Pros: ok first off i dont have this set i have 2 of the 2x2gb sets of the 1600mhz with the SAME blue and orange like these......memory is great NEVER had any problems with it running as memory at its speed......overclocks nice...... MY PROBLEM IS WITH THE ONLY REASON YOU WILL BUY THEM!!!!!! keep reading......all of it

Cons: 2 years of running GREAT with them set on blue for both the bottom and top sets of lights.....not even set all the way to high because they are VERY bright..... i now have one stick with BOTH the blue and orange going at the same time across the WHOLE top row of lights.....i now have one stick of purplish pink with 3 sticks of blue......i dont want orange i got the set for BLUE......still bet 5 bucks the guy that made them was a gators fan!!! because who makes orange led fans??? .......going to call crucial on monday and see what they can do.......its turkey day and the nepfews were laughing at me because of the cool change i did not see until today

Other Thoughts: i all so must add im not a normal user......i have over 2500 hours on these sticks in the 2 years i have had them......never had the temp widgit in the crucial software say any of the sticks ever got over 92f for the MAX temp EVER......most users my upgrade their systems before they put 2500 hours on these.....ALL SO MUST ADD my set is NO LONGER MADE........BUT and its a BIG but.....they are still using the SAME LEDS on the new sticks as the old ones.....a friend got the same set list HERE and i was the one that built his rigs......i put the 2 side by side wanting to what they changed because when i got mine they were on close out for 16 bucks for a set of 2x2gb(8gb of 1600mhz for 32 bucks do that now!!).....most people in the post for mine said they did not work with intel boards past the 59 series that is why they cleared them out......SAME LEDS ON THESE STICKS AS MINE they just changed the memory on the board....i cant believe they are 104 for 8gb but they are faster then my set

Pros: unlocked all 4 and running 3.6 with memory at 1600mhz for 3 years now......still can not get past a 80% load in ANY game...including metro last light......CM 212 cpu cooler never gets over 135f......it is still over min spec needed for even the most demanding game every made.....it and a 680 4gb get me over 60 frames a second at 1080p

Cons: NONE even as a dual core it is still a really good CPU

Other Thoughts: i have this on a M5A97 asus motherboard....even being almost 5 years old it still runs EVERY game....it will run even big cards like a gtx 680 4gb with out really bottle necking it as long as you over a 8 series motherboard.....
