Vast majority of AM3 mobos just needed a BIOS update to use AM3+.

It was largely the bottom bin chipsets that didn't get an AM3+ upgrade.

Supposedly it affects only certain Ryzen processors and more recent ones are unaffected. Don't think there's a big database of affected/microcode/production date to confirm though.

I can now confirm that a Ryzen 1700 is just a wee bit faster than an Athlon II X4....

I managed to get it running with the memory at 2800MHZ with just two mouse clicks and no understandings of what I was doing. The rated 3000 failed to boot so I'm going to have to RTFM.
it might be 2T at 2933, since ryzen by default demands 1T memory timings unless you update the bios to one with a newer AGESA version (not all of the mobos out now have it although new ones are shipping with it)

though 1T 2800 might be faster than 2T 2933 and if it's stable there after some stress runs i'd say go with it

At the time (early 2000s) Itanium looked like the platform that will free us from the clutches of x86, with all its hacks and band-aids upon hacks and band-aids that it received over its long history. Alas, it wasnt meant to be.
It probably would have required even more hacks considering it was largely an excuse to lock in vendors.

Turns out people should have switched over to ARM a long time ago, but hindsight.

whats the least problematic ryzen ram? What guides are there to get it to work?

I'm getting sick of it not posting 5 times, then having to go into the bios, change nothing, restart, just to get it to run 2933 on 3200 QVL approved ram. THis is every single time I turn my PC on.
You might have to set the clocks/voltage manually and loosen timings, it might just be trying to do the XMP profile each bootup despite it obviously not going to work with Ryzen in most cases. I've had a similar problem with an Asus B350 Prime, but with non B-die ram.

There isn't a comprehensive list of ram that works with Ryzen because there's just thousands of SKUs, but there's some known Samsung B-die ram sticks. Unsurprisingly their prices are inflated.

I have a question regarding Threadripper. Looking at Puget System's benchmarks of Adobe and CAD suites, Intel's similarly priced 7900X typically matches or keeps up with the 1950X in multithreaded tasks but completely slaughters it when tasks are poorly threaded. Unfortunately, there isn't much to compare with as most reviewers don;t go much further then use Cinebench, don't test professional programs or don't really go into detail what they're actually testing.

Assuming Puget Systems' benchmarks are accurate, is there an actual use case for Threadripper if I don't need the ECC memory support or 64 PCIe lanes,
you could just buy a 7700k

The i7-7960X @ 4.1Ghz default voltage pushes total system power to 687W, comparable 1950X @ 3.9Ghz is pulling 552W. the 7960X could go higher but it tries to bake itself first @ 4.1Ghz, so have fun delidding a 1700$ CPU to possibly eek out that extra 10% performance and 100W extra.

Isn't that setting up for another round of "Ryzen vs Kaby" comparison, except Intel will still be on 14nm IIRC? I keep hearing how Intel keeps pushing back 10nm and I'm getting visions of AMD leapfrogging them for 6 months which can be outright devastating.
AMD coming out with a 7-actually-10nm product that performs before Intel can push out their 10nm laptop chips would be quite hilarious but given how tapeouts work we won't see such chips until Q1 2019 +/- 3 months, unless they want to do another crash test dummy run and push out barely-ready-for-production chips for consumers like they had to for Zeppelin.

the second attempt at doing maxwell-era CUDA primitive discard

worth noting that nvidia backported primitive discard to kepler and fermi for a significant performance boost shortly after the first maxwell card hit, that AMD can't somehow do this for GCN is probably not a good thing for the graphics uarch i think?

Is there an microarchitectural reason why Intel beats AMD so hard in single-thread performance, or is it more due to incremental improvements over time?
before Zeppelin, AMD backed the wrong horse of SMT vs. CMT, among other pitfalls like realizing too late that bulldozer adapts incredibly well to low power applications and has a very sharp efficiency decline after those low power targets, before adopting a top-heavy version of intel's uop philosophy and making it up to 90% of the way there in IPC

So are these new Ryzen desktop CPUs with graphics included going to be made obsolete in three months for Zen+? If I’m running a PC that’s a glorified torrent box that also runs Handbrake a few hours a day, which do I want?

I’m thinking the R3 with graphics is looking nice, it if Zen+’s 3 also has graphics then might as well wait.
depends, if you're looking for a discrete card (a really bad time to do so imho) they will be made "obsolete" in 3 months, if you just need an office home kids pc with no frills there really is going to be no better option for a while as it has the happy medium of adequate single core speed and playable framerates at the "bare minimum pleasant to look at" graphics settings and the next APUs with zen+ will be 8-10 months off

zen+ is going to be a 200-300mhz clock speed bump over zen so it's basically the average intel improvement

if you need a chip now get it now, otherwise you can continue to play waiting game for a while longer

AMD actually does frequency binning, which is why you have a pretty tight range of overclock expectations per SKU with relatively few outliers and out of those, they seem to be restricted to utter comedy like an 8 core R3 1300x
