Question I3 540 H55M-D2H only boots to Windows with 4gb RAM

[Dororo00]

Hello I've encountered a problem while building an old computer that is using an I3 540 and an H55M-D2H from Gigabyte.
The system only boots to Windows successfully if you have less than 8GB of RAM in it, PC posts with +8gb but fails to boot into Windows, even though the motherboard seems absolutely OK with it, since it goes to BIOS no problem, just can't boot to Windows.
Tried to:
-Update BIOS
-Reseat CPU (checked for bent pins too, no bent pins)
-Swap Memory with this results:
2*2gb Ok
2*4gb POST Ok Shutdown/BSOD Windows
2*8gb POST Ok Shutdown/BSOD Windows

My bet here is that the IMC of the chip is damaged by age and it doesn't like to work with more memory but I could be completely wrong. I have an X3450 on the mail arriving but want to get some opinions cause if it's the motherboard I'm kind of screwed.
Any Ideas?

Update: tried with a Linux live usb same result, pc restarts

what speed and voltage are you running the ram at? The i3 can only run 1666MHz according to the motherboard spec sheet. I would guess this is a type-o and its only 1333Mhz.

H55 is listed to only officially support 2GB SS or 4GB DS modules. It turns out that H55 can support 4GB SS or 8GB DS modules but you need an i5/i7 to run them

What are the exact make and model of the ram sticks you are using.

Did you bring over an OS disk from another machine?

Really, your mention of trying this with Linux Live to the same result seems to indicate a hardware issue.

Are the sticks of RAM matching? If you use one of the 8GB sticks will it boot?

That makes sense, I got it for really cheap (like 20€ full machine with ssd hdd and a geforce 210) And planned to slap 8gb and a Xeon and call it a day for a really nice price, but the Xeon ended up not working so I just returned everything.
Anyway thanks everyone for your help
