Klevv Cras 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 2800 (PC4 22400) Memory Model KM4C8GX4N-2800-16-16-16-36-0

Pros: -Some of the best looking modules out there<br>-VERY high build quality<br>-Memory timings are conservative and can be tightened (CAS 15)<br>-Overclocking potential past DDR4 3000<br>-This is a SK Hynix affiliate memory company not some unknown company (1 of the big 3 memory makers along with Micron and Samsung)

Cons: -Way too expensive, absurdly so<br>-Better performing modules can be purchased for less than half the price of these<br>-Modules very are tall, check your heatsink clearance before buying

Overall Review: Newegg shipped these without any packing material. Because of the their weight, the entire custom fiber box was destroyed and the modules were bouncing around. If I pay near $500 for memory, they should at LEAST have some bubble wrap. Grade F to newegg for lack of packing.<br>I just cannot see who would buy these modules. They are priced to fail in the retail sector. Who in their right mind would purchase a $480 memory kit when a $180 kit performs just as well or better? Even if this were 32GB kit (which I also own in another brand), it would be a stretch. So far very reliable. Have been using these in a Windows 2012R2 server for over 8 months with zero issues.

Pros: -Ram modules and heat spreaders have a Solid industrial build quality -led light strip on top of modules -DDR4 3000mhz @ 16-18-18-36-2T worked as advertised using XMP Profiles -Packaging is nice with a carbon fiber faux texture -XMP profiles for max performance -No issues with Windows 7 or freezing/BSODS

Cons: -EXPENSIVE! -only 16GB -Heat spreaders may cause clearance issues for larger CPU heatsinks

Overall Review: DDR4 is here and along with it comes a hefty price tag. For the price, costing much more than every other component- including an i7 CPU- it doesn't make much sense to upgrade from DDR3 which cost about $400 less. But if you have the cash and are a benchmarker then by all means go for it. But for the average consumer DDR4 is just way too expensive to even be considered.

Pros: Impressive packaging for an impressive looking set of sticks. These things have LEDs that make the sticks glow BTW. Beautiful. Very good performance. Basically exactly what I'd expect letting the motherboard pick up the timing with XMP. Can overclock these but only slightly which for me is not a big deal. Plays nice with Windows 8.1 and Windows 10 preview, SSDs, Nvidia, all Steam Games including Batman Arkham Knight (I think it's very playable at 1080p with no hiccups or visual tearing and every setting maximized) Virtual CP using Hyper-V on 8.1 has no issues and runs very nice. Built-in heat spreaders are nice but not on properly. Read below.

Cons: Price is high but when you want the latest and greatest. Sticks are overly tall in my opinion because (tight on my mobo): There is a decorative acrylic slab doubling the size of the sticks. I think the acrylic looks nice but hinders the air flow through the center of the sticks. The black coating also looks nice but usually painted or powder-coated aluminum does not dissipate heat as well as if it were clean. The disturbing thing I noticed is when I notice one of my sticks not put together properly causing the edge of the screw to stick up. After holding the stick sideways and looking towards the light of my monitor I noticed the heat sinks on 1 side to not sit flush with the chips, hence not properly cooling once over clocked. Leaving timings at the defaults and everything works fine. Any adjustments to above this tolerance resulted in an unstable Windows and gaming experience, but they are dang fast at default. (CPU OC'd just fine leaving the ram to fend for themselves so it's not an issue for you OC freaks, like me)

Overall Review: Using ASRock Fatal1ty X99X Killer LGA 2011-v3 Intel X99 SATA 6Gb/s USB 3.0 ATX Intel Motherboard with Intel i7 CPU with a single EVGA 970 for test. You can take the heat spreaders off if you like and adjust the connections with a very small torque bit. Not sure if this is an issue or not but from an engineering aspect I've noticed the heat spreaders look to be a 6 piece set. The middle strip binds the inner and outer and I'm not sure how well that will dissipate the heat.

Pros: Played with this memory for a few weeks and from a performance standpoint I can't fault it. Outside performance considerations there are a few cons, listed below. For the pros: -Quality chips, all 4 pieces worked out of the box without issue, XMP worked. -Excellent heatspreaders, designed to maximize surface area to dissiipate heat, best I've seen yet. Highly attractive modules, looks like something you would imagine installed in Skynet. : ) They are beautifully dense! -Overclockable beyond the published ratings. Don't hold back playing with these! -Great LED accents along top of modules if Red/Black color schemes are your thing.

