Solved Question about Mobo/CPU Compatability Tags: CPUs Memory Last response: February 28, 2011 6:07 AM in CPUs Share trickynick February 27, 2011 7:10:48 PM I just recently bought an ASRock 870 Extreme3 and an AMD 955 BE CPU. I don't have any POST or video. Looked at http://www.asrock.com/mb/cpu.asp?Model=870%20Extreme3 and it doesn't show HDZ955FBGMBOX in the list of supported CPUs. Did a search on HDZ955FBK4DGM(BE) and a few places say it's the same as the first one. This true? These are the errors I'm getting: (see http://www.tomshardware.com/forum/287430-30-asrock-extr...) D1 - Perform keyboard controller BAT test. Check if waking up from power management suspend state. Save power-on CPUID value in scratch CMOS. D3 - If memory sizing module not executed, start memory refresh and do memory sizing in Bootblock code. Do additional chipset intialization. Re-enable CACHE. Verify that flat mode is enabled. C7 - Early CPU init Exit Are they compatable? What might be wrong with my system. Should I RMA the Mobo & RAM (per that thread) or should I also RMA the CPU? I'm getting really frustrated & getting more impatient as the days go by. it's been 2 weeks and my friend can't give me a straight answer. Can someone please help me?

It is very rare that CPU's are bad so RMA-ing the board and ram should be sufficient. trickynick February 27, 2011 10:35:07 PM So the CPU is compatible with the mobo even though has different part numbers? Or are they the same? I bought: HDZ955FBGMBOX Compatible Version: HDZ955FBK4DGM(BE) Are those the same thing? Is it compatible?
