The memory overclock was surprising given the lack of cooling on the chips other than airflow but not outstanding, either. Would anyone be able to explain how to overclock an AMD GPU after doing this, specifically the 8970m (R M290X) I am using Sapphire Trixx and the core and memory clocks are adjustable however GPU Voltage and VRM Temperature are N/A. The HIS HD 7870 IceQ X Turbo isn't silent but certainly is quiet and the cooler lets you make the most of the ASIC underneath. So I used Afterburner to: (a) unlock voltage control, (b) disable ULPS and (c) extend official oveclocking limits.

A bit of googling suggested to use MSI Afterburner to enable overclocking / undervolting. Under load is where it really shines, a muted whoosh of air the only evidence it's working compared to the reference design blower fan's whine. I had earlier used Sapphire Trixx for overclocking Radeon mobile dGPU on an older dell machine, but that doesn't seem to work anymore for me. The HIS IceQ cooler is silent at idle clock speeds, keeping the HD 7870 cooler than the reference design heatsink and fan. Once this is done you can close VECC/CCC and open iTurbo to overclock both cards together.Īll our Crossfire results were performed with both cards at the same speeds, with the reference HD 7870 matching the HIS IceQ X Turbo speeds. Once ULPS is disabled, the second GPU can be PowerTune adjusted in the Vision Engine Control Center / Catalyst Control Center. This obviously removes the GCN architecture Zero Core Power feature, and so bumps up idle power use considerably. Overclocking under Crossfire requires the Ultra Low Power State function to be disabled, something that can be done from the iTurbo application. In our extended stability testing, our highest final stable speeds were an engine clock of 1250MHz (13.6% increase over shipping clock, 25% above reference specification speeds) and a memory clock of 1420MHz / 5.68Gbps (18.3% increase over reference speeds). Without memory voltage control, and no heat sinks cooling the BGA memory chips, we topped out well above the rated 5Gbps of the Hynix RAM, at 1425MHz. In our testing we found the voltage wall - the point where small increments in clock speed require disproportionately more and more voltage, was at 1265MHz on the GPU.

The fan profile is very configurable, with fan ramp up full adjustable from 20% to 100% at whichever temperature you prefer. Two custom fan profiles can be created, saved under the Cooler and Quieter presets mentioned earlier. Four OC profile save slots are provided, which can be loaded at startup if required. ITurbo allows for overclocking adjustments of memory and GPU engine clocks, as well as voltage adjustments but not Powertune level. This is a little redundant as the advanced and info options take you to the same place, an info screen of the application. Upon loading, the application presents itself as a disc with four options, offering information, advanced options, a quieter preset and a cooler preset. This appears to be the same core application as Sapphire TRIXX, but with a couple of welcome tweaks.

HIS has their own overclocking software now, known as iTurbo.
