If the die is bigger won't that mean the TR4 socket will be incompatible so that a claim for backwards compatibility woud not hold water?
Personally I think if a new chipset is required that a new MB is mandatory so why not have an enlarged socket?

No the dies are smaller. The process node for the chiplets is 7nm versus the old process node size of 14nm. The I/O die is 14nm. So basically the new chiplet dies are 1/2 the size of the old Threadripper CCD complexes. The socket is still the same at 4094 pin count. The Threadripper socket is the same socket used for Epyc server cpus.

Who said a new chipset is mandatory? If the new X599 chipset only adds PCI Gen. 4, then you can basically skip it just like most people are skipping upgrading to the X570 chipset. Unless you have massive storage needs, the old x470 motherboards are fine for Zen 2. I expect the same case to hold true for the Threadripper 3000 cpus and the old X399 motherboards.

Ponder this image to get an idea of scale. The image shows the interconnects on a Ryzen 3000 cpu substrate to connect one chiplet to its I/O die. Amazing.

New CPUs coming over the horizon: https://www.tomshardware.com/news/ryzen-9-3900-ryzen-7-3700-ryzen-5-3500-amd-3000-series,40040.html

A 12 core, 24 thread 3900 with a TDP of 65W now sounds interesting enough for me to definitively wait with buying the hardware part of my new system.

The Ryzen 9 3900 features the same 12-core, 24-thread configuration as the Ryzen 3 3900X. The non-X variant has a 65W TDP (thermal design power) rating, and as a result, the chip will likely come with lower operating clocks. The same could probably be said for the Ryzen 7 3700 eight-core, 16-thread part.

Been having a discussion over in the Threadripper threads at OCN. Lots of speculation what TR3 will bring to the table. I expect both leaks and announcements in December prior to January 2020 CES event.

Interesting.

Nothing unexpected from what I have seen. This is a new process. As the process node improves, the binning will get better and there will be better parity among cores of each CCX. Just give TSMC and AMD a year to sort things out. Took that long to sort out Ryzen 1 too to get to Ryzen +.

One of the practical reasons to never adopt first generation or first iteration of a product. Let the pioneers be beta testers to find out the kinks and quirks and THEN buy a properly finished product.

This is a well known problem with the current AMD drivers that are for the Navi 5700XT cards. OpenCL is totally broken. So no 5700XT cards should be run on BOINC using the AMD OpenCL drivers.

Message 2005140 - Posted: 1 Aug 2019, 12:39:40 UTC - in response to Message 2003070.  

SoC voltage can have a large effect on attainable overclocks and stability. You might try around 1.13 - 1.15V on the SoC. If the mobo wasn't a APU host, I would say go the other way and drop SoC down to 0.95V. A lot of people have found that cranking ever more voltage into the SoC is counterproductive for achieving higher memory overclocks. But again, the APU is whole different animal. Tuning memory on Ryzen is much harder than on Intel since the platform doesn't have ten years of prior experience like Intel. The Calculator really helps get you to a starting point faster.

Also Samsung B-die memory likes voltage. Up to 1.5V is acceptable. You have those in your Flare-X kit. I would raise the Vdimm voltage to 1.4V right off the bat and see if you can't get 3333 or 3400 stable.
I finally got 3333 stable! I'm not sure if it is because I updated the Bios to the latest (went from 3.40 to 3.50, which uses AGESA 1.0.0.3), 1usmus' new calculator, or the fact that I didn't set the bclock. I'm guessing the latter. While trying to OC the ram, I noticed in HWinfo that my clock was at 99.9, which I know is probably close enough, but it wasn't 100. Bclock was set to auto, so I set it to a firm 100, which HWinfo read as 100.1. With the bios updated, I couldn't find a way to adjust the bclock, so I am assuming it is on auto.

I did try 1.4V earlier, when I was setting bclock, and that didn't help (I think it made it worse). I'm within the recommended range (1.375 Dram, if I recall, and 1.0875 for SOC). I'll play with it a little more tonight, but for now I'm happy with the little boost I've gotten!

You shouldn't worry about the reporting of the BCLK being not exactly 100.0Mhz. Ryzen does not have any internal sensors to measure BCLK unlike Intel. So any monitoring program is only guessing. Some people are anal about that and go to changing BCLK from Auto to a manual number just to get the BCLK to read 100. But that messes with Ryzen's automatic internal adjustments.
The change in AGESA versions is likely why you can achieve 3333Mhz now. The BIOS' keep improving the memory performance.

The Ryzen line is doing so well that last month 79% of CPU sales were AMD and only 21% Intel.
(I'll definitely be giving one a go next time I need a new CPU/board combo.)

I was disappointed when my old systems died earlier last year within weeks of each other as I was waiting for these new Ryzen cpus to come out.
I'll just have to wait and see how things stand in another 5-8 years.

Or until the 3950x both starts shipping and it stays available long enough to order one at its MSRP?

I'm not sure I would recommend the 3950X right now with all my issues with my 3900X. I probably will pull the 3900X and put the 2700X back in.

A brief note. In another thread Keith has just reported....
The over temperature shutdown errors that Keith has been fighting turn out to be an error in the Ryzen 3000 Bios code which is shutting down all of the fans running off the motherboard. So the cpu overheats.

This is apparently specific to the ASUS mb he is using or to the specific model of ASUS that he is using.

Keith's workaround is to drive the fans directly from the PSU.
