Pros: This memory nice and efficient. Most motherboards won't OC ram with all DIMM slots filled so this is a much better alternative than using 4x 2GB dimms. Runs very stable at 1600 MHz 9-9-9-24-88-1T at 1.35v. Haven't tried to do any overclocking with it yet but after testing in SiSandra I'm getting 18.8 GBps. I switched from a 4GB kit (2x 2GB) of Adata XPG gaming series ram also 1600 MHz rated, one of the highest rated ram kits on newegg and I could barely manage 18.0 GBps at 1.65v after tweaking the voltage a lot. All in all good blend of speed, stability, and capacity at a good price.

Cons: The heat sink was a little loose but they're just held on with clips. It is plenty snug enough to stay on the RAM, it just slipped a little bit when I was mounting them in the DIMM slots on my Asus Maximus III Extreme which is notoriously very stiff anyway. No big issue, I just mounted the Ram and made sure to push the heatsink back on all the way.

Overall Review: Using an i7-875k on an Asus Maximus III Extreme motherboard. CPU: 3.6 Ghz Vcore: 1.15v IMC (Vtt): 1.13v DRAM: 1.35v RAM: 1600 MHz 9-9-9-24-88-1T

Pros: Great speed, 8 threaded performance. Easily hits 4 ghz. Outperforms most of the i7-900 except the new 6 cores. Blows 4 and 6 core amd's out of the water in most benchmarks.

Cons: No heatsink but anybody buying an unlocked chip will want to use their own anyway.

Overall Review: Using an Asus Maximus III Extreme Motherboard with Dynatron G950 Heatsink 4.0 ghz hits 70-72 degrees at max load in prime 95 highest normal load temps are 60-65 at about 1.28v.

Pros: Works very well, smooth fan noise. Not as heavy as some of the really large air coolers. Very tight mounting lets the heatsink base press all the way into the cpu for maximum thermal conductivity. In a performance class well above its pricepoint.

Cons: Mounting can be a little tricky, however once you figure it out it's actually quite simple and works very well so I don't really see this as a con.

Overall Review: Running an i7-875k OC to 3.8 Ghz stable with this cooler. Was using a Corsair H50 before and at 3.8 would spike the temps up over 75, now they run around 70 at full load which is what I wanted. I wanted to have the highest stable overclock without going over 70 degrees. Other Components: Case: Coolermaster HAF 932 Motherboard: Asus Maximus III Extreme CPU: Intel Core i7-875k @ 3.8 GHz Memory: Adata 1600-DDR3 GFX: 2x Asus GTx 470 SLI PSU: XFX 850 Watt Black Edition

Pros: Runs faster than advertised. I'm running mine at Max stock voltage 1.75v at 1600 mhz with the timings set at 7-8-7-24-1T. Runs very quickly and very stable at these speeds. Haven't had any stability issues so far.

Cons: Doesn't support XMP but if you're going to custom tune it up faster anyway who really cares?

Overall Review: Running these sticks with an i3 OC to 3.52 Ghz on an ASUS Maximus III Extreme Motherboard. I plan on upgrading to an i5 or i7 soon but it still runs fast enough for now. Using an XFX 850watt PSU and an Nvidia gtx 470 in a CoolerMaster HAF 932 case.

Pros: Very cheap, nice airflow, does what it's supposed to. Very simple installation just clips on and you plug it in.

Cons: Not really a con, but at full speed this is quite loud (think graphics card fan at full speed). I went into the bios settings on my motherboard and backed it off to 60%, nearly silent now and still works very well.

Overall Review: Current system: Case: Cooler Master HAF 932 Motherboard: ASUS Maximus III Extreme CPU: i7-875k OC 4.2 Ghz RAM: ADATA 4GB 1600 Mhz Graphics: Nvidia GTX 470 PSU: XFX 850 watt
