Below you can see the difference between the 400 & 401 fsb and how the timings on the NB become more relaxed. Then you can see the performance gain as you move up on the FSB. All of these benchmarks were made with my P5B Deluxe.

400 x 8 1:1 @ 1600 FSB / Mem was @ 800Mhz Vcore 1.375 @ 3.2 - Idle-34c Load-54 (orthos)
SiSoftware - MEM = 7259/7285
SiSoftware - CPU = 29380/20477

PCmark05 - 7421

401 x 8 1:1 @ 1604 FSB / Mem was @ 802Mhz Vcore 1.375 @ 3.2 - Idle-34c Load-54 (orthos)
SiSoftware - MEM = 6761/6769
SiSoftware - CPU = 29463/20523

PCmark05 - 7380

425 x 8 1:1 @ 1700 FSB / Mem was @ 850Mhz Vcore 1.425 @ 3.4 - Idle-36c Load-58 (orthos)
SiSoftware - MEM = 7172/7196
SiSoftware - CPU = 31203/21777
PCmark05 - 7595

450 x 8 1:1 @ 1800 FSB / Mem was @ 900Mhz Vcore 1.55 @ 3.6 - Idle-40c Load-71 (orthos)
SiSoftware - MEM = 7365/7385
SiSoftware - CPU = 33188/22560
PCmark05 - 7893

475 x 7 1:1 @ 1900 FSB / Mem was @ 950Mhz Vcore 1.425 @ 3.3 - Idle-36c Load-58 (orthos)
SiSoftware - MEM = 7814/7828
SiSoftware - CPU = 30532/21296
PCmark05 - 8528
Hmmm... well I tried both 401Mhz and 410Mhz, both at 8x Multiplier and 7x Multiplier and my system would not post by jumping up past the bad zone either How much voltage should I give my North Bridge and FSB Termination voltage??... right now both are at Auto and I have no idea what they read... I dont want to go frying my chipset or anything by manually setting them to high. Just trying to rule things out.... perhaps I just hit my max
