UPDATE: There was a problem with my CPU. It stopped working suddenly after around 6 months of use. Computer would not turn on whenever RAM was in dual-channel mode. Tested the CPU in multiple motherboards and DIMMs to confirm that the problem was indeed with the CPU. I sent it back to the store where I bought it and they confirmed the issue and sent me a new R9 3950X. So if you found this on Google because you're running into the same issue, I recommend you RMA your CPU right away. Haven't run into the same issue with my new Ryzen 9 3950X yet!

Have you tested each RAM stick individually in the slot that works? If all the DIMMs work, it's either the motherboard or the CPU. It sounds like you purchased the parts recently. I'd waste no time in returning the mobo and the CPU. I'm currently having the same issue, but with an AMD CPU. Happened suddenly after months of use. No bent pins. I was able to boil it down to the CPU by testing it on another motherboard (problem persisted) and by testing another CPU in my PC (problem went away) If you know anyone with a compatible CPU and motherboard that you could use to test your parts, go ahead and do so. If you don't, return the mobo and the CPU as soon as possible! Sorry you're going through this on your first build and I hope this doesn't discourage you from building pcs!

@Finessed. So was it the motherboard? I'm running into a similar issue right now. Computer shut off randomly and wouldn't turn back on. Tested all ram sticks individually on slot 4 and all of them worked. Computer would never boot if I had any DIMM in slot 1 and 2 though. Let us know if the new motherboard worked out for you!

Spoke too soon Happened twice in a row. I think I'm going to RMA my CPU before it's too late.

Solved the issue! Downloaded the chipset drivers directly from AMD's website as opposed to from Asus's page for my mobo. Asus's supposed AMD chipset driver download is a load of garbage as far as I'm concerned... You download it and unpack a bunch of unintelligible folders with random files and .exes. The chipset drivers I got from AMD actually has one .exe that installs everything you need. That being said, the chipset update installed AMD's Ryzen Power Plan, which I think is what took care of the issue. I believe that's it. I'll report back if it happens again. Thanks @Syn. I also started using HWinfo instead of HWmonitor. It's reporting a higher (and more believable) voltage, so I see now why everyone says HWmonitor is unreliable.

Thanks @Syn. I'll take a look at all the things you mentioned. So far I haven't had the cores get stuck at 533Mhz again.

That's definitely too high. What cooler are you using? Are you sure you didn't forget to remove the "REMOVE ME" plastic from the cooler? Not judging... I've done that once

Thanks Syn, minimum processor state was already set to 100%, so although this is closer to the issue, I don't think this setting was the cause. That would make sense if the computer wasn't noticeably sluggish while these cores were stuck at 533mhz. I'm not the expert here, so it's possible that I'm very wrong, but as far as I know clock speed is independent from CPU load (as in, right now, my PC is idling at 4.3GHz with 0 to 1% utilization, as it should). Unless, of course, clock speeds are lowered to protect the CPU from overheating or over voltage, but I don't see why a CPU would underclock when in low load other than for power saving purposes. Given that the computer is set to high performance plan, it's a bit baffling that the underclocking is taking place.

Hi there. I recently upgraded from an R7 2700X to an R9 3950X. Main purpose of my computer is CPU rendering with V-Ray, so I was really happy at first when I was getting 4.3GHz automatic boost clocks while doing light work and 4GHz all-core when rendering--at incredibly lower voltages too comparing to my 2700X. Temps won't go above 60 degrees C while all core rendering at 4GHz, which is really impressive. I intended to keep clocks unlocked and let the computer control the optimum speed for the workload, but today I was noticing some sluggishness while doing basic administrative work like emailing and saving files on Photoshop. I fired up HWMonitor to see what was going on and noticed that all cores were boosting randomly, except for the first 4 (core 0 through 3) that were stuck and wouldn't go past 533 MHz (??). This is not the first time I noticed this behavior with this new CPU. Last time a simple restart took care of the problem. However, I can't afford to stop everything I'm doing to restart the computer every time this happens. For now I quickly locked the clock speeds to 3.7Ghz in the BIOS just so I can keep working. The "snappiness" is back, but I would REALLY rather leave the clock speeds automatic to get the full benefits of having a 3950x. So, is there a way to let the CPU boost automatically, but not let it go below a certain clock speed? Does anyone know what might be causing this issue of a few cores being "stuck" at low speeds? I'm a bit of a noob when it comes to knowing what all the settings and knobs do in the BIOS. My mobo is an Asus ROG Strix X470-f, BIOS is updated to the latest version, cooler is a Cryorig R1 Ultimate. Windows power mode is set to performance. "Asus Optimal" does exactly nothing in the BIOS for me (under EZ System Tuning). Thanks in advance! FEB 2021 UPDATE: There was a problem with my CPU.

Actually, I think I'm going to partition my current 1TB NVMe drive and use part of it as cache for the HDDs: https://www.romexsoftware.com/en-us/primo-cache/instructions-manage-l2storage.html

Thanks @Kilrah. I'm looking into it and I think I'm going to leave my current NVMe as is, get another one but 256GB and tier it with 2 4GB HDDs using PrimoCache -- this is where I will store all projects and assets. I'll then use Window's automatic backup to back these files onto my NAS. NAS will have 2 6TB drives in SHR. I think this way I'll get the best of both worlds... Speed and security. Right now I have neither. I did the irresponsible thing and have been running my NAS in raid 0 for the past 3 years. Luckily nothing bad has happened, yet!

That's true. That's what I end up doing when working on heavier projects. I should have also specified that I also enjoy the larger capacity of the NAS and it allows me to keep all the projects organized in one place. Right now I have a 1TB SSD on my PC and about 9TB on my NAS, half of which is filled. Edit: Perhaps I'll change my setup. Maybe use StoreMI to combine the speed of my SDD and the capacity of a HDD, and then us NAS strictly for backup.

I have a DS418j that I use to store projects and assets for 3D animation. The reason why I'm using a NAS instead of local storage is because the files need to be accessible to another computer for network rendering. The downside of this setup is that things like project loading speeds are considerably slower than if I were to store everything locally on my NVMe SSD. So I was wondering if there is an easy way, or a way at all, to allocate something like 100 GBs locally on my PC to cache the most used files from my Synology NAS. Thanks!

I mostly use my computer for work. 3D rendering/animation and arch viz. Although I love games, I've been playing less over the past few years. When I do play, I get hooked on Civ 5, Hearts of Iron 4, and driving and flying simulators. The only AAA game I buy/play when it comes out is Far Cry. Cool co-op campaign to play with the wife.
