G.SKILL Ripjaws Series 16GB (2 x 8GB) 204-Pin DDR3 SO-DIMM DDR3L 2133 (PC3L 17000) Laptop Memory Model F3-2133C11D-16GRSL

Pros: Able to run at a real 17GB+/sec rate. Able to run with low latency on slower systems

Cons: price

Overall Review: This is a very fast RAM. Even on systems that cannot utilize the full 2133 rate, it runs with a lower latency than other RAM. For example on the Intel NUC 2820 it is the only RAM that runs with 7-7-7 timings @ 1333. On the NUC 54250 it runs with 10-10-10 timings @ 1866.

Pros: Running at 2133 with listed timings in an MSI GS60 Pro laptop. High Speed, Low Voltage

Cons: None

Overall Review: Happy to see this running plug and play at the advertised speeds. I was concerned as no one had shown a proven result of the MSI GS60 Pro accepting this high speed of RAM.

Pros: Works with i7-6700HQ, at the rated 2133 speed Benchmarks vs 2x8GB 1600 CL11 Winrar 5.40 x64 MT, +5-12% (the best case real world performance increase) CPU-Z ST, no change CPU-Z MT, no change UserBenchmark CPU, no change UserBenchmark GPU, no change UserBenchmark RAM, +31% BF3 Noshar canals max framerate (empty lobby, standing in same spot), +0-7.8% AIDA64 Mem copy, +28-30% AIDA64 Mem latency, -12% AIDA64 iGPU memory read, +6-47% (not sure why its so inconsistent) AIDA64 iGPU memory write, +25-29% AIDA64 iGPU memory copy, +30-38% AIDA64 iGPU 24 int IOPS, -0 to -8% (performance for the iGPU decreased here. don't know why.) AIDA64 dGPU memory read, +4-8% AIDA64 dGPU memory write, +10-15% AIDA64 dGPU memory copy, no change AIDA64 iGPU 24 int IOPS, no change Overall there is absolutely zero performance benefit for daily use if you have a discrete GPU. Perhaps for winrar/7zip users there will be a time savings of a couple seconds - and probably for gaming there could be an increase in min/avg/max framerates (especially minimums, I tested max fpa only by looking for the highest numbers reached by fraps over the course of a minute or two - very unscientific but remarkably consistent. BF3 went from 185-->196 maxFPS in 720p) I noticed that clocking the CPU higher actually reduces memory performance both on CPU & GPU side - and this gets worse with the faster 2133 RAM vs 1600. Very strange. I don't recommend this unless you are truly desperate for every last 0.00001 ms of performance possible and have no concern about cost.

Cons: x

Overall Review: Benchmarks were performed twice at 2.1GHz & at full speed/turbo for i7-6700HQ, windows 7 x64 GPU used was a gtx960m overclocked +135/+525 I did not measure power consumption, which would be a nice thing to measure.

Pros: hers the deal. it's the best there is. it wakes up in the morning and it pises excellence. its just a big hairy american winning machine.

Cons: heres the deal. nobody can hang with its stuff

Pros: Great memory. I tried this in three different laptops with different CPUs. It always came up as 1065Mz/11 according to the Speccy utility. No problems, just fast. This memory will rise to the occasion as you push it. I was benchmarking with Passmark. It did fine with the i5-3320M but it did better with the i7-4700MQ. With the i7-4900MQ it runs even faster. About a 100-125 point jump for each CPU.

Cons: More expensive, but if you went for the i7-4900 and the Samsung 850 Pro shouldn't you get the fastest memory too.

Overall Review: Lenovo T540p, T440p & T430

Pros: Bought these hoping that they'd be compatible with my Gigabyte P34Gv2 CF2 and they are all the way. They instantly clocked in exactly at the speed as described. So far no problems have risen and they work great. The price is reasonable and the fact that they work at the intended speed is awesome.

Cons: None other than that it might be a little pricey but you get what you pay for.

Pros: This is the only memory I have been able to find that runs 2133MHz @ 1.35v. This is on an ASUS G750JX with a Haswell 4700HQ, so Haswell chipsets DO support 2133MHz SO-DIMMs. The modules run at the advertised timings as well.

Cons: Only con is the price, but as always, you get what you pay for.

Overall Review: Be careful when looking at memory because your motherboard may require 1.35v. A couple of manufacturers advertise their memory as running 1866 or 2133MHz @ 1.35v, BUT they in fact do not. They will operate at 1.35v at lower frequencies but require ~1.5v to hit 2133MHz. I upgraded from 4X4GB Samsungs, to 2X8GB Crucial Ballistixs, to these 2X8GB Ripjaws. 3DMark 11 scores jumped with each successive upgrade.

Pros: Lower power draw and faster memory for the last great user serviceable MacBook Pro!

Cons: Weirdly; while these sticks work with the entry level 2.3GHz MBP; I've only been able to get them to start up once in my 2.7 GHz unit. The 2.7 machine seems to accept 1866 MHz sticks - but not these! For some reason, top Geekbench results for both 2.6 & 2.7 GHz CPUs all seem to sport 1866 MHz RAM; whereas top Geekbench results for the 2.3 GHz CPU do sport 2133 MHz RAM. So this could be an odd architecture thing...
