Pros: Truly SPD compliant memory. Solid performance and quality build. With default settings, they produce little heat, hence the cost savings of no heat spreaders from the factory. They are 100% factory tested and have a lifetime warranty. All these positives make this Signature series DDR2 extremely hard to beat.

Cons: Nothing I would consider a "Con".

Overall Review: I have three 2 gig sets total, running one set in my file server, one set in each of my desktops. Since my desktops do not have the optimum airflow found in my file server, I purchased a set of Vantec copper spreaders for each of the desktops. They were inexpensive and work wonders in the "hotter" environments. For those with motherboards that have trouble auto adjusting via SPD, manually set everything except the voltage. Leave it on auto. Most will work fine and report 667 as expected. For Intel chipset boards, auto everything seems just fine.

Pros: Works great, I guess. Didn't work in my application, but for everyday users, it'll be fine.

Cons: Bought this for a server, but it doesn't have ECC, so it doesn't work. :( Works fine otherwise.

Pros: The original set that I ordered back when I built my entire computer from the ground up worked perfectly. It got me through almost two years now with only two gigs. Never gave me any problems, I thought I had found a brand and seller I could trust.

Cons: I just ordered a second set, so I'd have four gigs sitting in my system. I received my second set and carefully put them into their ports correctly. To my shock and dismay, they had sent me a gig stick with a 256 stick. How? Why? Last time I checked, these things were each individually tested before leaving the factory. Maybe I was wrong to think that Patriot was work my time, money and trust.

Overall Review: I made the mistake of ordering prior to a holiday. Considering I was a very small distance away from the shipping location, it took longer than it should have to have gotten here. Never had such horrible service from Newegg since I started using them. A real shame to be frank.

Pros: Very high quality DDR2 memory. SPD works as advertised. Properly sized to fit memory slots without overstressing. Company reputation has risen greatly over the last 2 years to match the quality of their products. Great coverage as well.

Cons: None

Overall Review: Just purchased 2 more to max out my Intel motherboard. No dead sticks. I use copper heat spreaders to help dissipate heat. They produce as much heat as any other stick of memory, so spreaders are still a good idea. I use Vantec’s. Don’t worry about the need to spend more money on other brands. There is just no need to.

Pros: Cheap, decent speeds, and guaranteed to work with your motherboard.

Cons: No heatspreaders but you can buy some off newegg for a few bucks anyways.

Pros: They run perfectly, and are completely compatible.

Cons: None

Pros: One of the pair was dead but the good one worked first shot with my Gigabyte S3 with e6300. I have been able to overclock the one that is good to 1020mhz (340x3) with +.1 voltage! Ran a little warm but running memtest overnight did not crash.

Cons: One DOA out of the two sticks but NewEgg instantly RMAd the set and I ordered a new pair.

Overall Review: As far as I can tell, this RAM screams for speed and works fine in a usually fussy realm of MB/CPU combos. For the guy below... 64mb on each chip times 16 chips (front and back) = 1024

Pros: Works great, pluged it in with other ram already on my system and no problems. The bios found it immediatly and rated it at 677

Cons: none
