Thanks for explanation! I haven't known about this subtle difference. I've always mistaken thinking that they all use SMP.
I've picked inside and it looks like 775XFire-VSTA bios has init code for Conroe but not for Wolfdale. Maybe I'll try to add Wolfdale support later.
Asus p5gd1-vm bios was built on much older source base. ASUS engineers added something but anyway it lacks lots of init procedure for Conroe.
I wanted to say Core 2 Duo oops, Core 2 Quad needs SMP.
I tried Wolfdale with ASRock 775xfire-vsta bios and it was awful, but good to hear it have code for Conroe 😀
I doubt Asus p5gd1-vm have any code for Core 2 ,even version from 2004 acts same with them. This is not only non-core 2 bios that do same thing, ASRock 775s61 and ECS rc410-m2 can initialize Core 2 as well!
That would be good to have Wolfdale support in 775xfire-vsta, that bios (believe or not) "works" on ABit AA8, i tried it for fun and it works but with problems, same with p5gd1-vm bios but less useful 🤣. With that mod i should be able to use E6500K on it.
BTW, can be overclocking options unhidden in Asus p5gd1-vm? I want to try something 😁
Yes, reading your answer I had in mind exactly dual-core CPU-s. Anyway I really don't understand how it can be. The both families have two cores inside one package. So almost all signals are the same. But one works, another doesn't (even a little bit, no posts at all). It is not about supporting two CPU sockets on a mainboard where a chipset really must support SMP.
On modern motherboards a "foreign" bios almost always guarantees serious or minor problems (not detecting devices, resource conflicts, wrong sensor readings and so on) .
What about Wolfdale. Any unpredictable hardware problem (wire, voltage, signal) may make system get unstable. Asus P5LD2 rev.1 wasn't meant for Core 2, but using a pin-mod the Conroe can work there. From the other side the same pin-mod doesn't make the Wolfdale run on it even if the bios supports it (the system stops at some early bios procedures).
Asus p5gd1-vm. If some options are hidden maybe they can become visible with help of AmiBCP tool. But I haven't tried this method personally. Sometimes options get visible if some conditions are asserted: a "CPU ratio" option may get visible if a CPU has the unlocked ratio.
