Cons: Using XMP to setup the memory at the right speed and timings did not work well at all. Despite resetting the bios to default settings, the system would not post with XMP enabled. It set the timings and the speed correctly, however what it did to the CPU settings was the problem. It lowered the CPU multiplier and the CPU Cache multiplier, disabled turbo boost and lastly changed the BLCK frequency to 125 MHz instead of the stock 100 MHz. The change in BLCK frequency was the reason it wouldn’t post as more settings would need to be adjusted for that to be stable. Now the part that didn’t make sense is why it did that in the first place when configuring all of the settings for this kit manually, the system booted up and was completely stable at 3000 MHz.
Overall Review: To sum things up many people will say that faster ram for situations other than a system with an integrated GPU does not improve performance. However, in this circumstance, using this ram at its rated speed versus stock DDR4 2133 MHz showed increased performance in every benchmark I ran. Despite showing tiny FPS improvements in 3DMark and noticeable gains in Unigine Valley, your money would be better spent on a better CPU or graphics card than high speed memory, unless you’re going to use a ram disk. CPU: Intel i7-5960X @ stock speeds Mobo: Asus X99 Deluxe (Bios: 2001) GPU: Nvidia Quadro K5200 (Driver: 354.42) OS: Windows 7 SP1 x64 DDR4 @ 2133 MHz Timings: 15-15-15-36-2T DDR4 @ 3000 MHz Timings: 15-17-17-35-2T
Pros: Overall, this RAM was very fast and easy to set up with one single XMP profile available in the BIOS. I tested this RAM with an MSI Z170 Gaming M3 motherboard and an i7-6700K CPU and 240GB SP60 SSD. The heat spreaders were thick, heavy, sturdy, and not very tall which helps out a lot. I tested this RAM with the default JEDEC timings, which I don't recommend anyone use, and then tested it with XMP enabled. The XMP speeds were around 15% faster across the board and XMP is the proper way to configure high end RAM so those are the only speeds I will post in this review. 3411 Memory Mark speed 30,418 MB/sec read speed 15,948 MB/sec write speed 19.5 nanoseconds latency Those speeds beat known scores for other similar DDR4 RAM kits. Given those performance numbers, the price on this RAM kit is a very good deal!
Cons: Trying to configure this RAM properly was a bit strange. It was straightforward but misleading and confusing and that's never a good thing. I had very inconsistent problems with the A00 verson of my BIOS on my motherboard but flashing to A20 cleared it right up so I'll only post about my complaints with the latest version. The entire problem was caused by the fact that this RAM is allegedly 3000MHz RAM but 3000MHz isn't an actual operating speed for DDR4. The steps are 2926 and 3059. To get to 3000 on the dot, it had to do some strange things. By default most motherboards will leave the RAM at the highest JEDEC table settings which in this case was 2133MHz 15-15-15-36 timing at 1.20 Volts. Once I turned on XMP, it changed my CPU Bclck (so basically the FSB) on the entire board to 102.31. It suggested this was because the RAM speed was calculated by 22x100x1.33 which would only be 2926 MHz. Since the XMP spec wants 3000MHz, it simply changed my motherboard's FSB to be 102.31 instead which resulted in 3000. The timings matched the listed specs though at 15-17-17-35 at 1.35 volts. Everything worked great and the RAM reported running at 3000MHz in Windows but overclocking your FSB can cause instability and problems with other devices like your graphics card, not to mention making your CPU run a little bit hotter and at a higher frequency than it was designed for. A 2.31% overclock isn't much but it's still overclocking and still may cause problems immediately or over time. For a set of RAM to have to do this just to attain its normal speed can only be what I'd call dangerous and stupid. Luckily on my motherboard I could turn XMP on then override the change to my FSB and set it back to 100. It lowered the RAM speed down to 2926MHz but the performance tests were so close, I'd prefer stability and safety over that tiny speed difference. If it really bothers you, my motherboard at least let me change it to 23x100x1.33 speed which resulted in 3059MHz RAM speed while leaving the FSB at 100. Overall this small annoyance was due to math and exact clock speeds, etc and makes very little difference but it certainly was annoying and wasted a little bit of my time. I had to take 1 egg off the rating though because RAM that alters your FSB just by turning XMP on, assuming my motherboard wasn't at fault for doing that, is completely unacceptable, though you can override it.
Overall Review: All things considered, this RAM tested at extremely fast speeds! Number ratings are just theoretical so if you look solely at the actual real world RAM speed that this kit tested it, it's very fast, even for DDR4.
