Been using this bios for a bit now on the Hero (was available in beta from the rog forums). It's definitely better for stability. I still have issues with curve optimiser but that could very well be me not understanding it correctly.

*** AMD "Zen 4" thread (inc AM5/APU discussion) ***

Me either. I've not had one issue on AM5 since switching from AM4, and I've been using a 4090 on it too. The platform is incredibly polished compared to AM4 at launch.
AM5 ain't going anywhere for a long time yet rumple. Feel free to bookmark this quote and thank me later.
Spot on bud.
Yes, 0805 is great and I highly recommend using it. It unlocks Geardown mode tuning (ADD_CMD mode under DRAM tuning) and adjustable tREFI for memory.
Leave it enabled for better gaming perf.Has anyone tried disabling CPPC on a Zen 3 or Zen 4 CPU?
I've disabled it and not noticed a difference (yet), but then my performance is good anyway...
There's an interesting thread about it here, testing on a 16 core Zen 3 CPU:

EDIT - I tried AC:Odyssey and the minimum frame rates were significantly worse with CPPC disabled (sometimes dipping down into the 20s during the benchmark test).
I think because the game has terrible thread management.

Can someone explain why enabling CPPC is considered to be a good idea for Zen 3/Zen 4 CPUs?
For my Zen 4 CPU, the 8 CPU cores typically run at 5.2-5.3ghz, with a PBO curve of -30. Around 5.4ghz when only 8 threads are being utilized.
So, if the frequencies are high on all cores, does CPPC offer any performance boost at all, by prioritising the use of some cores over others?

The guy must be a bit of a noob. Not had anything like that on mine and he's the first post I've read about it
After looking into it I can see a fair few regarding the bios not booting at least. Mine has been ok since updating.
Corefail
I'd really like to believe him but it's just so hard when RDNA3 ended up half the performance as he promised it would be

Updated today. Not really anything to report yet. The slow boot memory training thingy is still there.

Interesting, was about to pull the trigger on a 7900X to start up the new rig. Guess I'll hold for another few days more over the new rig then.
AMD Ryzen 7000 gets a massive price cut in Europe, 7950X now for just 669 EUR - VideoCardz.com
AMD Ryzen 9 7950X drops from 849 EUR to just 648 EUR It looks like AMD Ryzen 7000 series are getting much cheaper for European customers. Update: Ryzen 7000 series are now even cheaper, this post has been updated accordingly. Some retailers in Europe are beginning to discount Ryzen 7000 series...

Further info here. Zen4 can't be selling well for these price cuts to happen, though you can be sure that AMD investors on this forum will come up with an excuse for why this isn't so.
Imagine paying full price for a 7950X on launch day, only for it to be £200+ cheaper just a few weeks later!
Personally, I'm hoping this means Zen4 with 3D cache is coming Jan/Feb, though the lack of leaks is frustrating!

Although it's nice AMD is cutting the price of the 7000 series the price of the CPU's isn't the problem. It's the prohibitive cost of the AM5 motherboards that needs addressing.
The price of motherboards in general is gross these days. I just had a look through my emails and I paid £175 for a Maximus VIII Hero Alpha (plus £276 for a 6700K to go with it) in May 2016, which was just a few months after it launched. That was a higher-end board at the time and a beefed-up version of the regular Maximus VIII Hero.
£370 now for a 7700X, quite a good price. I think it has been priced to compete against the 13700 (non K), releasing in January.
Cheaper than a 13700K, which is now priced around £450, or the KF for ~£430.
~£200 for a B650 motherboard that is quite capable and future proof (especially compared to my last motherboard) doesn't seem like a bad deal to me.
The somewhat costly bit is still the DDR5 RAM. It's possible to buy a cheaper kit though, so it depends how fussy you are
It's a bit pathetic how some people are already trying to play down the lifespan of AM5, saying it will only last 2-3 years lol. Obviously Zen 5 will be supported, and probably a couple more after that.

Z690, DDR4, 12th/13th gen i5/i7 is by far the best price/performance, and the sensible purchasing decision for the vast majority of people.
It isn't cheaper for a new build, except for the DDR4.
If building a DDR5 system, the 7600X and 7700X are well priced. Realistically, if building a new system, most are going to want to get the best performance out of it.

Err, no. The price of a AM5 board, DDR5, and CPU is significantly more than a Z690 board, DDR4 and 12th/13th gen CPU.
There's no reality, apart from the deranged reality of the most loyal AMD fan, where the above isn't true.
Are you factoring in the cost of a new motherboard and a kit of DDR5 if they want to bring their system up to date in a couple of years, given that LGA 1700 is now a dead socket? How are those people who bought a Z270 setup back in 2017 getting on these days?
Don't think it is anymore looking at the price cuts on 7000 series, you can get b650e boards in £200 range that's with gen 5 PCIe and 1 m.2 gen5 and the boards not being locked, the platform has longer life , zen4 3d, zen5 , zen5 3d still ahead
Personally I wouldn't wanna do a new build with ddr4 now seeing the difference ddr5 is starting to show
Didn't you go with rocket lake build over AM4 build ? Now that's loyal
