| 263019 | 2004-08-18 10:56:00 | a friend of mine recently made his own computer using: AMD Athlon XP 3200+ 400FSB Gigabyte GA-7VT600-P-L 512MB PC3200 DDR400 RAM as the basic parts. after loading windows XP and running CPUz it told him that the DRAM was at 200.9Mhz and that there was a FSB:DRAM 1:1 ratio. looking at the CPU section the FSB was at 200.9mhz. is this right? should it be 400mhz? Thanks |

| 263020 | 2004-08-18 10:57:00 | Don't AMD's run at twice the speed so 200 = 400? | Jester (13) | ||
| 263021 | 2004-08-18 11:03:00 | lol umm not too sure - the full speed for it is 2.2Ghz, it said 400mhz FSB on the box |

| 263022 | 2004-08-18 11:09:00 | From Extreme Tech (www.extremetech.com) However, AMD has pumped up the frontside bus clock rate from 166MHz to 200MHz, giving it an effective FSB speed of 400MHz (DDR). So, the actual fsb may be 200 but the resultant fsb is 400 |

| 263024 | 2004-08-18 11:35:00 | And the extra .9Mhz consider that some bonus power!! ;) | kiki (762) | ||
| 263025 | 2004-08-19 04:42:00 | Ok... this is the way i see it... I have a 1.8 P4... on a 400 FSB... My "actual" FSB is 100 Mhz and my multiplyer is 18... equaling 1.8 Ghz's The 400 Mhz's FSb come from the actual "Data thru-put", so with a steping factor of 4 (meaning with every clock-cycle its transfering 4 chunks of data rater than just one...) this pumps it up to 400... As far as i know... the steping factor with AMD is 2 and intel its 4... So with the "base" speed of your chip being 200Mhz's and 2 as the AMD steping factor... equaling 400Mhz's... also the way DDR ram is labled is by data-thru-put in bytes/sec so divide 3200 by 8 (DDR is 8 Bytes wide) and you get 400... |
