Important though: When trying to figure this out, don't open up the power supply itself, even when it's off and disconnected from the wall! Opening power supplies up, for whatever reason is a pretty big "Only if you know what you're doing" thing, and capacitors inside the power supply can charge up with enough energy to be dangerous if you accidentally touch where you're not supposed to. Does this happen only when plugging in or during regular usage? (Especially the lights flickering) Out of curiosity, can you give a bit of info on the PC? (power supply, main components like CPU and GPU) Also is your electricity 110V or 220V? Thanks

Thanks! I have 3000 MT/s RAM (CL16), I expect that would be reasonably fast enough? I also checked the motherboard and I'd need a BIOS update but there is support, Thanks!

Funny enough it's more expensive than the 5800X right now (locally), and I didn't even know that it existed until now. (Because it's only available boxed and the 5800X is available in tray) Is there any advantage to it? EDIT: it looks almost like it's just a 65W version of the 5800X so I guess I can compare it to the 5700G to see how much the cache difference makes. Thanks

Hi, I've currently got a Ryzen 2700 (Zen+) CPU in a Gigabyte B450M DS3H motherboard. For the most part it's doing it's job well enough for me (I do mostly what would be considered specific productivity tasks and until now my gaming as been limited to 60Hz monitors, non-competitive). In the next few weeks I'm making some changes that I think might change that though: I'm buying a higher refresh rate monitor and a VR headset, so I expect the Ryzen 2700 might not be as great going forward. I've got an opportunity to upgrade now at a slight discount, to either the Ryzen 5700G or 5800X (both effectively similarly priced, the 5700G is slightly cheaper locally but negligibly). Both with 8 Zen 3 cores. I know that in general, the 5800X is faster than the 5700G, but thinking forward I do have two uses for the integrated graphics that are a nice-to-have: (but not mandatory) 1) I use Linux sometimes and it would be nice to be able to use the iGPU for the AMD drivers in Linux (nice but not a must, right now I use my nvidia GPU and it works, just a bit janky sometimes when I also run large CUDA workloads on it) 2) In the future I would like to repurpose this hardware as a server or media center once it comes time to upgrade to a completely new computer, and having an iGPU would make that easier. But this alone isn't enough to justify the 5700G over the 5800X if the performance difference is huge. (If I get the 5800X, I can survive with the Nvidia drivers in Linux and buy a cheap GPU when the time comes to retire this system to a server.) So my question is, how big would the performance difference realistically be in a power constrained system? The B450M DS3H motherboard doesn't have the best power delivery (at least, when running Prime95, the CPU only got 75.6 W package power maximum according to CPUID's Hardware Monitor), and my power supply itself doesn't have a crazy amount of headroom either. Given that, I'm not sure how much of the difference between the 5700G vs 5800X would be in my system. I know that some of the performance advantage of the 5800X is the larger L3 cache, but it is also rated for a TDP of 105W vs the 5700G's 65W TDP (on paper) and Anandtech reviews show that the 5800X draws up to 141W peak vs 88W peak for the 5700G, so I wonder how much of the performance delta is power envelopes (which I think I won't be able to benefit from anyways) vs the cache/SOC architectural advantages. If anyone has any ideas or insights I would be happy to hear them, Thanks!

IBM and Sun (back in the day, not sure if Oracle continued with it) had wider SMT processors in their PowerPC and SPARC architecture lines. I'm pretty sure it went up to 8 threads per core for at least one of them, but I don't remember for sure. (It's possible they even went up to 16 threads but my memory could be playing tricks on me). The thing is, such wide SMT is useful in some tasks but can require engineering tradeoffs that make the CPU worse in other tasks. On a very technical note, I'm not 100% sure if the SPARC implementation was actually SMT or a multiplexing (sometimes called "Fine Grained") in-order engine implementation. The point is, not all cores that run multiple threads on a single core are actually SMT, but back to the point, the Intel and AMD implementations are both similar and do SMT execution.

Thanks!

Yeah, that's why I reduced the memory speeds already and loosened the timings. There's nothing more annoying than a crash right at the end of running a 10 hour simulation (which is when I was experiencing most of the crashes, probably because of a lot of memory usage). So as long as the channels are balanced/symmetrical, it should remain in dual channel? But maybe with a speed reduction required?

