Ye, the 7900x is pointless now. The 7950X can be had for £100 extra and you'll get better quality silicone regardless of the extra 4 cores.

*** AMD "Zen 4" thread (inc AM5/APU discussion) ***
It's not a bad idea.
I think I will try the JEDEC profile first (tested for 90 mins in Aida64), but with 6000 MT/s set, at high voltage.
I suspect the motherboard is very sensitive to memory timing changes.

Going too high on voltage will cause instability too.
The temps seem fine on the modules.
At what voltage would instability normally occur with DDR5 modules?

I was thinking the same looking at prices recently - once you've spent £300 on a mobo, £200 on some RAM and are looking at a £480 CPU (so about £1000 total), why wouldn't you spend 10% more to get 33% more cores!
For people that want multicore performance surely you'd get the 7950X every time.

This is the guy you want to have a look at. Name dropped with all the top YouTubers around the world.
I was fully intending to get a 7900X and at the last second clicked the 7950X without thinking and completed the order. I still don’t know why I did it, it just happened and then it was done. I am trying to convince myself it was a good move but the 7900X would have been the more sensible option.
Wish there was a few more zen4 peeps about. Mine doesn't hit 95c with a peerless assassin (maybe 91c) and my VID is high 1.2s.
It boosts to 5.55ghz single and 5.275ghz all cores. Running in 60w eco hardly touches performance (5% in 3d mark CPU and almost nothing in single core cinebench) and drops Temps to the 50s. All core still boosts above 5ghz
I think this is fairly standard but wish there was more shared experiences

I set ECO Mode 105W and a -10 AllCore Curve and Idle temp is 33C and 61C CineBench Multi using a ARCTIC Liquid Freezer II 360. Get ~5.7Ghz single core boost and ~4.9Ghz all core. 36.5K @105W Cinebench vs 38.6K @170W.

Really impressive clocks out of Zen 4 compared to Zen 3. 5.3ghz all core?
Nearly, will have a play and see how well I can do eventually. I have no need to overclock but will definitely try it. When I got my 4790k no CPU could run FSX really well so I spent ages trying to get my terrible silicon past 4.5ghz without going higher than 90c in Aida at 1.236v. I couldn't.

So just something to post here so others looking for info similar to it may find it.
7950X with an Asus Proart X670E motherboard, the first BIOS (original, dated back in August) is total pants. And could not read 128GB (4x32GB DDR5) RAM and boot well (it barely did the 5 minute first time boot training, and would restart on itself and the second time would just stall entirely on memory training). You *MUST* install the Novemeber 2022 BIOS (or later) onto it first before installing 128GB onto the system through 4 modules (Don't know about 2 modules, as don't have 2 modules forming 128GB to test).
Memory used was 2 x Corsair Vengeance DDR5 5600 C36 RGB 32GB with Intel XMP3.0 (NOT AMD's EXPO) x 2 (NOT approved on the QVL, but a lower capacity module is listed, 2 x 16GB and that was a Samsung chip, whilst mine is a Hynix one)
The memory will be safe to run at 3600 with lower timings, but I haven't tried to push it yet. But supposedly with updates to BIOS, I may get an opportunity to try and push the available speeds from the memory. (Also a reason why I went with these to test later on, as they have the capacity to go higher if other parts would be able to)
But! If there are no further advances possible, and you are not expecting to really overclock your system with so much memory, as the "AMD Approved" speeds for 128GB for Zen 4 is 3600, you can actually get away with just grabbing slower RAM. Assuming they're cheaper and work (check QVL, but as in my case here, a non approved set worked also). But make sure to grab any matching kits at the same time to reduce chances of issues. (Mine had 2 serial numbers difference between them, so the matching kit between the two I got went to someone else, but all was most likely from the same batch).
Oh, in case anyone is looking for into on the Proarts LAN connections too; the Intel 2.5GB is the I225-V but it's revision 3 (thankfully), and the Marvell AQtion doesn't have any further name identifier, just that the version on the motherboard I have (made in August) is also revision 3 according to Device Manager in Windows 11.
To keep in relation to topic of the last few pages, the Proarts Novemeber 2022 BIOS is unfortunately busted on the ECO mode settings when changed in the BIOS. So your only real options are the moment are to use AMD Ryzen Master to go 65W Eco, or remain full throttle 170W until the BIOS is fixed. Which means a BIOS after November 2022.
Oh, and anyone testing may want to use the AMD Ryzen Master software to check on cores, speeds and voltages, as supposedly the current checkers like HWInfo64 apparently cause fluctuations on the CPU useage that give inaccurate results.
As for cooling, got my 7950X under a Noctua U12A and has reached 97C max before.
Hope this is able to help anyone looking for it.

