Question 1

Will this work on my Lenovo  ideapad Y450?

Accepted Answer

if they are the same buss speed I don't see y not     but I would go to Lenovo web site  and check      I put mine in a acer    but put  1 chip  in and start it up    then  shut down and put the other one in  and then start it up    so its not too much memory all at one time       good luck            my laptop runs a lot faster with the new memory in it

Question 2

Is this item compatible with MacBook 5,5 mid 2009?

Accepted Answer

I will have to double check which my is but mine runs these fine.  I have occasional crashes but I don't think it is the ram.  It is a little hard to get it to fit cleanly.  The clips on my Mac did not grab the dims well.  I think I would recommend a different kit.

Question 3

Will these cards work in my MacBook, Dec. 2008 model, Processor  2 GHz Intel Core 2 Duo, with OSX 10.9.2?  Currently I have only 2GB memory.
Thanks!

Accepted Answer

I think they will work just fine. My wife had that very same model MacBook and I upgraded her machine with similarly spec'd memory which functioned as it was expected to. The chipset on that computer's motherboard only accepts DDR3-1066, it will not down-clock faster 1333 stuff. Going with 8GB is a good idea; that's the best low cost upgrade to this model computer.

Question 4

I have a 13" Macbook Pro, mid-Summer 2010.  The specs match to what the apple website says, but I've read other memory brands that match the same specs but it didn't work.  Does anyone have any experience with this particular brand?

Accepted Answer

I bought this particular memory for my '15 Late 2008/Early 2009 MBP at the suggestion of my developer co-worker. I'm not an Apple Genius by any means, though not completely new either, and I had very little problems installing them (2nd card was a bit difficult to snap in, a few tries did the trick). I also noticed a considerable difference on first startup. I'm still loving the upgrade and having no problems. I'd recommend.

Question 5

Will this work for a Macbook (Late 2008, Unibody) running Lion 10.7.5? I hope to update to Mavericks.

Accepted Answer

According to Everymac it should work. It is the right speed and the model supports a max ram of 8GB.

Question 6

Is this compatible for a mac mini 2.4 duo core  1067 mgHz  DDR3?

Accepted Answer

Yes, up to 16GB

Question 7

Is this compatible with a MacBook Pro 15" Mid-2010 Core i5 2.4GHz ?

Accepted Answer

You need to look-up your computers ram specs.  If this kit matches your laptops power and profile specs it should work.  Especially pay attention to the rams voltage.  You should be able to look-up your laptops hardware specifications on Apple's website or just use Google.  You'll need to have your computer's model and serial number.  Since you didn't list this info I can't look it up but it shouldn't be too hard to check.

Question 8

Is this model nonparity? Does it feature PLLs? Thanks.

Accepted Answer

Yes it's non parity and as far as plls I'm not sure

Question 9

Will this (2 x 4GB) work with my TOSHIBA Satellite Model P505-S8025 Part Number PSPGSU-0DL002?

Accepted Answer

I’m sure they will work fine, but you might want faster RAM (1333MHz instead of 1066MHz) which should be similar in price.  It should support both speeds natively.
