G.SKILL Ripjaws X Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBXL

Pros: This ram looks great, runs fast, and works without problems. Even though this ram is not listed on the ASUS website as an approved compatible ram piece for the P8Z77-V LK, rest assured, it is very compatible. The board correctly identified it upon initial startup and even got the clock speed correct. This ram will also fit if you have a coolermaster 212 EVO on your CPU. If you want it in the very 1st slot though, you will need to raise the CPU cooler fan up a tiny bit, but that's not a big deal. I am 100% happy with this ram set.

Cons: None.

Pros: Looks great
Works flawlessly
Super fast
Excellent price

Cons: Not really a con but I had to manually change the timings in my BIOS to run at 9-9-9-24

Other Thoughts: Will use G.Skill again in the future. They are my go-to RAM company

Pros: Good Memory
Fast
Does the job well

Cons: None

Other Thoughts: I use this on my gaming rig, never had any issues with it. Does it's job FLAWLESSLY. If you want some good memory and are on a budget, this is the way to go

Pros: Looks great, runs fast, XMP

Cons: None.

Other Thoughts: Speedy RAM. Stays cool. Can't go wrong with GSKILL

Pros: Even tho I did not notice that this RAM was designed for sandybridge untill after ordering. Runs very well in my AMD board. Have not tried to OC yet.

Cons: Cost money.

Other Thoughts: GREAT CHOICE! This will be my brand of choice when i upgrade to either the 8gb or 16gb kits.

Pros: Beautiful heatspreader, matches system, other set works wonderfully

Cons: DOA...ran amuck causing random BSOD's and random reboots...ran memtest 86+, failed on test #3.

Dear Customer

We are sorry to hear the memory did not work properly. This memory kit is above standard, so please make sure to configure settings in BIOS. It is necessary to enable the enhanced performance profile, if your motherboard supports it, otherwise the DRAM Frequency, timings, and Voltage need to be manually input. Once you input the proper settings, the computer should work fast and stable without any crashes. Should you have any questions or issues, please feel free to contact us directly. We are certain you will be pleased with the performance of this memory kit.

Pros: Wicked looking memory, nice big heatspreaders attached to it. Its shiny red. Also have XMP which need to set it in bios.

Cons: None

Other Thoughts: I had bought another G.Skill product in past and never failed me. I recomend G.Skill to anyone anyday.

Pros: Running them at 9-9-9-24 2N with no problems. Heatspreaders looked a little tall but fit fine with my Noctua CPU cooler.

Cons: None.

Other Thoughts: I've always had great success with G.Skill and will continue to use them unless I find a reason otherwise.
