Thats what i mean with "Nodes" i lower the Compute Unit Setting in Bios and the CPU's are running much more stable at higher clocks.
8 Compute Units per CPU (16 Core) = max. 242 Mhz ref clock
6 Compute Units per CPU (12 Core) = max. 247 Mhz ref clock
4 Compute Units per CPU (8 Core) = max. 247...
i achived 247 mhz ref clock. 3952 MHZ for all Cores with 3 Nodes. With 4 Nodes the maximum is 242 MHZ ref clock. Its working with stock voltages. I have no options for setting the voltages higher. No ES Samples here :( The maximum of the NB is 240 x 10, but here also, the voltages limits...
For lowering the multi on NB, you have to choose "AUTO". It will automaticly go down to 9x when the ref clock is getting higher!
Here some of my system. At the moment i turned only 3 Nodes on. Tryin to find the maximum.