Further info being added as I remembered them:
This motherboard has Thunderbolt 4 ports on the back. So not just USB4 connections that some other motherboards may be offering. It utilises the Intel JHL8540 for this, and this is the full thing, possibly barring some driver issues, should work with Thunderbolt devices without issue.
Additionally, this motherboards PCIe slots are, x16 (gen 5 x16 wired), x16 (gen 5 x8 wired) and x16 (gen 4 x4 wired). The Gen 4 slot is shared with the m.2 slot 3 (gen 4), and will run at x2 speeds instead of x4 when both the m.2 and the PCIe slot is both in use. However, given the network card should be unnecessary as you have 10gb and 2.5gb already on the back IO. As well as not needing USB4/Thunderbolt 4 as it's already there. This leaves you only possibly wanting a PCIe Sound Card in the system, which will set the m.2 to x2 speeds (which is unlikely to be noticed much) and the PCIe slot to x2, which sound cards only need a x1 slot in most cases. So it will be fine.
The Noctua U12A above was used to cool a default stock settings 7950X, so full power ratings were being sent to the CPU. Sending them to 5.05Ghz all cores whilst doing Cinebench. With no other offsets or anything in use. With ECO 65W mode active, the 7950X runs at 4.0 to 4.1Ghz all cores with the CPU barely breaching 48C. Although temps and voltages are current in question due to software checkers currently not granting entirely accurate results as listed above.

does it have the temperature limit setting?
Set to 70, will behave same as ECO mode in essence.

7950X @ £549.99 today!

Yeah it's getting really tempting.

Hi Guys, think i might have bought the only faulty 7700X
ASUS MB wants to set the FCLK to 2000 by default (optimised or EXPO) and the CPU says no thanks to that and i have to mess about and manually set it to max 1900, has anyone else had that issue, i have put a web request in to see if i can send this as faulty.

Oh, nice idea!
There is indeed a temperature limit in the BIOS settings, however (having just tested it), utilisation of that remains as though it was never activated. So either I and others have missed out on some settings that would permit ECO mode to work properly, or the BIOS of this motherboard (November 2022 version) has borked the ECO mode control. Whilst I didn't get to try with the previous BIOS due to having 128GB installed, the other user elsewhere did use the previous version to utilise ECO mode. But they found that in the newest BIOS (November 2022) after they updated, the Asus Proart X670E motherboard refuses to keep in line with settings set in the BIOS. So given both findings, I provided the details in my previous post.Hoping the new BIOS gets released soon with BIOS controls, or AMD release a newer version of Ryzen Master that offers 105W ECO mode. Would make life so much easier then too.
I think I may have found a solution to my system's DDR5 instability, at least in the Aida64 benchmark.
I tried setting my timings manually via the AMD overclocking menu (under the Advanced heading), rather than via the 'OC Tweaker' (leaving the timings here set to 'auto') menu, on my ASRock B650 motherboard
I set some fairly loose timings (40-40-40-80) to see if I could get stability with the DDR5 frequency at 6000 MT/s. I set the other timings to 'auto'.
These settings are stable after 3 hours, with 1.45v set for the DRAM voltages and 1.4V for the VDDG voltages. I haven't tried lowering these voltages yet.
I'm now testing these timings with the same method:
28-38-38-80
EDIT - These settings appear to be stable after 3 hours of testing...
I don't know why setting the timings manually via the overclocking menu (under the advanced heading) seems to result in stable timings...
Anyone know why that may be?
Also, do any of the other timings have much impact on performance, or can I just leave these on 'auto'?
