Normally I don't pay off practically attention to e-mails that hit my inbox from manufacturers claiming that a fated motherboard can overclock a Skylake Core i7 processor the highest, or that they have claimed the 3DMark record. They are in my mind boring marketing manoeuvre that mean little to nada to the consumer.

Closing month I received one such electronic mail from Asrock that nonetheless caught my attention. It claimed their Z170M OC Chemical formula was the only motherboard to support G.Acquisition's Trident Z DDR4-4333 modules. Initially I thought, how useful is that? Are there even any benefits from running DDR4 memory on the LGA1151 platform that high?

For the to the highest degree part we test using DDR4-3000, as IT now and then shows some benefits all over the more typical 2400 and 2666 speeds. Going to 4000 Meitnerium/s (2000MHz) and beyond is a massive increase in frequency (and be) and I struggled to imagine where this would be useful, especially when gaming. On the other hand, curiosity had gotten the better of me...

So I asked Asrock to kindly air on one of their Z170M OC Expression motherboards. Disappointingly, G.Skill didn't consume any DDR4-4333 memory in stock and a month later we are yet to see any go along sale, thusly this news report is appearing more and Thomas More like a marketing exercise.

However, G.Skill did get along aft and say they could provide an 8GB kit of their DDR4-4000 memory which is visible for purchase. It isn't the memorialize setting DDR4-4333 memory, but at 4000 MT/s it doesn't fall far short-dated and will for sure chip in U.S.A a solve denotation of whether or not this kind of treble frequency memory holds any deserve.

Currently there are a couple of DDR4-4000 computer memory kits open from like G.Skill, Corsair and GeIL. Of those G.Skill's TridentZ modules appear to be capable of the best timings at 19-21-21-41 vs. 19-23-23-45 from Corsair, while the GeIL kits are even slacker at 19-25-25-45.

For testing we'll Be using a couple of select applications and games comparing the Core i7-6700K at various retentivity speeds ranging from 2133 MT/s up to 4000 MT/s. Helping to maximize gambling performance will make up a pair of GeForce GTX 980 Ti graphics cards, if they aren't able to feat the potential of DDR4-4000 we fear nothing leave be able to. With that said, let's get down to lin.

Test Arrangement Specs

  • Intel Core i7-6700 Skylake @ 4.50GHz
  • Asrock Z170M OC Formula
  • G.Skill TridentZ 8GB (2x4GB) DDR4-4000
  • 2x GeForce GTX 980 Ti SLI
  • Samsung SSD 950 Pro 512GB
  • Silverstone Strider Series ST1000-G Evolution 1000w
  • Windows 10 Affirmative 64-bit

Memory Bandwidth Benchmark

Protrusive at DDR4-2133 we see a throughput of just 20.4GB/s which isn't icky but less than what we were seeing from the Haswell processors out of the box. Increasing the memory frequency to 2400 MT/s boosted the memory bandwidth aside 12% to 22.9GB/s which is typically what we were first seeing from the Haswell processors.

Going from 2400 MT/s to 3000 MT/s , the speed which we regularly test at, boosted the memory bandwidth by other 20% to 27.4GB/s. Surprisingly taking the next step to 3600 MT/s boosted performance importantly yet again, this time by another 20% equally we hit 33GB/s. Final stop at DDR4-4000 proverb the storage bandwidth reach 35.5GB/s fashioning it 8% faster than the 3600 MT/s shape. Piece theoretical, the primary benchmark shows both predict, shall we go real-world?
