  • It finally feels like recent microcode updates have improved RAM stability at and over 6000MHz. I was an early adopter of the 9950X3D with an X870E, and it’s been a slow and painful wait while stability issues were worked out over this last year. (Since I migrated to AMD with a 7950X3D, memory training has always been hit-or-miss. Usually a miss unless starting from cold boot.)

    Realistically, there isn’t a huge benefit for RAM speeds over 6000 for now, but I can say with confidence that AMD @ 6000 being the sweet spot may be finally in the past. Hopefully. Maybe. (I am running a Crucial 6400 64GB kit now with some tight timings and a mild overclock and it’s rock solid, but it was a long wait to get there.)






  • I agree with the comments on this forum (https://www.thehighroad.org/index.php?threads/mushrooming-22-lr-case-heritage-rough-rider.891807/) that the cylinder could have a machining defect. (Basically a headspace issue, also but kinda not. The cartridges are sitting too deep in the cylinder itself.)

    If there is room for the brass to get pushed back far enough for it to mushroom out, something is seriously wrong. The issue could manifest from a machining error as small as 5-10 thou, I am speculating.

    My first thought was excessive chamber pressure, but the bulging would be much worse around and behind the rim itself if that were the case.

    The bullet and the brass get pushed in opposite directions and if the brass can move, it will move before it deforms. If it deforms, it’ll deform at the weakest spot first, like we see in your pic. (Excessive chamber pressure tends to expand the brass and lock it in place. With center-fire, it’ll blow the primers out or have a hole punched in them from the firing pin first. With rim fire, the pressure pushes back on the rim.)

    Also, check for excessive slop with the cylinder. If it can move forwards and backwards too much, that could also telling of issues with other parts of the gun. (Like I mentioned before, it doesn’t take much for a gun to be out of spec enough to cause issues with brass.)

    I am 46 and was in the ICU a couple months ago with super high blood pressure and a false alarm for a stroke. Up until last week, I hadn’t ran for proper exercise in 20 years:

    I can push myself to two miles, but it hurts. It only took a couple of months to work up to this point, so that was cool.

    But still, if he wants to show off that he is doing just a little better than a 46 year old with cardiovascular issues he can go right ahead. I ain’t going to yuck anyone else’s yum, but a comparison needed to be made.

    Edit: Fitbit doesn’t separate workout types that well without planning ahead and configuring a workout routine. “Lap 2” was a running mile, and the rest of the laps are walking.






  • I wanted to help clarify that many fungi do actually produce anti-fungal compounds. It doesn’t make sense at first, but mycelium can be insanely competitive and it’s usually “at war” with other types of fungi where growing conditions are ideal.

    Edible mushroom growers may have to deal with trichoderma infections from time to time. That little bastard fights mainly by mass multiplication and rapid growth. It’ll choke out and dominate other strains before they have a chance to produce any effective defense.

    When starting a mushroom grow, it’s basically just tilting the initial mycelium battles in the favor of the strain you want so it has a chance to dominate and kill other strains of fungi.

    It’s not a far stretch to assume that fungi developed odd chemical compounds if it even slightly increased survival odds. Any psychedelic aspects could be just an unintentional side effect that helped promote cultivation.

    Mixed theories on that, and most are older.

    On earlier computers, I had several ICs walk themselves out of sockets due to repeated thermal expansion cycles. Keeping the computer turned on eliminates most of that.

    Mechanical wear was another problem. Booting a computer was extremely taxing on old HDDs and floppy drives.

    Edit: Mechanical stuff also takes much more power to spin up and get running. The energy savings might be measurable if you just kept a computer running and didn’t power cycle it everyday.

    Most power supplies are really well designed now but they had a tendency to spike power briefly in when turned on. This was especially bad for older capacitors but also not healthy for the ICs. This still happens to a degree, but it’s not an issue.

    Now that boot times are reasonably fast and most everything is solid state and power managed really well, turning a computer off is fine.

    However, I just assume most electronics now just go into some type of deep sleep mode unless fully disconnected from any power source. That likely isn’t true in many cases, but I consider it healthy level of paranoia.
