Question about FSB / Memory frequency...
thegreat1 :
i’ve learned from my experience with AMD systems that you really can’t control the reference frequency. You’re limited to around 200mhz because the entire setup, including the NB, stays at that speed. If you try to adjust it slightly, the system might fail. There’s probably a tiny margin to push the frequency up to maybe 210-215, but that would be near the stability limit. Any changes will cause the whole system to overclock, leading to more heat and reduced stability. From what I understand, there’s no advantage to running a 1:1 like the one suggested—it keeps the same ratio, so it just scales the same way.
200 mhz IS a direct match, it's a quad-core processor... each core runs at 200. 200 times four equals 800... So when you scale it up to 250, you reach 1000, and so on. Overclocking the whole board is something I haven't heard before (I'm still learning). My clocker isn't great.
MSI k8n-neo v2.0
AMD Athlon 64 3000+ @2.4 ghz (240 fsb, 3 HT freq)
DDR400 RAM @ 2-2-2-6, 133 mhz (Wintech Ampo)
Original specs were 200 mhz but now it's 6-6-6-18
The chip runs stock at 2.0 ghz, so a 2.4 boost gives about 20-25% improvement. The stock HT is at 4, which means 200x4 equals 800 HT. (Idle around 38°C) 2.0 ghz
240x3 equals 720 HT. (Idle around 31°C) 2.4 ghz

It's not correct to set FSB higher than Dram. This could lead to significant issues.
