hey i can answer a few of these for you
1) 2.2ns and 2.8ns are indeed ram speeds.....these are time periods for the ram and their speed in Mhz is given by the formula F=1/T (t being the time period
ns stands for nano-seconds and this inturn stands for the power of 10 that the number is given in the case of 2.2ns.......
2.2ns = 2.2 nano seconds = 2.2 x 10^-9 (this is times 10 to the power - 9)
this will give you a very small number........all you do then is press the inverse button on ur calc, or just do 1 divided by that number and that will give you a speed in Mhz.
then you times this by number to get the effective memory speed as all of todays cards use DDR (double data rate)
2.2ns = 454mhz.........in DDR terms that means 909mhz!!!
2) i have no idea...probably gives light a 3D appearence or sumthing
3) a game engine is simply the code that lies at the base of the game....ie physics calculations etc........its just a bunch of high level maths. it also responds to your inputs..press the mouse and the game engine will interperate that into firing a gun or jumping etc
4) no idea, im not an intel man nor am i that sad to bother looking which is best
5) north bridge and south bridge are what connect the CPU to the rest of the system....
the north bridge is the one closest the to cpu and generally has a heat sink and or fan. this is responsible for controlling access to your ram, giving instrcutions from the cpu to other hardware in your system.
the southbridge is lower down the motherboard......usually to the right of the pci slots....this is generally uncooled and appears as large square chip. this usually has the task of controlling any onboard LAN, USB ports, fire wire etc, and if you have on board sound (ie no sound card in a pci slot) then the southbridge usually has a audio codec built in.
6) flashing a card, i guess u mean GFX? any way your graphics card will have a bios just like a motherboard, this contains the basic settings (ie memory and core speeds etc) and most importantly the cards identity.
for instance i can buy a 9800 non pro..........download a 9800pro bios and i think then you make a flash disk or download a special flash software (not sure never try'd) if i flash the 9800pro bios to the 9800non pro then if it is successful the card will now think it is a 9800pro and boot up with the pros settings and identity every time you turn on...this is risky if the components on the card are not capable tho. for instance an 9800pro may have 2.2 ns ram, but the 9800 non pro may have 2.8ns ram as its meant to be a slower derivative, by calculation 2.8ns is not capable of speeds that 2.2 can muster....so you may end up killing something after a while.
also a 9800pro runs at 380mhz on the core........only chips from the manufacture that are stable at this speed are used....chips that are made but can only manage say 360mhz will be put to use in a slower card like the 9800non pro so i'd be carefull when flashing!.
hope that helps
