How to safely use Afterburner voltage adjustment.

[Grizzly]

Hello once again.

Package arrived this afternoon. Containing a 580 Lightning.

The Lightning is the first card I've had that supports voltage adjustment and was wondering how I should be using the voltage adjustment, can I set each slider (Core, Memory, Aux) to max and not have to worry about frying my new 580 or are there limits I can surpass in Afterburner that I shouldn't?

Thanks in advance.

Nice card

The limits you can see in afterburner are set by msi in the BIOS so you can Max the sliders out and as you have enough airflow to keep the card cool you should be ok.

You might find after a bit of testing that you don't need to Max out the slider for the Max speed you can keep stable anyway as temps will be the limiting factor.

Thanks for the reply, exactly what I was hoping for.

One other thing I didn't really think to ask is what is Aux voltage adjustment for, core and memory are easy enough to guess.

Version 2.0.0

- Voltage control layer has been seriously revamped to give additional freedom

to extreme overclockers with new custom design MSI graphics cards. Now MSI

Afterburner is able to control up to 3 voltages on custom design MSI Fermi

and other future custom design MSI graphics cards. New adjustable voltages

include memory voltage and special multi-purpose auxiliary voltage feeding

either memory bus (also known as VDDCI on AMD graphics cards) or PCIE bus

and crystal (PEXVDD on NVIDIA graphics cards)

Thanks as well, decided to up all the voltages anyway as they are as marsey said at the max safe voltage that way.

i am waiting for my 580 lightning to arrive in the next week...are you sure its safe to slide everything to the end ? Can you post a screenshot of your voltages or let me know what they are set at on full ?
