SAMSUNG 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model MV-3V4G3D/US

Pros: Inexpensive

Cons: None yet.

Other Thoughts: Got it 4 months ago. No issues at all.

Pros: Fast Ram I got this running 2000MHz at 9-9-9-27 1 timing 1.5 volts from 1600 at 11-11-11-28 1.3 volts (witch supports both 1.3-1.5 because it's 30nm ram) with no issues

Cons: Extremely hard to find, almost impossible

Other Thoughts: Running 3770k @ 4.8GHz stable under prime95 on MSI Z77 MPower Board with MSI 660ti PE and Corsair TX850 PSU with Zalman enclosed water cooling

Pros: - Overclocks like no other
- Tight timings
- Low voltage
- SIMM-like profile, fits inside the DIMM retention tabs!
- Runs very cool

Cons: - Cannot get 16GB kit for $60 anymore :(

Other Thoughts: 4 x 4GB were installed in a Maximus V Gene with a 3770K.
Easily reached 2133MHz 10-11-11-26-1T @ 1.475v (VCCSA/VCCIO/PLL all default). Did not need to overclock or adjust any other settings in the BIOS, just set the voltage, speed and primary timings. I was able to boot at 2400MHz and run benchmarks, but didn't feel like using it daily with PLL Overvolt applied.
For the money these beat any 2133-2400MHz rated kits selling for hundreds more.

Pros: Low profile. Low voltage. Low power consumption. Great OC ability. I'm running these at 1866MHz with 9-9-9-24 primary timings. Great price. No need for fancy memory heat sinks or fans.

Cons: I can't seem to get these to work at 2133MHz or higher. It seems as though 2000MHz is the highest I can get. I suspect this is because my MB is limiting me, so it is probably no fault of the memory.

Other Thoughts: Samsung is a great company. Every Samsung product I have owned has been great. Samsung, if you are reading this, thank you for creating great products!

Pros: Awesome RAM, extremely low profile, Samsung chips on a Samsung board, and they overclock really easily.
Don't let the advertised timings fool you, I can run this RAM on my old Phenom platform at 1600Mhz 7-8-7-21-1T, with an Intel build you can push that way higher.

Cons: They don't sell 8GB DIMMs... ?

Other Thoughts: Seriously the best overclocking RAM available, and it's cheaper than a lot of the other 1600Mhz kits, if only it wasn't out of stock all the time.

Pros: Best ram I have ever buy.
I got this ram to upgrade my "core i7 920" CPU setup on "ASUS P6T DELUXE" motherboard. this setup was designed for 1.5v ram yet this Samsung ram have 1.5v mode that won't have problem working on this platform.

Cons: For some reason my old ram at 1.5v was rung 1700mhz with default settings for the CPU. This need some odd setting on the CPU memory controller voltage to work pass 1400mhz.

Other Thoughts: Am guessing my older ram was optimized for "Core I7 920" and this are better for the new chip-set like the Ivy bridge. Still I manage to have 24gb of ram running at 1400mhz.
I have a stick easily ruining at 1700 mhz OC on another newer machine so I know it is a limitation of the i7-920.

Pros: Low profile
Runs cool
Overclocks unbelievably
Runs at lower timings than advertised

There is a reason this is sold out all the time. Don't be fooled by big heat spreaders and flashing lights. This is the best RAM on the market for anything close to this price.

Cons: It works so well I cried.

Pros: Overclocked to 2133, rock solid mprime all day. Couldn't ask for more.

Cons: None

Pros: Tiny (can fit with the biggest heatsinks out there)
Black (this matters to me since everything inside my computer is either black or navy blue)
Overclocks like a beast

Cons: Absolutely none

Other Thoughts: Got this at 2133, with 10-10-10-27-2 timings, and stock 1.35 with relative ease. I didn't even know about this ram until someone criticized my previous choice for ram (it was cheap g.skill ram) and suggested this instead. Glad I bought it when I did because this ram seems to be very popular now and it continues to raise in price compared to when I got mine for about 36 bucks. :D

Pros: Why buy other companies modules when Samsung is producing the memory for them? Love the low profile and low heat footprint!

Cons: Why the EFF can't newegg keep these in stock? Are they really selling them that fast? So annoying!
