Newly installed 680i works fine running @ 10x multiplier. I am new to the board and am not familiar with all of the options available for OC'ing. My E6700 healthy OC limit is 3.5 ghz @ 1.52 v. I can go higher but need to up voltages and don't care to atm. Temps are 50C max under Orthos Blend, idle 35C-45C depending on Ambient.

I have tried a few times to boot up at 8x multiplier in order to increase the FSB speed. After a few failed boots ( wouldn't post ) I assumed I had a messed up board or I didn't know what I was doing in regards to settings. Since I am stable @ 3.5 ( Orthos Blend no erros after 24hrs ) I assume I am missing a valuable setting or combination of settings in order to boot at a lower multiplier to run at a higher fsb.

The following is a list of the current settings I have in bios based upon some OC advice from users and guides. I am not even sure if the 680i can run a lower multiplier in unlinked mode, I assumed it could. If any 680i owners can look at these settings and give me some hints or tips it would be greatly appreciated. Thnx in advance.


Limiters:

CPU Thermal Control - disabled
C1E Enhanced Halt State - disabled
Intel Speedstep - disabled
All Spread Spectrums - disabled
Execute Disabled bit - enabled
System Bios Cacheable - disabled
HPET - enabled

Nvidia GPU EX Enabled PCIe Auto = 125 Linkboost
Linkboost Enabled SPP - MCP Ref Clock Auto = Linkboost 250

10x Multiplier , 1400 FSB 3.5 ghz
HT multipliers 5x
Unlinked mode - memory @ 800 4-4-4-12 2T ( stable )

Voltages

CPU = 1.55 v ( bios reads 1.52 , lowest completely stable voltage at this speed for this chip )
CPU FSB = 1.5 v
mem = 2.15 v
nforce SPP = 1.5
nforce MCP = 1.5
HT nforce SPP - MCP = 1.55

If I change the multiplier to 8x it won't boot with the above settings in unlinked mode.
