If some cores are hitting 99C, the CPU is throttling itself. You went for one hell of an OC there... if you're new, you'll do just fine on this forum
EDIT2: Also, you should take a look at this thread for some typical haswell voltages and speeds.
I have a follow up question, after reading some more posts about haswell overclocking: I have decreased the OC to 4.4 and that brought the heat down by about 5 degrees during the stress tests. That said, I have also read that during a stress test one would put the voltage in to "manual" mode vice "dynamic" or "automatic" (or whatever haswell does). I have not done that yet, so I imagine that could be contributing to the high heat. Is that an accurate assessment? Also, do you know if recommended temps are for individual cores or the whole chip?
I am having trouble finding all of the correct settings on my GB Z87X UD4 Bios. They might be names differently than other MOBO BIOSes. i.e. which voltage should I be adjusting and setting to manual, how do I do that, etc.? Anyway, if anyone has experience with this and can point me in the right direction that would be helpful. So far I have just been adjusting settings in the Windows interface provided by Gigabyte. Are there disadvantages to that?
