Since the launch of Intel’s new X99 platform we’re rather busy testing CPUs, motherboards as well as DDR4 memory. One part of the story is about finding out what DDR4 can do when it meets liquid nitrogen and it turns out that ocaholic’s Hiwa managed to break the overall memory bandwidth world record in AIDA benchmark.
If you take a closer look at the screenshot below you will notice Hiwa managef to score 83’460 MB/s memory read speed and 78’216 MB/s write speed. In order to do so he had to push the G.Skill DDR4 kit (F4-3000C15-16GRR) to 3.0 GHz and reduce the latency to CL 11-14-16-15 with tRFC at 270 and command rate 1T. Also note the NB (Uncore) frequency which is almost 5.0 GHz. Apart from the uncore running highly overclocked the CPU was clocked at 5’124.91 MHz and CPU cooling was handled with liquid nitrogen. In this case the memory was capable of doing the job aircooled. All this hardware was installed on an ASUS ROG Rampage V Extreme motherboard and powered by a Seasonic Platinum Series 1050 Watt power supply.
We’re quite sure more scores are to follow this week since Hiwa will be spending some more time benching Haswell-E and DDR4 with liquid nitrogen.
