The card also carries memory and mosfet heat sinks to provide extra heat dissipation from these areas.The extra large 40x47.5mm copper heatsink provides a large area to dissipate heat efficiently.The 2x 8mm and 3x 6mm wide heatpipes optimize cooling performance by removing heat from the core area.The fan is extremely durable with a life span of up to 50,000 hours.The Q&C fan blade increases air velocity make cooling more efficiently while keeping noise level at minimum.The super large 2x 89mm dual axial fans draws massive amount of cool air to cool the GPU directly.The card remains quiet whether you are gaming, online socializing, entertaining or working. The card is below 28dB when watching movies, surfing Facebook, working. IceQ X² is one of the quietest coolers, making the card quieter than the reference cooler. With IceQ X², the card is cooler than the reference cooler. IPower design allows the card to carry more voltage, expanding overclocking capability to a new level! don't use Furmark, it'll burn up your GPU.IPower for More Voltage, More Overclocking With that said, can u flash the BIOS back to the original and maybe put up a GPU-z screenshot of the VDDC?ĭo u have a uefi or legacy bios and which version? iirc the dual-x is an anomaly, I think it has an unusual vrm controller. Increasing the limit can prevent throttling but also make it worse. There is a TDP limit programmed into the bios which varies between GPU's, it may or may not reflect what the vrm's can take. Vrm's have a wattage, heat, and voltage tolerance before throttling or damage occurs. The ASIC value in GPU-Z relates to current leakage, basically GPU efficiency.ġ00% ASIC all power from vrm's gets to the GPU, by the time you get to 50%, your vrm's are drawing 300w and sending half of it into space.Ī 50% ASIC GPU pulls double that of a 100% ASIC 1000mhz GPU. This can be changed in the config file if you know how. (Example: I raised mine from 1.188 to 1.200)Ĭlick to expand.Can I give you some friendly solid advice: please don't mess with the BIOS till you understand it.unless you'd like a fried video card.ĪB by default displays VID, which is not the same as vgpu. You can raise the #0 Core Clock voltage just one tick. Tick and untick the 'Manual power adjustment' in VBE7, so it can calculate the power limt, after changing TDP(W) above. (Example: My card has one 6 pin connector, so my TDP limit is 150 w minus 20% equal 125 w).

This is the max TDP for your card, without the plus 20% in afterburner. You can add up your power connectors plus the PCIE and withdraw 20%. PCIE and 6 pin connectors can handle 75 w each. Do NOT raise the voltage, neither the TDP to high. Only edit your own bios and flash it back. But do NOT flash any other bios to your card. My #0 Core Clock voltage was also a bit lower, at minimum. My TDP(W) was the lowest of all cards (108 w). I compared my Sapphire bios to all available R9 270 bios at TechPowerUp. Beyond 60 dregrees (celsius) it was throttling very fast. Are you capable of editing and flashing the GPU bios? I had a similar problem with my R9 270.
