4870 core clock can't go over 500 MHz!!!

I haven't tried messing with fans yet, since I can't in Catalyst, but I don't think that would impact this anyways, as stock should be 750 regardless.

Just a note, my power supply came with two six pin power connectors, and each of those had an additional separate (and optional?) 2 pins connection that could pair up with the main six. I obviously did not use either of the additional 2 pins since the card takes 2 six pins and not 2 8 pins. On each of the main 6 pin connectors, it says PCI-E, which is exactly the slot my card is in. So, I think I did everything correctly in connecting the power supplies.

And yes, this is my first PC build.

Just making sure I don't leave out any potentially related details.

Ouch

Dude, don't freaking worry about it. It goes back to 3D mode when you play games. There is nothing wrong with it trying to save a little power.

You might want to adjust those fan speeds a little higher.. high 70's at idle is not good at all. Id be scared poop less to have it like that.

Just read this post of yours... first thing you should do with this card is adjust the fan speeds, I'm seeing more and more people end up with dead cards because they want to mess around with the card first. Especially if your OC'ing it to 790 Core!

I'm running CF 4870's and my hottest one idles around 55C other at 47C one is hotter because where it's seated it doesn't have as good of a air flow. If you need to know how to change the fan speed on 2 cards let me know. I have mine set at the fan speed of 55% on both it's the quietest you'll get while keeping them cold enough.
