Hit 1860 Linked and Synced at CAS8 (8-8-8-18 2T), with 1 Run of MemTest passed. CPU-Z Validated

Odd thing when I went back to a 1700 Linked and Synced at CAS7 (24/7 settings), NICs won't grab a DHCP address and won't communicate when I manually set an IP on my network. I tried uninstalling the devices, but that didn't seem to work either...checked for corruption, none found.

Anyone else had any problems with the NICs (nForce 9.64 drivers) not working?
