Mushkin Enhanced Essentials 4GB (2 x 2GB) 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Dual Channel Kit Laptop Memory Model 996559

Pros: received in 2 days

Cons: didn't work in my Toshiba P205d Vista 32bit O/S l/t. Unstable, only recognized 3.6G instead of 4G. Single Dimm registered 1.87G instead of 2G. locked up with both installed after about 5 min. differant combo of original 1G Dimm and 2G Dimm only registered 2.87G. This combo worked for a few min, blue screen and l/t shut off before able to read. Next boot worked for few min again, then blue screen which said memory problem and shut off the computer. Single 2G worked ok for awhile, got tired and r&r Dimm with original 2x1G Dimm. I'm not sure if defective or timing problems. Hope next units work.

Pros: They fit rather snugly; were not DOA.

Cons: n/a

Other Thoughts: Got them to boost the performance in my 2008 white macbook. I'm up from the factory 1gb of ram and the boost is really noticeable in a little bit of stress testing (multiple open office files and running a stream). Kinda thinking about using another open source office suite for macs to see if there is any kind of difference.

I hope the current QC has eliminated the problems described in the low reviews from 2006-2011.

Pros: Good price, sped up my 2007 Macbook (white) considerably. No problems with installation. Still running with no errors after almost a year.

Cons: None

Other Thoughts: Great customer service

Pros: Added 2x2GB RAM to my 2008 ,4,1 Macbook pro.
Cannot believe the difference in speed.

Cons: None so far

Other Thoughts: Newgg has always amazed me with the value pricing and lighting fast shipping

Pros: Works just as advertised. Wouldn't expect anything less from Mushkin.

Cons: None so far

Other Thoughts: This along with a OCZ ssd breathed new life into a 4 year old Toshiba laptop. So far very pleased with the results.

Pros: Great price. Mushkin always makes great products. Works just as expected. This along with an ssd gave new life to a 4 year old Toshiba laptop

Cons: None so far

Pros: plopped these little guys into a late february 2008 macbook. works fine. good speed increase from 2 gigs.

Cons: nada

Pros: Great compatibility- this was installed in an old Dell Vostro 1000 so I could upgrade to Windows 7. Dell says that the Vostro is limited to 2GB but this 4GB kit works perfect. I've never had a problem with Mushkin memory- including my desktops.

Cons: none

Pros: runs windows Vista 32bit very smoothly
large enough for a small RAMDisk
excellent $/GB for DDR2

Cons: wish DDR2 was cheaper

Other Thoughts: great RAM, after installing on a rather old laptop running Vista it has boosted the video capability greatly. Overall one of the best upgrades I could have done to such an old machine, next upgrade will be an SSD for the OS and use the current 80GB as storage. (2 SATA bays)

Pros: Upgrading 2x1TB Mushkin (over 4 years) to 2x2TB Mushkin. Excellent packaging (simple, secure, easy to open, convenient to store old modules). Reasonable price.

Cons: None.

Other Thoughts: I was bringing an old Dell Inspiron 1501 (AMD Turion) from 32-bit Windows XP to 64-bit Windows 7. I upgraded the RAM (more) and the HDD (hybrid, larger, faster) at the same time. Wow!
