I don't think the cpu is often a bottleneck at higher resolutions, the GPU becomes much more important there IIRC

Alright well I’m still scratching my head over this but I’m gonna put this here in case it helps someone else. I posted before about my ASRock B550 board that worked fine for a month and a half suddenly developed the USB issue where the ports would randomly disconnect/reconnect. Usual fixes did nothing to remedy it. Well, my girlfriend has Firefox going with about a billion tabs open and set to restore them when Firefox starts, after clearing a bunch of them down to a reasonable amount the USB issue seems to be corrected, best I can tell is that’s the ONLY thing different and now it’s completely fine. Can’t say I even begin to understand why that did anything but if you guys are having the issue try closing your browser down or killing tabs to less than 20 open at a time and see if that’s the culprit.

The 3100 has the same clocks as the 3600, doesn't it? Probably not worth the upgrade unless you're playing something that really wants >4 physical cores.

The design has two distinct 4-core clusters. The 3100 has 2 cores in each cluster working. A 3300 has all 4 cores in one of the 4 core clusters working, with the other fully disabled. Functionally, this is faster because the cores don't have to reach over the slower fabric to the other cluster to talk to each other, and the cache is all sitting locally. As for whether an upgrade to a 3600 will help, I would take a gander at the GN charts and the games you play. It might make a difference, but at 1440p with a 1080, you are likely going to be GPU bound most of the time on new titles. https://www.gamersnexus.net/hwreviews/3580-amd-ryzen-3-3100-cpu-review-benchmarks-overclocking-gaming

I picked up a 5800x the other day. I know the thread advice for Zen 3 overclocking is "Turn on XMP, maybe set curve optimizer to -10, stop loving with it, " but, you can't tell me what to do, dad. So, I kept loving with it, and ran into a couple strange problems in the process. The first is that my memory controller won't do 3600 at any sane voltage. Not the 1.1 most people seem to do it with, not 1.25, not even 1.275 that I tried "just to see" but definitely wouldn't actually run 24/7. It just won't do it. Prime 95 large (actually custom with the large FFT sizes but set to use most of my memory) throws rounding errors in most threads almost immediately. 3533 works fine, though. At auto voltage. (The unsustainable chip murdering voltage that Asus feeds your SoC when you turn on XMP, which hwinfo reports as...1.08) Passes several hours of memtest and did 24 hours of Prime95 large no sweat. I know it's the controller and not the ram itself because I could do 3800 with dram calculator fast timings, but that only worked because this motherboard goes to UCLK=MCLK/2 once you go past 3600. ...which I didn't realize until spending a couple hours dicking around with timings trying to figure out how the gently caress I was getting 75ns latency in AIDA at 3800. If I drop to 3600 it gets expected latency, but it eats poo poo in any memory test. I'll just run it at 3533 and not worry about the imperceptible performance difference. But, I don't think I've ever seen such a sudden drop off like that when overclocking something. From fine at barely over stock voltage to "it boots, but doesn't actually work" with as much voltage as you'd ever want to feed it after only a single speed step. The second weird problem is that changing primary memory timings now makes the computer not boot. I can play with secondary/tertiary stuff all day but if I touch tCL, either tCRD, tRAP, or tRAS - even to make them slower - it's time to break out the screwdriver to jump the clear CMOS pins. This was an absolute bitch to troubleshoot that took me another couple hours, in no small part because it was working fine earlier. (I doubt this ram would do 3800 at XMP primary timings) I have no idea what would cause that outside of a UEFI bug, but that seems unlikely because...it was working fine earlier. I did, at least, figure out that this chip will do -25 all core curve optimizer with +50Mhz PBO limit. So I've got that going for me. It's only one core that doesn't seem to be able to do -30 so I could keep tweaking it but I'm kind of burnt out at this point. Anyway, that's what I ran into while spending several hours across three days chasing single digit % performance gains. Take this as a warning about not following thread advice. Or don't and see what weird poo poo you run into. Theris fucked around with this message at 15:52 on Mar 18, 2021 |

