Z1 RAM

How much RAM is reported on your Z1? It's sold with 2GB but every info app I use says 1695MB...

See this topic,we are debating the same there:

/t5/Xperia-Z1-Compact/Tech-specs/m-p/942936#M13707

Those 1,6 GB usable are what's left from about 1,9 GB that are available on the device (out of 2GB).

@Don_Quixote Contact your local Xperia Care and request an official answer if you feel cheated (based on your reply to the other thread)

It seems 200 MB of RAM are used from the box, according to the whitepaper. And to get to 1700,there are 100 more that cannot be explained. But after my way of thinking (even though I am not sure it applies to RAM as it does to internal memory), from about 1.9 GB available, you end up with the 1.7 for normal use.

Thanks guys! They must have found a new meaning to dynamic random access memory 😉

This is quite simple really you could go a route which most people do and multiply 2GB by 1000 and then divide it by 1024 giving 1.95GB which is readable but is wrong.

There are two correct ways after doing some math is to multiply 2 by 0.9313226 giving 1.86 readable memory, When you start using TB you multiply the amount of TB by 0.9094947 so for example if you have one, A 2TB drive multiplied by 0.9094947 gives you 1.81TB readable

Another way which is also correct is to multiply 2 by 1000, 3 times IE: 2x1000x1000x1000 then divide that by 1024 and again 1024 and again 1024 giving the same answer 1.86GB readable

These are how you get actual readable memory as to what is advertised - Try it yourself on your Pc's hard drive using these calculations

@Thommo it means I was on the right path, I did explain this in the other thread for Z1 compact.

Although they are only referring to storagespace and not DRAM 0:-)

This is something cool,I knew there were differences but now I notice there are also differences in how you write.

Hard drive or Ram - Same thing and the same applies - For example on a Pc if you check the system properties it will read the amount of Ram but say useable

@Thommo DRAM on my UX31A 4GB but total physical in process explorer is 4.077.544K...
The 16GB in my desktop is reported as 16.775.216K which is nearer to 16*1024^2 than any other equation

WIKI on DRAM on DRAM and off course to keep it all crystal clear WIKI on RAM
