OCZ 3700EB: Making Hay with Athlon 64

AMD Test Results: Stock 3200+ Speed

The first consideration was the impact of memory speed on stock performance. The 3200+ runs at a speed of 2.0GHz with a stock 10x200 ratio. Performance was compared of the standard 10x200 to 8x250, which is also a processor speed of 2.0GHz. With the CPU operating at the same speed, the only influences on performance are the higher memory speed and the higher bus multiplier.

Slower memory timings were required at DDR500 (250x8) at 3-2-3-10 than the 2.5-2-3-10 needed at DDR400 (200x10). Stock HyperTransport was 4X, and this needed to be lowered to 3X at the 250 multiplier. Despite the slower memory timings at 250x8, you can see that the faster memory speed clearly outperforms slower memory speed with a bit better timings.
