aren't the icx temperatures from external probes, rather than the internal temperature of the memory?
That is the only explanation, only the ftw3 series 3080 have sensors as far as i know and that is a good thing, seeing the temperature helps me to push it higher, well the memory is already at 1235mhz and I already tried 1500mhz and it gives 103mhs and it worked without a problem, will leave at 1235mhz, 100mhs is good already.
