DFI UT X58-T3EH8 continued - Part 2

[pangingIII]

i just got a replacement board (one lan port not working on the old board). after a quick few tests of new board with all the old hardware i noticed that the chipset on the motherboard can affect quite a bit for VTT and IOH, my new board requires quite less VTT and IOH than the old one.
anyone experience this?


CPU VTT 1.21 (bios),
on the old board i needed to use at least 1.34-1.36 for 12GB RAM, uncore 18x and 1T...







IOH 1.13,
i would need to use 1.25+ for the old board or it would cause hang up at bios...
