asus crosshair v formula help

post #1 of 5
Thread Starter 
hi, i just got this motherboard used, and placed a phenom ii 965 black edition processor in it. with g-skill sniper 1333 ddr3 ram, and tried to put both of my his iceq x turbo hd 6950's in crossfire x mode. and the motherboard would say overclock failed "NB overheating" making me go into bios. every setting is at factory settings on the motherboard. i tried each card individualy and everything worked fine. installed all the drivers and tried to do both cards once again. and same issue. northbridge over heating. so i decided to disable the northbridge sensor sence it didn't feel like it was even warm. finaly windows would boot up. then with in a few seconds my monitors would go into sleep mod or something. making me turn off the pc and pull the 2nd card. and reboot and everything worked fine again.

so my question is, what can be making the north bridge to over heat when i put a crossfire set up into it knowing this motherboard was designed for doing just that. i'm thinking it's a bad sensor sence nothing seems to feel hot to the touch. cpu hits maybe 47c when idle and mobo is only getting to 36-37 idle.

things i've tried:
updating bios for the mobo
placing second gpu in different pci-e slots
disabling heat sensor for nb (thinking it's a sensor problem)
reinstalling windows and drivers (twice)

can someone please help on what this problem might be caused from?

have you posted on the ROG site,,,the first crosshair v formula had a lot of issues,,i own one,,,,,did you check to see if the north bridge heatsink is sitting properly,,,be carefull with the factory settings on that board,,,mine would disable the LAN everytime i went to default bios settings,,,

no i haven't checked the heatsink on the nb yet. only because i can't figure out exactly where it is. i'm thinking it's the part that has the R.O.G emblem on it next to the pci-e slots. also to mention sence i finaly got the curage to try gaming on this board for the first time. it shut down about 2-3min into the game. and once started it back up it said overclocking failed again making me go into bios. and how would i know if this was one of the first mobo's of this series? model #'s or something?