Pros: *16gb of ram *very fast *Corsair is the best regarding issues with products, and getting them replaced fast so you can get your computer back up and running. *Excellent quality, and very stable *DDR4 operates at a lower voltage then previous memory. DDR4 runs at 1.2 volts, down from 1.5. not much of a difference, and it's really not for your typical home PC. Most Haswell-E desktop systems (where you'll most often see DDR4 in use) will operate somewhere in the 300W to 1200W range. The voltage difference for those numbers might account for a 15W savings over DDR3—not a lot for a home user. But for server farms and other large-scale computer architectures, where you could have hundreds of systems running thousands of DDR4 modules, that 15W difference adds up. Another big difference between older memory, and DDR4 is speed. Older memory specifications started at 800 MT/s (or Millions of Transfers per second) and some went as high as 2133. DDR4, meanwhile, starts at 2133 MHz. The increased speed means an overall increase in bandwidth.
Cons: none
Pros: Works as advertised, running at 3000mhz on my Gigabyte Gaming 6 motherboard
Cons: none
Overall Review: Those people experiencing issues with the XMP profile need to update the BIOS on their motherboards. I couldn't get it to post at 3000mhz either until I update my BIOS version. That is a motherboard issue, not a RAM issue, don't discount the RAM for the motherboard faulting. Corsair makes great RAM planning to buy more in the future.
Pros: Runs at stock speeds with no issue [1500 MHz (DDR4 3000) / 15-17-17-35 / 1.35V]. Works with or without XMP enabled. Low profile. Stable. Good value.
Cons: None
Overall Review: Those reporting issues running stock speeds either have an out of date BIOS or failed to configure their DDR timings / voltage correctly.
Pros: Easy to set at 3000 with XMP profile. Same ram as 3200 model, just loosen the timing to 16-18-18-18-37 @1.35 volts
Cons: None
Overall Review: Recommend for RYZEN CPU and ASUS board.
Pros: There's a reason for this RAM's popularity: It works. Even though this is only rated at 3000, it runs at 3200 no problem (MSI B350 Gaming Pro Carbon + Ryzen 7 1700).
Cons: None functionally. I suppose you could complain it doesn't light up or anything, but is that really a con?

Pros: + Corsair is a great company that backs their products with vigor. Customer service and RMA support is always fast and courteous. They're flexible in their rules if your requests are reasonable. Basically, Corsair is one of the better companies out there in regards to supporting their customers. + Low profile heatsink allows virtually every CPU cooler to work without conflict. + Good average timings and voltage. + XMP 2.0 works just fine IF! your CPU can properly handle the settings. XMP 2.0 isn't magic. You need a CPU and Motherboard that can handle the way it sets up the memory. When in doubt, contact Corsair or your Motherboard manufacturer before purchase. + Build quality and quality control seem to be above average. I don't see any widespread complaints or problems with this line of memory from Corsair. This is good and stable memory. + The biggest advantage for DDR4 memory as of this review is simply capacity. You get a lot more per DIMM and overall system memory is a lot easier to achieve. Since having several tabs open in browsers can literally take up 4-8GBs of space, there isn't such a thing as too much memory these days for power users. Games are also slowly starting to consider 16GB base minimum configurations. So, it's not a bad time to switch platforms.
Cons: - Technically it's some of the slower memory of its class and it doesn't overclock well (it works wonderfully stable for overclocking your CPU but the memory itself is very tight in tolerance - don't expect it to go beyond the XMP profile). I do mean technically in the strongest sense. We're talking negligible differences and in the real world a fraction of a frame per second in gaming. Fractions of a percent in other applications and synthetics. Truly negligible in the real world. As such I'm not going to even bother posting numbers because less than 1% of a difference in the real world is meaningless for mid-grade consumer memory, and I feel it would only serve to mislead and confuse. However, if you're looking for the best of the best, or best technical performance for value, you won't find it in a midgrade budget line of memory here. - The real world difference in gaming of speeds with DDR4 from 2333 to 4000 is 1-3 FPS with an integrated GPU and .5-1 FPS with a dedicated GPU. Basically, raw speed doesn't matter as much as it did with DDR3, at least right now on Intel. I'd suggest you get whatever memory has tighter timings or just what's the best bargain under current platforms.
Overall Review: These days buying memory couldn't be easier and configuring them is also extremely easy if you have a motherboard that supports XMP and almost all do these days. Just don't go expecting to get "top of the line" performance out of memory when you use the lowest binned CPU and motherboards. More importantly, as of today, you'd need very exotic situations, such as professional movie editing, to even care about the settings on DDR4 memory. The real world difference in gaming is absolutely negligible so don't get hung up on getting the highest speeds and the tightest timings. They just don't matter like they used to, certainly not with first generation DDR4 memory. Ultimately with memory if you're a novice or if this is your first time building your computer you want a company that backs their products and responds to you in a timely manner. I often get responses from Corsair the same day and never longer than 24 hours. I'm not a Corsair fanboy by any means, but after reviewing their products for a while now I can say their company is one of the more friendly, helpful and timely ones on the customer service side of things. Considering that support is basically the most important thing for memory these days, that's why I'm focusing on it.
