Re: [Tutorial] How To Build Your Own PC

[quote user="Nik" post="40633"]Um, if you could try to explain which Windows works with which processor type --1, 2, 3, 4 cores, 32/64 bits-- and how much RAM --2,3,4,8, 16 GB etc etc is accessible to their programs, it would help.

Well, on Windows 32 bit operating system the maximum memory is 3 Gbytes, you can install more, but it will see 3 Gbytes. For more, you need a 64 bit version , XP or VISTA 64. And with a single core CPU you can only install a 32 bit OS.

So, if you've a single core CPU you can install a 32 bit operating system and with windows (as far as I know it doesn't happen with Linux...) you'll see 3 Gbytes of memory
If you've a dual core or greater CPU you can install a 64 bit operating system and more memory (as far as I know till 128Gb on Vista 64) , you've also to enable memory mapping in the PC bios if it is disabled.

In any case if you plan to buy that CPU you know what to do, buy some thermal paste and clean the base of the cooler fan (with a branded toilet paper...) . If you don't have an air compressor, take also one of those bottle of compressed air, the dust into the case is terrible, bring it in open air and clean it with compressed air...
