can I combine pc2100 with pc3200 in dual channel?

[Holysmoke36]

I have a socket 939 asus board with sempron 3400+

I have 256 mb of pc3200 infineon in one slot. this board is dual channel.

I have 1 256 stick of ddr pc2100 from crucial and 1 stick of 512 ddr pc2100 from crucial.

will I mess up this system if I combine all this memory to get 1 gig?

it is a compaq computer that I bought for 150 dollars after rebate so I couldnt pass on that deal

Yes, but only running at the lower speed (DDR266/PC2100).

do I need to adjust anything is bios or will it be done automatically?

It *should* just work, unless you have manually changed the memory settings. Normally it will default to the speed of the slowest RAM that is detected.

it will underclock itself

You can combine them, but with 3 sticks, unless you have one of the Athlon XP motherboards that suports dual channel with 3 sticks, it won't run in dual channel.

I really dont care about speed, my main concern is hurting anything.

You wont hurt anything by using all of them.
