Adrian's Rojak Pot - Where The Best In Technology Gather. Now talk about obscure! This is a BIOS entry in my DFI LanParty. It refers to the 123rd bug found in Dual Core Opteron and Athlon 64 X2 (socket 939)s.
BAsically, at low frequencies, DRAM data gets there too early and the processor hangs sinc data by passes the L2 cache and initiates an early DRAM read.. So if you select DISABLE, this avoids the bug which I need to do for my 3800+
There is also a feature called auto where the BIOS can query to see if it is a bad processor.
