The nice thing about old CPU coolers is you can put them on the back of big COB leds for DIY blinding devices.

I'm sure it will drop fast.

I'm only using the software on an older RX580 but it has a Record & Stream section in the tabs at the top, and selecting that shows a subset of tabs under it with Settings. In there you can configure where to save videos, what to include (desktop, audio, mic, frame rate, etc) and then on the right side there's Instant Replay which when turned on can be set to save the last X seconds, the default is 60.

Even better, you can do custom lengths - what I've done is figure out the maximum size that can be written to my SSD in 1 second, and set it to just under that (which works out to ~4 minutes of AV1 at 1080p@60fps, but it'll be different for you). Then I use avidemux to cut the video to length at the appropriate keyframes (which it can do without reencoding, to upload to YouTube), and optionally two-pass reencode to a target file-size and downscale it to 720p@60fps H.264 (to inline it on Discord).

I would check and make sure you can actually record video first. I was never able to get video recording to work in Adrenalin until https://www.amd.com/en/support/kb/release-notes/rn-rad-win-24-2-1-helldivers-2

On my 7900X, my understanding is the 64MB of L3 cache is split across the 2 CCDs. If a game (or application) doesn’t load cores across both CCDs, is the full L3 cache still being used?

If a game (or application) doesn’t load cores across both CCDs, is the full L3 cache still being used? It is one cache, but some effort is likely made to keep stuff on one CCD from getting into the cache on the other CCD. If an application running on one CCD has something in the cache on the other CCD it will have to pay the latency and bandwidth penalty to retrieve it. The full cache can be used even by a single application, but there likely isn't much benefit from going over what fits in the local CCD.

The full cache can't really be used by cores on one CCD, at least not in any beneficial sense. Going to the other CCD is as slow as going to RAM, it's only an option at all because it's necessary to maintain cache coherence. A 64MB cache AMD CPU is really best described as 2x32MB.

With the important note that this does not apply to all AMD CPUs. It's a large part of why some prefer the 7800X3D over the 7950X3D.

In my ideal world of them saying "2x32MB" or "96MB+32MB" we'd also be saved of all the dogshit articles saying "You could install your operating system in cache now!" because AMD markets Genoa-X as 1.152GB L3 instead of 12x96MB.

some rumors are suggesting that Zen5 is having a rough bring up and will launch later than originally expected. Su has a Computex keynote on June 3rd, which is def gonna be some sort of Zen5 announcement (along with AI AI AI AI AI), but dunno if we can expect that to be an actual product launch for desktop.

That is, the only way a line ever ends up in L3 is if it was first evicted by one of the local cores. The other CCD can read from the cache, but only for coherency, and this is not much faster than reading from main ram.

Josh Lyman posted:Would it make sense to think of my 7900X as 2x 6 core CPUs rather than 1x 12 core? If so, is Intel’s P+E architecture better about this type of thing? Intel's P+E architecture in client chips has a single L3 cache, yes. However, Intel's setup has its own big problems with caching, coherency, and inter-core bandwidth. When the E cores wake up it slows down the ring bus, slowing down how fast the P-cores are able to access L3 or memory: https://chipsandcheese.com/2021/12/16/alder-lake-e-cores-ring-clock-and-hybrid-teething-troubles/. Also, the E-cores share an L2 cache but have to synchronize through the L3 cache, meaning that core-to-core latency is worse for E cores that share an L2 cache than P-cores with each have independent L2 caches.

Subjunctive posted:wait, Zen 5 already? christ, Lisa, take a breath Literally exactly the same memory controller as Zen4. It's using the same IOD. The core is internally much wider, based on compiler cost model patches posted by AMD, but everything uncore (past L2) is the same as in Zen4. Subjunctive posted:I just want 32x4 at EXPO without worrying about my BIOS revision! Unless your sickness is very strong, if you already have Zen4 maybe hold on until Zen6. It's expected to come quite soon after Zen5, because it's supposed to use largely the same core, but with entirely new uncore/memory controller, using some fancy new way of integrating the dies.

This was fixed in Raptorlake. E cores and P cores are definitely better able to work on the same data than multi-CCD AMD, nothing you mentioned comes close to the cross-CCD penalty. It just turns out that as long as your CCX is large enough and your memory is uniform, you can just have NUCA without it really mattering too much for a lot of workloads. Cygni posted:one of MLIDs rumors was that AMD was pushing board vendors to certify this summers X870 boards (if they end up shipping them, it seems questionable) up to DDR5-8000, which which would still require you to go to 2:1 mode on the memory controller and will likely perform worse across the board with single CCD CPUs. 2:1 mode is faster than 1:1 mode for gaming when properly configured, even for single CCD CPUs (which you treat all AMD CPUs as for gaming). Running FCLK:UCLK at 1:1 is a large latency decrease and gaming performance increase, just like it was for AM4 era Zen CPUs, but you normally lose too much memory bandwidth to make it worth it. DDR5-8000 means you can run 4000:2000:2000 (MCLK:UCLK:FCLK), letting you still saturate your GMI link on bandwidth while providing lower latency than 1:1 mode.

BZ doesn't believe in FCLK:UCLK sync being a thing at all despite it empirically showing benefit, he's repeatedly said in the past that there is no also reason to maintain the 2:3 ratio that AMD recommends but you can microbench it making a measurable difference in latency. I love a good opportunity to bring out my favourite infographic:  Aeryn didn't even hit 8000, only 7800, but you can still see it wins at everything. Dropping your FCLK to 1950MHz only loses out to the 2200MHz config in one test, because the bandwidth microbench is purely a GMI bench, so you can see the benefit of UCLK:FCLK match. You're still only looking at a 136.20/127.29 ≈ 7% mean performance increase over just using DDR5-6000 with buildzoid timings, lol.

It is still better to run higher FCLK than 2:3, but only if it's a good few straps higher. I'd either fiddle around finding the highest you can run, which will typically be in the range [2133,2200], or just drop back down to 2000.

Users who might want some advantage from overclocking but don't want to manually oc for funsies should just use the buildzoid timings. Despite him being wrong about a few things, his DDR5-6000 timings are highly compatible with Hynix kits and provide a tangible benefit over stock DDR5-6000 expo. There seems to be a bigger gap between buildzoid's timings and EXPO timings than there is between buildzoid timings and the DDR5-7800 config.
