Pros: Works as advertised. i ordered this as a replacement for Corsair that was not compatible with Asus P5W-DL.

Cons: none yet

Pros: Very fast, overclocks like a beast.

Cons: Memory errors. I RMA'd the first pair I received due to Memtest86 failing when this memory is running at its advertised speeds. When the speed was decreased to 667mhz, the errors were less frequent but still present. The new sticks that NewEgg shipped to me STILL had errors. What are the odds? So, I would steer clear from this memory. I've never had problems with GEIL in the past, but this model seems to be very error-prone.

Pros: cheap, fast memory. runs at a slower default setting until you set the 2.0v and quicker timings in the bios. Looks cool. works great

Cons: none

Pros: Works great second time around.

Cons: First pair i ordered i had to send back due to a bad stick. Second pair i recieved worked fine. Be careful as you may have to RMA.

Overall Review: dont buy this ram if your'e putting it in a MSI P965 Platinum mobo. The mobo uses cas 5 & 6 latency ram. Had to change setting to cas 5 for cpu to run stable and totally defeated the cas 4 purpose.

Pros: Great RAM, once I got the timings right.

Cons: My mobo (Asus M2R32-MVP) auto clocked the voltage @ 1.8v. Got the other timings right @ 5-5-5-15 @ 800MHz.

Overall Review: Vista Ultimate 64 had constant blue screens and restarts until I manually set the voltage to 2.30v. Works perfectly @ 800MHz, until I get a bios update that'll allow me to OC it higher.

Pros: Please read cons first! Very nice color. Looks good on the MOBO. Over clocking this RAM is fantastic - when it works!

Cons: Where do I begin. I bought this RAM after reading the reviews, seeing a 54% between 1 and 2 on other people's reviews. I should have known better. The RAM didn't POST when I got it - BEEEEEP beep beep - tech's will know what I mean. Took out one stick and was able to get to the bios, even though the system constantly was hanging. Upped the voltage to 2.25 (wanted to stay within the manufacturers limits). The RAM is rated at 1.8-2.3 volts. Got it to finally POST with the 2.25 voltage (tried everything between 1.8-2.25 at this point), but constant hangs or tells me that my video card is bad (BEEEP beep beep beep). I then discovered the 2.7-2.8 volt stuff on their website. Contacted customer support, who is there between 9am and 6pm mon-fri only. Sent them an email, still waiting on a response. My MOBO will not handle anything over 2.5 volts. I upped it to that, and can get my computer to run - SOMETIIMES. Just stay away!! Listen to the rating numbers!

Overall Review: Stay away! RUN AWAY!

Pros: Price

Cons: Does not run at rated speed of 4-4-4-12 with MSI P965 Platinum. I played with several voltage settings and it still did not work. However, if manually set to 5-5-5-15, the memory works perfectly and 100% stable.

Overall Review: It is still the cheapest you can get without rebates, but if you can pay more now and get the rebate later, I would spend some extra on Cxxxair ram.

Pros: Runs fast and does what I need it to do

Cons: None yet

Overall Review: Kind of expensive but worth it
