Missing details in Datasheets for Family F

Hello there ,

i'm about to port a board to coreboot and miss some details in the datasheets.

the CPU(s) in question are a couple of 880 on socket 940 which report as

 

Family 0F(15), Model 21(33), Stepping 2, Microcode 0x4d

 

however, the Bios and Kernel Developer Guide for Family F does not even mention

Socket 940, in particular the DramTimingRegister Low, offset 0x88 [31:24]

is only declaring Sockets F, AM2, S1G1 and ASB1.

 

Beeing stuck on that part, i assume there are further differences because

this CPU Type is the last Fam_F using no DDR2 but DDR RAM.

 

Any hints, links and details are appredicated.
