If anyone working on the 440 has time, can you check the output of your spd data and see if there's any non-00 or 0xff data in 0x7e and 0x7f (aka 126/127)? This is part of the Intel SDRAM SPD standard, but not officially part of JEDECs. The 3 dimms I've checked all support it, along with one Uwe used (from a minicom.cap sent to the list), but I'm curious how many don't, and if they don't what values they return. This is by far the easiest way to set up a lot of the northbridge stuff by spd, but if there are lots of dimms out there NOT supporting it, I'll see if there's another way.

am i looking at this right?
Row 0x70, and count in hex.
The values at 0x7e & 0x7f respectively are; 0x64 & 0xa4?
Looking at the other 2 sticks of sdram I have:
0x64, 0xf6 0x64, 0xf7
(0x64, 0xff are all on my Mushkin in my S1832DL)
Yep, exactly right, thanks! I think I'll work using these bits for now, and if it turns out they don't work I'll switch to some other method.
