post #61481 of 68054
I really don't care about the ports.
What matters more is performance and stability.
The Aura is rated at DDR3 2133 while the fz is rated at 2400.
Can the Aura also overclock the memory to 2400?
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?

Thank you.
Cheers

The Formula Z gives more SATA and USB ports, but no M2 and no USB 3.1
The Formula Z makes overclocking past 4.5Ghz easier.

IMHO, the Formula Z is wasted money, as feature wise the Aura is better and number of ports on any 970 motherboard is more than enough. With 10 euros you can even buy a USB hub and add 4 more USB ports.

had a very crappy fx 8350 would not be stable at 4.5ghz and 1.5v so i trade it for a fx 8320, so far so good, happy at 225x20.5 (4.6ghz) with in bios 1.337v load 1.368v mem stock is 1600mhz 9-9-24 overclocked to 1800 9-10-27 a lot better then my 8350

Have you tried to look at the stamped batch number?

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:

http://www.overclockers.com/asus-970-pro-gaming-aura-motherboard-review/

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:

http://www.overclock.net/t/1318995/official-fx-8320-fx-8350-vishera-owners-club/61450#post_25371355

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:

http://www.overclockers.com/asus-970-pro-gaming-aura-motherboard-review/

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.

Save the cash, get the Aura and be happy.

the CVF-Z is only for people who want the absolute most out of the FX chips, the Aura has good power delivery and good heatsinks, it'll push past 4.5 easy.

Any 970 board (with decent power delivery, Aura/970 Gaming/Etc) will be fine unless you are going to shoot for 3 or 4 way CF/SLI.

HT wont make much if any difference on the 970 as it is already relatively balanced from a bandwidth perspective.

Overclocking the HT on a very high end CF/SLI setup on a 990FX board can show gains because the 990FX has more PCIe bandwidth than HT bandwidth at stock speeds and overclocking the NB to CPU link relieves some of that limitation.

Real question is, (rather, QUESTIONS) are you willing to do what most people felt challenging to tame these chips?

Cooling - Water or 240mm AIO
PSU - a good one.
Time and Patience - you will need ample.
Knowledge - you need to listen here.

The Aura has been tested by one of the experienced members here and showed some promise.

The CHVFZ is a proven one.

2400MHz RAM will need a good chip and a capable RAM kit.

HT Link Overclocking is unnecessary unless you really need it ( 4 GPUs ).
