HIS R9 280X iPower IceQ X2 Turbo Boost Clock 3GB Video Card Review

Videocards/VGA Reviews by stefan @ 2013-10-22

HIS has made available to the market the latest R9 280X from AMD in two revisions quite quickly, which are fitted with the efficient IceQ X2 two-slot cooling system. The HIS Radeon R9 280X IceQ X2 Turbo Boost card is available online for an affordable price and comes with a factory overclock of 50Mhz over the stock version; the VRM section has been also beefed up in order to be able to reach higher GPU frequencies.

Internals Explored

In order to get access to the top side of the PCB, we will first have to remove the GPU backplate which is held with four spring-loaded screws:

 

 

 

The cooling system can be removed quite easily after this step and we will also reveal the metallic front plate which covers most of the card surface and helps eliminate heat from all the components. In order to disassembly this one too, we will have to remove 10 extra screws from the back (however, there are two extra which link the plate to the I/O shield). Using a plate like this greatly improves the durability of the board since PCB flexing is not present:

 

 

 

After the previously mentioned screws have been removed, we must lift off the plate little-by-little so the thermal pads won’t get damaged in the process:

 

 

 

The card is equipped with 12 SKHynix H5GQ2H24AFR GDDR5 SGRAM memory chips which total 3GB on a 384-bit Bus and are rated for 1.5V at 6Gb/s speed:

 

 

 

The board is also equipped with a 7+2 PWM design, 7 for the GPU and 2 for the memory. This design is very welcome for achieving better overclocks since the stock version only comes with a 5+2 variant:

 

 

 

The VRM section is driven by the well-known CHiL 8228G controller, which we have found on other cards in the past:

 

 

 

In the bottom right corner we will get to see the PWM fan header, which powers both 89mm fans:

 

 

 

 

Near the GPU we will find some rubber spacers which will also help avoiding scratches in the nearby area when fitting the heatsink:

 

 

 

The GPU is fully polished, without no markings at all, same situation as we have found with the HIS 7950:

 

 

 

The heatsink is quite massive and as we have mentioned before, we are dealing with 5 heatpipes, two which are 8mm in size and the rest are 6mm:

 

 

 

The GPU copper block is nicely milled and around it we can find a second set of transparent plastic spacers:
