Kingston HyperX PC3-17066 (2133MHz) 4GB Kit - Overclocking

2133MHz DDR is a bit of a pain in the butt number. The problem is that we find ourselves at 4.5GHz or 3.7GHz due to the multipliers. We did opt for the higher speed first, but didn't have any luck getting into Windows at 2133MHz DDR 9-9-9-27.


In hoping it was going to be no fault to the modules themselves, we tried the 178 BCLK and we got into Windows without an issue. It's a little bit of a pain, but it's no fault to Kingston; it's more a multiplier issue.


The problem is that if the kit was a 2000MHz DDR one we could set our BCLK at 200 which would push the CPU speed up while keeping the memory at that 2000MHz DDR number. Instead, while we have more MHz on the RAM, we have had to drop off the CPU MHz which can skew our results slightly. We'll talk about that more in our benchmarks, though.




You can see the validation here.


In the end, getting to 2133MHz at 9-9-9-27 wasn't an issue when we calmed the CPU down. We didn't expect anything less from Kingston, so getting the stock clocks out of the box with no issue came as no surprise.




When it came to overclocking we had some joy increasing the clocks from the standard 2133MHz DDR. Keeping the timings the same, we managed to achieve 2274MHz DDR which is a good 140MHz DDR over the default speeds.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the memory. 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.