Cons: - Very tall sticks, recommend CPU colling be liquid cooled to avoid heatsink bulkiness interfering with space issues. -Price, these are highly expensive when compared to other high performance DDR4. They definitely perform as good as anything else out there but when taking cost into consideration you will pay much more for a few percentage points of improved performance......if that! Some other products can stand to do as good and slightly better, depending on the batch you get, for significantly less money. However, if this memory were produced on the scale of Corsair and G.Skill I think the price would be more comparable. Economies of scale and all that.

Overall Review: I was very fortunate to receive these modules for review considering I was starting a new X99 build. I used these in a Gigabyte Gaming 5 and both products played very well together. Meshed real well with the color scheme on the board as well. If you have the money, this kit will get you performance and proper looks! These sticks have some great OC potential in the right hands, if you're not looking to OC and push things to their limits I would stear clear of these sticks. Clearly, they are for those who love to meddle with tech and wring every bit of juice they can.

Pros: - Incredibly solid build quality. - Down right sexy with the LED lights and acrylic spreader. - Uses Hynix chips, reliable. - Can support overclocking and tighter timings beyond its specified ratings. Rather stable as well. Here are some stable timings I was able to achieve with different data rates. Data Rate: DDR4-3000 Timing: 15-15-15-30 Data Rate: DDR4-2400 Timing: 12-12-12-24 Data Rate: DDR4-2133 Timing: 11-11-11-22

Cons: - Pricy. A similar set from Corsair or even G.Skill is a lot cheaper. - Heat spreaders are a little tall. I doubt anyone will have problems with the height of these sticks of RAM, but something to keep in mind. - Base timings are on the high side in comparison to other sticks.

Overall Review: Got reddot design award for 2015. Essencore is a new name in the RAM department, an Hong Kong company, but the sticks were made in Korea. Fundamentally, I commend Essencore for being new and entering this space. These sticks aren't bad either, but they are fairly overpriced. They do overclock well, but so do the G.Skill or Corsair sticks. I am not sure DDR4 is ready for primetime just yet as it requires a chipset not many consumers have yet.

Pros: Very impressive packaging > arrived encased in an extraordinary compartmentalized case; enclosed memory modules had a science fiction vibe > striking, brushed stainless steel band against a back textured background. Its physical presentation is something to behold; heightening expectations. An insignificant flaw detracted from a nearly perfect presentation; several screws attaching the module's stainless steel collar weren’t properly seated/flush. There’s little doubt we’ve got something special here, turning another page in PC development; DDR4 SDRAM offering improved power efficiency > 20-40% over DDR3; twice the speed of its predecessor DDR3, with faster fault discovery – and - improved data communication with the main board. Despite all that, a case identification badge wasn’t included. Transitioning to these innovations would be quick, if it were as simple as slapping new RAM in an old rig, it isn’t. Taking the leap isn’t going to be cheap or easy; it’ll require new infrastructure to support it > replacing motherboard, CPU + cooling device; things which can be swapped/re-purposed > peripherals, case, power supply, hard drive, optical drive, miscellaneous plug-in boards (Wi-Fi, graphics and etcetera) and operating system. On the other hand, you could start from scratch, there’s no reason too; PCs are modular, designed to be tinkered with. For many, cost will be a deterrent & unjustifiable premature hassle; others will find it as exciting as unwrapping a gift. DDR4’s strengths go way beyond gaming +s; folks, which dealing numbers; words & graphics > large (cross-platform) images, text documents > PDF documents, converting PDF files, creating PDFs, and scientific applications, i.e., radio frequency spectrum analysis. Turning the page from DDR3 SDRAM to DDR4 SDRAM is comparable to the evolution of 802.11n to 802.11ac Wi-Fi a few years back. At that time, the prevailing attitude was 802.11ac it wasn’t ready for prime time; naysayers were wrong; so are folks that are skeptical about DDR4 & this product > they’re on the verge of changing the PC landscape.

Cons: Documentation not included. It’s pricey, so is a Rolls-Royce.

