Question: Will this work in a lenovo e520?
Document: I'm not exactly sure why, but it didn't work on my lenovo g460. All the (usual) specs were right, but still didn't. I ask for a replacement, with no luck. I bought another brand and it worked
The one that was shipped out the twice has a single row of four chips on the SODIMM, and my Lenovo T500 just beeps twice and shuts off. I've had to return both orders.
This is notebook memory (even though the picture shows desktop memory). Works well in my Lenovo Edge notebook. I am now running with a total of 5GB (was 2GB).
This RAM is working fine with my Lenovo T420 but it is not working fine with Imac 27 bought in september 2011.Imac 27 recognises it but effective memory is not increasing.
I tried to install this RAM ( KVR 13S9S8/4) in my Lenovo T410  2537 , but Windows 7 64 bits , don't  function. Lenovo says that this card has a very high density , so they recomended the KTL-TP3B/4G . Who is the responsable : Kingston , Lenovo or Amazon? Please , help me with any comment. Thanks.
Does not work with Dell XPS L501x but it does work with Toshiba Portege R830.
Made all the difference in the world. Bought this for 3 different PCs and they all work SO much better now.
when mixed with dell sodimm, lots of blue screens , maybe it would work if installed in matched pairs ,
While I can get this to work on one computer I can't get it to work on the computer it was purchased for. Very frustrated.
Ram either works or it doesn't. If it works, I give 5 stars. If it doesn't work, I'd give 1.
