problem sticking in a tick of RAM

[rookie1010]

Helo

I have got a gigabyte 81875 ultra which originally had one stick of crucial 512 MB RAM.

I bought two sticks of kingston 512 MB RAM and tried to place them in any of the remaining (6-1) free slots. i could nto get all three sticks in at the same time.

i managed to fit two sticks of RAM in the 1st and 4th slot (orange slots). for some reason i can not fit any RAM in the purple slots.
RAMs wont go into slots 2,3, 5 & 6 completely(purple slots). can you guys help me out

If thats an intel motherboard the other color slots may be DDR2, which is a larger slot then DDR and will only work with DDR2 Memory. Therefore you could possible break or damage your motherboard by forcing them in.

In short, they won't fit. Don't try.

thanks for the reply

no, actually the mobo does not support DDR2,

i think the memory modules for some reason just wont go in. at soem point it went in a bit, and for 3 sticks of 512 MB RAM in(one not in properly), it read 768 MB, the next time i had the improper stick of RAM in, it woud not go into the memory test(bootup)

this is what the mobo manual says
􀁹 6 184-pin DDR DIMM sockets
􀁹 Supports Dual Channel DDR400/DDR333/DDR266 DIMM
􀁹 Supports 128MB/256MB/512MB/1GB unbuffered DRAM
􀁹 Supports up to 4GB DRAM (Max)
􀁹 Supports only 2.5V DDR DIMM
􀁹 Supports 64bit ECC type DRAM integrity mode
