Obviously it's not as simple as this but:

Depending on the binning process you may get a 3800X that boosts to 4.5ghz @ 1.45v for single core loads.

Someone has a 3700X that boosts to 4.4ghz @ 1.4v for single core loads.

If PBO+Auto OC is based on microcode/software limitations at X value for TDP, amperage, temperature, voltage, etc... wouldn't an improved PBO algorithm theoretically let the 3700X boost higher when all of those criteria have not been exceeded? And in this specific situation AMD theoretically (and also in practice 65w vs 105w TDP) allowed the 3800X to hit a much higher PPT, TDC, and EDC, (enabling PBO and auto OC "should" allow for a higher PPT, TDC, and EDC than a stock 3800X).

I thought this was everyone's initial take away from Hallocks infamous video about PBO and Ryzen 3000, and why everyone was ticked off that it essentially did nothing. Seriously though, what's the point of having a +200mhz auto OC option for PBO and only getting 25mhz when I'm not hitting any of the 3 PBO limitations. Sure not every processor is the same but this sounds more like microcode/software limitation than hardware.

Quote:
“this feature will not guarantee the higher boost clock on any number of cores. The frequency/cores/boost duration will still depend on the firmware-managed limits, even though those limits are higher than OEM when PBO has been enabled.”
A direct quote from AMD stating it's a firmware limitation

PBO changes was one of the things Hallock posted/talked about in the reddit post afaik, and it would be nice to see my pbo boost higher than 25mhz when my power/temp are well within limits (boosting to 4425 on 3700x @ 49c avg in single core tasks @ ~1.43v).

I also have the Corsair MP-600 1Tb, performance is poor in 4K, and I don't understand why.


I also tried the Aorus Gen4 1Tb, but more or less the same

Here is the CrystalMark of Corsair MP-600 1 TB






Here is the CrystalMark of Aorus Gen 4 1TB






Both have poor performance in 4K

101 MHz OK, but 102 MHz BLCK freezes

Physically, there is a generator on the board.
Another thing is that it does not work with 3xxx zen, and judging by the changelog, it will be included in 1.0.0.4

This is one of the reasons why I bought this particular board.

It turns out that I made a mistake in choosing a board ..

at all previous crosshair he was, and I was sure that there is here

Why did the asus do this?

Any of you guys 100% sure there's no dual BLCK on C8H/C8F at all?


Is the "feature going to be added with planned update" real info or speculation?

Lupo91 None of you have an ssd m2 pciex 4.0?

In case you can post a CrystalDiskMark ??

Thanks
