Huh, I've generally seen that the one good thing about homes built in the last 20-30 years has been ample circuits. You want to see a whole lot of rooms working off a single 15a breaker, try living in an old house.

I just went through this in my 63 year old house - the microwave was on the same circuit as the whole living room, so if you wanted to use it while you ran the vacuum cleaner, oops! The breaker would trip! We had the panel redone and brought up to code, and a dedicated circuit added for the microwave, and things are generally a lot more stable and predictable now. If only the power company would do something about the haggard-rear end power line outside my house... Also, what's up with Intel and SiFive? I expected news about the P550 board last summer, what mayhem has ensued in RISC-V land?

Intel announced a new product roadmap that includes a 14A node, the first to use high-NA EUV machines: https://www.tomshardware.com/pc-com...emains-on-track There are some other interesting bits of info in the article. quote:Five nodes in four years remains on track.

repiv posted:https://www.radgametools.com/oodleintel.htm What's the preferred burn in tool to test if CPU/RAM are actually stable these days? There's no way that it's Prime95 anymore, right? Also, is Epic telling people to turn their 6ghz processors that they paid very dearly for down to 5.3ghz, a more than 10% loss? I really want to know what's actually going on, do i9s need top-end mobos with a hundred power phases? Are they pushing all-core turbo too high out of the box in a misguided attempt to win benchmarks? It power and cooling a contributing factor? And finally, I just want to scream at motherboard vendors for defaulting to overclocked settings out of the box, and having to find and change 4 different settings just to run a processor at stock. Why isn't there a single switch for "Run it like Intel validated this 6ghz thing". Intel should be policing their own ecosystem, it's insane that apparently a large number of different motherboards will be unstable with your new shiny i9-14900K.

This all reminds me very much of the AMD x3D scandal from a little while back where several vendors, and particularly Asus, were caught juicing power carelessly and ended up setting SoC voltage high enough to cause progressive degradation in the space of a few months. There’s a lot of benchmark goosing predicated on strategies - which presumably worked on 14nm - which break down as these chips become engineered to tighter and tighter tolerances. The chips are the stars; the motherboards are commodity products trying to stand out against each other in a saturated market, and outside of pulling in novel features which cost more to implement and impact asking price, it seems there’s less and less room to do that without impacting CPU longevity or system stability.

The AMD mobo vendor SoC voltage thing was likely so that RAM would be more likely to boot at all at advertised XMP settings.

I still like good old prime95 & memtest, because while they're not perfect these days they're at least definitive when they detect a failure. Add OCCT for whole-system stress testing both CPU and GPU at the same time to test power and overall stability. poo poo is so complex now, and so many of the recent bugs have been "well this one specific operation under these conditions is a problem", that there's no one tool that can prove your system is stable. Twerk from Home posted:Also, is Epic telling people to turn their 6ghz processors that they paid very dearly for down to 5.3ghz, a more than 10% loss? They're telling people to turn down their 6ghz processors to prove that it's not their fault, it's the processor that's hosed. From there you have to make your own decision -- live with a 10% loss on a CPU that you paid dearly for, get a refund, or do RMA exchanges with Intel until you get a non-faulty CPU.

Worf posted:doesnt intel sell locked processors still The type of overclocking that these boards do all still works on locked processors, I'm sure that if a 14900K is doing it in a board, a 14900 will because they're cranking up the all-core turbo and PL2 power limit to the moon. Same with memory overclocking, you've been able to do memory overclocking with locked processors for ages, right?

"As defined" for Intel's turbo on K processors is very fuzzy. Turbo is "we'll run at 6ghz as long as the motherboard can deliver the juice", but the spec for socket power is based on what a non-K CPU can use, so there's some negotiation involved. (This is not unique to Intel, though AMD has much less slop these days because they're shoving enough electricity into a CPU to do a DBZ power up montage.)

Worf posted:it doesnt seem logical that a locked CPU would prohibit XMP profiles on RAM to me tbh But you're overclocking the memory controller, and it doesn't just allow XMP profiles, you are able to punch in arbitrary clocks, timings, and voltages well beyond JEDEC, while JEDEC support is ostensibly what Intel is selling you. Buried in the extended documentation for these processors is that if you buy a 14900K and DDR5-6400 RAM and it just doesn't work, you can't warranty that. Intel's spec sheet says that the 14900K supports DDR5-5600 in 1DPC configurations, and DDR5-4400 in 2DPC configurations, at JEDEC timings. Maybe you get lucky and can support faster than that, but it's not on the spec sheet and instability isn't Intels problem if you go faster. We're just clearly at the point where overclocking is the norm, and mobo / RAM vendors are pushing things well past the realm of stability with the hopes that working "most of the time" will be good enough for their customers. I just wish there were an easy way to opt out. Edit: Just to highlight another different pile of poo poo in this mess, Intel enabled dynamic memory overclocking a few generations ago: https://www.anandtech.com/show/16959/intel-innovation-alder-lake-november-4th/4  I will guarantee you that some motherboard vendors have this on by default, meaning that you've also got RAM dynamically increasing and decreasing its voltages and clocks based on load, and loving it up such that it causes problems.

The weirdest thing about the BE200 is how vendor specific it is. You can literally use basically any Intel processor ever, I saw someone testing it with (iirc) Nehalem and it worked but you can't use it with any AMD CPU ever without it failing to POST.

I have an IBM Power9, if anything’s far afield from presumed Intel compatibility I’m probably covered. I’d need an adapter because the machine’s hooked up to Ethernet and doesn’t use WiFi or Bluetooth for anything, but if someone wants to loan me the chip and a PCIe adapter I’ll report back.
