HDX PT 2018 CPU Spikes AAE -9171 Halts Playback

[Howardk]

I tried testing in various video modes. . . such as DVI only on 20" monitor, DP only on 34", HDMI on 34", HDMI on 34" at half resolution. I did not perceive any difference and simple test session halted within a few minutes of running with 128 buffer.

I uninstalled the Avid Application Manager, and it seems to have made a slight difference. . . so far the test has run 54 minutes, but my system's performance and CPU spikes/Pro Tools Halts, have been inconsistent (like the weather), so hard to know just yet. I will run a bunch of tests. . . The center loading of the cores is still happening, and the CPU Total, is still jumping around a lot, which does not happen in my Pro Tools 10 (Mountain Lion) with HDX.

Howard, I am now test running a PCIe M.2 SSD blade running 10.12.6 Sierra and have just reinstalled PT Ultimate 2018.12 with all my plugs and had zero, I repeat zero problems today.

I hope it keeps working well for you!

Which PCIe card for the SSD blade?

[the.engineer]

Wolftech Pulsecard - PCIe 3.0 x4 adapter. The blade I'm running is the 256GB Samsing SM951 AHCI.

Howard,
Is there anything else we've missed here with your setup? I'm sure there's something simple that's a quick fix. If it works here with my computer with the same setup there's got to be a way to get yours working.

Best,
James

I hope you are right. . . I have been having simple recording sessions with clients and getting by, but still getting the AAE 9171 even with a 512 buffer from time to time, and only running a couple AAX.Native Plugins.

The centre loading of the cores that I am seeing on my system seems to be what puts it over the top. I have been trying different test sessions, and I am finding that same issue. Plus the results are inconsistent. Sometimes it will have in 2/3/5 or 10 minutes before a Halt, and then sometimes it will go the full 2 hour test a couple times in a row without a halt. I have had tests successful with a 64 buffer for the full two hours, and had 512 halt. . . I can't see a causation or any pattern.

I would love to be able to try my test session on other computers, to see how they do and how the CPU core loading looks.

I am going to do a fresh install on a different SSD drive one more time.

Send your test session over (PM me) and tell me the parameters

That would be great. . . I will PM in a bit. Thanks!

Ok, this may be promising. . . I was reading another thread it was suggested to someone else they just try running without the Pro Tools edit window displayed. . . so I did and the Total CPU meter spikes greatly reduce as soon as I close that window and the spikes come back as soon as the Edit Window is opened again.

I had tried my system on a smaller monitor, as well as different connections (HDMI, DP, and DVI), but did not notice an appreciable difference in CPU spikes on the meter, but I did have the Edit Window open in all cases (as I did with my PT 10 testing with HDX card and PT 10 did not show CPU Spikes).

I will run some more test rounds with the Edit/Mix windows closed.

Hoping all I need is a better video card, which I was hoping to upgrade for performance and be ready for Mojave in the future. . . but nothing local I can try. . . is there a clear winner for graphics card upgrade (would like to retain option to select startup disk, not exceed power supply)?

This one will definitely work out the box

https://eshop.macsales.com/item/Sapphire/100352MAC2/

Can be tricky to come by though.

This one is in the UK https://www.ebay.co.uk/itm/Radeon-HD...28.m4335.l8656

But may also not have the right outputs for you.

I know you’ve already contacted macvidcards without success, but try again. My graphics card was flashed to show the grey boot screen by a guy in Poland who is a subsidiary of macvidcards.
