SLI broadcast aperture (enable or disable)

[wellnix]

Does anyone have a clue about this feature on the P5N32-SLI premium mobo.

Also: SLI Ready Memory
Limit CPUID MaxVal
Enhanced C1 (C1E)
Enhanced Intel Speedstep Tech
LDT Frequency

When they're enabled, pc won't boot.
All have to be disabled to boot up.

Any clues for the correct config?

SLI broadcast aperture: According to mot sources, this is if you use 2 different graphics cards for SLI, but NVIDIA says:

SLI Broadcast Aperture should always be set to "on" or "auto" when the choice is offered in the system BIOS. Some motherboards enable this feature automatically and some do not. The bottom line is that, when enabled, this feature improves SLI communication and can provide a performance benefit in many gaming applications.

So if you have 2 different cards, you should enable it, if not, try to enable it and use 3DMark or a game benchmark to compare the resultes w/ disabled.

SLI Ready memory: Has nothing to do w/ SLI except the name and that it was invented by NVIDIA. You need special SLI ready memory modules to activate this. SLI ready memory is something like a memory w/ a better SPD, which has timings stored for non-standard clock-frequencies.

Enhanced C1 (C1E): Enable this for powersaving when the CPU is idle. Should be disabled for overclocking.

Enhanced Intel Speedstep Tech: technology to reduce CPU clock and voltage when idle. Should be disabled for overclocking.

LDT Frequency: sets the frequency of the LDT (HyperTransport) bus.
