How tight can we get the timings on the Kingston HyperX Predator 16GB 2400MHz DDR4 memory kit and how far can it be overclocked with 1.35V of memory? We wanted to see just how much overhead Kingstdon left in the HyperX Predator DDR4 HX424C12PB2K4/16 memory kit, so we gave it our best shot.
We started out trying to tighten the timings on the HyperX kit as much as we could. We were happy to find out that we could get down to 12-11-12-24 with a 1T command rate at 2400MHz. This kit started out at 12-13-13-35 2T, so this isn’t too bad. We had high hopes of getting CL11 timings at 2400MHz, but it wasn’t meant to be as our system would fail to successfully load Windows 8.1 when we tried to get CL11 working. All testing was done as 1.35V in case you are wondering if we pushed the voltage up.
At 2666MHz we were hopeful we would be able to get some CL12 timings going, but we had to settle for looser CL13 timings. Being able to overclock this kit up to 2666MHz with 13-13-13-28 timings and a 1T command rate is still very good though.
Things started to get very unstable when we pushed for 2800MHz and 3000MHz on our memory kit with using both a 100MHz and 125MHz base clock on this particular memory kit. As a last ditch effort we increased the DRAM voltage up to 1.50V with the kit at 3000MHz with 15-16-16-25 2T timings and was unable to get the system to successfully load Windows. It looks like Kingston has been doing some sorting and that not all of their kits will do 3000MHz. We are still happy to get up to 2666MHz with CL13 timings though and if you wanted to loosen the timings up to CL15 we were able to get up to 2800MHz although it wasn’t rock solid.
