Default X79 motherboard won't boot when RAM slots are fully populated

Can't figure out the issue. If I populate 6 DIMMs (24GB), then the system will boot. But I add the last two and the system does't post. I tried increasing the system agent (memory controller) voltage to 1.1V, reducing memory settings to 1333MHz 10-10-10-28 and increasing memory voltage to 1.55V but nothing helps. Any suggestions on what I should do? Might the memory not be compatible?

3930K C2 (stock speeds)
Intel DX79SI (newest BIOS)
8x4GB Corsair Vengeance (CMZ16GX3M4A1600C9B)
Corsair HX750

You have the incorrect memory for that system, the correct part would be listed on this web page for Quad channel Sets.
