DFI 790FX-M2RS - Phenom II X6 Support

[Stealth2019]

Should i insert all modules from my original bios including my original AGESACPU.ROM and NCPUCODE.BIN?

Yes, all of them including main module d7ld706.BIN.

Ok...can you please tell me how do I remove system bios d7sd707.bin from LANPARTY DK 790FXB-M3H5 bios? 

You can see in the attachments the original file and how it looks with the modules cleared

I will not be at home until sunday afternoon as i am out of town but when i will arrive back i will attach the bios

Have a nice weekend!

OK. I've made "clean" BIOS with d7ld706.BIN module only, but raw code from 790FXB-M3H5.
Use it to make mods with original & modded modules.

I have downloaded your file and attached my original dfi modules to it. (without ncpucode.bin as it was already in the file)
The PC doesn't post, black screen, no power on self test beep.
Should i try to integrate my original ncpucode.bin ?
In the attached photo you will see the two files. The left one is based on your file and the right one is my original dfi bios

Other things i have tried:

Used your file as a base, update ncpucode.bin and agesacpu.rom from the gigabyte bios
Didn't post

Update agesa only
Didn't post 

Deleted Holes 0 to 3 from you file and putting back only 2 of them in the order i saw they were in my original bios (in your bios hole 0 was reversed with hole 1 in comparison with my original bios)
Here things gets even strange 
PC posted ok i was able to enter bios but when i exited bios i got black screen.
Cleared CMOS and try again...this time i let it enter windows 
PC locked up and was unresponsive.

I have done a little research
All the AM3 and AM2+ motherboards designed to support Phenom II X6 cpu have 8+2 phases for CPU power
My AM2 motherboard has only 4 phases
I think there is the problem, the CPU enters a fail safe mode when it detect it is not powered as expected

Hello Stealth2019

I'm working on a similar project on an older board, based on am2 platform.

I still searching info, but from what I learned in order to achieve to support Phenom x6 on older platform the bios modules to update are:
AGESA;NCPUID;MEMINIT
For the first 2 modules should be pretty easy to update, and we should not discouss about it.
The meminit module is the most complicated, as I can see analyzing it with an HEX editor I colud see that it contains some reference to agesa code and should be update, from what i understeand there are 2 ways to operate on it:
1: Change totally the meminit module with another one from other motherboard, better if it is from same vendor, mandatory about the ram types used (ddr2 or ddr3)
2: Modify the meminit module in order to include the agesa code, but for me and my skills is pretty hard and the risk of not working bios is high.
At this moment I'm stuck here, and need help in order to understand what to do with meminit module.
About the cpu phases 3+1 or 4 phase motherboard you are right, they are incompatible with 1100T and others X6 125w TDP, you should have bought a 95W x6 cpu.

What's CPU speed? How many cores are detected?

All the AM3 and AM2+ motherboards designed to support Phenom II X6 cpu have 8+2 phases for CPU power
My AM2 motherboard has only 4 phases

You can set 4 cores in msconfig with old CPU then install new one.
