This review is about the CORSAIR Vengeance LPX-16gb RAM 3000 Mhz (C15)These were coupled with an Ryzen 5 2600 and a MSI B450 Tomahawk. It worked greatly and without any problems, was easy to input into the motherboard and came packaged neatly and safely. It also looks good in your system with a black or white setup although it doesn’t come with RGB.This informational review is aimed for new PC builders. Therefore, if you are already knowledgeable in RAM there is no need to continue.1. (C15) refers to CAS Latency, which is how quickly your RAM responds to a command, you really won't see a difference at all between CL15 and CL16 although you will notice C15 is considerably more expensive as it is better in synthetic bench marks but you wouldn’t notice this in real world performance.Therefore get whichever one you want.2. Mhz refers to how fast the RAM performs. The speed of a computer processor, or CPU, is determined by the clock cycle. Computer processors can execute one or more instructions per clock cycle, depending on the type of processor. Therefore the higher Mhz the Ram outputs, the faster the RAM can perform tasks. (3000-3200Mhz is considered the sweet spot for mid-higher end workstation + gaming), any beyond this is overkill for your average needs and unecessary money spent.3. GB refers to Gigabytes: Some computer programs, especially Windows, uses RAM to swap frequently loaded programs back and forth, it makes the computer seem to run faster. Therefore in simple terms, the higher the GB the more tasks your system can perform at once before it starts slowing down your machine.Recap: What you want in your system for your needs1. Higher GB8GB is standard for workstation purposes and light gaming.16 GB recommended/a must for medium to higher end gaming.32 GB is for higher end computers, and unecessary unless you are doing a very heavy work load at once which requires it.(More GB = More tasks your machine can run at once)2. Mhz(3000-3200 is the sweet spot, nothing more is required unless necessary for your use).3. BrandBrands make their ram different. However Corsair is known for its tech, are very reputable and trustworthy, therefore they are a company you can depend on that make good quality products.4. (CAS Latency)Latency won’t be an issue, get which ever one is labelled cheaper as long as it has any of the above I mentioned.Happy building!

Even though my PC is a closed box, solid sides, I still wanted a spalsh of my signature colour inside the white case with predominantly black components! Don't be put off by some of the pictures you see of this that make it look like a flat, dull red. These sticks of RAM are like a sparkly candy-apple red, as shown in some photos of it installed.Other than that, er, yeah, it's RAM. A few things for you to consider thought when buying RAM:1. What will your CPU actually support? A core i7 9700 (like I have) will only take advantage of 2666MHz. You can use faster RAM like this, but the gains for Intel are marginal.2. Faster RAM doesn't necessarily mean better. Aside from capacity,RAM also comes with a couple of other key numbers. Speed (3200MHz in this case) and latency (C16 in this case). You need to consider both, and there is a formula for it (assuming dual channel here):latency/speed*2000 = 16/3200*2000 = 10nanosecondsIf you do the maths, you'll see that 15/3000*2000 also equals 10 nanoseconds. So, you'll often find that faster ram has slightly worse latency, which broadly balances out. So why buy faster if slower can ultimately perform the same on paper? More bandwidth - simple as that. For a given latency, yes, more MHz is better, and you are always better off getting as much bandwidth as you can afford, but, you'll find that high speed and low latency starts to get very expensive very quickly and for marginal gains (read, bragging rights).It also depends on what you are using your PC for as to what to get. For gaming, you aren't going to get much benefit from super-fast RAM and using more than 16GB of it. There's always a performance/benefit curve with PCs and components, and the best PCs are those that use components in good balance.

There isn't much you can say about this stuff really. It does what it's supposed to do. At the moment it's great value for money and is about the best price/performance for intel 7 and 8 series systems.There are other, different frequency RAMS, but offset by worse timing and higher prices so overall tiny performance increases at higher cost. If you really want the next step up, another two percent performance, then you have to increase your spend by 20% or so and buy 3200Mhz CAS 14.Do remember that there is no guarantee that this will work at the advertised settings in your PC. This is not a limitation of the RAM, rather of your PC. The default setting for the RAM is 2133,and every system will run at that speed but the moment you go above that frequency the rest of your system may well fail. To try full speed you need to enable XMP in the BIOS. If that doesn't work then it's down to you to tweak the settings until you find some that works. No guarantees. Series 7 is guaranteed to work at 2133 and series 8 at 2666, but most will work at 3200. 3000 and 3200 are popular and performance difference between them is pretty much unmeasurable so just buy which is cheaper.On XMP I discovered my motherboard was going just a bit high on the voltages so I actually set everything up manually and slightly lowered the voltage. In fact it was 100% happy at 1.3V.

