Just looking at the video card one can tell just how beefy the cooling system is and see that it must consume some power as it has two power connectors located along the top edge of the card. The ATI Radeon HD 3870 X2 graphics card requires a minimum 500W or greater system power supply for single card operation. Since the board power usage is less than 225W only the two 2x3 PCI Express power connectors are requierd in normal operation. The 2x4 PCI Express power connector may be needed for overclocking, so keep this in mind if you plan on overclocking. For running a pair in CrossFireX it is unknown what the requirements will be as ATI has not made this information public since the CrossFireX drivers are still in development.

Ok... big issue: My card just overheated!

I was playing COD4 at 1920x1200 with settings maxed (as I could do regularly with my 8800GTX)

Next thing you know... black screen and crash! I had to restart.

I moved my soundcard down to the bottom so the video card doesn't have anything around it, but the black metal on the back was super hot to the touch...

Well I purchased WIC today, last time I tried the game was the demo with my opty 185 @3ghz and my ultra, well with this X2 I have everything on Ultra High and WOW no lagg at all.

Only problem is my temps, it causes artifacts but I increase fan speed with rivatuner to 100% and they go away and runs ultra smooth. I love this card!

Now to find a custom cooler....

You have to put in a new .cfg file in your install folder.

I have the updated .CFG for our cards, if you want it. I will try to find somewhere to upload it, but PM me and I can email it to you.

EDIT: Heres the updated .cfg file. Just paste it to "C:\\Program Files\\RivaTuner v2.06" and yes to overwrite.

Still another crash while playing COD4... hmm.

Something's going on with this card. I'll need to do more testing.
