These two TR 3000 models are a little more than two 12C or 16C Ryzens put into a single socket: Somewhat more than twice the sustained power consumption, with exactly twice the core count, certainly also nets you a little more than twice the computation. At the same time, MSRP of the processors is more than twice that of the Ryzens. And according to rumors, TRX40 mainboards will cost considerably more than twice than AM4 mainboards. Lastly, there are many more cooling options for 105 W class CPUs on a mainstream socket than for 280 W ones on a server-derived socket.It looks like they'll be great for content creation but TDP is high so are they the best choice for DC?
So I guess BIOSes of consumer mainboards refuse to boot without PCIe GPU or IGP. There is however an AM4 server board from ASRock Rack which comes with a baseboard management controller (BMC), X470D4U. Naturally, it is more expensive than a standard AM4 board + small PCIe GPU. And judging from the manual, the BIOS lacks options such as cTDP. If so, this board can't be used to tune Ryzen to efficiency levels of high-end Epyc models.Until then, does anybody know [...] whether it is possible to operate Ryzen 3000 (non -G) PCs as headless Linux nodes, i.e. without a graphics card installed?
That is precisely the reasoning that I used, in picking up / assembling multiple AM4 Ryzen R5 1600 rigs early-on, rather than TR4 rigs.These two TR 3000 models are a little more than two 12C or 16C Ryzens put into a single socket: Somewhat more than twice the sustained power consumption, with exactly twice the core count, certainly also nets you a little more than twice the computation.

Somehow I can't recall any CPU project with highly uniform work units. But there is always the option to re-run select tasks outside of boinc. (Except for certain wrapper projects, such as some of the LHC@home subprojects, which side-load the real task definitions within the boinc task.) So we can eliminate WU variability in almost any project, but none comes to my mind for now in which we wouldn't have to go through hoops to do so.Once the WCG challenge is over, I'll have to do some experiments. Any suggestions on a boinc project?
I agree!!
I'mumm er my friend trying to decide between a x470 OR x570. I quite honestly do not see me needing a 570 but I am concerned about cooling of the VRM on a 470 running a 3900x. I find nothing that says there would be any issue with my YouTube worm hole I have fallen in. I do have an x470 MOBO that I could swap out the CPU and see if I run in to any issues. OTOH I'd rather start from scratch with a new machine that is to replace my DD. Either way I have time to decide since there is nothing wrong with my current DD.
Interesting, I've been thinking of needing something like that for benchmarking MW for a few years, and somewhere around 10yrs ago for SETI! How do you do that?But there is always the option to re-run select tasks outside of boinc.
The MSI B450 Gaming Pro Carbon AC has a very well regarded VRM cooling & power delivery circuit (and a decent sound chip too, unlike the Tomahawk!), and it's Bios supports Zen2. I am primarily looking at running a 3600 on one of these, but IIRC it should comfortably run an 3900X too , but check that!
Btw, what's DD?
Ah, I knew that for cars, didn't know it was used for PCs .
On refreshing my memory it seems that this mbrd might not be suitable for 3900Xs after all, although I'm getting conflicting info between THG's & Techspot's article of this mbrd.
THG says it has 8*+2 Phases (*Doubled) VRM (which is what I recalled), whilst Techspot says 4+2 , so I'm not sure now & I'm still reading into it atm (again!).......
Maybe this VRM Tier list will help?
It seems I was getting CPUs mixed up, so the MSI B450 Gaming Pro carbon AC should be fine for the 3700X & 3800X (8C) but likely not for the 3900X according to that list, that said MSI show CPU support upto the 3950X! So I'm still not sure!
Lane 42's post on the 1st page states you need at least 8+2 for 8c CPUs.....
Automotive world here too , I'm a car mechanic (inde & Suzuki with my current job).
Daily Rig might be best for PCs .
B450s are cheaper still than the X470s, seems the MSI one will be plenty good enough for me, the X570s are silly money as far as I'm concerned.
Pretty much all of the mainboard makers claim compatibility with all of the Ryzen models up to 105 W TDP for pretty much all of their mainboard models. Some of these claims may not make all that much sense.
EDIT: Cheaper except that I don't get the game bundles (nor the tax)...
Curious as to where you find the 3800X cheaper than the 3700X at?Nope, I keep finding them for less than the 3700X...I guess the TDP has made them unpopular...
