4 out of 5 eggsDell demention 5100 upgrade

Pros: upgraded from 1 gb to 4 gb have not tested to see if i can get the full 4 GB with 2 of these kits installed but it shows 3.5 gb useable in in lubuntu 13.10

Cons: not really a big deal as long as it keeps going but the timming does change to 4-4-4-12 and not 5-5-5-18 i suspect thats because of the voltage is probably locked by default by dell

4 out of 5 eggsGood Warranty

Pros: Corsair Memory DDR2 lasted 3 years and they stood behind the warranty and were quick to replace it but watch the web forms you fill out as mine went to the wrong dept. and I had to call but the customer service was great and very helpful so in less 30 days I have my new replacement and it would have been sooner but for their confusing web page makes and models offered do not quite match all their products!

Cons: Web Master or page designer needs to update the kinds of products so you can match your product Make, serial, and model correctly!

Other Thoughts: Am pleased due to a very courteous man in their customer service department that went out of his way to fix my problem!

5 out of 5 eggsGood RAM

Pros: I use Corsair RAM any time I can, as they have been pretty reliable for me. This set put a little extra juice in an old PC I'm setting up as a home server. Will keep buying Corsair until they stop working.

Cons: None.

Other Thoughts: I guess with RAM it's sometimes a toss-up as to what people should buy, especially when you're not building a gaming rig. I think it comes down to brand familiarity and looking at the past reviews. Let me say that I have gotten bad RAM from Corsair before, but the few times I've had to use their RMA process it's been fast and easy. I think people should buy this with confidence.

3 out of 5 eggsNot the same as it once was...

Pros: First this is not intended to be a "bad" reveiw and in no way should reflect on NewEgg as they are always great. The memory works as it should and the specs match what is listed on the website. Gave me a scare when first installed (post error beeping) but after reseating twice it began working.

Cons: Specs for this memory has is slower than it once was.

Other Thoughts: This review is really a bit of a complaint to Corsair. I purchased (2) x 1GB of this memory three years ago for my son's computer partly because it was about the fastest thing going at the time that was compatible with the computer it was going in. When I decided to add more memory to his computer I ordered the same model memory. My fault for not verifyting the specs but the model number and everything was the same "CORSAIR XMS2 TWIN2X2048-6400". When I went to install it I was suprised to find the newer memory was slower than the older memory???

The 3yr old Corsair XMS2 memory has 4-4-4-12 timing.
The new Corsair XMS2 memory has 5-5-5-18 timing.

My fault for not verifying the specs were the same before ordering but and I am very disapointed that Corsair is selling the same model memory with much worse specs.

Also disapointed since I could have gotten CAS 4 memory from another well know manufacturer for about the same price.

5 out of 5 eggsRam

Pros: 4 years into it, and still going strong.

Cons: Zero

Other Thoughts: Corsair makes a good quality set of RAM sticks. From what I hear they still frequency test every set of sticks before they ship them.
That's not to say that other Companies do not.
I've always been pleased with all of the products I've gotten from Corsair.
I bought a mid-tower the other day through here from them. We will see about how I think the cable management is.
But that will be another review.
