Kingston Technology HyperX Predator 32 GB RAM Kit, 4 x 8 GB 3000MHz DDR4 Non-ECC CL15 DIMM XMP PC4-19200 HX430C15PBK4/32

Hello everyone!I don't know if the press release has not the tech news sites yet but I have some inside sources and, from my own testing/experience with the new program, that Kingston is about to publicly announce a program it's been implementing in house secretly for the past six month or more! This is some really exciting stuff that has been translating into reduced production time and, subsequently costs, for Kingston which will translate into lower costs for all of us consumers! Kingston now stands to be the value leader in the desktop memory market as these changes are nothing short of game changing.Alright, I know want, no need to know the details, of what's going on inside Kingstons in house. Here we go: the project has been operating for at least six month or longer under the project code named "Couper les coins ronds." The goal of the project has been a very simple one for Kingston - to utilize a combination of analytics, consultants, engineers, independent consultants to evaluate all aspects of the supply line from the start raw materials to the product up and running in the systems of the end user. It has been a daunting task which has encompassed thousands of man hours. The end result was the ability to increase the production of memory coming off our manufacturing lines while simultaneously reducing the time it takes to produce the memory and get it out for shipping (the exact data is classified as it is proprietary so I can't divulge the exact numbers).I can however tell you the optimizations Kingston has implemented, having experienced them first hand as a consumer and, again, having access to numerous inside sources. Kingston's new optimization's rely on a few factors which directly impact all of us consumers. The first is that Kingston has all but cut out through and/or extensive quality control testing of their chips post production. They no longer are running as extensive of a battery of tests and possibly sampling less chips from production runs.These cut backs allow them to produce more chips, sell more chips and get more chips out into the hands of the consumer - with little regard for for the impact these defective chips will have on their work, lives or the time consumed in narrowing down that the chip itself is the root of the issue. The exact numbers of "defective chips", extensiveness of the testing done on sampled chip, the degree of random sampling and/or the failure/bad chip rate is all proprietary information but a search on your own will allow you to reach your own speculative conclusions.Now in the past defective memory might have slipped past the consumer or not caused noticible issues, this is more often then not, no longer the case. However, Kingston still makes their money off the sales to the supplier and collect interest on the bulk sale to the supplier. Many consumers may not be savvy enough to diagnose that the memory itself is defective and, therefore, never return the memory to the retailer, thus Kimgston still keeps the sale. Or the user will blame the issue on something else or just simply give up, Kingston gets away without issue.Lastly, and this is both a very real possibility but speculative one which builds on them completely cutting corners on cutting quality control, they may be purchasing defective or damaged silicon from the foundry which makes its memory chips. This is pure speculation but it would fall in line with all the behavior exhibited by the company.As for my adventure with this sub-par, cut corner, defective silicon. I purchased the components for a new system last Monday, built it, started having random lock ups. I started all the diagnosis across the board. CPU passed, no overclocking, memory even under clocked, all new components, even tested with some old ones. Then tests the memory with Windows memory diagnostic, indicated errors and issues and to contact the manufacturer. Then I ran good old reliable memtest, failure after failure after failure. I tried the memory in another system and repeated with the same results.Now, I have to replace this garbage memory and I have lost two or three days of troubleshooting which I should never have had to do if the vendor had done their job in the first place. I cannot, nor will I ever, recommend this or any Kingston product to anyone ever throughout the remainder of my computer career. I have a new corporate slogan for your Kingston, Garbage in, Garbage Out products.

As part of my new build, I decided to go with the Kingston Hyper X memory. As every has their favorite brands to use when they are building their machine, and I don’t know if I would say favorite or not, but I do tend to go with brands that I had no issues with and have been stable and reliable in the past. I have a set of Hyper X memory in my old computer that is between 7 and 8 years old and works as good as it did when the memory was new. This memory is fast, works well and you can tell is quality built.Overall, this is great memory that is fast, reliable, works as it should and has a lifetime guarantee.5 starsMy build (designed for future upgrade-ability and expandability) is as follow (using Windows 7 Pro, each hardware part, I will review separately)Creative Lab Sound Blaster ZAsus X99 Deluxe MotherboardCooler master Nepton 240M Water coolerCooler Master Cosmo II caseEVGA 04G-P4-2978-KR GTX 970 video cardKingston Hyper X Predator memory DDR4 2400 (16 GB)Samsung EVO 850 SSD Hard drive (main boot drive)Seagate Hybrid hard drive (secondary drive)Intel 5820K CPUCorsair HX850I Platinum certified Power supply

* Not able to Comment on Memory quality directly so gave 3/5Having purchased Kingston products in general and memory in specific they have always made good products not necessarily the best but always reliable and worth the cost. In this case my issue comes in the packaging, They made it "easy open" style plastic. Unfortunately for me it was evidently so easy to open that I only received 2 of 4 memory sticks, with no "seal" on the plastic container. I am rather disappointed with Kingston and amazon, both of which have evidently cheaped out on quality control (in regards to shipping) which when your talking about a 300 dollar product is irritating to say the least. So note to Amazon/Shipper and those receiving the item, when kit of four is clearly listed ensure there are in fact four sticks of memory in the box.

Compatible motherboard and all that, still having some trouble getting the full 3k out of it but its still extremely fast and I think I can get that speed if I dig more into the BIOS. Basically love it and I plan on buying another set just to have 64gb and part out stuff to ramdisks!

Installed and booted ok, but memory failed Prime95 at rated XMP speed of 2800 or even the secondary profile of 2667. Stock 2133 speeds ran fine. Tried on two motherboards (Asus Z170-E and Rampage). Abnormally large and heavy heatsinks (largest and heaviest heatsinks I've ever seen on memory ever for personal (non commercial/business) home computing) made using a Noctua D14 air cooler impossible but H50 water cooler was ok. Plugged in my G.Skill bare 2400 sticks and they ran like a champ on both boards. Looks wise, very attractive memory just disappointed as I've used Kingston memory in the past (currently my laptop is using their HyperX DDR4 2400 and runs perfectly) and it has always performed as described so I will notch this one up as an anomaly.

Received quite a few bad sticks and had to send back and replace. I will say this is the first time I have had these issues but this isn't the first time Kingston has had issues with their flash memory performance.

Great RAM, over clocks well to 3200MHz CL14-14-16 1T with just 1.41V. This RAM should do 3200CL15 with ease! All in all I found this kit to blow away my G.Skill Ripjaws4 3000CL15 kit and highly recommend considering buying this kit.Please see the attached superPI 32M screenshot showing The Kingston HyperX Predator 16GB 2666CL13 at 3200CL14.
