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

I think that's a very odd reply @Gibbo. Shurely both you and 8pack would have been well up on this certainly weeks ago ? So why are you asking forum members for advice ?

So it is odd to ask customers what they would like to see on the website.
I mean if one asking what a customer is interested in buying comes across as odd then we might as give up now in trying to give customers good service.

As always we are willing to take onboard customers request for stock and when and where we can get it we will attempt to do so.

This is not asking for advice, 8 Pack has already made a Youtube video with advice for customers regarding AMD 7000 series and like you say his testing was done weeks ago and we have the memory kits that we intend on selling and using in systems.

But what we wish to use may not cover all basis and if we see demand for a particular kit we will always consider stocking it. :)
 
Effective is what's running under load. If you run something like CB which is a sustained CPU load and your read clocks are showing 5.2 but your effective under load is showing 4.9, your score is going to reflect that of 4.9, not 5.2

All people have to do is open up the section and pay attention:

Yeah, I don't get why reviews don't focus on the effective clocks under load more. To me, it matters more than scores.

Can the ring/LLC clock be increased on Zen 4? On Intel CPUs at least, this can make a significant difference to performance.
 
Gaming? Easily. The stress is way lower than pure MT workloads. Even a budget solution like Arctic's 34 esports duo will tame it.
Depends on the game. I'm sure Ashes of the Singularity would push the CPU. Ubisoft games tend to utilize lots of threads/cores too.
 
"AMD is very clear in their cooler guidance for 7950X and 7900X, mentioning "240-280 mm liquid," but the 7700X and 7600X are supposed to be paired with "mid-frame tower coolers"

Why am I only just learning this now :D

From here:
https://www.techpowerup.com/review/amd-ryzen-7-7700x/28.html

The impression I get, is that a decent air cooler is fine for the 7700X or 7600X.

It does look as though you can run a 7900X or 7950X with an air cooler, if the all core clock speed is limited to around 5.1ghz. Maybe get better results with PBO2?

There will be no difference unless you want to use a PCIE 5 SSD (they aren't even out yet) and even then it will be many years before such a fast SSD is fully utilised.
will a 4000 series gpu only use pcie 4.0 on a non E board? whereas the E variants 4000 gpu uses pcie 5.0?

It says 'PCI Express Gen 4' in the specs here:

Maybe they will add more bandwidth for the inevitable TI version, later?
well if nvidia say it then it must be. thx for clearing that up, means i don't have to buy an E mobo specifically....but then again i might anyway in case 5000 series gpu's are 5 (for when i upgrade).

"It appears that all cards will run on PCIe Gen 5.0" (Last Updated on September 22, 2022)

?

Not saying you're wrong, but saying i've read they are 5.0, so i dunno?

Spec from official site it's gen 4

Doubt they will saturate gen 4 so not needed , but yeah nice to have on motherboard no doubt the 50 series will use gen 5

afaik hwinfo doesn't have a way to detect clockstretching. The effective clock metric is basically core frequency multiplied by core usage
the main indicator that you are getting clock stretching is lower performance
@Robert896r1
Also not all voltages are reading correct yet on HWINFO64 but I am sure you know.Check out Vcore at 2.4v.Effective clock is 5541.9Mhz,might be performance loss J/K :D

Testing cheapest DDR5 5600 Ram with default settings if anyone would like to know,I am sure Overclockers UK store have this brand in stock.
CORSAIR Vengeance 32GB DDR5 5600 (CMK32GX5M2B5600C36)


Default voltages I can run CL36 6200 and Infinity Fabric 2200.I only PC game at 4k so memory does not make any real difference.As these setting are not super aggressive or anything but they are good enough for my use case and saved me a few buck over buying the same DDR5 6200 Ram.


Do you have yours undervolted mate or just normal?
The 5700Mhz all core is overvolted first to 1.4v and PC gaming was fine.Then I lowered voltage to 1.35 and played some games.Then I went back to stress testing 5550Mhz all core with curve optimizer set to -30.I am working my way up to 5750Mhz stability testing on the 7700X and in reality that takes awhile.
Max 125 watts is nuts for that performance.
Crazy good,I have seen my 12900K doing over 300+watts.
Nice result.

Is this doable on a decent air cooler?
I would say 100% yes an air cooler would work fine,especially after adjusting curve optimizer.
