We overclock the HIS HD 7850 and see how much performance we can get out of the model.

The Card

Having a look at the card you can see it features a very plain design. This doesn't come as much of a surprise as it's not part of the IceQ series. You can see we've got a fan in the middle and behind that a big aluminum heatsink with a shroud that covers majority of the card which ultimately hides almost everything.

Looking around you can see at the back we've got a single 6-pin PCIe power connector while moving across the top you can see we've got a single CrossFire connector which gives us the ability to run up to two of these together for extra performance.

Finishing off with the I/O side of things you can see we've got a single Dual-Link DVI connector, HDMI port and two Mini DisplayPort connectors. If you're going to make use of DisplayPort, you'll need to pick up a Mini DP to DP connector, as we saw on the last page, there isn't one included in the bundle.

 

 

Specifications

 

Looking below you can see the default clock speeds follow the reference speeds. That means the core comes in at 860MHz while the 2GB of GDDR5 carries a clock speed of 4800MHz QDR. Using MSI Afterburner, we'll today be seeing what we're able to get out of the card.

Looking above you can see the overclock is pretty weak. We've got 895MHz on the core and our 2GB of GDDR5 has been pushed up to 5060MHz QDR. One of the main reasons overclocking on this model isn't that great is because there's no voltage adjustment.

 

At first we thought that the lack of voltage adjustment was due to the fact that it wasn't ready in the software, but later we discovered the model was just missing the feature.
