I have a Pentium D 920 which is supported by the motherboard
1GB Veritech two-sided(8chips each side- total of 16chips)
It says in the overview
Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
" Double-sided DIMMs with x16 organization are not supported"
What does it mean by x16 organization?
My memory has two sides and has 16 chips, is the overview referring to the memory I have. And so, does that mean I will not be able to used my 1GB two-sided sixteen-chipped memory in this motherboard?
Most likely, but trying it out won't hurt anything. Your link didn't work. If the Intel board is an older chipset, I would get another brand with a newer chipset if possible. The g31 or g41 boards often work with older p4 cpus, and give you plenty of upgrade potential, if your ram is pc5300 or pc6400 ddr2.
