O.o... now i understand...
y u recommend beginner to try 333MHz?? i thought E6600 with 266MHz is easier for beginner to to start with since u say very ez to reach 3GHz
with that we come to the problem of FSB:RAM ratio... that shows the ratio between the FSB clock and RAM clock... these are real clock (or base clock as i ve said earlier, the proper term should be "real" instead) we re talking abt here...
for any Intel CPU still with FSB (ie pre Nehalem CPU), the optimal ratio is 1:1...
first of all we need to find the real clock... u already know how to find the real clock of FSB... how abt RAM???
the RAM that we re using now are Double Data Rate (DDR) SDRAM... DDR means that 2 pieces of data is transmitted in 1 clock cycle... so for DDR2 667MHz, the real clock is 667/2=333MHz...
so for fab's system, E7500 (1066MHz FSB) with DDR2 667MHz... the ratio is 266:333 = 2:3... and thus the FSB is the bottleneck here!!! since the FSB cannot send data as fast as the RAM can receive and vice versa...
thus to eliminate this bottleneck, and thus achieving a 1:1 ratio, we ve 2 options: a) drop the RAM to run at 533MHz instead, or b) raise the FSB to 333MHz instead...
so that's the reason y i suggested oc to 333MHz...

moreover, CPU is usually easier to OC than RAM, especially when u re using ValueRAM...
for comparison, my rig at home, which is E6550 (1333MHz FSB) and DDR2 800MHz is currently running @ 429MHz (real clock) for both the RAM and CPU... so my real FSB has jumped almost 100MHz, and real RAM clock jumped 29MHz from default setting... gonna try 440MHz when i go back...

well i had to miss those fun though

probably i'll upgrade the RAM to 4GB and buy 1 tera hard disk after this and then, thats it. after that just buy new pc.
well , ur choice...
happy assembling...

Added on November 5, 2009, 9:57 pmoh yes, and for beginners, 1:1 ratio is wat u should be aiming for first...
if u get a stable system while maintaining at nice temperature, then u proceed to go higher...
