I take it that the 1.5 is in GB since no computer can run on 1.5MB of RAM. So the 1.5GB is higher that the 512MB RAM.
512 ram
the cost of 512 m.b ram is [ R\S 750 ]
Actually it is quite the opposite. The more RAM you have the more speed at which data can be transferred to the RAM. An example is if you have 512 Mb of RAM then 512 Mb of data will be transferred to the RAM at a time, but if you upgrade it to 1 GB of RAM then 1 GB of data will be transferred to the RAM at a time verses the 512 Mb. So the speed at which the RAM stores data will increase if the size of the RAM is increased. I hope this answers your question.
It may be two slots of 512 installed
512 mb
A stick of 512 megabytes of RAM can hold about 512 megabytes of data. It cannot, however, store it for long because it is volatile and is not designed to store data.
512 to 1gb ram are recommended
Most computers have space for 2 ram chips so this includes your 512 and 1 gb ( it should work as long as it is the correct chips for your computer)
512 mb of ram is the total capacity of the 2650.
No you can't. You need at least 1gb ram.
work neeed for speed world with 512 of Ram
Yes.
