I've just bought 2 x 4gb Corsair CM3X4GSD1066 memory bricks. I've now however read that people have had problems getting these to work on a W500 - but is there a way to do it or should I just return them ASAP? If so - what bricks will work? If any ...

I've had no trouble getting 16GB of RAM to work on a W510 (which is largely the same as a W500, but those only support 8GB and I don't think I've tried more than 6GB on one...), but I've never tried these particular DIMMs. (I have never had luck with Corsair.) I was using Kingston, personally. Really, though, the best thing to do is buy the RAM directly from Lenovo - it may be slightly overpriced, but it will carry the warranty coverage of the laptop if you do this!

what RAM did you use to get 16GB of RAM to work on a Lenovo W500? –  user82057 May 23 '11 at 14:19

@antheo - Doh, this is totally a typo on my part. The W500 only supports 8GB - I meant a W510. >.< They're largely the same except for that which was sort of my point - ThinkPads are pretty robust. (I edited the post - thank you.) –  Shinrai May 23 '11 at 14:43
    
16GB will not work in the w500. I just tested it with 2x8GB team ram sticks. The computer makes a pattern of beeps and then shuts off without displaying anything on the screen. –  ntw1103 Feb 16 '13 at 22:43
    
@ntw1103 - That's what it says - the 500 series doesn't support that much. –  Shinrai Feb 17 '13 at 4:37

I know, I just wanted to iterate that it has been tested. :) I was once told you couldn't use an intel 6250 wifi/wimax card in a thinkpad x60t, even with an unlocked BIOS. It actually was possible after covering pin 15 on the pci-e card. I did mark your answer as useful. –  ntw1103 Feb 17 '13 at 18:35

You need to have a 64bit OS to have all the 8GB viewed/usable that's all You can stress test these RAM using Memtest?

Or you could use a 32-bit OS that uses PAE. Each process would still be limited to 4GB of address space though. –  Ignacio Vazquez-Abrams Oct 19 '10 at 15:04
    
Yeah, I have x64 but what do I have to do to make the RAM viewed/usable? –  Riri Oct 19 '10 at 16:00
