ASUS Radeon HD 5770 Voltage Tweak: better than the rest?

Review: ASUS Radeon HD 5770 Voltage Tweak: better than the rest?

Voltage Tweak

ASUS introduced the Voltage Tweak range with the Radeon HD 4890 GPU that we took a look at here. The technology's been moved on over to the GeForce line and, recently, employed on the Radeon HD 5800 series.

In this case, the Voltage Tweak edition looks like any other Radeon HD 5770. It also ships at the default frequencies of 850MHz core and 4,800MHz memory. Users need to install the supplied SmartDoctor utility to gain access to the voltage settings.

Driven by software that interfaces directly with the board's VRM, there's no need for a custom BIOS. It has the same v012.012.000.003 as found on other HD 5770s.

Run in the default state, the Voltage Tweak's fan is quiet in 2D, but it does rise a notch or two above what we'd like when rendering games. We'll have to wait for companies to use aftermarket coolers before Radeon HD 5770s become whisper-quiet in operation.

AMD's Eyefinity technology can drive three digital displays concurrently, although DisplayPort needs to be one of those in a three-way setup. Most people will use no more than two, for a dual-monitor desktop, so any combination of digital outputs will suffice.

Priced at £125, in line with other HD 5770s, ASUS's voltage manipulation is the standout feature in an otherwise reference-like design. Let's cut to it.
