Corsair Dominator Twin2X2048-8888C4DF

Xvid Encoding:

We tested video encoding performance using VirtualDub-MPEG version 1.6.15 and a multithreaded version of the Xvid codec, along with the LAME MT MP3 encoder for encoding audio. We did a two-pass encode of a 15-minute 276MB digital TV recording with a target file size of 100MB.

Over the course of our 15-minute benchmark, we saw an improvement of 3 seconds at the same memory bus speed and tighter timings. There were other things affecting the performance when the memory was running at its rated 1111MHz frequency.

MP3 Encoding:

We used LAME MT for our audio encoding test - it's the multithreaded version of the popular LAME MP3 encoder. We ran tests with both Intel's and Microsoft's compilers - naturally, the Intel compiler resulted in some performance increases on Intel's processors. We converted all 18 tracks from Moby's popular Play album to a 192kbps variable bit-rate MP3.

The tighter timings on the Dominator memory made little-to-no difference in our MP3 encoding tests, but there was a slight MP3 to WAV decoding performance improvement when using the Microsoft compiler.
