Memory FSB vs CPU FSB

Havent seen anybody ever specifically state it but I am wondering if there is any problem with running my CPU FSB faster than my RAM. As the eVGA 680i can unlink the two speeds I can set them independently. Currently I have both at 400MHz(times their respective multipliers).

The thing that raises my question is because most people say that If you want to get past 3.6GHZ on a E6600 you need to get something better than DDR2-800 memory.

Thanks for any input you guys have.
 
Yep yep I am for boobs too. Definitely need more boobs, bigger the better.


"They" are all talking about Intel boards that cannot "unlink" CPU and memory speeds, thats all. Its a fairly new board and with an Nvidia chipset that works completely different so a lot of people don't even know you can do that. (and guess what 9x 400FSB multiplies out to)

Now the real question is, can you increase the memory speed enough to make up for all the wait states and buffers that have to kick in because the CPU's internal L2 cache is running at FSB x 2 and now the memory is not.

OOPS scratch that above (its true but not what you asked) :eek:

You want to run CPU faster than ram, sure go for it, in that case its almost certain the increase in processing power will more, much more, make up for the mismatch in timing. Run the CPU as fast as you possibly can.





3.6 is pretty respectable OC, getting much higher will not be trivial and require top notch cooling. Frankly 9x 400 sync is probably going to be your best bet unless you water cool, and my PC6400 goes to about 850 before I have to loosen the timings, that gets you 9 x 425 = 3.825 and you can see at 5 4 4 12 it makes 944 with a 472 FSB and that gets you 9x 472 = 4.28 GHz and I am not sure but don't think the 680's will go that high reliably. So moral of story just buy good pc6400 (800Mhz) memory.

Yea I know 3.6 is good. I just wanted to see how high I can get it. So I just asked to make sure it wouldn't cause any problems.
