Pentium D 830 on an ASUS P5ND2-SLI

[BurritoJohn]

Hi, I once again need you help for an issue that is beyond my capacities.

I recently built a retro SLI setup and wanted to upgrade the CPU to a Pentium D 830. The motherboard is a ASUS P5ND2-SLI, and the CPU is listed as supported. It works, but the frequency is always maxed out, resulting in an idle temp of near 70°C which is the max temp listed by intel.

I assume that the Speedstep module is faulty or inexistant since I cannot see it in the BIOS and that the frequency is locked at its max.

The BIOS is an Award, attached to this post.

Could you please help me ?

Many thanks in advance !

Small update here:
- ThrottleStop says that my CPU is not supported...
- Undervolting the CPU from 1.4V to 1.0750V without stability issues solved my temp problem. The idle temperature is now at 45°C and under load goes up to 58°C.
- Speedstep is working with a Pentium 4 630 on the same motherboard. Maybe bypassing the CPU check could do the trick.
