Pros: This memory, running at 1866MHz (XMP), has survived without an error, 8 hours of Prime 95, and 24 hours of two different memory tests. I am running a i7-2600K CPU at 4.8Ghz (Prime 95 stable) on a ASUS P8Z68 Pro Motherboard. The build was almost too easy!!!!

Cons: None so far

Overall Review: This build was my first build in almost four years when I built two machines with QX9650 Extreme CPU's. This build was much easier and faster. I spent a lot of time four years ago getting 2 GB Corsair DDR3 1800MHz (XMP) memory to work (stable). The G.SKILL 1866MHz (XMP) worked right out of the box with zero problems!!

Pros: Fast! My setup is an ASUS P8Z77-V-Deuxe MB, i7-3770K @ 4.6GHz(P95 stable), Corsair H100 cooler, a CoolerMaster 1200W PS and two GTX 680's in SLI. Except for one experience(see below), G.Skill memory has always worked per spec the first time!

Cons: Cost, No stable OC @ 2800 and above yet

Overall Review: I had originally bought the 2600 version of this memory and could not get a stable XMP OC above 1921 MHz. I talked to Tim(very helpful) at G.SKill and tried everything he suggested(i.e. Vccsa should be @ 1.25v), but still no luck. RMA'd the part back to NewEgg for a refund and decided to buy the 2666MHz set. 2nd time was a charm, and NewEgg really treated me very well during the whole process!!

Pros: I own three of these P256's. I have two in a RAID 0 cofiguration in my ASUS P5E3 Desktop(Win7 64 bit WEI score=7.9). I have another one in my new ASUS G73JH-A1 Laptop(Win7 64 bit WEI score=7.4).

Cons: Price and Babysitting -- you have to ocasionally do a secure erase with G-Parted to get them back to top notch performance. Trim commands work with single drives and Win7, but don't work yet in RAID(multiple drives) cofigurations. I will be very happy when the RAID controllers allow the Trim command to be passed through to the SSD Drives.

Overall Review: They really shine in my ASUS G73JH Laptop!!!

Pros: I own two of these. Very fast in RAID 0 configuration. Windows7 64 bit WEI score = 6.3. Fastest hard drives on the planet. They are faster than the 300GB Velociraptors and much faster than the 150GB Velociraptors.

Cons: Pricey

Overall Review: Only my two Corsair SSD P256's in RAID 0(WEI=7.9) beat the WD Drives which is to be expected. But, the SSD's need more babysitting(ocasional G-Parted secure erasing) to keep them at top notch performance.

Pros: Works perfectly @ DDR3-1600 @ 1.8v(two sticks). I was able to take this DDR3-1600 (4GB) memory and pair it with Corsair's TW3X4G1800C8DF(4GB) and wind up with 8GB (4 sticks) operating at DDR3 -1600MHz(@1.8v) with my P3E5 Deluxe ASUS Motherboard. I am really pleased with the results!!! QX9650 = 3.8ghZ(9.5x) @1.375v - CPU and Memory Win7 64 bit WEI score = 7.5

Cons: None

Overall Review: This memory(TW3X4G1600C9D G) must be in the black slots and the Corsair TW3X4G1800C8DF must be in the orange slots. Also, Strap must = 333MHz and the FSB must equal 398MHz(max). Ai Clock Twist = Moderate. When the FSB > 398(i.e. 399 MHz or greater), I could not get the computer to post. At 398 MHz (and lower) my computer passed all memory testing and a 24 hour Prime95 torture test. I think the reason for the wall at 399MHz(or greater) is the P5E3 Motherboard tries to implement a Profile(1600 to 1800) at that FSB that doesn't work with 4 sticks. If I can overcome this wall I will report!
