We are walking in complete darkness. We don't even know what causes the throttle. I say it is temps. It cannot be power. It's always 870mV under heavy load and if the temps do not exceed 80*C the cards are not throttled.
Identify the cause first and then start your modifications. Furmark is no good. 5*0m line and the drivers are made so to downclock while a user is running particular applications like Furmark for example.
Barcode, make sure you properly identify when the throttle kicks in. Heat up the cards up to 80*C and see what happens. Do not run 3Dmarks. Run some demanding game (e.g. crysis 2) and force the GPU fans to spin slowly using hwinfo. You should be able to reach 80*C easily enough.