Truga posted:also, their GPUs now run up to 20% faster than nvidia on the same cpu if you're cpu bound in games. i have no idea what happened on the gpu side for that to happen but just big lmaos all around the overly simple answer is that the CPU still has to tell the GPU what to draw, even if its the GPU that has to draw it, and AMD's drivers are more efficient for whatever reason, so you can "get more work" out of a slow CPU feeding instructions to an AMD GPU, than a slow CPU feeding instructions to an NVidia GPU this is why if you're pairing a slow CPU with a relatively much more powerful GPU and the game is choking the CPU (say something like an FX-4100 combined with an RTX 3070), dropping the resolution won't help - it's so much simpler for the GPU to render a 720p scene so the GPU is just waiting to be fed instructions by the CPU, but the CPU already can't talk to the GPU fast enough between all the other stuff it has to do, so you get no increase in FPS. In cases like these, it's actually better to keep increasing the graphical settings and the resolution so that you shift more of the work back to the GPU (until you start seeing drops in FPS again)

Nvidia went to software scheduling during the DX 11 era because it allowed them to use the excess CPU power most people had (lots of multi-core CPUs while games remained single-threaded) to make the GPU more efficient. As a result, the Nvidia GPUs ran games of that era more efficiently. However, games are now much better about using multiple threads so this software scheduler eats into those cycles. AMD still uses a hardware scheduler on their GPUs so they don't run into this same kind of issue.

oh yeah that makes sense. i remember hw scheduler being a big thing back during early vulkan/dx12 days and people just went "nah, just buy a faster cpu" i guess that still works if you have a high enough budget for now

Or don't and see what weird poo poo you run into. Yeah that's RAM overclocking for you, I had all of those issues with my 3950X and it turns out it wasn't the RAM or the CPU limiting my overclocking headroom but the motherboard. I had the same issues with a 5800X in that mobo but they went away when I moved it over to a new one, now I can run 3800MHz 1:1 with the Ryzen calc fast settings which is much better than I could do with the other mobo. I also have to clear the BIOS if I try to gently caress around with it more beyond that so I just left it, not gonna mess with it for a month like I did with the 3950X.

I'm at 3733 mem / 1667 IF myself because 3800 won't POST (or won't stay stable for more than 1 minute) and this is really common.

Is Anand's review of the 5950X boosting to 5.1ghz backed up by other people or is it just a golden sample to a known reviewer? A friend has a 360mm AIO and ROG X570-E currently paired to a 2700X while he waited for zen3, and he has dreamed of a "5ghz Threadripper" since 2017. Since he's at the end of the AM4 platform, he wants a 5900X but with supply being as it is I've considered suggesting he step up to the 5950X because, yes, expensive, but it also sounds like the chip he's always wanted.

VostokProgram posted:Isn't the Infinity fabric only able to hit 1800 MHz? I thought that was why nobody runs ryzen ram above 3600 Zen 3 seems to be a bit better about going past 1800, including mine that seemed to be fine at 1900. The problem I had at that speed is that past 3600/1800 my motherboard halves the memory controller clock ("UCLK", not the infinity fabric which is "FCLK") which does horrible things to latency, and it doesn't have an option in UEFI to change that. Not that it matters, since apparently my memory controller can't handle 1800+ at full speed even if the fabric can.

Is this the right thread to ask about motherboards? After literally three months of having a RTX 3080 sitting in my living room, not plugged into anything, taunting me, I have finally been shipped a 5900x to pair it with. Now I need a rest of the computer. I have a PSU, I have 64GB of RAM that claims to be guaranteed for CL 16-16-16-38 @ 3600MHz, I have a nice case- I need a motherboard. I don't need anything particularly fancy, I'm not planning to overclock anything. A lot of SATA might be nice, because I have a lot of old HDDs lying around with stuff on them, but I won't cry if I have to ditch a few. Just the basics; ethernet, some USB, audio whatever, NVMe or M.2, not fussed, and a memory topology that is going to play nice with the RAM (4 sticks). Oh, and I guess I'll need a CPU fan. Anyone got one they like?
