Our overclocking results with the PC2-6400 ReaperX series were extremely impressive. Designed to run at a stock speed of DDR2-800MHz or 400MHz core speed, we managed to push the modules to DDR2-920MHz with the stock 4-4-3-15 timings. Lowering these timings to 5-5-5-15 with 2.0v allowed us to reach 528MHz.
We didn’t manage to get any higher with extra voltage which gives us the idea that these modules top out around 530MHz, and without requiring any extra voltage you keep your warranty at high speeds. Increasing voltages may help trying to reduce latencies at higher clock speeds, but we didn’t have enough time to test this theory out.
Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren’t able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. “Burn-in” time might also come into play if you believe in that.
