Thanks for the suggestion, but when I read the spec, these look
awfully like the Kingston ValueRam (or infineon &c equivalent), the
same DIMMS which recent-ish socket939 BIOSes downgrade to DDR333.

There's a line about 2/3rds of the way down the URL which says

    # 1GB PC3200 CL3 18-chip 64x8 ECC DDR400 DIMM.

The "18-chip" is a dead give-away that these DIMMS are double-sided,
9 chips per side.
