With legacy via's bios no problem with this module. After changing to 256Mb 8-chips single-sided module the problem gone away. 512Mb 16-chips dual-sided module works also. 128mb module's chips have following label: KINGMAX KDL668P4LA-50 I used linuxbios image r2611 taken from http://qa.linuxbios.org/overview.php

What Epia-M do you have?
I think the Epia-MII6000e does only support DDR266 (PC2100). Maybe LinuxBIOS clocks the memory too high?

I've always used DDR400 (PC3200) on my mii6000e without problems. I think this problem is due to either broken RAM setup in LB or broken RAM module. (Maybe the SPD EEPROM is lying? Can that be checked easily?)

looks like VIA EPIA ME6000G, not MII

LinuxBIOS clocks the memory too high? 256mb and 512mb ddr400 modules works just fine

maybe, but legacy bios works fine with memory timings from SPD

Can you provide north bridge dumps with the bad ram module from both linuxbios (after dram setup, before jumping to the ram part) and legacy bios?
Also, can you dump the spdrom?
There are functions in LinuxBIOS to do this.
