Ballistix Tactical Tracer 4GB DDR3 1866 (PC3 14900) Desktop Memory (with Orange/Blue Light) Model BLT4G3D1869DT2TXOB

Pros: Look up a Youtube video of these bad boys. They make any case look 10 times more awesome. it's just...I don't even know what to say. It's amazing that something so simple gets me so excited, but it totally does. I would recommend these on ANY computer with a window, or holes, or any way to see these. They're amazing.

Cons: For some reason they defaulted to 1333 on my board, and while the would post at 1866 without issue, I couldn't overclock beyond that without getting error, even with relaxed timings. I wish I could pull 2133 out of it, but I can't hold it against them if they don't pull it off. So I won't.

Overall Review: The speed at which the lights flicker is based off of the CPU load at any given time, and because of that, it actually makes diagnosing the PC much, much easier. It used to take me upwards of a minute to five minutes to completely be sure whether my computer was just loading something very large, and needed some time to work, or if it just froze entirely. There's a specific speed at which the lights will move if it's frozen, and I know immediately. On the other hand, if the screen stops responding, but the lights keep moving at the same speed or go faster, I know that it's just doing something that's going to take a little time. it's made things like overclocking and installing certain drivers and firmware a bit less arduous.

Pros: 2200+ 9-9-9 1.65V or less fully stable on the three kits I have. Will also do 2050+ 8-8-8 fully stable. Have gotten them up to 2300Mhz 9-9-9 with 1.72V.

Cons: None, other then it doesnt scale up any higher with 10-10-10 or looser timings.

Overall Review: This ram (and all of the newer Crucial kits rated 1.5V) are using Micron D9PFJ ICs. There are other 4GB dimms that will clock higher, but with much looser timings. Ordering my forth kit.

Pros: Only bought 1 to try out light mod. Cant complain, it does look great when there is heavy activity. Not sure if I would want all 4 banks lit up however as it can get bright

Cons: Sensitivity of brightness is high. If you don't set it to the brightest setting, it doesn't look that great, but it is a little overpowering at the highest setting, so its a trade off

Overall Review: Running at 1680 since the rest of my ram is 1600, so I can't comment on the speed difference which is probably negligible between 1866 and 1600. That being said, for the 2-3 more in cost why not get the faster ram?

Pros: Works Perfect in my new Asrock z77 OC Formula. The amazing thing is this ram will run completely stable at 2200 MHz with timings of 10-10-10-28 at stock voltage. I could not be happier.

Cons: None at all.

Overall Review: At 2200 MHz the price performance ratio is off the freakin chart.

Pros: Not only is it decent speed ram but the lights are the cherry on top. definitely added that wow factor to my build. Looks great in a HAF-X!

Cons: None

Pros: I saw a review from Jonathon C. where he could not adjust the LED colors. You have to download the Ballistix MOD Utility to makes changes to color and LED patterns.

Cons: None

Pros: All four work perfect in my ASUS Maximus V Formula, it just looks so beautiful on the mobo, but you do have to go into the Bios and change it to 1866 and timing if have to,

Cons: None

Overall Review: I'm so glade I went with crucIal Ballistix Tactical Tracers!

Pros: 1866MHZ LED's ARE SUPER BRIGHT!!! FAST!!! 34.925mm height wise.

Cons: NONE!!!

Overall Review: Works great with my MSI FM2-A75MA-E35 motherboard. You Have to turn on Intel XMP profile in the bios to get 1866MHZ. No biggy, motherboard auto detects and sets speeds. Get this for your AMD APU!!!
