    A strange problem with Rx 580 Powercolor

    I have a Sapphire RX580 Nitro+ 8GB and have exactly the problem at boot up (as the RX480 video above). I am living with it as I do not boot often since the system sleeps and wakes very well. I have IGPU (i7-3770K) enabled in connector-less mode but the RX580 is primary (in UEFI). Disabling the IGPU does not make any difference to the boot-up flashing. I cannot remember what happened when the IGPU is enabled in connector mode with a screen connected to the IGPU and a second screen connected to the DGPU. May be, I'll try it if I get some time.

    Clover Themes

    .....use the attached terminal command (thx to a tip from blackosx). Give it the name of the theme you wish to download as a parameter. get-theme.sh

    On my Z77X-up5 with i7-3770K, I tested with 4 monitors without any issues and I tested all 5 ports. I have Saphire Nitro+ RX 580 8GB. It's 5 ports (2xDP, 2x HDMI, 1x DVI-D) are an almost perfect match for the Orinoco framebuffer and the generic AMDRadeonFrameBuffer.
  4. Really ? You cannot view/mount/unmount EFI partitions from within the high sierra DU like you could with the old one (with Debug enabled). Plus, the new DU has terrible user interface compared to the older one for changing partitions.

    Clover Themes

    Stop Stop...please stop...I can't take anymore...please...please...I got way too many favourite themes from you now..
  6. Thanks. This problem has been bugging me for a while a while with recent Clover builds on my Z77X-up5 motherboard. Just replaced the aptiofix3 driver with aptiomemoryfix and done 5 restarts without issues. So far so good. I think issues arise when there's a system change like installing or moving kexts. PS. I get the message 119/256 slide values. What does that mean ?

    Clover Themes

    Somehow my reply did not post here. Second attempt. Another great theme. I always liked the original from @blackosx that I used on all my builds during the Chameleon days. Finally, nice to see it in Clover. Great job. keep it up.
  8. Thanks. Good to know. The default should be to click the title. That xx hours ago text is so small and it's fading to grey colour.
  9. Thanks. That updated link worked. The problem was not just with your posts but others too. I'll report them here as I find them. BTW, another great clover theme from you.
  10. Welcome back. Can't say I am completely impressed but hope the look & navigation improves. I miss the the old "New Content". The new "Unread content" is not easy to navigate as it just lists unread posts with the link to the FIRST post and not the last past which means you have to click the ">>" to get to the last page. Inefficient. Also, more importantly many links to people's uploaded files do not work....well the few I tried. E.g. this one (Nightwish theme) just downloads an Zero byte file. I'm using macOS safari.
  11. What's Compute score from Geekbench 4 ?

    Intel CPU hardware vulnerability

    sorry but this total gibberish

    Intel CPU hardware vulnerability

    Apparently 10.13.2 already had the fix (lookup Double_map) in that last security update but a more rigorous fix is coming in 10.13.3. If you want to check the performance 10.13.2 then you have to compare it with 10.13.1 to see if there's a hit. Chances are you will not see a difference unless the synthetic benchmarks you choose to use make lots os system calls (into the kernel).

    Intel CPU hardware vulnerability

    The researchers who discovered the Two issues say: "Which systems are affected by Meltdown? Desktop, Laptop, and Cloud computers may be affected by Meltdown. More technically, every Intel processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013). We successfully tested Meltdown on Intel processor generations released as early as 2011. Currently, we have only verified Meltdown on Intel processors. At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown." The key point is that "it is unclear whether ARM and AMD processors are also affected by meltdown". That research was done by trustworthy third-party.

    Intel CPU hardware vulnerability

    Not just related to Intel but to AMD and ARM too (though AMD seems to be in denial). There are two issues: "Meltdown" and "Spectre". Meltdown is more related to Intel platforms and Spectre affects ALL architectures. Spectre is hardest to fix. More details here: https://meltdownattack.com Personally, I think it was irresponsible of the register to publish a fairly inaccurate story BEFORE the Intel, AMD, ARM, MSFT, GOOG, ETC had the fixes in place - like any responsible organisation. But then again, they've always been a rogue hack and true to their nature. I wonder if they sold their Intel shares before publishing and bought them back after publishing at 6% gain ?
