I'm quite confused with all the new dual-ddr and Mhz here and some busses over there. Please help me to clear some things up.

1. What type of CPUs from AMD supports the PC2100 and/or PC2700?

2. What kind of CPU support the PC3200?

3. What's all the fuzz about dual-ddr in combination with L1 or L2 cache?

question 1 and 2:
the motherboard determines what ram you can use. not the cpu.

question 3:

er, what? that doesnt make sense

Someone told me that it's no use in having dual-ddr unless the CPU has 512kb. Is that true or does all CPU support dual ddr?

someone is mixing you up. Anyway, dual channel does nothing for AMD cpu's except reduce latency a hair. Dual Channel does more for the P4, but the Granit Bay chipset that uses it isn't that great.

1. The 266MHz FSB AMD Athlons XP support PC2100 for default, while the 333MHz FSB use PC2700. But you also need a motherboard that can run PC2700 memory (KT333, KT400, nForce2) with 333MHz FSB CPUs.

2. None AMD CPUs... depends on your motherboard. nForce2 does support DDR400 which is PC3200.

3. Dual DDR has nothing to do with L1/L2 cache.

My dual-PSU PC is so powerfull that the neighbourhood dimms when I turn it on :eek:
