e8400 on eVGA 780i voltage help!

post #1 of 3
Thread Starter 
OK, I'm over my friend's house overclocking his build again, a build that I had running stable at 1.368vcore, but I don't remember exactly what the MCP, SPP, and VTT voltages are for and what values are safe for them. I'm guessing that SPP is the southbridge, and the MCP is the NB, but what is VTT? Give me some numbers for each so I don't fry this board by accident. This is for a 4.0ghz overclock (446fsb), so give me suggestions!

MCP is NB and SPP is SB if my memory serves me correctly.

VTT is also refers to the termination voltage, used to terminate data lines between the MCH and CPU.

Too much VTT can destroy your 45nm Proc ill find the volts and edit my post in a minute.

Edit: From what i read dont go over 1.4v on VTT

Voltages from Robilar's Post

Voltages:

Set Memory to 2.1 V (whcih is the default for my OCZ ram)

CPU Voltage: (for the e8400 i dont recommend going over 1.3625 shouldnt need it anyways unlees watercooling or otherwise)

For 3.2 I set it to: 1.3625

For 3.6 I set it to: 1.48125

(These will vary based on your chips' VID and stepping)

Other voltages:

(All set manually do not leave them on auto)

CPU FSB: 1.4v

Memory: To whatever your ram needs

Nforce SPP: 1.4v

Nforce MCP: 1.525v

HT Nforce SPP: 1.25V
