Can you mix 2100 and 2700 DDR memory

[blackrain]

The specs on the abit site say:

Memory
- Four 184-pin DIMM sockets (Un-buffered Non-ECC DIMM)
- Supports Dual DDR 400/333/266 (Max. 4GB)

Its not clear to me whether I can mix 2100 and 2700 DDR. I have a 2100 memory stick in there right now and want to add ram. Can I add 2700 (or even others that are not 2100)?

Yes you can, but all your memories will run at 2100 speed.

Thanks...by the way, i'm confused about 2100/2700/3200.....5400 (speed), etc versus abit's description in terms of 400/333/266 Can someone explain how's abit's description relates to speed. Can I get memory with any DDR speed (DDR 5400 for example)? And then there's DDR2...does my board supoport DDR2?

Things used to be so easy with EDO...even my first pentium 4 just had DDR 2100...this is my first time upgrading to a relatively sophisticated (yet already obsolete) system in many years and i'm not familiar with all the new memory.

2100 = 266mhz
2700 = 333mhz
3200 = 400mhz

so my machine can't go higher than 3200...is there a big difference between 5400 and 3200?

DDR above 400 will work on your board, there is just no official spec for it, so no motherboard will say it supports higher than PC3200. Anything higher that 3200 is for overclocking anyway.

DDR-2 will not work. It has 240pins vs. DDR's 184 pins, and you wouldn't want it anyway, because it has higher latencies, and AMD doesn't benifit much from higher bandwidth anyway.
