ASUS EAH4770 FML/DI/512MD5/A Radeon HD 4770 Videocard Review

ASUS EAH4770 FML/DI/512MD5/A Radeon HD 4770 Videocard Review  - PCSTATS
Abstract: Once the box is open it's clear Asus has made some big changes from the reference Radeon HD 4770, starting with the heatsink. Asus claims its new design will increase airflow volume and improve heat dispersion, but it's hard not to notice that the fan shroud resembles a Formula 1 racer.

ASUS Overclocking Challenge - the Radeon HD 4770, Test Specs

Overclocking Results:
Stock Overclocked
GPU Speed: 750 MHz 830 MHz
Memory Speed: (800) 3200 MHz (850) 3400 MHz
If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

The ASUS EAH4770 FML HTDI/512MD5/A videocard ships with its ATI 'RV740' GPU running at 750MHz and 512MB of GDDR5 memory clocked at a respectable 800MHz, or effective 3.2GHz (quad-pumped).

As always, PCSTATS overclocked the videocard through ATI's Catalyst Control Center using ATI Overdrive. The fan was set to run at 100% from the start and PCSTATS started with the GPU first, pausing to test the results with a quick 3D benchmark before continuing. We take note of any stability problems or artifacts, then list the maximum stable and artifact-free overclocked speed the videocard achieves. The same process is repeated with the memory, then both GPU and memory are overclocked together.

ASUS' EAH4770 FORMULA is a mainstream videocard, which generally means good overclocking is to come. Unfortunately the overclocking sliders in ATI Catalyst Control Center don't have all that much range... in fact the GPU could be overclocked to a maximum of just 830MHz.

Considering this, we didn't bother increasing the clock speed in small jumps, and instead went right for gold. The Radeon HD 4770 was pushed from its default of 750MHz right to 830MHz in one fell swoop. The graphics card handled this without breaking a sweat - no visible artifacts or instability.

The memory options were similarly limited by ATI Overdrive, so with the GPU back at stock speeds the 512MB of GDDR5 memory on the ASUS EAH4770 FORMULA was aggressively overclocked right to the max - 850MHz.

As you might have already guessed, without any effort PCSTATS was able to overclock ASUS' EAH4770 FORMULA videocard to 830MHz GPU / 850MHz memory. A nice videocard overclock sure, but I couldn't help thinking that the Radeon HD 4770 has a lot more headroom to spare...

Prelude to Benchmarks

The details of how the Asus EAH4770 FORMULA videocard was configured for benchmarking; the specific hardware, software drivers, operating system and benchmark versions are indicated below.

All benchmarks for the videocard were run in Windows Vista Ultimate, the reference video cards were tested in both Windows XP and Vista for the DX10 benchmarks.

PCSTATS is in the process of making the transition to a Windows Vista and Intel CPU test platform, so keep this in mind as you scan the benchmark results. In the second column are the general specs for the reference cards this ATI Radeon HD 4770 videocard is compared against.

Benchmark results are organized by GPU manufacturer first (ATI/ATI or nVidia), then by GPU generation, and then by GPU class (high end, mainstream, value). This approach provides a clearer view of how performance can differ from generation to generation, and class to previous generation. The product being tested is marked with the red colour bar.
