Difference Between Core Clock and Memory Clock and Power Limit?

post #1 of 4
Thread Starter 
7870 XT CLUB 3D JOKER

After doing some overclocking and found stability, I now want to know more about these below that I get when lunched MSI afterburner. I uses Prime95, msi kombuster, cpuz, hwmonitor, system monitor.

Using MSI afterburner my GPU has:

Core Voltage- which is not adjestable or accessible
Power limit(%)- which is at +0 at the moment even though I have OC.
Core clock- overclocked to 1200 by user/ me
Memory clock- overclocked to 1600 by user

I want to know what these are, how to adjust them effectively and what they can do including what they are ACTUALLY there for, if necessary. smile.gif

They are what they sound like they are.

 

-Voltage fed to the gpu - if the card isn't voltage locked through the card's bios and actually has voltage control you can increase the volts and possibly get a higher OC (You'd need to unlock the option in the settings to access the voltage slider through AB - again, this is dependent on whether or not the card supports it)

-How much power can be fed to the gpu (default is 100% and usually lets you push an additional 20%) - more power = possibly more OC

-Operating frequency of the gpu - higher clock = higher performance

-Operating frequency of the memory - same (minuscule benefit tho)

 

Increasing any of these(especially the first two) generally increases heat as well.

I think my voltage is locked. I will use the power instead. I think I have the power option because my voltage is locked. That could mean I can still overclock higher as if the voltage was not locked?

It'd be pretty limited without voltage control.
