I recently just installed an MSI Radeon HD7770 (R7770-2PMD1GD5/OC) into my system and I just have a question. When checking the device stats using AIDA64, I realized that my GPU clock is running at 300 MHz and it says after that (original: 1020MHz). Now, my card was called the GHz edition, so I had assumed that that would be the clock speed it is running at, but it seems to like this instead for some reason. I have never messed with adjusting GPU clock speeds (only CPU) and I was wondering if I should raise it to improve the performance of my GPU, or if there is a reason that it is set so low. Any input would be great and thanks in advance.
ALSO: I should note that this is a PCI Express 3.0 card and I am running it in a PCI Express 2.0 slot. I am not sure if that in any way effects what the GPU core clock can run at, but I figured I would add that just in case it does.
just like cpu's, gpu's can lower the clock when it is idle, to save power and lower temp
So, if I start running a game, or some other GPU intensive program, I should see the core clock speed increase? I tried installing MSI Afterburner, and it said I had my GPU clock set at 1020MHz, although in it's monitor, it never went above 300. I even slid it down to 700 MHz and hit apply to see if it made any changes, and nothing.
