Ditto. Watch your temps. You won't want to run volts that high in some benchmarks. I still haven't pushed that much voltage in Prime95 SmallFFTs or that awful PrimeGrid workload Larry had us all run. Also, I recommend that you use CPU-z to monitor voltage since some other applications can under-report voltage (and/or provide conflicting information).

In any case, learning how to manipulate default clocks can have some benefits. If I know exactly what I am (and am not) going to run, I can dial in a static OC and be fine, but if I want to be able to run anything casually without planning in advance, then default mode is the best option.
 
@Kocicak

I noticed you have a (now locked) thread on a 3800x's boost behavior. All I can really say is: imagine taking the "good" CCD from a 3950x and restricting the max boost to 4.5 GHz instead of 4.7 GHz. Viola! Now you have a 3800x. They're a very high bin, and they're likely capable of boosting on individual cores above 4.5 GHz were their boost maps capable of such.

As for all-core OC, the only way you will know is to try. Don't assume that all-core OC = higher temps (except in stuff like Prime95 SmallFFTs and similar, where you will want to be cautious). Try CBR20 or Blender Benchmark, and use Ryzen Master to set your voltage to something conservative like 1.2v which should be "safe" even with Wraith Prism. See how far up it will clock before it crashes, and monitor temps. You can squeeze out some extra stability by increasing VRM switching frequency in the UEFI. Not sure what you will want to do with LLC settings; on older AGESA versions, you had to get aggressive with LLC on some boards to increase stability at a given actual voltage, but in 1.0.0.3ABBA, lower LLC seems to be slightly better (not sure why). Use CPU-z to monitor your voltage since HWiNFO64 can give some wonky numbers (not sure about HWMonitor, but I'm not a big fan of it for Matisse systems). If you set 1.2v in Ryzen Master, you may get much lower "actual" voltage thanks to vdroop, which means you'll have to set it higher to get the desired number. So test with some low-ish clocks (4 GHz) just to check your vdroop and tune that voltage until you get exactly 1.2v (or really close to it) under load. Idle voltage is largely meaningless.

Thanks, I’ve got a lot of reading to do. 1.35v is just the upper bound for me for safety and long term reliability. Some people are pushing much higher volts, and I think they are crazy. Do you have a link on manipulating default clocks, are there UEFI adjustable profiles?

I can only advise from personal experience. Your mileage may vary based on the board. All you do is lower LLC as low as you can get it, and then try putting in a negative voltage offset. I use -.1v . It should boost your MT performance and lower ST by a tiny bit, but only in strictly ST applications. Anything using 4 or more cores and you gain performance overall.
 
Is a 3800x just as good at gaming as a 3950x? I understand that the base clock of the 3950x is only 3.5 GHz but what do they tend to run at when 8 cores but no more are fully loaded?

Seems like it, though the 3800x is limited to 4.5 GHz boost frequency even though it seems like it could boost higher. Some 3800x chips can get multiple cores to run at that speed at once, at least for a time. Try to ignore the base clock since it's more of a suggestion than a reality.

I didn't really follow the Ryzen 2000 - > 3000 bios updates for existing boards scenario. But hypothetically judging by how each manufacturer handled them how would you rate them in terms of hypothetical Ryzen 4000 (Zen 3) support?

There has not been an official statement yet whether or not Ryzen 4000 will be AM4 compatible.

(Ryzen 4000G, i.e. Zen 2 based APUs, most likely will be, although not even this has been confirmed officially AFAIK.)

The wording was "through 2020." There's a slide somewhere for it. I'll have to dig through some articles. Through 2020 or just about any year means that year included. I can't see why they'd drop AM4 support with a new generation. That's what AMD said in 2017. Last year there were some lame reports that it could end in 2020. Zen3 is doing some new stuff, but I can't imagine it being so different it would get the TR3 treatment. I've heard some rumbling rumors on Zen4/Ryzen 5000 which may require a new layout.

Correct. This is why I said that 4000G will most likely be AM4 compatible. Anything else is mere speculation, and I leave it to those who enjoy that sort of pastime.

Yeah, I forgot to edit that out. Honestly, I'm coming from Z77X and it doesn't bother me. I know people I built for on X470 who'd prefer not to upgrade to a new motherboard. But even if it's 3 years on AM4, that's still good. Think AM3 and AM3+ had relatively long life spans, with AM3+ lasting 5/6 years?

I can't say I'd be pissed if I invest in X670 next year and sit on that build for 4-5 years. Or do you think they'd pull another AM3 with backwards compatibility for the Ryzen 5000 processor on AM4, but get rid of it with Ryzen 6000?

I realize there is nothing concrete but it'll have to be a risk to take or I guess return the whole lot and hold out to next year for either Intel/AMD, which I'm thinking about doing (Amazon holiday return window).

If your Main use is gaming, you will find almost no difference between the two. Your GFX card is where you want to spend the most $$s.
 
I right now have a GTX 1080 Ti for a graphics card and a i7-4930k for a CPU. Is there a graphics card worth upgrading to that will make a big difference in performance besides the RTX 2080 Ti?

What monitor do you game on (resolution and refresh rate). Are you playing current AAA titles?

3600 with a Hyper 212 tower cooler, running Rosetta@Home all night at 100% usage, peak CPU "Tctl/Tdie" temp 79C, peak CPU CCD1 "Tdie" temp 81C, all-core sustained 4 GHz, max boost 4.191 GHz - with peak CPU Core Voltage 1.437 and average 1.352. "Auxiliary" temp on motherboard (ASRock B450M Pro4 -- I'm guessing VRM) peak 88C.

Any of that look out of the ordinary?

sounds normal to me.

I'm not fussed about the timeline. I wouldn't be a Zen 3 early adopter regardless. If I wasn't concerned about needing Zen 3 to keep pace due to the next generation consoles I wouldn't even upgrade.

Really the problem would be no upgrades. I think (maybe resolved now) MSI for instance had a lot of issues due to the rom size issue you mentioned. Although oddly with their revised Max boards all having the larger 32MB roms they might be ahead of the curve next time around at least for those boards.

The Asrock B450M Pro I mentioned I had a concern with as it seems like they still haven't a bios with the newest AGESA, so I wonder what the longer term support for that would be (given the also low place in their lineup).

One of the reasons I had originally planned to go with the Asus B450i Strix was the large rom size and that I guess Asus has the scale to amortize costs in providing updates.

The last option thought about was to just hold onto the CPU (and maybe memory) until B550 boards come out.

I cannot remember where i read it but the Asus B450 boards are below average and MSI B450 are the above average. i personally would wait for B550.
 
I can't get my memory to run at 3200MHz on my MSI B350M Mortar motherboard with my 3700X. This comes as no surprise, since my previous 1700X had the same problem. But it works well enough at 2666MHz. I may upgrade to a B550 motherboard if any of them have the required features but I'm in no hurry.

Try a different bios and see if that helps.

That's a good idea. I tried flashing the latest BIOS which, coincidentally, was released earlier today. But the flash utility does not detect it as a valid BIOS. Quite odd, hopefully MSI will know more about that.

I say this because I have the B350 Gaming Pro Carbon motherboard. It runs everything I throw at it. It even booted 3600mhz with no problem. The Bios that is known to be very good is E7BOOAMS.1JO for my board. I think the bios may be the same. I saw the new bios released by MSI today. The last one was awful! I know it says beta but it was total garbage. This one is also beta. I may give it a shot.
