PowerMac G4 MDD unstable after bus speed mod

I haven't checked the Vcore, but the chips are 7455A. It should be at the stock setting. I'm a bit unsure as to why it would need a boost if it's being run as designed; this card was originally sold with a 166MHz-bus speed system. The issue is between the Memory Controller and RAM.
Sorry, I understood that you were using the 867 set to 1ghz. Lost in translation 😅

Ah no worries. Funnily enough, my Dual 867 CPU is really a Dual 933.
