Pros: 1) Cheap 2) It works. :)

Cons: Wasn't free.

Overall Review: The PM965 chipset in the Lenovo T61 was never validated to work with 4GB SODIMMS. These modules will work though, since apparently the chipset will work with 256Mx8 chips (which is what the Hynix chips are on these modules). Keep in mind not only that Lenovo never validated this to work, but that Intel never validated the PM965 to work with anything larger than 1Gb tech modules. These modules get away with working on the PM965 since although it's 2Gb tech, the modules are arranged on the SODIMM in a 256 x 16 chip fashion (which apparently the chipset can use). Keep in mind too that 512Mx4 modules most likely WILL NOT work, so you will not be able to use other SODIMMS that only have 4 modules per side of the DIMM. BTW, I'm using Bios 2.26 on the notebook too. :)

Pros: Great price compared to other memory.

Cons: None that I know of.

Overall Review: Was somewhat concerned by reading other reviews, but with NewEgg's return policy and my own previous interaction with GSkill's support, I felt it was worth a try. The first thing I did was run MemTest and did one full pass and there were no problems. I did notice that MemTest reported the timings as 6-5-5-18 (or something like that - I don't remember exactly) and that also it registered as DDR2-667, but as GSkill already noted in other reviews here this is pretty normal with many systems when you max out the memory. Time will tell, but I am happy I made the purchase.

Pros: Nice box and a free USB thumb drive.

Cons: Did not work in dv7-3065dx, bios version F.04 or F.08. Just blinking lights for incompatible RAM.

Pros: Works great in my Asus G60VX

Cons: None, install and forget

Overall Review: wish they were cheaper..on another topic, prices on newegg fluctuate worse than the stock market...this is starting to anoy a lot of people including myself

Pros: Reasonable price for matched set of 4GB SO-DIMM modules.

Cons: Not compatabile with HP DV4-1275MX. Latest Bios, F.4A, has been installed. Same speed, timings and voltage as origional memory. Will not post, only blinking lights on keyboard.

Pros: bought this for my Dell Studio 1737, worked flawlessly! Initially, I bought Patriot memory with the same specs and was getting BSOD. I was using gskill for a while now from desktop to my other laptops and my loyalty is with GSKILL

Cons: none

Overall Review: Thank you NEWEGG for helping me out and excellent customer service!

Pros: Works perfectly in my toshiba t-135D. Nice to have the extra memory. Now windows 7 run the way it should and I can have multiple sessions of visual studio open.

Cons: None

Pros: The kit installed in an Asus U81A-RX05 laptop. On Asus's support site, the model is U80A(Best Buy). The BIOS (Version 210) recognizes all 8GB of memory. Windows 7 Experience Index is 5.6 for memory. CNET indicates the maximum installed size is 4.0GB. The laptop has the Mobile Intel GM45 Express chipset, further research on Intel's website confirmed this chipset supports 8GB of memory.

Cons: None.

Overall Review: The review by Yuri on February 22, 2010 was helpful. Even though I had a different Asus laptop. This was a gamble and it worked. Price is not too bad for an 8GB kit with 2 x 4GB modules. My second memory upgrade kit by G.Skill without incident. Crucial.com wanted about $380 for a similar size kit, saved about $150 with this kit.
