I found out that AsRock X670E PG Lightning has all the daughterboard slots that I need (4 in total with GPU, Audio, NIC, and HBA) in a configuration that makes sense for what I'm trying to do (ie. not end up with lane sharing on devices which are meant to satuate as many of their lanes as possible). It's also a fair chunk less expensive than the Gigabyte B650E Aorus Master. Pablo Bluth posted:https://www.youtube.com/watch?v=TYOkJFOL5jY HUH. I didn't know these existed.

Yeah it's a pretty incredible board for value compared to the competition. There's a lot of plain-jane B650 boards that are still more expensive with half the features.

I swear to god if this loving machine doesn't stop hard locking randomly every 12-36 hours I'm going to go buy a 13700K. Never in my life have I had a platform so horribly unstable. It sucks because the 7700X is an absolute powerhouse when I need it to be but the fact that sometimes it'll even crash twice in the same day and no combination of BIOS updates/reseating RAM/AMD driver updates has been able to fix it is making me think something here is just hosed and I don't have time to deal with RMAing each part individually and being down while I wait for replacement parts to get back to Canada.

So in theory, if ECC-DIMMs ever get fast enough, I can replace the memory I plan on buying. I decided against the 4800MT 16G ECC DIMMs (since I couldn't find out if running four of them lets me overclock to 6000MT without wining the M-die lottery), but even outside of that use-case, just being able to buy a single ECC DIMM to confirm things is nice, especially because I noticed that the UEFI lets you control if NMEs are generated.

I don't use my PC for much more than gaming and browsing, so the general workstation task performance loss with the X3D variants doesn't matter much to me. I'm curious about streaming though, as I am on twitch a bit. Any reason to think the 7800X3D would be a bad choice for occasional streaming in a 1 PC setup? Currently have a 3900x, for comparison sake. It would be paired with a 4080.

2 dimms per channel works on Zen 4, but you will need to severely cut frequencies to get it stable. Officially supported speeds at 4x1R or 4x2R is DDR5-3600. At CL30, thats a 23ns first word latency lol. If you are doing anything except production tasks that require large amounts of ram and dont care about throughput/latency, you are much better off getting 2 dimms. Another reason why ITX reigns supreme!

Also worth noting that NVENC uses hardware that does nothing except video encode/decode on Nvidia GPUs so there's also that.

Honestly impressed with the gigabyte b650i aorus, it's been a while since I've built a new PC but man I couldn't imagine an easier bios flash, maybe it's the standard on newer PCs, but literally just unzip, dump on drive, plug it in, press bois flash button, and done 30seconds later. I've read a lot about memory training shenanigans, first boot seemed to be a bit long, maybe 4min but that's it so far. *Knock on wood*.

The roadmap for DDR5 does include up to 128GB dual rank UDIMMs, but we are likely years away from that. The only way to get 128GB on AM5 today is with 4x32, which means you are forced to roll the dice with speed limits. It seems most of the compatability issues are ok now (at launch, 128GB did not work at all on many boards), but the speed is a different story. FWIW, I came across a few Reddit posts claiming that the new 48GB sticks actually offer the best compatibility/speeds in 2DPC mode, perhaps even running at 5200MT. Still not....great, but could be much worse.

Here's the Anand article on when 1DPC vs 2DPC can - the take-away being that unless you're doing memory-intensive workloads (ie. not gaming, the opposite of what the X3Ds are best at), it doesn't really seem ilke it's gonna matter? EDIT: That doesn't cover EXPO/XMP speeds, though - which is where it might introduce real issues? Speaking of EXPO/XMP, if a DIMM says it supports XMP, does it mean it supports EXPO too?

BlankSystemDaemon posted:I went with the 2x32GB for my build because I'm hoping that eventually we'll see UDIMM with not just on-die ECC but real-ECC at some better speeds. Yeah, for DDR5 in particular, 2x2R is superior to 4x1R at the same clocks based on what I've seen. 2x2R also lets run much higher clocks, in general. I think it was Wendell who said its best to consider Zen4 a single dimm per channel platform except in specific use cases, and thats probably a good way to think about it. EXPO is a slightly different standard than XMP, as EXPO includes more subtimings. But all the AM5 boards I've looked at so far support both standards (it may have a different name in the BIOS to avoid royalties, like ASUS and DOCP). I looked pretty quickly and it seems prices for GSkill specifically between the Z5/Ripjaws vs Z5 Neo/Flare (XMP vs EXPO) are pretty close, anywhere from zero to $15 different at the same timings. If it was me, I think I would consider spending the few extra bucks just for the ease of not dealing with those subtimings.

Their newer 7xxx GPUs do have a AV1 encode/decoder. Its supposed to be pretty good actually and is comparable to the Intel or NV AV1 support overall. The 6xxx GPU's had it too but it wasn't as good as NV's or Intel's. Wasn't exactly bad either though but some people like to blow things out of proportion.

The thing with this card is that it is an order of magnitude more efficient than gpu encode/decode (35W for 32 simultaneous 1080p60 decodes!) while also producing higher-quality encodes with just 2 - 8ms of latency. EposVox talks a lot about the usefulness of these features for home users or small independent operations, but i feel like the dual-asic card is a bit overkill for those purposes. I wonder if AMD would create a single-asic version at an even lower cost for home users. Also, I'm not sure how much encoding latency factors into the wider latency picture for cloud gaming, but I wonder if this could help make that more responsive.

From the diagram they showed, it seems like each ASIC has four encoder units, two of which support h264, h265, and AV1, and the other two of which support only AV1. They use two of the same ASICs to double max throughput I guess, so one should be capable of all the same things as two, just with half as many possible simultaneous operations.
