I have an Asus M3A78-EMH HDMI mobo, and I've tried to stick a AMD Phenom II X2 550 cpu in, but it's not recognised and keeps giving me BSOD. I already have the latest bios. Can anyone tweak the bios, pretty please? Edit: I believe similar bios can help in this quest? FYI - M3A78-EMH HDMI mobo has 780G chipset. M3A78 PRO and M3A78-EM also have 780G and support the Phenom II cpu. Edit2: I found a thread where someone tried to use the PRO and it didn't work, so the EM might be the best candidate? Also I am waiting for the posting rights to that forum so I can post to another thread.