Overall Review: Mentioned, not to detract from the overall quality & performance > the manufacturer has successfully created a beauty contest winner embracing window-dressing and gingerbread, which’ll be unseen in an enclosure, LED light enhancement included. Expensive packaging closely follows suit. From a marketing perspective, aesthetics aren’t as important as price-performance-value. In lieu of the glitz, include a testing report with each module. Simply put, effort spent attempting to create an upscale image is unnecessary; the product doesn’t need it; it speaks for itself. An off-the-shelf DDR4 SDRAM 3000 PC can cost more than two thousand dollars > reason enough to homebrew one. An early adapters hypothetical $970 (memory weighted) scenario > cost-effective CPU ($220) > BX80644E52603V3 (will work with most LGA 2011-3 x99 motherboards, Verify). $250 motherboard + $20 for LGA 2011 cooler - and - (the icing on the cake) Klevv Cras 16GB (4 x 4GB) DDR4 SDRAM 3000 @ $480 >blend with re-purposed parts… Need/want MORE > Enhance swaps! Interesting > the manufacturer Essencore (Hong Kong) was established in 2014 with only 12 employees their house-Brand is “KLEVV.” The Chief Executive Officer holds a Ph.D.; pictures of their (likely outsourced) production facilities in South Korea are impressive. There’s little doubt this is a fresh premium product; evidenced by its Jan, 2015 launch, awards & credentials > purportedly conceived by (some of the) the world's best memory engineers. They’ve got an apparently great product; we need to nurture this new creative in the industry (my contribution, an optimal rating). Competition drivers’ innovation, if you’re in the market for high-end computer memory > support this start-up…

Pros: - The heaviest memory sticks I have ever had or touched before, meaning the manufacture used very high quality parts on these memory sticks - The packaging and build quality is insanely good. The experience of unboxing this memory was reminiscent of the experience one gets when opening a very high end product. - The red stripe lighting on the back of the memory is absolutely brilliant and is by the far the most vibrant and “death-star-control-room” looking I have ever seen. It lights up inside my case and there's another reason why my case has a "window" looking into it again. - This memory can handle anything you can throw at it and then some. While DDR4 still produces about the same performance as DDR3, DDR4 uses less voltage and has a massive ceiling to grow toward as memory densities and clock-speeds increase. - Beautiful styling for the memory as a component. Reeks of modern European minimalism in the best way that is possible. Very creative for Klevv Cras design team on this one. - Four 4GB memory sticks for all four channels! Great option! - Easily overclockable.

Cons: The only con I have is the price - at this point in the life of DDR4, you really are paying for the looks and build quality more than the performance, but these looks really make up for it.

Overall Review: Although DDR3 as it is is more performant than DDR4, that will change over time. If you’re looking for the high-end of high-end and want the capability and future proofing of DDR4 in your system, this is your memory.Especially when there is room for overclocking. The looks are great, it's build solid and feels it too! With other cheaper brands, when you pick up the memory sticks, they may feel flimsy because of the thin aluminum, but with this Klevv Cras memory sticks, you can hold it in your palm and "feel' the difference in materials that was used to make these. The icing on the cake was definitely the red LED's they put on top of the memory sticks. Its bright red and when someone comes over, they always ask, "is that the memory sticks that are glowing red?" Everybody is amazed by them and it gives my PC case a "star wars" feeling to it. I can't explain, you just gotta put it in and see for yourself. Overall, you may find other brands with the same timing a little cheaper for the same 16GB of memory, but with this Klevv Cras 16GB memory sticks, I believe they are worth every cent you spend on it. I had to build a brand new PC to test these and DDR4 memory sticks and found they are buttery smooth when doing such things as daily task such as surfing the net or writing documents, photo editing, video editing and even playing GTA5 on Extreme settings with everything up to the max! Of course, the GPU had a lot to do with it but still... If you want top of the line quality products in your PC and future proof the memory since DDR4 is still relatively new, these memory sticks are the one to get.

Pros: Ultra modern, show them who's boss good looks. LED streamline lighting. Makes you think of a city skyline when looking through the window of your pc box. Creamy smooth performance. Can be pushed far beyond stock timings but not as much as Gskills Ripjaws which are more ferocious performers. XMP 2.0. Great stability due to deft engineered heat spreaders. DDR4 is' last stop' technology before next gen HBM arrives. Perfect for ultra high-end 'dream box' chassis. Show and sizzle come first and foremost. Value for money is the last concern.

Cons: Pricey. Premium pricing is high due to appearance. Perfect for redline users, not so much for bang for buck value connoisseurs.

Overall Review: From the engineering halls of a Korean tech company...
