CorsairCMZ4GX3M1A1600C9 Vengeance 4GB (1x4GB) DDR3 1600 MHz (PC3 12800) Desktop Memory 1.5V

Originally was going to go with the 24GB option @ 1066Mhz but saw that option and couldn't pass it up. So glad I did! This memory is fast and makes my computer function so much better @ 1666Mhz. If you have an older PC like I do and want to upgrade the memory, this is a killer deal. Highly recommend this product. Very easy to install and it just plain works.

These are great little sticks of memory. I ordered 4 of the 4GB sticks for my home machine and they work great. Haven't tried OCing them yet but I've heard good things.Only thing to keep in mind is that these things are nearly twice the height off of the motherboard as most standard RAM due to the oversized heat sink. Make sure to check your clearances before ordering.

My wife has an older computer and this RAM stick is working perfectly and she is very happy. Very easy to install and Amazon got it to us faster than their ETA. This is not a good fit for newer games but works great for older ones.

This is solid RAM, but beware the tall heatsinks. These are nonstandard, about twice the height of a normal stick, so you need to be careful that your CPU heatsink does not overhang your RAM slots. If it does, these may not fit.High profile heatsinks, as far as I know, are of minimal added cooling value, and I believe they're a marketing feature more than a technical one. I'd advise looking into low-profile Corsair instead. (or Crucial, or Mushkin.)Despite the silly heatsinks, it's still excellent RAM, so I'll give it four stars.

I had a triple channel kit equaling 12 GB, but then I built a new LGA 1155 pc using dual channel memory; I ordered this to add to my other 3 4gb dimms and it worked perfectly. Dual channel mode worked on first boot, all 16GB recognized. WEI 7.8. I was even able to OC them without any issues. Nice looking too

When installed, is actually a 1333. Product description says it's a 1600, the stick says it's a 1600, but my BIOS says it's a 1333, and I know my motherboard can handle a 1600 because the other stick in it is a 1600 and the BIOS says it's a 1600. Probably would have been great if it was the right speed. But since it's not and I don't want to go through the hassle of returning and replacing, I will just deal with the lowered speeds (as now my other stick is running at 1333), and this company will get a low score review.Edit: may actually be that it defaults to 1333, seems to be running fine at 1600 after setting the BIOS setting from Auto to 1600.

I bought this a couple months ago for my computer, it was low priced so I decided to only get one and see hows it runs. Well it works great so I just placed an order for another so i can get the full 8gb of ram I wanted. for the price and the power this is a must buy!!!

I don't have much to say, but I wasn't able to play everything I had at 60FPS, even though I have a Radeon XFX HD 7850, but after I put this piece of hardware in my game, my performance has improved quite well, and now I can even multitask a lot more. I recommend getting two of these, 8GB will be much more helpful then 4GB (I bought this already having 4GB of G-SKILL RAM)
