ATI Radeon HD 5830 1GB DX11 Video Card Review

Radeon HD 5830 Overclocking

To overclock the ATI Radeon HD 5830 1GB graphics card, we used the ATI Overdrive utility that is part of the CATALYST Control Center. When you ‘unlock’ the ATI Overdrive, you can manually set the clock and memory settings or let the ‘auto-tune’ utility set the frequencies for you.

To save on time we skipped the auto-tune feature and just maxed out the sliders and took the card the highest that it could go. We also cranked up the fan to 50% just for fun and to make sure the GPU was as cool as it could possibly get. We started out at the default settings of 800MHz on the core
and 1000MHz on the memory, but were able to reach 875MHz on the core and 1200MHz on the GDDR5 memory with no stability issues. This is a 75MHz overclock on the core
and a 200MHz boost on the GDDR5 memory ICs.

To test out the overclock we fired up 3DMark Vantage and manually
set the fans at 100% just to be sure heat wasn’t an issue when
benchmarking at this overclock.

Running 3DMark Vantage with the Extreme preset we got a score of X6147. The score went up to X6674 3DMarks when overclocked, which was an improvement of 527 3DMarks or 8.6% with this moderate overclock. Let’s take a look at a real game title.

Benchmarking S.T.A.L.K.E.R.: Call of Pripyat showed solid performance numbers and the scores in the day scene increased by 8.7% thanks to the overclock. This confirms the 8.6% performance gains that we saw in 3DMark Vantage, so it’s safe to say performance improvements of at least 9% can be had when overclocking a Radeon HD 5830 graphics card.
