Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Intel truly adores crippling their products. Hopefully not the case for the 2k USD 18 core / 36 thread i9-7980XE... https://arstechnica.com/gadgets/2017/07/intel-core-i9-fastest-chip-but-too-darn-expensive/ …pic.twitter.com/RyppeALnyL

      They seriously expect people to pay 1k USD for a CPU where they were too cheap to solder the heat spreader to the processor... that's awful.

      That's terrible, but taking the stock heatspreader off (decapitating) isn't new for the overclocking community.

      These are expensive products specifically aimed at overclockers. Taking off the IHS from a $150 CPU is a whole different story than 1k USD.

      They're specifically listed at https://www.intel.com/content/www/us/en/gaming/overclocking-intel-processors.html … and unlike quad core K series there's no way to adequately cool them w/o delidding.

      There's something very wrong with needing to tell people that they should be using liquid cooling even for stock clock speeds...

      71C delta between CPU and IHS is insane. Almost no overclocking headroom on these without taking off the IHS. They haven't done this before.

      I'm rather surprised someone with your attention to security would be into OC stuff. I'd think you'd underclock for added robustness. ;-)

          Caring about robustness just means being conservative: higher voltage than strictly necessary and better cooling to compensate for it.

          OEMs often sell desktops / laptops with inadequate cooling / PSUs, where running mprime's stress test will force shutoff or overload PSU.

          A real security issue is that unlocked core multipliers, ratio limits, offsets, etc. means that real root could brick the CPU via the MSR.

          Have far bigger concerns than losing the cost of the CPU if an attacker gets real root or less than that though...

          Used i5-4590 for building CopperheadOS and was terrible. 120m->25m for clean builds with i7-6950X @ 4.3GHz, similar for incremental builds.

          Intel doesn't feel like selling high clocked, high core count CPUs with high TDP so OCing is the only way to get that out of what they sell.
