I updated my profile a bit but it was mostly correct, I'm on a desktop with HD3000 graphics from a i5-2500k, plus TL-WDN4800 and GTX580. Previously also had a USB3 card attached, but removed it and it didn't help with the reallocation error.

Ah, that's a shame - it doesn't seem to work on my board (reallocation error - same as this user). I've read that it can fail when having >2 PCI-E devices attached, which I do.

Oh, I see. I set the memory to preallocation to 64M and DVMT to 'Max' but that made the artifacting much worse - moving grey squares and lines all over the screen. With DVMT Prealloc=512M and Max DVMT='Max' I normally I only get thin white lines here and there.

Hrm I just rebooted and my BIOS only offers 128M, 256M and 'MAX' as the available options for DVMT. I used 128M and we'll see if it's better.

Under IODeviceTree/PCI0@0/GFX0@2 I do see APPL,snb-platform-id with value <10 00 03 00>.

I have slide=0 set that helped tremendously to reduce (but didn't eliminate entirely) the artifacting. I'll see if a new revision of Clover (UEFI) addressed my boot issues. Thanks, I'll set that. Devices/AddProperties in my Clover config.plist: <key>AddProperties</key> <array> <dict>...

Oh, so we do have a different device ID... 8086:0112 for me. No patched ACPI - since updating to Gigabyte's uEFI beta BIOS on GA-Z68-D3H-B3, things have worked out of the box (aside from the artifacting). I'm using Clover (legacy) as my bootloader, as Clover UEFI sometimes fails to load the...

I don't want to hijack this thread, so could you please PM me the configuration you have for your BIOS (i.e. memory size, UEFI or legacy Clover), boot parameters and any kext changes if applicable? I have the same device ID as you (dev 0112, vendor 8086) but it's always giving me issues... I...

For what it's worth, this may be related to 10.11.4. My desktop (i5-2500k) HD3000 has been working fine up until I installed 10.11.4, and nothing I tried would get rid of the artifacts. I restored my 10.11.3 kexts and things are working normally again.

Same issue here on a Z68A-D3H-B3 after using MultiBeast. I suspect it has to do with kernel caches, as booting with the '-v' flag (just type that in when you're selecting your installation in the bootloader) works fine.

Likely your OS X installer is damaged and you should re-download it.

Are you using Chrome to play music with USB audio output by any chance? If so, there's a known bug in Chrome about this. Selecting a different audio output from System Preferences and then choosing your normal output again will work around the problem until it gets fixed upstream in Chrome.

I'm seeing the same symptoms too on slightly different hardware specs: i5-2500k (not overclocked) GA-Z68-D3H-B3 8GB DDR3 1600MHz GTX 580 Just happened to me twice in two days, but the machine often goes for 2-3 weeks at a time with no freezes.

How are you testing for full acceleration? As well, be sure that you ran the cache regeneration steps... I've found that you can get some bizarre results if you don't.

If the resolution issue above is not applicable, try setting your internal GPU as the primary/init first in BIOS and then connect your two displays to the GTX580. You won't get any display output until OS X initializes, but it should work well. When doing upgrades or testing, just connect a...
