Fast isn't always fastest

If there's one thing that the Speedy3D team understand all to well, it's that fast doesn't always mean fastest. AMD have in the past been limited because their CPUs ran @ 200Mhz (Dual 100Mhz) FSB, but only for a small portion of the board. The rest of the system was thus forced into a limited 100Mhz state as overclocking the bus would mean the DDR 100Mhz (200Mhz) would double up and cause problems with the CPU.

Lets face it, 200Mhz is pushing it but go any faster and stability instantly becomes a very real issue, even with a tiny 1Mhz push you might see the odd problem, such is the thin thread that Athlons tend to hang by. This raises the question, what's the point in a 133Mhz FSB if you can't use it? We've had Slot-A Asus boards (K7M) before that could be clocked to 150Mhz, yet we could never take advantage of that above 105Mhz FSB.

The good news is that the 133Mhz BUS in the KX Via design is a lot more stable than crude board manipulations of the past. The whole board is based around 133Mhz and that includes memory, CPU and the AGP port. So the fact remains that you're not likely to make full use of the 133FSB just yet, but that doesn't mean to say it won't work.

Stable and Sturdy

If you own a higher end CPU like a 700Mhz then you could use one of the Overclocking boards (FreeSpeedPro) to underclock the Mhz and then overclock the FSB to 133Mhz until you get the right Speed for your CPU showing up on boot. This will dramatically increase your systems performance levels and shouldn't require any change to the voltage.
