Note the at least 3 literal errors on the pass screen…

Edit: Votes don’t matter to me, but if you missed the three obvious errors on screen, you shouldn’t be a technician. The problem was failed integrated GPU capacitors.

    Just an observation from someone who happened to memorize some ASCII code: from an ASCII viewpoint, 45 73 63 is hex code for “Esc”, with “s” being 73 and “c” being 63. I can readily see where bits flipped: at the fifth least-significant bit (compare 73 (0111 0011) and 63 (0110 0011).
    Similarly, “no0errors” where “0” should be a space. “0” is 30 while space is 20. Again, another specific flipping at the fifth least-significant bit, only difference that this time a 0 became 1 (compare 30 (0011 0000) and 20 (0010 0000)).

    The delimiter from the status of “Test #0” seems like a control char-code emerged from a start bracket. If the start bracket has the same char-code as expected from ASCII (5b), and considering how the flipping of the fifth least-significant bit seems to be recurrent, it’d be 4b but this would result in uppercase K, so it’s either a different char-code for bracket or a bit-flipping happening in another position.

    But what renders text is the graphics card. Given that the background is slightly shifted rightwards (notice how the blue background cuts through the initial letters from the first column of text, particularly “A” from “Athlon”, “L” from “L# cache” and so on), this seems a graphics glitch rather than a memory glitch. And memtest86+ isn’t designed to test the GPU, so it’s beyond the heuristics. It’s akin to expecting memtest86+ to test for dead pixels on a LCD panel: it simply can’t.

    (P.S.: it’s unnecessary and disrespectful to attack others just because others couldn’t see what you wanted them to see; slurs won’t help people see what you see)

      Thank you for the breakdown, that’s effectively what happened.

      Sorry if I came off the wrong way for many, I’ll just more or less drop this post/comment chain.

    I believe, and I’m probably wrong here, so feel free to correct me, that the visual glitches are part of the video card’s implementation of this specific screen mode, which would be a graphics memory glitch. So the RAM might actually be fine, but you may have a bad video chipset instead.

      You’re both right and wrong. All cool.

      The system’s RAM was okay, but the system’s VRAM was separate, but still integrated. It was the VRAM caps that were bad. After replacing those, the system worked fine.

        Oh, nice! I was on the right track. :) Also, I think there’s another glitch. Shouldn’t there be a progress bar next to the 10%?

    for a moment I thought this was 86+, for which you could submit a lil pr to fix this typo. is this is the passmark one you can prob send them an email or something?

      Wait, you said typo?

      God fucking damn, none of you new fuckers can spot a binary glitch in ASCII?

      There’s literally 3 on screen!

          Figure it out then, there’s literally at least 3 errors on screen.

          If you’re offended by my words, then prove me wrong.

          This is OG photo from like 2011, from hardware made around 2009.

          This is the only remaining photo I have, captured at work on a PlayStation Portable.

          Yes I had the Chotto Shot Camera accessory.

            you posted this in a tech support community, it doesn’t sound as if you need support. I’m not sure what you really wanted here?

            the interesting this is that you attributed this anomaly to gfx hardware, in an environment which isn’t composed by gfx hardware.

              Honestly, I just wanted to test the tech support community.

              I have learned that people couldn’t answer the enigma of why a RAM test would both pass and fail at the same time.

              Answer was bad caps, which I replaced, and worked fine.

              The real question is if people/techs could even notice the errors on screen?..

              This was a test.

                except that this blatantly isn’t a test, and that wasn’t the answer? baby what is you doing?

                  This was a test, based on proven evidence and full repair, if anyone in tech support would even think to look at or test the capacitors.

                  At this point, more have failed than passed my test.

                  NEVER IGNORE THE CAPACITORS!

      It was a very old version from around 2008, and what I discovered was that the onboard GPU had failing capacitors. And yes, screenshot from real hardware.

      I actually managed to fix it, but like who the hell expects the literal MemTest to declare a pass when obviously something failed?..

      Edit: Assumption, MemTest wasn’t designed to test GPU memory back then…

        oh right, I’m not sure if the GPU would really compose that differently even though it was faulty? honestly my guess was this was a typo in the program itself?

          Again, please re-read my comments.

          I didn’t say the GPU was faulty, I said the GPU capacitors were faulty.

          Please learn the difference between components.

          Please.

              I replaced the obviously exploded capacitors, and the system worked fine.

              Explanation is simple, diagnostic software ain’t smart enough to identify that capacitor C307 or whatever is expanding and about to explode, but putting your own human eyes on it can reveal a lot!!
