem to hit a wall at 955/1100. I've seen a lot of people getting 1000 core in CF which is what I am striving for. I am using 10.12 drivers, and MSI AB which I cannot get to see the voltages. Any help would be greatly appreciated.

I didn't ask for your snide comments, so please troll somewhere else. I've had just as many parts fry on high-end PSUs as low-end (used to have 2 9800GX2s on this same PSU before my kid sister spilt soda on my case and killed the cards). And if you're so concerned that you have to troll my thread about it, give me the money to buy a new one because honestly I don't have it.

Anyways, anyone got any ideas? Should I revert to 10.10e since AB seems to support it more?

Well this may have no relation with crossfire but for my current OC 1000/1250 required 1.3v and also, its 100% stable on drivers 10.11e but for some reason, 10.12 did not agree with my overclock so I rolled back to 11e. Hope that helps.

Alright, thanks, also, what fan speeds are you running when at 1.3v? I have mine set to 45% at stock and the cards don't go over 65c.
