Hi I am think about buying a processor as part of this system: http://forums.bit-tech.net/showthread.php?p=1687415#post1687415 It the Intel Core 2 Duo E8400 LGA775 'Wolfdale' 3.00GHz (1333FSB): http://www.overclockers.co.uk/showproduct.php?prodid=CP-192-IN However, I do not understand the FSB speed of 1333 MHz. There do not seem to be many memory modules out there that run at his speed, e.g.: http://www.ebuyer.com/product/130430 and they cost more than the processor! I looked into getting the next FSB down. It seems that there is a huge jump! The next lowest Core 2 Duo FSB speed was 800 MHz. I am confused. I plan to get a dual core because most games do not support quad yet. Would I be better off getting a quad core and slower memory? Please help! I am lost Thanks
Depends on your budget, get quad if you can afford it. If you need DDR2, one of the best performance/cost memory is the OCZ Reaper 9200 at £90 for 2gb: http://www.overclock.co.uk/product/...eaper-HPC-Edition-Dual-Channel--Kit_4065.html As for DDR3, expect to pay more but it has started to come down a lot: http://www.aria.co.uk/Products/Comp...B+PC3-10666+Platinum+(2x1GB)+?productId=27959
The processor FSB (1333) is Quad Pumped. The "real" front side bus is only running at 333MHz. RAM speeds are Double Pumped. So to run at a FSB of 1333 (333) you need RAM that is capable of 666MHz operation. You can go 800 or 1066 RAM if you need the headroom for overclocking.
See this thread (though it only repeats what badders said). The processor runs stock, 333MHz system bus x 9 multiplier = 3GHz, DDR2-667 OK (just). To overclock up to 3.6GHz you'd use up to 400MHz system bus and need DDR2-800 To go any higher you'd need DDR2-1066
As that says. But, that is if you don't want to buy enthusiast memory. Ballistix, for instance, are amazing overclockers, plenty for any processor out there.
Should add that with faster memory fitted an Intel board will auto-set a memory multiplier higher than 1:1 to suit the memory fitted, so DDR2-800 will get 333 x 2.4 = 799. A small advantage in real life, but it may give better benchmarks. When overclocking the system bus (especially by a large amount) you need to remember to turn that multiplier down.
