Q) I have 4GB of memory in my system, why can’t I use it all?
A) Because 32 Bit Windows can’t address more than 4GB in total (including graphics card) you need 64-bit windows to use it all.
Q) My memory is listed as 400MHz, I dont have 400MHz RAM, whats up?
A) DDR means Double Data Rate. This means whatever the base or raw frequency of the memory is, it's effectively doubled. This applies for DDR, DDR2, DDR3 and their graphics card derivatives.
So for example:
DDR2-800 has a raw frequency of 400MHz. This is what CPU-Z picks up.
Q) I've just added some memory to my computer, now it wont boot up. Whats wrong?
A) The first thing to do when this happens is to check that you have got the right memory. Memory comes in various speeds and is not always compatible, even if it physically fits the socket on the motherboard.
After you've done that, remove the memory you added, and try turning on the PC. If this works it is possible that your new memory is faulty, or just isn't compatible with the memory you already have.
One way of finding out whether the memory is faulty is to remove your original memory and try booting it with the new memory, if it works then it is likely to be incompatible with your current memory.
If it is faulty and is in warranty the best thing to do is to return it as soon as possible for further testing and replacement.
A good tool for testing memory is Memtest. You can get memtest from here http://www.memtest.org/
Q) I've just added memory to my machine but now it shows a blue screen. Whats wrong?
A) When this problem occurs it is possible that the memory timings have been set incorrectly or that the new memory is just faulty, also it is possible that your motherboard isnt supplying enough voltage to the memory. To check this you need to have a look on the manufacturers website for any specific timings and voltages. These can be set in your computers BIOS. To test that the memory is actually faulty a good piece of software to use is mentioned above, Memtest. Running Memtest will show whether there is a problem with your memory, if there is and it is under warranty, you can return it for further testing and replacement.
Q) What are the different types of memory and what sockets do they go into?
A) In order to answer this question I have looked to Wikipedia to provde all the info.
http://en.wikipedia.org/wiki/RAM - an overview of RAM
http://en.wikipedia.org/wiki/SO-DIMM - SO-DIMM Memory (commonly used in Laptops)
http://en.wikipedia.org/wiki/DIMM - DIMM Memory (Mainly used in PCs)
http://en.wikipedia.org/wiki/Double_data_rate - DDR memory technology
