@Sahaj that is most likely the one I will go with. The 65w parts are just so easy to cool.
I'm stoked on this too, our office PCs are really getting old with i3-2100s in most. Want to rip them all out and upgrade to 3600.
PCIe cards are almost always backwards compatible. If you are using a PCIe gen3 Riser, the card will negotiate at PCIe Gen3 (most likely). If you are lucky it might work at Gen4, but if you have instability you may need to go into the BIOS and specify Gen3 speeds manually. There will have to be lots of testing and trial & error before we figure out everything.
Talked to ADT Link who makes our riser and the riser in the Dan A4 v4 - confirmed the current risers work for these new AMD boards as 3.0, but do not support PCIe 4.0.
They are working on a PCIe 4.0 and PCIe 5.0 riser as well, but nothing available anytime soon.
X570 does have bifurcation support as well! Hope to see a lot more boards supporting it.
Well, if we take AMD's 15% IPC improvement to heart, a 4.6Ghz frequency from the 3900X would only be matched by a current 2000 series Ryzen at 5.3Ghz. And I'm sure with good cooling the 3900X should be able to be pushed to 4.8Ghz or 4.9Ghz. I dont really expect the 16 core to clock higher. I'd be interested to see if the 280mm rad can keep up with an overclocked 3900X.
More importantly, do you know or has Sliger said whether the SM580 would fit some of these MiniDTX motherboards?
Motherboard companies sure seem to be embracing the overclocking features as well, which if the OC results were underwhelming I don't think they would do.
I am hopeful that reviewer OC testing comes back with even higher performance potentials than people are thinking are possible now.
Also given the TDP of the 3800X should be fine on a 280mm radiator even with a good OC. I've seen a few 9900K OC'd to 5GHz cooled by a 240mm.
The DTX base board would fit in the 570 or 580, but does not seem like the daughter card would fit based on height. This DTX board was build for an M1 or A1, looks like I'll have to make a S1 or something.