I got the 16gb (2x8) 3000mhz kit as an upgrade, as I was previously on 8GB RAM clocked at 2133mhz when I originally built my PC. Whilst my current mobo doesn't go over 2133mhz (unless in XMP for 2400 I think, I leave it off anyway), the dual channel support is still there. Overall, even though I've only used this new kit for half a day, they are very smooth and much better than the 8gb I was on.Before, when I was playing games such as Battlefront 2 or Black Desert Online, I would suffer huge stuttering when in areas with a lot going on, due to the nature of the games, however I'm able to play them just fine now with the extra 8gb of RAM compared to before, even if I'm not fully utilizing the speeds offered by the sticks.Figured it would better to get these sticks with these speeds, for when I eventually make the jump to Ryzen and upgrade the mobo, to adjust for the higher RAM speeds used by Ryzen and the recent-ish price drops to RAM in general making the purchase more viable.Anyway, before I get derailed too much, great sticks, easy installation, prompt delivery from Amazon. I'd probably reccommend 16gb of RAM, over just 8gb, if you're planning on playing recent games (or VR games) as 8gb just isn't enough anymore.

This is our second PC build, previous build was centered around the i7 and Asus 970 Strix in SLI it was a beast of a PC.So after a few years, a few issues and lack of supporting spares, cheers motherboard manufacturers for constantly changing the pin amount, we have built a new pc based on the ROG B450 F, the AMD 3600x and the 2070 super.The build was simple, the setup easy and installation a doddle. We have used Artic silver for thermal transfer, which reduces temperatures enough to allow use of the stock fan, note.. the supplied fan with the AMD is not the light up as advertised.The windows installation was straight forward and bios was up to date to accept the components we were installing.Visit manufacturer websites for the Gucci software and ensure your drivers are up to date.Now, I’m not one for tech specs but I will say “beast” that is the computing performance, graphical look and output and I mean solid, it looks amazing, is very quiet,(make sure the AMD fan is secure to the stops) and keeps cool. (We have made use of the extra fan ports and some splitters, running about eight cooling fans.All in all a monster PC that cost about £1000, which is not bad.

This RAM stick is lightening fast. Totally brilliant and one of the best in the market for high end gaming. This is for a gaming rig I hooked up for my kids. It was long overdue.I am using a Asus TUF Gaming X570-PLUS motherboard with a AMD Ryzen-5 3600 MHz 6-Core processor with this Corsair Vengeance LPX 16GB DDR4 3200MHz RAM. My graphics card is ASUS Radeon RX 580 8GB Dual-Fan OC Edition GDDR5. The PSU is Corsair RM650. I'm using two hard disks in this. The booting is Western Digital WD Blue SSD 250 GB SATA III and the bulk storage is a standard 1 TB Seagate Baracuda as the secondary. All this is housed in a Corsair Carbide Series CC-9011050-WW cabinet.I'm using Samsung 27 inch Curved LED Backlit Computer Monitor and Redgear Pro Series Wired Gamepad. The keyboard mouse combo is Redgear Manta MT21 Gaming Keyboard. The sound is from F&D F-203G 2.1 Channel Multimedia Speakers System. Everything is bought here on Amazon within days of each other and it is perfectly matched.I recommend this RAM and whole setup to anyone interested in building a top-of-the-line gaming computer that will not be outdated anytime soon.Highly recommended.

the start of 2018 was something special for me. i had acquired enough money to finally get into building my own rig. and going from a i3 540 @ 3.02GHz | 4GB of ram and a GT640. this was the biggest upgrade to date and with the arrival of 8th gen intel processors the i5 seemed like a good entry point.my build was originally meant to beintel i5 8600k8GB RAMNvidia GT780 (gifted by caring community member)Corsair 750m PSUand just 3 months in with the 8GB of ram 1 stick had failed on me. noticing that i was caping out on ram super quick upon start up as well as in games performance had crippled. i might have just got a bad batch or something but no harm overall to the PC.i upgraded 2x8 sticks as ram prices started dropping and inventory was quickly running out. and have had the new sticks for nearing 9 months now. and its all great and dandy.no complaints other than the value for money which at the time for me was quite expensive compared to what its at now. but hey you win some you lose some. either way im happy with how things have turned out!

This RAM is fantastic to supplement your build providing great snappy speed. Take a look at the video for a closer look and how to enable your RAM to run at 3200mhz clock speed. It's perfect for AMD Ryzen CPU currently using this with a Ryzen 5 3600XT on a Aorus Elite B550 Motherboard. It has amazing build quality and consists of an aluminium heat spreader for efficient dissipation of heat.Out of the box it was running around 2100mhz, to enable it to run at it's highest clock speed of 3200mhz you'd need to ensure your motherboard is on the latest BIOS for stability. Once this is has been done enter your BIOS and find either D.O.C.P or XMP (Depending on your motherboard).For this particular motherboard you'd need to enter Tweaker and enabled XMP selecting profile 1. Restart your PC and now your RAM is running at 3200mhz. Easy Peasy.Overall, great RAM that does the job, it's very easy to enable it to run at is highest clock speed. I would highly recommend.

