Q: Why does my system crash or fail to POST when I try to use 256MB memory modules on Intel 815/815E based motherboards (SL6 /SE6 / SH6 / SA6R)?
A: The Intel 815 chipset (and also 815E) does not support 4x4, 8x4, 16x4 or any other x4 memory chips. A wide variety of errors is possible if you try to use double-sided 32MB chip modules or single-sided 16MB chip modules with this chipset, including system crashes or failures to POST.
