Early this week at the Intel Developer Forum in San Francisco, California G.Skill showed off new low latency DDR4 memory modules for desktop and notebooks. The company launched two Trident series DDR4 3333 MHz kits and one Ripjaws branded DDR4 3333 MHz SO-DIMM. While these speeds are not close to the fastest we have seen from them, these modules offer much tighter timings. All of the new memory modules use Samsung 8Gb chips and will be available soon.
On the desktop side of things, G.Skill demonstrated a 128GB (8x16GB) DDR4-3333 kit with CAS latencies of 14-14-14-34 running on a Asus ROG Rampage V Edition 10 motherboard with an Intel Core i7 6800K processor. They also showed a 64GB (8x8GB) kit clocked at 3333 MHz with timings of 13-13-13-33 running on a system with the same i7 6800K and Asus X99 Deluxe II motherboard.

In addition to the desktop DIMMs, G.Skill showed a 32GB Ripjaws kit (2x16GB) clocked at 3333 MHz running on an Intel Skull Canyon NUC. The SO-DIMM had timings of 16-18-18-43 and ran at 1.35V.
Nowadays lower latency is not quite as important as it once was, but there is still a slight performance advantage to be had tighter timings and pure clockspeed is not the only important RAM metric. Overclocking can get you lower CAS latencies (sometimes at the cost of more voltage), but if you are not into that tedious process and are buying RAM anyway you might as well go for the modules with the lowest latencies out of the box at the clockspeeds you are looking for. I am not sure how popular RAM overclocking is these days outside of benchmark runs and extreme overclockers though to be honest.
Overclocking Innovation session at IDF 2016.
With regards to extreme overclocking, there was reportedly an "Overclocking Innovation" event at IDF where G.Skill and Asus overclocker Elmor achieved a new CPU overclocking record of 5,731.78 MHz on the i7 6950X running on a system with G.Skill memory and Asus motherboard. The company's DDR4 record of 5,189.2 MHz was not beaten at the event, G.Skill notes in its press release (heh).
Are RAM timings important to you when looking for memory? What are your thoughts on the ever increasing clocks of new DDR4 kits with how overclocking works on the newer processors/motherboards?
