Summary: I don't know how to make a recommendation whether this will work for you or not. I tried two of them in my aging ZE4500 laptop and neither one worked. I decided to order from a site that has more information in the description.
Pros: It's a good price. It's made by Crucial, one of the top brands. Shipping is free. It has a lifetime guarantee (assuming it's compatible in the first place).
Cons: There's not enough information provided in the part description to know if it will work for you or not. If the description said "low density" or similar, it might help. PC2700 is not always PC2700. Compatibility depends on the specific configuration of your product, and maybe even the BIOS revision.
Summary: I'm sure this is somehow self-evident to the more alpha geeks among you, but I matched the (more complete) specs I had printed on the old stick to the (less-complete) spec listed on Newegg (less) and still no dual-channel.
Pros: Solid RAM for the type it is, memtest86+ likes it. Crucial modules I've had before seems to be good.
Cons: Not fully compatible with older sticks of the same P/N. I bought this to upgrade an older box that already had a stick of Crucial CT6464Z0B in it, and bought this partly to maintain dual-channel memory mode. This new CT6464Z40B runs fine, but only in single-channel mode; it won't dual-channel wit...
Summary: Ordered this memory for a Dell Inspiron 1100. Both Dell and Crucial recommend this speed memory with a max of 1gig(512 X 2). System would not boot with new memory even after bios flash. Other trouble shooting site with same problems recommends DDR266 (PC 2100) 1gig (512 X 2)
Pros: Newegg has refunded funds from order so correct memory can be purchased. Thank you newegg for your always top of the line service!
Cons: System would not boot after recommend memory was bought.
Summary: i have been building systems for a long time and this is a new one on me asus a8n5x board
Cons: installed this set to match an exact set already installed (same kit number) to give me 2gb, as soon as i installed the set, the computer only reads all 4 chips as ddr333?? it reads original 2 chip set as ddr400
Summary: Stay away until Crucial turns their packaging design back over to engineers instead of accountants.
Pros: It works. I've used Crucial memory for eight years and have never had issues with stability or DOA parts.
Cons: The new packaging is a disaster. The modules are completely unprotected from ESD, and they come in those ubiquitous plastic nightmares with the edges sealed so they must be cut open. Removing them without flexing them is a delicate exercise. My first Crucial memory came in a sturdy cardboard box ...
Summary: This is the RAM that the Crucial website said I needed for my notebook. Plugged them both in and nothing would come up on the screen when powered on. Tried them individually and nothing would happen either. Put the old memory back in and it works fine.
