14 DAY TRIAL // AMD's release of the Radeon HD 7790 graphics card wasn't one of those product releases where none of the company's partners were allowed to modify the design.
That is why Gigabyte felt free to overclock the board and use a different PCB and cooler, and why Micro-Star International did much the same thing.
In the photo above there is none other than the R7790-1GD5/OC, an MSI HD 7790 with a clock speed of 1050 MHz instead of 1000 MHz.
The 1 GB of GDDR5 VRAM is left at its normal frequency of 6 GHz.
MSI's card, like the standard-clocked one, has DisplayPort 1.2 and HDMI 1.4a outputs, plus two DVI ports, more than enough for Eyefinity.
As for the cooler, it includes a large fin array and a 100 mm fan with Propeller Blade technology. It will keep the adapter within safe temperature limits even when the MSI Afterburner software is used to overclock it. Within reason, of course.
