ATI 5870 Overclocking with MSI Afterburner (MSI Firmware on the card)

post #1 of 2

The RED points to what that dropdown arrow drops down to show.
All settings are shown in the image.

There are the default overclock settings from MSI Afterburner. I'm wondering what the ideal numbers I should move the clocks to? Also, I need help figuring out what each of the settings MEAN and what they are FOR?

What is:
Core Voltage(mV) :
Core Clock(MHz): GPU Frequency
Shader Clock(MHz): Locked on AMD cards, no way to unlock
Memory Clock(MHz): vRam frequency
Memory Voltage(mV): Locked on AMD Cards, no way to unlock
Aux Voltage(mV):

The BOLD and UNDERLINED ones are unable to be edited according to Afterburner. Is there a way to edit them? If I can edit them, will they help anything for my speeds/ video card abilities?

Can someone please help me with the definitions of each setting and what to do / set them at please?
Once the answers are posted, I will edit my post with answers for future reference from future users with similar questions.

Thank you for your time and help. This will seriously help me out with knowing how to keep my computer safe.

Shader clock is locked to Core clock on all AMD cards, no way to unlock.
Memory voltage is locked, due to the lack of memory VRMs on the card. No way to unlock. +It's useless - GDDR5 gets easily killed even with freq bump, not to mention volt bump.

Core freq is for the frequency of the GPU - the more-the faster, the hotter
Mem freq is the same thing for the vRam - if you have severe FPS drops on high resolutions, bumping this might give you benefit. But vRam gets easily killed, as I already noted.

It's the Aux Voltage I'm wondering about...
