Alastair is talking about broken Vega 64 overclocking when a *LC BIOS* is used on a non LC Vega 64 reference card, even when the non LC card has a high end water block and temps are splendid. So temps and hotspot etc are *NOT* an issue! And since reverting to a very old driver fixes this, well it's very obvious it's driver related. Malicious or not, I don't know.
Specifically, extremely bad throttling and very bizarre performance issues, which only go away if the non LC Bios is used *OR* a much older Vega driver is used (where upon things suddenly work perfectly again).
CORRECT! THIS MAN GETS IT!
I think it's malicious.
Because a pattern has emerged of AMD breaking something related to overclocking with a driver update very near to the launch of a new flagship product.
Fiji. HBM overclocking worked since launch. Broken with 17.1.1. Close to Vega launch. Amd claimed there were significant changes under the hood of the driver. That it necessitated breaking HBM clocking.
Vega. Vega 56 and 64 owners have been free to use the Liquid edition BIOS for the extra voltage it provides which meant more overclocking available to those who had the cooling capable of taming a 1.25v Vega. (this isn't even mentioning the fact that you can't over volt the standard bios. Only undervolt.) but then 19.2 drivers roll around again right around VII's launch and boom! Normal 56 and 64 owners can't use the LC bios as it just tanks the clocks HARD.
VII. 19.8.2 or 3? I dunno I don't have a VII. Right around the time Navi comes around. Boom. Overclocking broken.
This is a pattern. Happening once I can say definitely maybe a mistake or a bug broke things.
But this is a pattern. Each time an ex flagship getting gimped. Each time something related to overclocking. Each time close to a high profile product launch.
My thoughts? Hey if we can do something to get those guys that are willing to pay 500 600 even 700 dollars for a card, to move on from their old cards a bit quicker and get them to buy our new ones? PROFIT AM I RIGHT? -random driver team member suddenly finds himself promoted.
Amd isn't in the business of making friends they are in the business of making money. And I don't think it is out of the relm of possibility that now that they have had a taste of success with Ryzen and what not. Now they want more. The board wants mkre. And they are pushing to find ways to push sales up.
And if they can break things that weren't "officially" supported in the first place like HBM OC on Fiji and LC bios use on standard cards. Then technically they can get away with it. Cause it wasn't officially supported any way am I right? So let's break features that we don't officially support and condone and get those guys to duml their old hardware quicker.
