• The new class of vulnerabilities in Intel processors arises from speculative technologies that anticipate individual computing steps.
  • Openings enable gradual reading of entire privilege memory contents of shared processor (CPU).
  • All Intel processors from the last 6 years are affected, from PCs to servers in data centres.

    Well personally, I’ve been having a bear of a time trying to get my Ryzen machine to run correctly. I’m starting to think there just aren’t good options

      I’ve had numerous Ryzens, with 0 issues.

      Fewer Epics, but no issues either.

      What issues are you having?

        Frequent crashing/freezing, especially at idle. Once the processor is under heavier load it’s fine, it’ll keep going smooth for hours. but at lower energy states the CPU is super unstable. It often takes me about a half hour just to get the thing up and running steady, very frustrating. Sometimes it likes to crash right as it’s changing load levels/c-State, so just as it finishes loading files for a game just as the first 3d frame is rendered. Or vice versa, it’ll crash about 15 seconds after the computer returns to mostly idle when you exit an application.

        I’ve tried a bunch of things, disabling c-states, manually setting dram timings, manually increasing power to various parts, enabling/disabling just about every relevant feature I can find. And of course looking for help online. I’m actually pretty sure the problem is in the motherboard, as one of the “fixes” I tried was going from a Ryzen 3600 to a 3800X, and the problem was the same.

        I’ve looked around and it’s an issue I have seen other people having, though it’s not very common. But there’s no consensus in the root of the problem. It does seem to be that it’s some interaction between the motherboard and cpu. It could plausibly be the power supply, but I think that’s pretty unlikely. The ram is fine.

          I don’t know if amd does this for your specific issue but you might have a problem had with amd driver conflicts, I had this issue and was going through great lengths to Tey and figure out what was causing this until the helpful people at toms hardware helped

          https://forums.tomshardware.com/threads/sporadic-bsods-in-windows-11-professional.3877530/#post-23472239

          Edit: also try turning off memory context restore and there was something about ram power levels thst might cause bsods of similar nature to other people but I don’t remember the bios setting name at this time unfortunately but am just leaving this here incase you figure out the name

          I’d also recomend making an account snd posting on tomshardware forums because they helped me figure out what was causing my own BSOD’s

          And run memtest86 and memtest86+ just to rule out bad ram

          Windows ram diagnostics is useless

            I really dislike how you’re so comfortable recommending RMA’ing a board when the person hasn’t provided logs / data

            Because that does nothing to solve the problem if it turns out that an RMA wasn’t needed

            Tech troubleshooting is a process of ruling things out and reading through information to narrow down to a probable cause and implementing a fix too see if it fixes the issue

            You have no information besides what they’ve already tried which is random things because they haven’t read log data or other information to help them figure out a cause

              I have to admit I didn’t read it through properly, but if it’s a problem with two CPUs then it’s probably a motherboard issue. (Or something g completely unrelated like ram)
