Which memory for a 164LX motherboard?

[Steven Moix - Axianet.ch]

So, after the last topic I bought 4 128Mo PC100 ECC Unbuffered DIMMs (Micron
chips) for my PC164LX motherboard. They are double sided with 9 memory chips
on each side. But the problem is still there, the mobo doesn't want to boot
:(

So do you think that my mobo is really dead or is there something wrong with
the sticks I bought? Does the mobo support double sided memory sticks?

Thanks
Steven
