    iMac Pro X299 - Live the Future now with macOS 10.14 Mojave [Successful Build/Extended Guide]

    Superb work @kgp. Can you elaborate on section E.9 H regarding CPU cores? I'm not sure what this does and how I create the right patch for i9-7900X processor. thanks!

    How to build your own iMac Pro [Successful Build/Extended Guide]

    That's part of it, but I've run single thread benchmark in Windows and only one core goes to max clock. All others idle. They should all be running the same speed if you set to enhanced multicore performance and disable energy savings. Additionally, the single core does not clock to the Turbo...

    How to Create a macOS High Sierra Public Beta Installation USB

    I didn't think about terminal so that may work. However, as noted, if the drive has a prior Apple formatted partition, yes Drive Manger works fine. However a brand new drive does not show up and Windows formatted drive and partition show up, but can't delete partitions or mount. Perhaps terminal...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    The option is there in the F7I BIOS for Gaming 7, but it does not work as I tried in Windows. Other things related to CPU overclocking that don't work on this BIOS version (all confirmed in Windows 10): Mesh multiplier - once you overclock this, it sticks to the new frequency 100% and does not...

    How to Create a macOS High Sierra Public Beta Installation USB

    Please add this warning to the general instructions: I have confirmed on my MacBook Pro and my Hack. The drive that you want to install PB5 must be pre-formatted to Apple format. If you try to use an unformatted disk, it will not show as an available disk. If you try to use a recycled disk with...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    Gigabyte should also be able to lock the cores. I had that enabled on my previous X99 Gigabyte system. You are correct in that the BIOS setting is there but it doesn't work because I can't even get it to work in Windows. I'm sure Gigabyte will correct it in another BIOS release. The voltage...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    Thanks for sharing! A couple notes after I finally got installation to work on my i9-7900x and Gigabyte Aorus Gaming 7 and using PB5: I had to use a blank drive that was already formatted to Mac extended journal. My fresh out of box SSD did not even show up in Disk Manager. Once formatted...

    Jumping to Skylake-X + X299 mobo

    As far as I know, the only practical way of safely testing overclocking and verifying stability is to do it Windows since there are Windows tools for this and practically none on Mac side. I kept my OC BIOS setting simple: CPU multiplier - 46 Core voltage - 1.175 and also set Adaptive voltage...

    Jumping to Skylake-X + X299 mobo

    Hmmm. I never got power management to work on x99, but it did support a few speed step frequencies and would drop to 1800 MHz at idle for about 12 watts if I remember right. Hopefully final release High Sierra will work better for x299 and also support Turbo Boost 3.0 since all of their new Mac...

    Jumping to Skylake-X + X299 mobo

    Overclocking update: I increased stock Vcore from 1.08 to 1.1V and have a stable 4.5 GHz overclock. 4.6 was a no go and will need more voltage but I will stop at 4.5 since stress testing puts temps in the mid 80 C which is a safe 10 C from throttling temp. I plan to run stress test longer to...

    Jumping to Skylake-X + X299 mobo

    Excellent motherboard imho. It's the cheapest one out that has dual 8 pin CPU power connectors. 9 gives you an upgraded DAC and a 2 more snazzy m.2 heat shields plus a base plate under the PCB. Installation was easy and everything worked on first boot. The BIOS seems mature enough but the...

    Jumping to Skylake-X + X299 mobo

    Here's a little taste - stock voltage and 4.3 GHz Turbo Boost. I haven't even started overclocking yet and think this can hit 4.5 Ghz easy. Just need to deal with the heat.

    Jumping to Skylake-X + X299 mobo

    Already ahead of you! Got a new i9-7900x with Gigabyte Aorus Gaming 7 x299 board running Windows 10 (2x8 CPU power connectors so no problems overclocking). My x99 system died on me and as luck would have it was a dead CPU. I was going to just replace my CPU, but realized how much I would be...

    Apple Reveals macOS High Sierra at WWDC - Available Fall 2017

    Just speculating that the new iMac pro will be x299 with i9 2066 pin processors. Since the top end config is 18 core, that is where the i9 tops out. I think Xeons go up to 24. If true, this is a good read on what upgrading your current system may look like...

    NVIDIA 'Pascal' Graphics Drivers Released: Buyer's Guide Updated!

    Titan Xp works and installs just fine. All I had to do was install the card and done. I don't use HW Monitor so I didn't have to remove it. This should last for quite a while.

    10.12.4 x99 Broadwell-E Compatibility?

    Hi All, Thanks to all the dedicated folks in the community that make it possible to run x99 platforms on Sierra. I've had a stable running system with the i7-5820K for the last 2 years. I have also followed the Hackintosh mantra of "if it's not broke don't fix it". I am considering upgrading to...

    iTunes Protected Video Black Screen Solution (HDCP)

    Installed lilu and shiki latest builds and reset DRM on my X99 system on 10.12.4 and it works for downloaded videos but not for streaming. I believe devs said that shiki for streaming would not be possible for the foreseeable future.

    NVIDIA 'Pascal' Graphics Drivers Released: Buyer's Guide Updated!

    Hi All, I do want to upgrade to a 4K monitor, but not sure if the resolution is working without issue. I use Mac Pro 6,1 definition and will pair that with a 1080 Ti or Titan Xp. Are there any special kexts or concerns about 4K resolution?
