Curious to find out how much power benefit we’d extract from low-voltage SO-DIMMs, we needed a test platform that supported both 1.35 V and 1.50 V standards. That meant deviating away from a mobile or embedded Haswell-based CPU, since those only support 1.35 V modules. A member of its M8 barebones PC kit, ASRock’s Z87-M8 motherboard supports both voltage levels on two SO-DIMM slots by using a socketed processor.
We’ve heard that SO-DIMMs aren't very overclockable, but G.Skill is confident that its modules have headroom to spare when they're paired with an LGA 1150-based platform. While we weren’t able to follow through with a stable 2133 MT/s data rate, we were at least able to use the higher 1.50 volts to push CAS 9 timings.
Everything I’ve read so far lead me to believe that lower thermal and power limitations would slow the embedded version of Intel’s Core i7-4770 by up to 5%. Conversely, I’ve also been expecting that the company's Iris Pro graphics 5200 would deliver about 20% additional performance. The only problem is that CPU model doesn't let us compare different memory voltage levels. Moreover, I didn't have one at my disposal.
That is, until something "fell out of Gigabyte’s trunk" following BlizzCon. This thing packs the wallop of a huge copper sink to prevent thermal throttling, along with support for both 2.5” and mSATA SSDs. Those two advancements roughly doubled the thickness and weight of this enthusiast-oriented Brix compared to familiar models.
