Tom's Hardware Verdict
An old-tech solution to the H370/B360 trouble, Corsair'due south Vengeance LPX DDR4-2666 16GB kit provides improved performance to XMP-compatible Core i5 (or better) locked platforms.
Pros
- +
+ Big performance benefit from dual-rank DIMMs
Cons
- -
- No secondary XMP for DDR4-2400-limited motherboards
- -
- Elevation non-XMP setting is DDR4-2133
Intel's H370 and B360 chipsets instruct its Cadre i5 (and to a higher place) processors to lock out whatever memory settings above DDR4-2666, which is especially unfortunate in a market that's moved fashion past that setting. DDR4-3200 is now mainstream within the enthusiast PC market, and is often treated as such past the retentivity sellers that cater to enthusiasts and gamers. Thus, the all-time manner to get a pinnacle-performing brand new DDR4-2666 kit would be to dial the mode-back machine to 2016 and go the high-performing kit from that fourth dimension. Barring that, Corsair has a workaround.
Tight latency is a great mode to improve retentiveness performance, but the best way is to build with at to the lowest degree two ranks of memory ICs (fries) per aqueduct. The difficulty getting there is that today's integrated circuits are manufactured in 8Gb and 16Gb capacities, and it takes eight of these ICs to make a 64-bit rank. Looking at the mismatched lot numbers, it appears that Corsair dug through its old inventory and found enough mediocre 4Gb ICs to produce an entire run of 8GB dual-rank DDR4-2666 DIMMs for this kit.
Timings of 16-18-xviii-35 appear painfully boring in comparison to modernistic parts, but the dual-rank advantage is and then dandy that we expect a rout with this kit. Unless you know where to find some erstwhile high terminate DDR4-2666, the simply way nosotros can think of to practise improve is to pony up for a low-latency 32GB kit, thereby securing 2 ranks per DIMM and tighter timings.
That said, poor timings aren't this kit's biggest consequence. It lacks of whatsoever non-XMP settings in a higher place DDR4-2133 CAS 15. This specifically applies to the "don't know" crowd: those who don't know if their lath even has an XMP setting, those who don't know that their Core i3 (or below) peak out at DDR4-2400, etc. So we'll say it over again: DDR4-2666 is for Cadre i5 and above; the limit is imposed by non-Z chipsets, and you'll need a lath that supports XMP to enable this kit's DDR4-2666 profile.
Comparison Hardware
The simply surprise for today'south exam is that prices have dropped this week for a few of the kits that started this series. Each kit retains its sectional selling indicate, including the Ripjaws V's low price, the HyperX Predator'south tight timings, the Viper's RGB, and the Ballistix Sport'south broadened compatibility. But the price war gets a little hotter towards the end of our analysis.

One reason the Vengeance LPX'south rated timings are and so terrible is that it isn't using the classic overclocking play a trick on of increased voltage to achieve these: Only the HyperX required the non-stock 1.35V setting so common amidst college-frequency parts. Bumping the other kits up to 1.35V allowed each to back up improved timings, and the Vengeance LPX's gains are most noteworthy with a full three cycles shaved off CAS and 4 cycles off tRP and tRCD. Anyone who needs a primer for how timings piece of work tin scroll to the centre of our PC Memory 101 story.
Criterion Results
Though it has far more latency than its single-rank rivals (see the second second nautical chart), the Vengeance LPX starts off with a huge Sandra Memory Bandwidth advantage. And yes, we practise expect that to show up in real-earth tests. Nosotros should notation that both tests are impacted by latency, but each uses different packet sizes to produce results that are latency-impacted by a greater or bottom degree.
Anyone who's wondered whether EGO-engine games responded better to increased bandwidth or reduced latency demand simply compare these F1 2015 results to our above Sandra tests, keeping in mind what nosotros said nearly packet sizes. he Vengeance LPX also wins on Metro Terminal Low-cal Redux, if admittedly by a little amount.
The big surprise comes from 7-Zip, where the Vengeance LPX's CAS 16 XMP timings perform slightly ameliorate than G.Skill's CAS 15 and slightly worse than HyperX'due south CAS 13. We once again credit the dual-rank configuration. When all three kits are tweaked to CAS xiii, the Vengeance LPX walks away with the victory.
Final Analysis
The Vengeance LPX'south victory falters in value after recent price drops that put 1000.Skill in the frugal client's rigs. 2 ranks per channel even so outrank one in our functioning tests, and those who but cannot bring themselves to pay for 32GB to get dual-rank DIMMs have one clear choice in this Corsair Vengeance LPX kit. Information technology's the clear choice, that is, as long every bit your board back up XMP.
