P/I-XP6NP5 and single-sided SIMMs

I have a P/I-XP6NP5 Pentium Pro motherboard (Intel 440FX-based) and
I'm wondering whether it supports single-sided 64 MB SIMMs. The manual
states that it supports modules up to 64 MB, but says nothing about
single- versus double-sided ones.

I run two doublesided 128 meg SIMMs (24 chips each, with ECC) in an
i430HX board (GA-586HX, they also work in a GA-586DX and the trusty
P55T2P4), those work fine. Assuming the memory controller of the i440FX
is similar, 64 meg singlesided SIMMs with 8 chips should work. (I don't
think there are any EDO or FPM chips beyond 64 MBit, so it should be
possible to stay within the official limits of the i440FX.)

I've bought four single-sided 64 MB 8-chip modules, and they do indeed
work. Windows 2000 now runs smoothly on this 8-year-old computer.
