I think that this EVGA board must automatically overvolt the RAM at least .05 of a volt and that's why it's working at this setting for me, it might also explain why people are frying DIMMs running 2.4v, the actual voltage might me a lot higher.
disable any and all advanced cpu features like power management
SLI RAM setting is on expert/manual
I have all voltages set to auto other than the vcore and vdimm.
vcore voltage is at 1.46825 (my E6400 seems to take more voltage than others')
vdimm is at 2.15
memory timings are manually set to...
I guess I got lucky with my system, this is by far the best motherboard and RAM that I have ever used.
I have the latest chipset drivers for the mobo from nvida and the P26 BIOS from EVGA, P27 does not work with this setup.
