Can't switch between multiple GPUs

[izedgo]

I have two ASUS R9 270x, but in GPU Tweak I only see one card.
How to control voltage on the second card?
Moving mouse under GPU name not works.

Thanks!

Sensors section or you can read a review of your card.

Holy crap, if that works, you are a life saver. I will test that for my Matrix 7970ghz - The most frustrating thing ever has been not being able to control voltage in afterburner, as if you don't downclock the memory speed and voltage it artifacts.

hum doesn't show it in the sensors section of mine. just says 'ATI internal'.

Post your screenshot. Or simply write model of your videocard.

It's a 280x matrix platinum. Not sure where I got that ATI internal info from, must have been something else I was trying to detect the sensor with.

It's CHiL 822*. My friend tried to do this on his 280x matrix, but no results :(. Waiting for new GPU Tweak.

yeah gpu tweak just crashes the card for me if i try to change anything.

My find is that when "Crossfire" is enabled GPU Tweak let's you switch between GPU's but when it's disabled it does not.

i have 2 5870 and 2 r9 280x matrix installed in my pc. and when i crossfire the 5870's i can select. same if i crossfire the 280x's and enable it.

but i want to be able to select all gpu's without crossfire enabled. for obvious voltage controll.

MSI Afterburner 3.0.0 Beta 18

Added low-level I2C access driver for AMD Bonaire, Curacao and Hawaii graphics processors. Low-level I2C access driver provides much faster access to I2C bus than ineffective native AMD ADL I2C access interface and addresses issues with GPU clock throttling when enabling voltage monitoring on AMD RADEON R9 290 series graphics cards

Improved AMD ADL access layer with Overdrive 6 support to provide compatibility with future AMD GPUs

Regular and SE versions of MSI Afterburner are now merged into single installer. Added voltage control mode selection option to the “Compatibility properties” section in “General” tab. Now you can toggle between reference design, standard MSI and extended MSI voltage control modes

Added “boost edition” / ”GHz edition” GPU type selection option for reference design AMD RADEON 7970 and AMD RADEON 7950 based graphics cards to “AMD compatibility properties” section in “General” tab

Added GPU usage averaging algorithm for Overdrive 6 capable AMD GPUs. Now displayed GPU usage is being averaged by sliding window to smooth GPU usage artifacts occurring due to bug in AMD ADL API on AMD Sea Islands GPU family

Added optional unified GPU usage monitoring path via D3DKMT performance counters. Power users may enable it via configuration file as a workaround to replace native vendor’s GPU usage monitoring if it is working improperly (e.g. broken GPU usage monitoring in AMD ADL API for AMD Sea Islands GPU family)
