07/08/2019 6:33 PM (GMT) - Update on the bios issue on Crosshair VIII Hero motherboard ("the thing").
Earlier today I received a response to my inquiries from ASUS. The response was rather technical and I cannot go into the specifics of what exactly it involved.
However, it confirmed my suspicions of what actually has caused the seen anomalies. A long story short; a mistake has been made and it has affected the results of multiple reviewers, including my own. In my own case, I ended
up discarding my own affected multithreaded results alltogether, before even releasing them. I'm still angry because of a lot of my own and other peoples work went to waste because of it. But like I said, mistakes do happen.
In this case all of the evidence and known facts suggest that this was indeed a mistake, caused by an extremely tight schedule and miscommunication between several different parties. Infact, all of the facts I can personally verify
indicate that despite the rather suspicious way this mistake happened, there never was any malicous intent involved.
ASUS also provided me a new bios versions for both Crosshair VIII Hero and Formula boards, which correct the mistake made in newer than the AMD approved 0066 bios builds.
Based on my own testing done on the 3900X SKU, the CPU now meets its specification in terms of the allowed power consumption (same way, as the approved 0066 build did). The new build has currently not been validated, so
it will take some time until its changes get reflected to builds available to the larger audience.
What kind of effects will the fixed bioses have then?
Based on my own testing (
do note that silicon variation exists and that the sample size is one for 3900X):
- ~ 27W lower average power package power consumption (VDDCR_CPU & VDDCR_SoC, i.e. the main power rails)
- 7°C lower temperature (tDie, while using DeepCool Assassin II cooler)
- < 90MHz average frequency loss across all twelve cores in MT workloads
The above figures were recorded during Blender 2.80b runs, but they should translate almost directly to Cinebench R20 NT as well (based on my experience).
The peak power difference between the faulty and the fixed bioses is around 35W (Prime95).
Despite there is no question that a mistake was made, I'd still like to thank ASUS for two specific reasons: they didn't try to deny the existence of the issue (which btw. is the usual reponse within the industry), but also fixed it immediately.
I also do feel bad for the bios engineer, who had to stay over(over)-time to get the bios build done. Thanks for that. I also have to feel bad for ASUS, because this mistake might have smirched the reputation of their brand new Crosshair VIII -series motherboards.
And make no mistake, these are one of the best, if not the best X570 boards available at the market (a personal opinion).
At this point you should ask yourself if ASUS paid me off?
Everyone can be bought, its just the matter of the offered sum or bargain. Everyone claiming otherwise either lives in self-deception or frankly, is a moron.
I myself could definitely be bought. And rather cheaply too, I think. The thing is, just that at least until writing this, nobody has even tried to do so.
Besides of this statement, I also corrected an error AMD pointed out to me.
Despite the 3900X CPU has fused (factory programmed) Fmax ceiling of 4.65GHz, AMD only advertises 4.60GHz maximum boost.
I must admit that I was initially surprised to see the 3900X having 4.65GHz fused maximum boost limit, since AMD indeed only mentions 4.60GHz in their marketing materials.
Nevertheless, I'm yet to reach the advertised 4.6GHz either, so in that regard the only thing which changes is the CPU falling 25MHz short instead of 75MHz short of its advertised frequency.
