Review: With silent and powerfull Double Dissipation cooler


Overclocking

XFX DD Radeon 7750 800M 1GB is not a factory overclocked graphics card. The GPU runs at reference 800MHz and the memory at 1125MHz (4500MHz effectively). ATI Overdrive supports GPU overclocking for DD Radeon 7750 800M cards but the limit fort the GPU clock is set at 900MHz. In order to overclock the card beyond 900MHz, we used MSI's Afterburner.

The fan remained quiet after overclocking and although we tried speeding it up manually in order to squeeze a few more MHz over 920MHz, it appears that the final limitation was not cooling but the chip itself. Still, we were quite pleased with the result because we could play most games at 1920x1080.

Thermals and Noise

XFX fans are designed to use linear fan speed ramping controls so that fan speeds and temperatures are optimized to reduce excess noise. This helps by preventing sudden fan speed changes that tend to get loud. The XFX DD Radeon 7750 800M's cooler is great - thermals are good and the card is almost inaudible all the time.
