Kinda agree with most of that.
a lot of hang ups over the wrong things to be concerned about.

I'm not sure if this has been asked or discussed previously but I am curious as to AMD's options in regard to assembling the Ryzen 3000 series.
We know that each CPU can contain up to 2 core chiplets together with an IO die.
With 6, 8, 12 and shortly 16 core chips available, what are the possibilities that AMD can make these CPUs in more than one configuration, but call them the same thing?
For example:
The 3600x is 6 cores and contains 1 ccx with 6 functioning cores.
The 3700x is 8 cores and contains 1 ccx with 8 functioning cores.
The 3900x is 12 cores containing 2 ccx with 6 functioning cores in each.
My question is, can AMD make these CPUs using other combinations or does it have to be done this way?
ie - Could the 3700x be made using 2 ccx with 4 functioning cores in each, etc.

Technically they can, but splitting 'clusters' of cores over chiplets causes latency issues, so they likely wont.
Where they can have all the cores on one chiplet, it will be one.
Where they need more cores than one chiplet, they'll do an even split upto the chiplet max core count.
I don't see why not, but yields would have to be exceptionally low to make doing so worth while. You'd hope that the vast majority of chiplets had 8 working cores and just get binned to the different chip types.

There must be some 4 core chiplets that are currently unused. Could make an 8+4 chip or a 4+4 chip (more cache than a single chiplet chip).
what if i give 0 ***** about idle temps power consumption and cpu needs to last 14 maybe 20 months max ??? Have You miss part that im benching on my DAILY settings over 200w ??
and my temps are still lower than people using stock 3900 cooler most aios and air coolers at stock settings

Not 100% on this but I think the amount of cache per core is always the same on zen 2 and each core can only access it's own cache. Different to intel which has a unified cache pool which any cpu can access.

You have a 3900x? Can you help me with how to set it up? I will recieve one in the next day or 2what if i give 0 ***** about idle temps power consumption and cpu needs to last 14 maybe 20 months max ??? Have You miss part that im benching on my DAILY settings over 200w ??
Flash new bioses with 1.0.0.3ADD taht came out today on Gigabyte for start hehe. Should be plug and play I'w not had any problems with running it on Crosshair VII. No boot problems ect and found workaround for small bios bugs.
Like there is problem with 3800/1900 memory training you get stuck on C5 or 07 post error. Can be fixed by running Bclk 101.8 as I do its bit faster than 100bclk but solves memory training problem. So If You got spare time Read up on what bios bugs does Gigabyte have on x470 motherboards and Zen2

Then just switch back to old profile?
AMD should be sensible and create profiles for mass users, not extreme overclockers.
Also you could customise that profile, and if you use the script I posted last week, you can fully unlock the settings in control panel and customise every aspect of the profile.
v3 of DDR calculator came out
https://www.computerbase.de/downloads/systemtools/dram-calculator-ryzen/
1usmus added support of Manual more that I suggested
https://www.computerbase.de/downloads/systemtools/dram-calculator-ryzen/
1usmus added support of Manual more that I suggested
- Improved compatibility with older operating systems (conditions .Net Framework 4.6.1 and Runtime libraries is present).
- Improved support for low resolution monitors.
- Improved timing calculation when using the Manual profile (as it used to be called Debug). Due to numerous requests, the algorithm is partially used from version 1.0.0 beta 3 + significant improvements.
- Changed the frequency limit for Samsung b-die and Hynix CJR. Samsung b-die has no restrictions for the Manual profile.
- MEMbench сalibrations for 3900X and 3950X.
- Bugs fix
its not the Power profile !!!! I dont even use ryzen power profile have not been using power plans from windows or AMD since Zen1 came out. Them 20 quid or whatever Totally worth it
https://bitsum.com/
hem 20 quid or whatever Totally worth it.
is what a power user needs and wants. For example I can assing to use specific CCX ot chiplet to a specific application. I can test if game runs better or worse with SMT on and off and have it set up /game.
Normal power plans are plain junk compared to customisation options this provides me.
I got set up on the fly power plan switching. Depends if im gaming benching or reading internet. Thats why I drop to 25 wats when reading internets and can pump 205 with no limits at any point when benching or stress testing.
Chipset drivers reduce performance by themselves while reducing my system stability ALSO. In my case there is No gain just looses all around from them trivers.

I have time, but I'm late to the party and have no knowledge of these new chips and what to do with one. I have a 2700x currently, can you direct me to readable or watchable something?
Have you tried
https://www.howtogeek.com/368781/how-to-enable-ultimate-performance-power-plan-in-windows-10/
It's bery similar to bitsum maximum performance power plan that comes with process lasso
Cant think of anything. You are lets say 'late' to the party so You will have 3rd or 4th bios that should have most problems fixed by now
I deffo preffer all core overclock over the Auto on 3900x

Gskill selling 3800 zen2 kit. They could have shown 1000% HCI pass as an well known memory vendor i seen fails at 200%+

I should be able to drop main clock to cl14 and fixt timings up a bit not gone to CL14 theritory yet to test. As on OCN we noticed performance gains from cl16 to cl14 are very low on them 3733/3800 clocks. But ill drop em after i get home to show ya what sorts of gains there are.
@8 Pack any update on Your's Zen2 dedicated kits ??

There is 2 limitations in play.
1. Same number of cores must be disabled on every CCX (so can't do 12 cores with 8+4 configuration)
2. L3 Cache of a CCX can't be halved. So a potential 4+4 CCD to get 8 core pseudo-3700X will have twice L3 cache compared to 3700X and will have to be a different SKU
See for example Ryzen 5 1400 vs Ryzen 5 1500X. Same number of cores, twice the cache.
(Or possibly will have a whole CCX disabled on each CCD)
Ok testing new ryzen calculator with sugestions iw made. WORKk MINT on manual mode. Now You can calculate max for Your's specific ddr kit about to start HCI memtest on this for 201% or so.
Benchmark vs my tweeked settings from yesterday.
https://bpcprdstorageacc.blob.core....387115a9152caf5244f608f5858d1164adb079e9.jpeg
Max power draw when testing went up by 2w but thats cause i boosted ddr voltage to 1.45 just to see if its working so back to my tvolts and lets see.
