HIS R9 280X iPower IceQ X² Turbo Boost 3GB Graphics Card Review
Overclocking
Apart from the Sapphire R9 280X Toxic the HIS iPower IceQ X² Turbo Boost R9 280X was the best overclocker we had. I was actually quite surprised so checked a few other reviews to see they also had similar results. That said if you’re looking for a beast of a R9 280X overclocker then this card is exactly that. The memory overclocking was a bit weak but we were able to reach 1725MHz (6.9GHz effective) though it wasn’t able to hold that when paired with the GPU overclock which was a tad strange. If we lowered the GPU clock back to 1180MHz the memory was stable at 1725MHz but the card is actually faster with 1190/1655 than it is with 1180/1725 so we stuck with the higher core clock.
Summary of overclocking results in our R9 280X reviews:
- HIS iPower IceQ X² Turbo Boost R9 280X – 1190MHz core and 1655MHz memory
- Club3D royalKing R9 280X – 1165MHz core and 1650MHz memory
- Sapphire Toxic Edition R9 280X – 1230MHz core and 1800MHz memory
- XFX Double Dissipation Black Edition OC R9 280X – 1125MHz core and 1735MHz memory
- Sapphire Vapor-X OC R9 280X – 1160MHz core and 1600MHz memory
With the second highest core overclock the HIS R9 280X was unsurprisingly the second fastest R9 280X we’ve tested.
