    My self build PC has been running for 6 weeks with no issues and overall this RAM module was an excellent purchase. It offers great value for money compared to other 4GB modules and as it was only one memory module it provides better scalability for introducing further RAM modules to my system.

    Timings are 9-9-9-24.
    Windows 7 experience score is 5.9 (1x4GB module)

    For those that are interested this is coupled with a Intel i5 2500 1155 CPU, Intel DH67CL Motherboard and powered by a 650w Ocz modular power supply.

    [Please read the Update at the end]

    This 16GB XMS Memory kit (2x8GB memory modules) is very good but the spec is not totally accurate and there should be a disclaimer to this effect. You even see a bold statement "Outrageously fast 1600MHz performance using 16GB of memory" with 1.5V spec shown a few lines below on the same page (unless Amazon corrected this as I have sent them a note pertaining to what I describe here) but this must be qualified.

    Corsair's own website indicates that the 1600Mhz clock rate is achieved at 1.65V which is quite different from the 1.5V indicated here under Product Specifications. If you, like me, use this memory with Intel new technology processors (the latest i5 and i7 CPUs), then the DDR3 memory is controlled by the host processor using an on-chip Memory Controller Hub (MCH). According to Intel's spec, the on-chip MCH was designed to support DDR3-1333/1600MHz memory at 1.5V, and any memory voltage above 1.5V can shorten the life-span of the processor or even damage it. Hence, operating the memory module at 1.65V should be avoided.

    This will not be an issue if an external memory controller is used (which may mean using with older processors), but I haven't looked into such scenarios as they don't apply to me; my interest is with systems using i5-3570K and i7-3770K processors (and many others that share the same Chipset such as the Ivy Bridge chipsets, e.g., Z77).

    I think there should be a disclaimer for customers using this memory kit with Intel processors that use on-chip MCH for memory control (I think all Ivy Bridge and Sandy Bridge microarchitectures, perhaps earlier ones, use the MCH).

    Colour Name: 1600MhzSize Name: 8GB (1x8GB) Verified Purchase
    I've had my PC for over 3 years and recently decided to upgrade the RAM from 8GB to the motherboard's maximum of 16GB. RAM is the only piece of hardware I feel confident enough to mess with. After all, what could be simpler, eh? It just slots in and 'click', right? Err, not quite. I know this might be old news to someone used to fitting hardware, but I'll say it anyway: You MUST make sure the RAM sticks are seated correctly in their slots, AT BOTH ENDS. Even if you do as I did and slot one end in and then rock the other end in until the clip locks it, that doesn't mean it's seated correctly. You still need to check both ends of the stick. In my case the PC just wouldn't boot. The fans whirred but the monitor wouldn't come on and it just didn't make the usual boot noises. I hadn't touched anything else in the PC, just the RAM; it was just as it was when I first bought it. After what seemed like hours trying to get the PC to boot, checking and rechecking everything I could think of, I checked the RAM one last time. It turned out the sticks just needed a little more coaxing into the slots; with one last gentle push on both ends they clicked into place. Then hey presto! The PC booted as normal, and Windows recognised the new RAM. Job done!

    As I write this I've only been using the new RAM for barely two hours and the PC seems normal. On the RAM itself, the sticks say 1600mhz though in the BIOS they seem to be at 1333mhz. I don't see what difference changing these values will do. I'll see how it goes.

    I know to some people fitting RAM is the easiest job in the world, but I just thought I'd share what I went through, in case there are other 'newbies' out there as nervous as I was about fitting RAM. If I can do it, so can you!

    Sehr guter Produkt! Ihr muss doch kaufen!

    I strongly recommend anyone to get this RAM. Ignore those look-at-me Corsair chips with the fins and what have you; they're for kiddies to show off what mom 'n pops got 'em, or just for people who dig that sort of thing.

    This stuff is fast, sleek, and quality RAM. I have four of these in Dual Channel.. 2GB|2GB|2GB|2GB and they perform beautifully.

    I know this is probably really obvious to most of you, but make sure (for those who're new to building) that your motherboard supports DDR3 at 1600MHz, although they will run just fine at 1333MHz, which you'll find them defaulted at. If you have unusual third-party CPU heatsinks, make sure you'll have enough room to fit this RAM, although you likely won't run into any problems. My Arctic Freezr 13 covers a couple of the DIMM ports a bit, on my ASUS 990FX motherboard, but there's really no problem with these DIMMs.

    Personally, I think these DIMMs look awesome, and perform awesomely, so quit hesitating and just grab some! (:

    5/5

    UPDATE:

    Well well well, what can I say? All this time later, and they're still performing "beautifully". :D Epic stuff. The technologically greedy (AKA: Enthusiast? :P) part of me, wishes I had gone with 4GB/4GB/4GB/4GB purely because I can - but being the logical person I am, I know that's just asinine for normal gaming.. 8GB is more than enough. xD ...plus, damn good price!

    Anywho, boys, girls, men, women, and everything inbetween... these DIMMs are damn good quality, IMHO. G'luck!
