طبق اطلاعات موجود مدل های رفرنس حداکثر تا 925MHz برای هسته قابل اورکلاک هستند ولی Asus تا 1035 هم جواب داده .لذا تقریبا همه بردهای این مدل قابلیت Voltage Tweak رو دارند .

Performance Boosts with Voltage Tweak and Extreme Overclocking with SmartDoctor
The ASUS EAH5870/2DIS/1GD5 and EAH5850/2DIS/1GD5 are equipped with Voltage Tweak technology, as part of the SmartDoctor application. It enables users to raise GPU voltages from 1.15V to 1.35V and from 1.088V to 1.4V respectively, boosting GPU and memory clock performance from 850 / 725 MHz to 1035 / 1050 MHz and from 4800 / 4000 MHz to 5200 / 5200 MHz respectively. Such extreme performance upgrades raise the EAH5870 and EAH5850’s 3DMark Vantage Extreme Preset score from 8,087 to 9,252 and from 6501 to 8987—an unbelievable 17% and 38% improvement compared to other reference designed boards*. Gamers and overclockers can also benefit from ASUS SmartDoctor, the world’s first overclocking utility that allows the tweaking of GPU voltages on the EAH5800 Series graphics cards. ASUS SmartDoctor enables users to boost both voltages and overall performance with just a few clicks—without the hassle of flashing the BIOS or running the risk of damaging the graphics card