Bought the 64GB kit and simply set the desired speed in the BIOS and it goes with no problem.Expensive but I'll never have to upgrade the RAM which I have done on other systems which actually does work out to be the most expensive option over time.Now, lets have a look at those OC settings...Had to up the voltage to 1.36 as the board was having some random issues at boot time. Stable now. Perhaps the draw on four modules or just electronic tolerances. I'm going to build another with two modules out of interest.Further update - it was, I think, the 2103 BIOS update, looking at the forums it seems to draw down the DRAM voltage. Had a couple of BSOD and sliding up to 1.38 seems to have sorted it.Spent the last few hours running some tests and installing Office etc. Going to run a few video reencodes just so see how she does. A bit quicker to sort out than my trusty P5Q3 deluxe which is happily sitting at 1600mhz with 16GB and a QX9750 at 4.3GHX.

I recently made a massive PC upgrade/overhaul, moving from an FX-8320 and FXA-990 mobo...to a R7 2700X and Gigabyte Aorus X470 Ultra Gaming. With that said, I also had to retire my 32GB HyperX DDR3 1600MHz CL10 RAM. I couldn't downgrade in RAM capacity, and intend to max out my mobo's DIMMs at some point. Judging by the "Verified Purchase", and this review, you can guess what I ultimately went with.Out of the box, you'll expect, and might be confused, as to why the RAM is running at 2133MHz. This is pretty standard. So you'll definitely need to go into your UEFI BIOS and select "XMP Profile 1" to ensure it's running at its best. It might vary on how/where you need to enable that.But I've decided to attach some images from my BIOS.Since I don't have other DDR4 to compare this to, I can't offer benchmarks. All in all, it's low profile, and even if it isn't RGB--it still looks great.

I can boot only using 2133 frequency ,when I hoped to get at LEAST 2400 Mhz thats rated.Before this purchase I used practicaly same RAM Vengeance LPX with same timings and rated 2400 mhz but 2x8 GB.I had no problem using from start,and could even take it to 2800 MHz no problem.This is really a dissapointment for me at the moment,I am trying to get it up at rated speed but no matter what I do in bios at the moment doesnt help...I posted a photo of my "old" ram ,you can see it is essentially same model.If I manage to fix it soon I will change this review,if not I will try to return or exchange for something else at the seller.Edit,after update of my BIOS and setting tRFC timing to 421,memory works just fine,so it was actually my fault for it not booting at 2400MHz.Thanks to seller for fast shipping and delivery,+ technical support to fix my issue :)final rating 10/10

Bought Corsiar standard memory 2600mhz 2 sticks 8gb each so it balanced across the DIMM sockets installed on a MSI x470 motherboard running a ryzen5 processor, MSI GTX 1070 gpu. Installed with no issues put together in under 20 minutes and booted up and windows 10 installed within the hour. Bullet proof ram you can go for faster speeds up to 3600mhz for this motherboard but ££ against speed your not going to notice any benefit unless your a speed geek more interested in measuring speed over playing games or even video editing better adding more sticks …. my opinion of Course. Ensure you check out what RAM your processor can manage before buying bigger ram only to find out that your processor cant use it (wasted money and hours trying to tweak it to get the stated speed out of it),and ensure the motherboard can manage speed too otherwise you will freezing issues.

Writing this review in August 2017 when the price of this ram is £124.99.I bought this ram for £56.99 back on 24th of March 2016.Absolute steal for £56.99, but you won't get this ram for that price in late 2017 or for a long time due to worldwide DDR4 shortages.At the time it was a great buy, but This ram has some weird issues with the Asus Z170 Pro gaming board and playing the game called Runescape, weird but me and 3 other users were stumped and found out we all had the same motherboard and ram combo that was causing the issue and changing ram was enough, so if you have a Z170 pro gaming from Asus and this ram, you might... maybe run into issues with Runescape in NXT mode.Other than that,this ram needs to be overclocked with the XMP profiles in bios to run at it's advertised 2400Mhz speed, I was confused at first when it was running at 1666Mhz

I had absolutely no idea that there were so many different types of Ram these days. This was my third attempt as I was having difficulty in reading the labels on my pc's original ram and the paperwork that came with the pc was "generic" not specific to my setup, so I wasn't sure that even Corsair's amazing website help was right. Amazon were absolutely brilliant in exchanging each wrong purchase. I was relieved when I opened the package and it looked as if it would fit. Opened up my pc (yet again) placed it where it should go - in it popped. I put my pc back together, turned it on. I noticed the difference immediately. Before fitting this I had time to turn on the monitor and either the keyboard or mouse - not this time.I checked the settings and I had doubled my ram - at last! PC still working perfectly and very fast.

Great ram to pair with a current ryzen build, I didn't have to manually tweak the MHz with my motherboard, I just had to select DOCP profile 1 and it is nice and stable. The ram gives a noticeable improvement for my ryzen 5 2600x build, there is a bit of a boost in fps and smoothness , little less input lag occurrences across the games I have been playing as well.I picked two of these up separately and both are working flawlessly with no issues in my current sff build. The heatshroud I'm sure is benefiting these in the compact case.C16 and in my experience great ryzen compatibility have made this the perfect choice for me at the moment - 3000mhz is doing the job.Id advise you to be sure that you have your ram speed set correctly in the bios to be sure you get the most out of this stick or just enable d.o.c.p there.
