Reboots or shut downs while OC. What could be the cause?

post #1 of 3
Thread Starter 
I have at 1055T thats happy to boot at 4050mhz with 1.425v on the core and 1.375v on the CPU-NB. Ram runs at 1600mhz(6-8-6-20-24-1T @1.6v). Temps are not an issue with the CPU @ 35oC and NB @ 47oC when running IBT on Max.. My question. When I increase the CPU to 4.2Ghz, and increase the CPU voltage I can boot into WIn7. Run IBT and either I get a reboot, power down or Linpack.exe has stopped working. Any ideas? Increasing the voltage of the CPU to 1.55v doesn't help. Temps are okay as I have water cooling.

I had a similar problem when overclocked above 4.0 and memory at cas 6 at 1600. Stepped down to cas 7 at 1333 and it stopped. hope this helps

Im not really too sure, but is it set to automatically scale your ram speed with your cpu speed? So overclocking your processor could be putting it past what it can handle without errors. Other than that, Im not really sure.
