HIS HD7870 Fan GHz Edition (H787F2G2M)
Jun 6th, 2012 | By JaredThe HIS 7870 Fan is a two slot design so like most cards these days you will lose the slot right next to the PCI-E slot the card is installed in.
After installing the HIS 7870 Fan and setting up the iTurbo application it was time to get to some overclocking. The 7870 Fan comes clocked at the stock AMD settings of 1000 MHz core and 1200 MHz memory clocks. I used HIS’s iTurbo utility to up the core and memory clocks. One thing we saw missing from the HIS 7850 Fan card was the ability to tweak the voltage which is available for the 7870, however for this review I left the voltage settings at the default value. I also left the fan settings at stock and was able to up the GPU clock all the way to 1200 MHz and the memory clock to 1350MHz. I got a solid 200 MHz increase on the core and the identical increase up to 1350 MHz that we saw with the HIS 7850 Fan. I want to mention that these were the max stable clocks that passed all benchmarks without any voltage tweaks. I was actually able to push the card higher and it passed most benchmarks but failed a few, so with some voltage tweaking I think this card might have even more room up its sleeve.
I left the fan at the stock settings and it never was audible over any other components with the tower next to me on the floor. I have included the temperatures from the HIS 7850 Fan testing for reference, and while the 7870 does run hotter it’s to be expected with the higher clocks. Temperatures did increase a little while overclocked but not enough to really be concerned and I never had the fans increase in speed to any noticeable level.
Now that we have seen how far we can push the HIS HD 7870 Fan 2GB card, we are going to throw it through some benchmarks. Below are the system specifications that will be used for testing.
