HIS Radeon HD 7950 review

AMD allows you to opt for the multi-GPU road with Crossfire(X) as an option. You can pair two, three or even four cards in one PC and have them do a decent workout. By the way I get this question all the time, but Crossfire is setting the same cards up in multi-GPU mode, and CrossfireX is mixing different cards say 6950 and 7950 and set them up in Crossfire mode.
If you peek to the right of the PCB on the photo in-between the 1 and 2 position you'll notice a Switch, it's actually a Dual BIOS toggle switch. Setting two returns the card to factory default, setting 1 is an unprotected mode which allows you to overclock and tweak while mode two is your failsafe BIOS.

The reference R7950 has a maximum power consumption of roughly 160 Watts, our measurements actually show numbers below that value. The boards overall power consumption from idle to load is excellent really.
Mind you that the maximum board power is 200W. At default AMD PowerTune settings you can deduct 20% from the maximum board power, and that results in a 160W TDP.
You will need to hook the card up to your power supply with two 6-pin PCIe PEG connector. We recommend a 500W power supply to start with, with one card of course.

Connectivity wise the output connectors will vary per brand. But on this card we see four connectors supporting all high-resolution monitors. We get two display port connectors (mini), HDMI and a DVI connector. The cards will come with monitor connector dongles and adapters.
Overall the card remains cooled within very acceptable limits and it isn't too noisy either. But you'll learn all about that over the next few pages.
We test and review the a HIS Radeon HD 7950 HIS IceQ X, this 30 CM sized beast is one heck of a graphics card. Custom PCB, custom cooling, it's low noise and being a Boost edition card series, it clocks in at 950 MHz.
HIS Radeon HD 7850 4GB iPower IceQ Turbo review
We test and review the a HIS Radeon HD 7850 iPower IceQ Turbo as single card and in Crossfire today. The HIS Radeon HD 7850 iPower IceQ Turbo is a factory overclocked 4GB version of the Radeon HD 7850 graphics card.
HIS Radeon HD 7970 X Turbo edition review
We review the HIS Radeon HD 7970 X Turbo edition. With this card they took the new Tahiti XT2 and redesigned the R7970 board from ground up. though very long the end result is a 31cm PCB with mane power phases and optimizations. Fun to see are the voltage and FAN monitor LED options. Most impressive however is the sheer amount of monitor connectors HIS injected into this product, four DisplayPort connectors, one HDMI and a DVI connector. If needed you can go for Eyefinity6. Oh did I mention already that the factory set boost clock frequency is 1180 Mhz ?
HIS Radeon HD 7950 ICEQ Turbo review
We review the HIS Radeon HD 7950 IceQX Turbo. The product comes factory overclocked very nicely for you as it is running a gentle 900 MHz clock frequency. HIS uses a custom PCB and dual-slot cooler making the card very easy to install. Despite that factory overclock and that cooler the noise levels remain at very low levels whereas the GPU temperatures remain downright excellent as we'll show you in this review.
