Please check the operating instructions (or the Internet) to see which RAM is supported.

Hello, if you have four memory slots you can do this, but if you only have two then you have to buy 2x 8GB.

After checking the Dell website, it should be compatible.

Yes, that is possible. If not already installed, I would install an SSD for the OS and the existing hard drive as an additional drive. The gain in speed (booting) is striking.

Yes they fit the iMac mid 2011, I upgraded mine to 12GB with them. Recommendable!

Yes, that should work according to the specifications. PS: So for me, the support page only comes up in English. It says "Non-ECC memory only, unbuffered" and not "Only-ECC memory, unbuffered".

The device seems to support a maximum of 4x 2 GB (with a windows 64 bit) according to this link: http://www.crucial.com/usa/en/compatible-upgrade-for/HP---Compaq/pavilion-p6520ch this means something like this would fit: Kingston Value RAM (1x, 2GB, DDR3-1600, DIMM 240) here is the link to your device from hp itself: https://support.hp.com/ch-de/product/hp-pavilion-p6500-desktop-pc-series/4162263/model/4234755/document/c02512409

According to HP, this memory should work in your PC: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c01865794

Sorry, can't say, I use the RAM for an HP DC5800 Microtower.

The Dell Latitude E6510 does not support high-density RAM. I recommend that you only use RAM recommended by the memory manufacturer in this case. It is also not recommended to mix different memory modules from different manufacturers/brands. For 8GB, a duopack of 2x 4GB is recommended.

Yes, they are compatible with each other.

Non--ECC, laut Herstellerseite: http://www.newegg.com/Product/Product.aspx?Item=N82E16820239311

Kingston itself knows this with very good accuracy: http://www.kingston.com/de/memory/search/options/ Simply enter your model/type and all available options will be displayed. You can then check whether the modules are available here at digitec. Good luck!

I upgraded my Lenovo T520 a few weeks ago, runs without problems. I'm sure it will run on the Lenovo W520 as well, as it has the same RAM support.
