Let me congratulate you on getting a garbage board. I doubt that board will run the RAM bus at DDR533, and even if it could, I doubt DDR533 RAM would work at full speed on it. Your DDR400 RAM doesn't even seem to be working at full speed on it.
True sychronicity would be running the RAM at PC2100 speed in Dual Channel mode, but your board doesn't support Dual Channel mode. Your CPU FSB of 533 uses an actual clock rate of 133MHz, the same as DDR266 uses an actual clock rate of 133MHz. But the CPU uses a Quad Data Rate (4x transfers) bus, while the RAM uses a Double Data Rate (2x transfers) bus.
Fact is, there IS no good way to run the P4 2.4B in single channel mode. Since synchronous clocks provide the memory bus with 1/2 the bandwidth of the CPU bus, your best performance comes from running the RAM ASYCHRONOUSLY, trading off better bandwidth for worse memory controller performance.
I can't feel sorry for you, simply because you bought a VIA chipset board.
