Hi all,
I'm planning on getting an Intel Q6600 and was thinking about getting either 2GB or 4GB of RAM for my new system.
I'm trying to pick the right frequency of RAM to match the FSB or this CPU (1066mhz)...
Since the CPU is quad-pumped, I'm assuming the actual FSB is 1066mhz/4 = 266.5mhz.
This means that the frequency of the DDR2 RAM that I need is to be 266.5mhz*2 = 533mhz.
I'm assuming that this means I need RAM that has a clockspeed of 533mhz which is PC2-4200 RAM to sync the CPU and RAM FSB.. Correct?
I'm assuming that unless I overclock the CPU, I wouldn't get any performance gain from getting RAM that runs at higher frequencies..
I'm thinking about overclocking a little bit.. and I've calculated that the multiplier (I'm new to overlocking, so I know basically nothing about this stuff) for the CPU is x9... so if I get 667mhz RAM then it means I can theoretically overclock the CPU to 333.5mhz*9 = ~3ghz..
If I got 800mhz RAM it would work out at about 3.6ghz..
Now I know this isn't possible because of thermal and other issues. But the real problem is; should I get higher frequency RAM than 533mhz? If so, should I get 667mhz (which I can get with CAS timings of 3-3-3..) or 800mhz at 4-4-4..
Which would be the best to get for slight overclocking? Or bang for buck...
I don't mind spending extra if it will last me for a while, maybe a few years or something (Though DDR3 mainstream use seems to be just around the corner).
I also read somewhere else that in order to sync the CPU and RAM, the memory clock of the RAM would have to equal the actual FSB of the CPU.. this would mean that in order to sync the two, I would need RAM with a memory clock of 266mhz (which is 1066mhz DDR2 RAM).
Can someone advise which type of RAM to get, 'cos this is all wrapped way around my neck?
Thanks.
