Strange 4.8Ghz cut off FX8370

[suckmyoverclock]

So i got my fx 8370 to 4.7ghz on 1.35 v using hyper 212 evo. however, i go to 4.8, and a core fails. put up the voltage a notch. still fails. another? fails again. 1.44 didn't even work. so i put the bus speed back from 240 to 239, and the voltage back to 1.35, and completely stable at 60c core and 68 socket. For hours on end. So, there seems to be a 4.8ghz cut off, and I cannot understand why. By the way, by PSU is a corsair cs750m, and my mobo is a crosshair-v formula z.

Welcome!

FSB at 240 is pretty good. You are likely hitting your limit there.... If you can, reduce the FSB back to 200MHz and see what your overclocking shows with just a multiplier change (and voltage). Your max overclock will be a combination of a FSB increase and multiplier increase. with voltage increases, maybe try to land on something more like 204 FSB with a multiplier of 24 or 24.5 (to get near 5.0GHz).

Reference material including your MB and CPU (they did 5.4GHz with FSB @ 236 and multiplier @ 23) => http://www.techpowerup.com/forums/threads/amd-fx-8370-125w-at-crosshair-v-formula-old-one-no-z.205780/

Thanks for the early and helpful reply. i'll get into the bios now and try putting down that FSB. lol, 5.0ghz with the 212 evo would be sweet. it'll be fun to see what i get when i do my custom loop

Thanks a lot. Straight to 4.9, and going strong and stable.

You are welcome! Let us know where you land on the final overclock settings.

I got to just under 5... needed more volts, but my cooler cannot handle them. I'm already getting parts for a custom loop together Also, thanks for the warm welcome to the site. I definatly am going to be using this more 😛