Hi, I've got a system that I built a few years ago for a mix of work and some gaming (not sure I'd call it light, but not very heavy/competitive either). On the work side, I've reached some RAM bottlenecks with 32GB of RAM where some workloads just pass the barrier of needing more memory and result in thrashing (when memory pages have to be moved to virtual memory to allow for other pages to be loaded to RAM, but then immediately after also are themselves required and then are pulled back into RAM instead of another memory page - It's significant, because simulations that don't cause thrashing scale pretty linearly with the amount of data, but then just 500MB more in a simulation can cause it to jump from 2 hours to 15 hours because of it). Because of this, I've been considering extending my RAM capacity to 48GB or 64GB, but 1) the kit I originally bought is no longer in stock locally, and 2) even with just my kit, I've had occasional stability issues (not sure if due to the RAM kit, my CPU or my MB), and therefore I'm warry of making things worse. Even as things are, I've softened the "overlock" in the XMP profile a little (I run the RAM at 2933 MT/s instead of 3000 MT/s and with less tight timings) to improve stability. 3) I'm not 100% sure about the different rules when it comes to non-kit RAM configurations these days with modern CPUs So first of all, the build's current relevant specs: CPU: AMD Ryzen 2700 (I'm planning to upgrade to Zen3 further down the line, but I assume the memory controllers will be better on Zen3 so it's not a problem) MB: Gigabyte B450M-DS3H (CPU-Z shows it as B450M-DS3H-CF. I know it's not an amazing board, but at the time with my needs it was reasonable) RAM: ADATA kit of 2x16GB - 3000 MT/s with timings 16-20-20-38 - I don't actually have the full kit product name, it's not on the receipt because the store gave me the wrong product, and we sorted it out on the phone after so I don't have a paper-trail, and it's no longer on their website 2.5 years later. The things I can see from CPU-Z include that each stick is dual-rank, and that the modules themselves are manufactured by Micron. [Other than that I have an Nvidia Geforce RTX 3060 Ti FE, an Intel 660p NVMe SSD and some mechanical hard-drives over SATA] Given that, here are my questions: 1) Will adding more sticks of RAM potentially decrease my stability even further? Especially if not made to the exact specifications? (I know it will run at the speeds of the slowest RAM pair) 1.1) Will I have to reduce the speeds of my memory further to overcome that, further than the slowest stick's speed? (I mean both bus frequency and latencies) 2) Is there a problem adding more RAM considering that the sticks I'm using are dual-rank already? Can the Ryzen 2000 (Zen+) memory controller handle 3 or 4 ranks of memory on a channel/6 or 8 ranks in total? 2.1) Is there a problem mixing dual rank and single rank sticks in the same channel? 3) I know in the (far) past (at least on Intel platforms at the time), mixing RAM stick capacities and maintaining dual channel was possible as long as each channel was identical. Is this still the case? Can I run 16GB+8GB per channel if I add a 2x8GB kit and maintain dual channel? Is this ok on Ryzen 2000 platforms? 4) Is there any significance to getting another stick with modules from the same company? In my case, Micron modules? Thanks in advance

Isn't ATX12VO mostly for OEMs? But I do get your point, and I guess now thinking about it, even if some cards will require the new standard on the next-next generation (ie RTX 50xx) some AIBs will probably make an adapter or version that doesn't to capture the market with older PSUs. Thanks

Hi, I'm assisting a friend with some part decisions for his new PC. When he was originally specing out his parts a few months ago, his requirement was that he'd be able to use the computer reasonably for a very long time (on the order of 7 years) without many changes (he expects to upgrade RAM capacity and GPU somewhere towards the middle). Given these requirements I recommended he go for a good quality PSU with more headroom, because it was also when rumors of the next generations of GPUs being more significant power guzzlers, especially at the high end. He chose a Tier A PSU: be quiet! STRAIGHT POWER 11 1000W Platinum With the assumption that such a PSU would be an investment for the life of the system and "hopefully the next one too". Since then the new ATX spec has come out (but no new PSUs using that spec to my knowledge) which includes a form of the new 12+4 pin PCIe/GPU power connector (12VHPWR) with a smart negotiation mechanism for power management and my worry is that I haven't yet seen any information about backwards (or forwards?) compatibility. I'm talking about this spec: Is there any info to suggest that today's PSUs will be able to power graphics cards that implement the fancy new 12+4 pin spec? (For instance with a simple adapter similar to the one on the RTX 30 series FEs.) Or is it possible/likely that this change would necessitate a brand new power supply anyways 2 generations down the line and therefore overbuying now is just a waste. The parts he went for: CPU: Intel i7 12700K on a Gigabyte Z690 Auros Elite AX DDR4 motherboard with 32GB of DDR4 RAM at 4000MT/s GPU: RTX 3080 And a Samsung 970 Evo SSD + Seagate Mechanical HDD, all inside a Fractal Meshify 2 case. In theory a decent quality 750W PSU today should be able to handle that, which is why I wonder if the "futureproofing" is worth it in this case given the potential changes. Thanks

I wouldn't take that risk anyways. I don't know if PSU manufacturers test sample units off the production line and then package them, and I don't know what state they'd be shipped at in that case. Unless you're 100% sure it's been on a shelf for months, it could have been air-shipped to the distributer to close gaps (rare but happens) just days before after testing at the factory, etc ... Point is the probability of it being safe if it's brand new is high, but I wouldn't take any unnecessary risks with power supplies like that. Always treat a power supply's internals like you're supposed to treat a firearm: Never do anything assuming it's not loaded. (That is, never do anything with it you wouldn't do if it were loaded.)

I just saw the LTT video about the linux challenge, part 1, and saw the same thing happening to Linus. Are you asking this question because this happened to you or because you saw what happened in the LTT video and want to avoid having the same thing happen to you too?

So I assume that means I need an upgrade? The prices here are a bit lopsided but looking at the local prices and the tier list, I have an option that I think is the Antec EarthWatts 750W 80+ Gold EA750G PRO (I think this is in Tier A) at a somewhat similar price to the Corsair CX750F and not much more expensive than Corsair's CV650. Between those, anything I should avoid?

One of the more reasonably priced options that I think is on the Tier A in the PSU Tier List (but I'm not sure, because everything else at the same price point seems to be in Tier C or D and the same or similar names seem to be reused by the companies for seemingly completely different classes of products) is the: "Antec EarthWatts 750W 80+ Gold EA750G PRO" (The link on the store page links to this PDF in English: https://www.antec.com/documents/product/EA750G_PRO_Manual_EN_20171025.pdf ) There's also a Corsair CX750F at a bit more money or the Corsair CV series at a bit less (but only 650W). Everything else is much lower on the tier list or more expensive.

No, the only model from them that seems to be available is called "Pylon". (There's also a Gigabyte unit available that I missed last time looking, but I'm pretty sure it's the infamous Gamers Nexus tested explody one)
