I presume you're using CM74SD2048RLP-2700/S DIMMs? (Corsair/Samsung 2GB
ECC Reg'd.) 
More importantly, which BIOS version? You have to run the 2.03 BIOS on 
the K8SPro if you're running 16GB. Make sure that ccNUMA support is off
in the BIOS as well - this was a never-ending source of fun on both the
S2882 and S4882's. I can't tell you exactly why, but having ccNUMA on
with the S4882 and S288x's is a never-ending font of panic()s. But the
2.01 and 2.02 BIOSes on the S2882 are exceptionally miserable.
At least it's not an S4882 1.02:
"DDR 400MHz Memmory Detected"
