The FSB for this cpu has a theoretical bandwidth of 8.512gbs (FSB/ QDR 1066) but you wont see nothing but a fraction of that all thanks to the mem controller and the ram. The only ram tech out there that can saturate is XDR 1&2 and GDDR5 but that will never be adapted to the 775 or either of the 1366 or 1156. Only once was QDR (FSB) ever had a ram that could at some expense provided equal bandwidth and that was with the old RDRAM on the socket 423 and 478 (850i) at 100mhz (QDR 400mhz) with the ram running at 400mhz (PC-800-RDRAM thus 3.2gbs for both ram and cpu. Latencies ruined that to only 2.7gbs before the controller at 45ns. So that is one reason why intel has moved to the 1156 and 1366 sockets and dealt with the controller issue while running the mem at a higher clock thus more bandwidth. There is tones more but that will take you some time to figure out so QDR can get 3.2gbs for every 100mhz before every thing ruins the party. If inquired this to figure out some way to figure out some way to get better performance while not nuking your cpu there is a few tricks. One is lower timings on the ram and running it a higher clocks ( band aid solution) but it is not recommended for laptops. One now knows why AMD went with the integrated mem controller so early on and is one reason more why consoles are difficult to emulate and perform as well as they do.

PS sorry for the long post. :sleep:

What socket, board, cpu, ram plus timings, and finally what FSB or HT?

intel model "T9900" 3Ghz 1066FSB socket P

Reply to alexanderltorrez

its a dual core but i just need to know how many bites and bytes a second it can push

Reply to alexanderltorrez

per core,,common sense will tell me how much for both cores combined,,,i have 4 gigs of ddr3 with the cpu
