The other thing is hyper transport speed.
The fz is rated at a higher speed.
Can the Aura be overclocked to the same speed?
If it can't, does the difference give noticeable performance advantage?
The other thing is stability.
With an overclocked cpu, does the Aura throttle under load?
1) The main question is likely to be RAM compatibility. Some motherboards don't like some kits while others do. In both cases, the official FX memory controller, supports 1866Mhz. Anything above that, you need to overvolt the CPU-NB voltage too and it depends on the CPU's capability, not only the motherboard's. Here, the AURA runs 2400:
Instead of worrying about 2400, you can just buy 2133 with tighter timings. The end result is the same and the difference between 2400 and 2133 in FX is negligible anwyay.
2) I have already said what i think about HT in the previous post here:
I am not an overclocker guru though. If some of the gurus in this thread thinks otherwise, wait for his opinion. AFAIK HT overclocking is futile in FX and actually brings instability.
3) All motherboards throttle at some point. The question is which point and this depends on a per case scenario too. Your cooling and airflow are different than others. I can only repeat what i have seen reported in the forum. Up to 4.5Ghz, the Aura needs no cooling. Beyond that, i don't know. In the link i posted above, the Aura goes to 5Ghz:
But since every PC operates in different conditions, it's why i prefer being conservative and saying the "4.5Ghz without cooling". Beyond that, you may need cooling to avoid throttling, i don't know. Even higher ASUS, like Sabertooth and the CHV-Z need added cooling at some point. It's probable that they need it at 200Mhz later, but without having the 2 motherboards tested in the same condition neck to neck, i can't say. On paper, the CHV-Z is 8+2 phase, the AURA is 7+1. Then of course the amperage of the mosfets is another factor, i don't have such data. My lowly Gigabyte 970 UD3P, which 8+2 using doublers, passed IBT AVX at 4.5Ghz and i had started benching at 4.8 without throttling when i aborted. Others with the Rev2.0 can't go above 4.4. Motherboard behaviour isn't an exact science. It will also depend on your chip. Whether it's low leaker or high leaker.
Maybe one of the overclocker gurus can give you a better opinion on the matter. For me the high clocks are purely academic discussion. I just went there once just out of curiocity.Edited by Undervolter - 7/24/16 at 5:01am
