When it came to overclocking, we used an X48 based GIGABYTE X48T-DQ6 motherboard with support for XMP which is what the memory itself supports. We managed to get XMP to work with 1600MHz settings, but when trying for 1800MHz we didn’t have any joy. When we did our manual overclocking we hit a max of 908MHz with the 1.9v rating. Using 2.1v allowed us to move up to 933MHz speeds to load XP, however we didn’t get it to run our benchmarks.
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.
