could doing a bios update make a cpu compatible?

So i have 2 LGA 755 cpus and a mobo i want them in. One is a Pentium 4 @ 3.6GHz with hyper threading, another is a Pentium D @ 3.4Ghz. Obviously the First one is better, like i said they both are LGA 755, but i put the Pentium 4 in the mobo i want to use and it said "cpu not supported" could a bios update make it supported, or is this a voltage thing so like it would never be supported?

Maybe, but only if there are no physical incompatibilities and the manufacturer of the motherboard created a new BIOS that could support the different CPU.

 

If there are any physical differences or the manufacturer never made a new BIOS, it will not work.

Wait wait wait, a P4 with Hyper-Threading? O.o

Core 2 required a voltage regulator on the motherboard that was not needed for the Pentium D line of processors, all early 775 socket motherboards do not have this VR and there are also several "generations" of 775.

yeah ikr, it has it xD

its a single core, but in task manager it shows 2 cores, so i googled it and it actually has hyper threading lol

I'd go with the Pentium D actually. It's literally two non-HT P4's stuck together, so two real cores will be better then one with HT.

but the pentium D is a single core

It's a hackjob dual core. Basically a pair of dies stuck together. On Presler (65nm) they just put 2 cedar mill dies on 1 chip.

Yep. Hyperthreading was made in mind as the pipeline was sooo long (31 stages, about 3x longer than core) so HT came along to make use of the massive amount of resource waste.

 

So i have 2 LGA 755 cpus and a mobo i want them in. One is a Pentium 4 @ 3.6GHz with hyper threading, another is a Pentium D @ 3.4Ghz. Obviously the First one is better, like i said they both are LGA 755, but i put the Pentium 4 in the mobo i want to use and it said "cpu not supported" could a bios update make it supported, or is this a voltage thing so like it would never be supported?

What chipset is the board?
