Diamond Radeon HD 6770 XOC 1GB Video Card Review
The Card
Moving out of the package and onto the card, you can see that Diamond have opted to use a larger single heatsink/fan setup that sits in the middle of the card verses a cooler that covers the majority of the card.
Taking a spin around the card, we can see at the back of the card we've got a single 6-Pin PCI-E power connector. Moving across the top and closer to the front, you can see we've got a pair of CrossFire connectors.
Checking out the I/O side of things, we can see we've got two DVI connectors along with a single HDMI and full size DisplayPort connection. Nothing too unusual here with the same connection setup we see on just about every other HD 6770.
Specifications
With the XOC tag present on the card, that of course means we're dealing with an out of the box overclock. Just what kind of overclock? Well let's fire up GPU-Z and take a closer look at it.

Looking above, you can see that Diamond has chosen to boost the clock speeds on both the core and memory. You can see our core has been bumped up to 900MHz from the default 850MHz while the 1GB of GDDR5 has gone from 4800MHz QDR to a nice round sounding 5000MHz QDR.
