Introduction

Sapphire Radeon HD 6990 4GB Video Card in AUSUM Mode 02 | TweakTown.com

You might've heard us mention this new "AUSUM" mode a bit in our recent Sapphire HD 6990 4GB. If you missed out reading our Sapphire HD 6990 Technical Preview, I'd highly recommend you check it out to see exactly what it does, even if you just jump to page 3 which covers "AUSUM" mode and the Dual BIOS switch.

Due to the fact we've already covered the Sapphire HD 6990 in quite a lot of detail, we'll just be getting straight into the specifications of the card when we flick that Dual BIOS switch to AUSUM mode.

If you can't be bothered reading the Technical Preview and you don't know exactly what AUSUM mode does, we'll quickly just cover how you switch it on and the clocks it carries when on along with any other features it brings. So with that all said and done, let's check out the GPU-Z information and exactly what we're dealing with.


AUSUM Mode

Enabling "AUSUM" mode is done by nothing more than a flick of the switch. Like the HD 6950 and HD 6970, we have that little switch behind the CrossFire connector(s) that switches between two different BIOS'.

The card ships with the switch in position 2 which carries the default 830MHz / 5000MHz QDR setup at 1.12v. Position 1 increases the core too 880MHz while also bumping the core voltage up to 1.175v.

To achieve this you simply just flick the switch over to position 1 when your machine is off. It's a little harder to do than the HD 6970 and HD 6950 as the shroud comes up and over the switch, making it near impossible to do with your finger. We just used a pen, though, and we were up and running at 880MHz / 5000MHz QDR in no time.

That's all there is to it. With a flick of a switch our core has been bumped up to 880MHz and what AMD is calling "AUSUM" mode is now enabled. What's AUSUM stand for? Antilles Unlocking Switch for Uber Mode.
