Review: 1120MHz GPU out of the box

The card we’re talking about today is called Radeon XFX Black Super OC DD Radeon 7770 1120M 1GB D5 2Xm DP HDMI DVI (part number FX-777A-ZDSC). You recognize the Double Dissipation Cooler easily - it has two fans. It’s important to differentiate this card from FX-777A-ZNB4 and FX-777A-ZNBC which is also called Radeon HD 7770 Black Edition but doesn’t have the Double Dissipation moniker.

XFX has yet another Black Edition Double Dissipation graphics card (part number FX-777A-ZDB4 and FX-777A-ZDBC), but which runs at 1095MHz, i.e. has no Super OC moniker.

The HD 7770 Black Ed. Super OC's cooler comes with a nice aluminum frame and the two fans will ensure stable operation of the overclocked GPU. We must admit that XFX HD 7950 Black Ed. DD card is still our favorite when it comes to cooler styling.

Radeon HD 7770 Black Edition Super OC draws power via one 6-pin power connector. 

On the next picture you can see the Radeon HD 7770 Black Edition which uses single fan cooler (777A-ZNB4).

HD 7770 Black Edition Super OCs cooler uses a large copper plate which is connected to the heatsink, although the memory is cooled only by air. XFX used the GDDR5 memory made by Hynix ( model number H5GQ2H24MFR-T2C). These models specified to run at 1250 MHz (5000 MHz GDDR5 effective).

The card uses IP5X Dust Free fan and XFX Bracked Design.

The card has one dual-link DVI out, one standard HDMI and two mini DisplayPort outs. Users will get HDMI to DVI converters, but we didn’t find any DisplayPort converters in the package. 

The card is 21cm long, and you may combine this card with another HD 7770 card from any vendor in a CrossFire configuration.
