I'm having similar issue with this cpu. X4 860 k amd Athlon fm2+ on an Msi a78m-e35 board. Initially worked out of box but after trying to update board bios now doesn't initialize graphics card. Tried 3 different cards, none initializing. Reset cmos not working. This cpu has no graphics integrated. Replaced board with Msi a78m-e45 and same issue right out of the box. Previously tested ddr3 ram with memtest and no errors.put in an older amd dual core 7300 apu and comes right on. Even when was able to boot with the x4 860k I was getting constant bsod...dpc watchdog violation, Irq not less or equal, memory mgmt. all seem to point to memory but ram seems fine. Put in new ram and same issue. This cpu does control memory so that's the issue. I'm going to just take it back, could just be a bad cpu but I don't think I like these CPUs with no integrated graphics as no fallback if doesn't work with a graphics card. The fm2 7300 seems fine and I would say actually seems faster and so far no bsod. Anyone else having issues with this cpu or know any fix?
