Description

Vengeance LPX memory is designed for high-performance overclocking. The heat spreader is made of pure aluminium for faster heat dissipation, and the eight- layer PCB helps manage heat and provides superior overclocking headroom. Each IC is individually screened for performance potential. The DDR4 form factor is optimized for the latest Intel X99 and 100 Series motherboards and offers higher frequencies, greater bandwidth, and lower power consumption than DDR3 modules. Vengeance LPX DDR4 modules are compatibility-tested across X99 and 100 Series motherboards for reliably fast performance. There’s XMP 2.0 support for trouble-free automatic overclocking. And, they’re available in multiple colours to match your motherboard, your components, or just your style. Compatibility : Intel 100 Series,Intel 200 Series,Intel 300 Series,Intel X99,Intel X299,AMD 300 Series, AMD 400 Series

    • Works great and no issues with it for my build
Color: Black Size: 32GB Kit (2x16GB) Style: 3000Mhz CL15
I will go into in-depth detail on any item since other popular reviews have given excellent information, so in quick summary: My Build (all components work flawlessly): 1. Zalman ATX Mid Tower Case R1 (Nice looking case, provides room for everything, adequate cooling and allows good cable management). 2. ASUS ROG STRIX Z370-H GAMING LGA1151 DDR4 HDMI DVI M.2 Z370 ATX Motherboard with Gigabit LAN and USB 3.1 for 8th Generation Intel Core Processors (Great expandability and room for future upgrades, enough USB ports for most applications). 3. EVGA GeForce GTX 1070 Ti GAMING, 8GB GDDR5, EVGA OCX Scanner OC, White LED, DX12OSD Support (PXOC) Graphics Card 08G-P4-5670-KR (Great balance of price and performance). 4. Intel Core i7-8700 Desktop Processor 6 Cores up to 4.6GHz Turbo LGA1151 300 Series 65W BX80684i78700 (Came with a thermal solution (fan) but I used the Cooler Master - see below). 5. 2 of Crucial MX500 500GB 3D NAND SATA 2.5 Inch Internal SSD - CT500MX500SSD1(Z) (Man this is fast, Win10 boots in about 5/6 secs. and programs open fast as well). 6. Crucial MX500 500GB 3D NAND SATA M.2 Type 2280SS Internal SSD - CT500MX500SSD4 7. CORSAIR TX Series TX850M 850W 80+ Gold Modular Power Supply (Adequate power supply for into the future and has ample connectors). 8. Corsair LPX 32GB DRAM 3000MHz C15 Memory Kit for DDR4 Systems (Adequate for my application for work and gaming) 9. Cooler Master Hyper RR-212E-20PK-R2 LED CPU Cooler with PWM Fan, Four Direct Contact Heat Pipes (Instructions are poor, system builders with experience will have no problem, first timers will eventually figure it out. Comes with all you need including thermal paste). 10. ASUS MX239H 23-Inch, Full HD 1920x1080 IPS, Audio by Bang & Olufsen ICEpower HDMI VGA Frameless Monitor (Really nice monitor for the price though those heavy gamers will want something far superior. Built in Audio is good enough for You Tube and regular use, but I personally find its not so good for Netflix, look at some decent speakers based on your needs). 11. Sabrent 74-In-1 3.5" Internal Flash Media Card Reader/writer with USB Port , Black (CR-USNT) (For the cost and convince you can’t go wrong). 12. Asus DRW-24B1ST-KIT 24x Internal DVD Burner + Nero 12 Essentials Burning Software + Sata Cable Kit (Obsolete in some ways but good to have at times as some persons still give work items on CD). 13. Backlit Gaming Mouse, Gaming Keyboard, Large Gaming Mouse Pad, PC Computer Gaming Headset with Microphone Combo, S101-BA Redragon RGB LED Backlit 104 Key Gaming Keyboard with Wrist Rest (No issues at all, good feel and responsiveness and mouse drivers are available on the website. The headset sounds good). ... show more

    • Good Timings, Impeccable Service, Amazing Product
Color: Black Size: 32GB Kit (4x8GB) Style: 2666Mhz
I've turned into the kind of dad that looks over his power bill and watches the thermostat like a hawk, so after a few painful power bills in a row I finally retired my first-gen socket 1366 Intel Core i7 system (the processor used over 250 watts when overclocked!) to a new and more efficient Skylake system. It kind of hurt to do since I had no performance problems even six years after I built it, but it was probably time. Anyways, this kit was the best price for 4x8GB DDR4 memory I saw on Amazon at the time of purchase, and since I've had to deal with Corsair's excellent support in the past I generally lean toward buying their products. Their warranty, in my opinion, is the best in the business -- most recently they replaced the 6x2GB triple channel kit from that 1366 PC more than 6 years after I bought it, no hassle and no cost on my end. As of late October the C15 kit (also 2666MHz) is listed for just $10 more than this one, so it may be the better buy right now. When I purchased this kit, the C15 version was about $50 more and I didn't want to stretch my budget any further since I sprang for the i7 over the i5. I am using this memory in a ASUS Z170-A socket 1151 motherboard. An earlier review said the rated speed/timings didn't work on an X99-based motherboard, which may be the case, but I can verify that this kit works as advertised on my particular system. All modules were immediately recognized on POST and all I had to do was set the timings (16-18-18-35), the speed (2666MHz), and the voltage (1.2v) in the BIOS and I was done. The only negative, and it's a stretch, is that the suggested timings were not printed anywhere on the box or individual modules, nor was there a slip of paper with that information in the box -- I don't know if my package had been tampered with or something, but that is basic information that needs to be included with the product. This is just a minor gripe, really, but I'm the kinda old-school PC guy that builds his systems out of the case on a static-free workbench, far away from my router, so I ended up having to look up the timings on my phone. I could have let them run at the default values (MB set them to 15-15-15-36 @ 2133MHz) and set the timings later, but I don't think I should have to go online to get that information. All in all, the kit works at the advertised speed/timings with no hassle and have the added bonus of Corsair's warranty/support. I'm confident that I won't have to buy another kit until it comes time for me to build a new PC -- which hopefully isn't for another six years! I'm sure there is more overhead in these modules for overclockers who want to get every last drop of performance, but I haven't had the time or energy to sit down and focus on that -- maybe I'll play around with it over the Thanksgiving holiday as an excuse to get away from the in-laws. If so, I'll report back with whatever timings give me stable performance. ... show more

    • Worked Perfectly on Asus X99-A
Color: Black Size: 32GB Kit (4x8GB) Style: 3200MHz
Upgraded a ten-year-old Asus X99-A motherboard from 16GiB DDR4-2400 to this kit of 32GiB DDR4-3200. Given the age of the motherboard, having been released near the dawn of DDR4, I was concerned it might not be able to handle the higher clock speed. But a few small tweaks in the BIOS, and the system booted into the new RAMs and completed four passes of MemTest86 without issue. I even got an almost 20% memory bandwidth boost as measured by `stressapptest`. Perfect outcome; no notes. ... show more

    • Excellent value!
Color: Black Size: 32GB Kit (2x16GB) Style: 2666MHz
Excellent value. Quality seems impressive. Everything fit and worked perfectly. Upgraded from 12 GB (one 8 GB and one 4 Gb) to 32 GB (2 16 GB). Took less than 10 minutes start to finish. Made a noticeable difference in video editing.
