Works great out of the box on my Asus P6T motherboard.

Corsair XMS3 6GB (3x2GB) DDR3 1600 MHz (PC3 12800) Desktop Memory 1.65V

I had a set of old OCZ rams (3x2GB) installed on my Asus P6T motherboard. A few years back one of them went faulty and doesn't work. So, I figured that I can live with 4GB of ram. Recently, in the past year both OCZ rams started to go faulty. The memory sometimes would read only 2GB and even occasionally the PC would shut down because no memory could be read!

It started to get on my nerves so I decided to buy new rams. After some research I decided to go with Corsair.
They work out of the box and are great. I haven't been so much happy seeing 6GB again! I may get another set next time!

EDIT

I wanted to write this. Its been well over a year now, and the rams work great without any of the previous problems mentioned above.
I wanted to buy another set, but the prices of rams seems to be up for almost a year, compared to when I bought it.

EDIT SEP-2018

So I was able to buy a second set of these rams to as to get the maximum GB capacity the motherboard can handle which is 12GB
The first time I have inserted the rams only 8GB out of the total 12GB was showing up
I removed all of them and installed all once again and all 12GB is now showing up.
There is a very minor but a bit noticeable improvement in performance.
Good purchase.

Great upgrade, boosted performance

Reviewed in the United States on April 10, 2013

Size: 8 GBStyle: 1333 Mhz CL9Verified Purchase

I purchased two of these 8GB packs (4 pieces totaling 16GB) to replace the four 2GB memory modules which shipped with my PC.

Running an Intel Core i7 processor with Windows 7 Home Premium, I knew that despite the specs saying this desktop could support 32GB of RAM, the operating system would only utilize 16GB - thus no need to add more than 16. (TIP: Be sure to read up a bit on 'Max Memory Limits' via a Google search, before adding memory to your PC or laptop.)

Memory shipped in retail Corsair packaging. Easy to install, and all 4 of the memory modules were recognized by my system immediately upon reboot. Already set to run at 1333 MHz, there was nothing to do in the BIOS of my PC. Plug-n-play compatibility and as promised working order.

While the Windows rating on my PC didn't change (it always reads the lowest score as the main score - mine is the video card), the performance boost was noticable when surfing the Web. Different browsers yeilded different results. Surprisingly, IE was super fast, followed by Opera and Firefox. Google Chrome is what I normally use, and it turned out to be the slowest.

Photos and videos open faster, and boot time was reduced slightly. Game play was significantly improved, especially when running other programs like Windows Media Player in the background.

The system runs cool with the new memory and I'm happy I finally pulled the trigger and bought this upgrade. The cost was prohibitive when I bought this system two years ago, but with current prices, it's an easy DIY upgrade that will add to your systems performance and your enjoyment.

Reliable and inexpensive memory modules

Reviewed in the United States on December 27, 2011

Size: 8 GBStyle: 1333 Mhz CL9Verified Purchase

When I upgraded my computer to the Core i7, which requires DDR3 RAMs I had to upgrade the memories too alone with a new compatible motherboard. I end up choosing this PC3-10666 1333MHz DDR3 Memory Kit. I've ordered the first set and then two weeks later, I've decided the computer may perform better with double the memory. I went ahead and ordered a second set which was $16 cheaper. It's relatively inexpensive considering having a total of 16 GB. These relatively cool running memory sticks works extremely well with my new system. In conjunction with my new processor. DDR2 and DDR3 has the same dimension slot with 240 pins but aren't compatible with each other and therefore purposely made with a different position blocking cut-out to prevent insertion on the non-compatible system. DDR3 has a lower voltage requirements then DDR2 and therefore consume less electricity. These memory modules requires only 1 1/2 volts to operate.

I have no problems with both sets and are extremely happy with these memory sticks. I highly recommend this product to anyone.

Works great in my HP Pavilion Elite HPE-337c

Reviewed in the United States on November 3, 2018

Size: 8 GBStyle: 1333 Mhz CL9Verified Purchase

Ordered 2 pairs of DIMM's to upgrade my HP Pavilion Elite HPE-337c from 8GB to 16GB. Only been installed for 5 days now, so can't vouch for reliability, but working perfectly so far, and Crucial has always had a pretty good reputation for quality and reliability. Ordered these after purchasing a less expensive set of 4 DIMM's from a supplier I wasn't familiar with, and getting 3 good DIMM's and 1 bad one. Returned that set and bought this set. The higher cost is worth it to get good quality, and I should have bought this to begin with.
