Ive noticed a button on my 280, it glows blue when i press it and has the Sapphire logo on it, anyone know what it does ?

Like many of Sapphire’s video cards, the Dual-X R9 280 has a dual BIOS, one is used to boot in legacy compatibility mode, while the second boots with UEFI. All that it takes to switch between the two is a push of a button along the top edge of the video card. The dual CrossFireX connectors can be seen on the PCB behind the button

1) Pre-OS and network security: Sapphire HD 7730/UEFI ready products equip the UEFI firmware that is digitally signed and approved by Microsoft for Secure Boot. With Windows 8’s secured boot architecture and its establishment of a root of trust, the customer is protected from malicious code executing in the boot path by ensuring that only signed, certified “known good” code and boot loaders can execute before the operating system itself loads.

2) Faster boot and resume times: When compared to the legacy BIOS, systems with UEFI has a much faster boot and resume time to the OS.

So the legacy one is no led, and glowing led is UEFI no ?

What if i have a regular non uefi bios on the motherboard, does it matter ?

Ok, leaving aside the glowy button for a moment, i dabbled into some overclocking on this card and i set the power limit to 20%, and did Unigine Valey runs while raising the core .

I got to 1100, at 1140 it crashed the app. I played some games for about 1 hours, did a couple of more valley runs and it seems fine, valley gave me a 200 point boost.

But im concerned about doing damage to the card, always that nagging feeling that im pushing it.

Should i leave it like this ? Temps seem fine btw, never reaches 70 celsius but i can't see the VRM temps in GPUZ
