Hey everyone,
I’ve just rebuilt my DAW around a new AMD Ryzen 7 5700G (using its iGPU for a fifth display) and a Mackie Onyx 1•2 interface—swapping out a Ryzen 5 3600 —and I’m running into persistent crackles, pops, and clipping in Cubase 12 even at 2 048-sample buffers.
My system:
- CPU: Ryzen 7 5700G (Vega 8 iGPU driving 5th monitor)
- Mobo: Gigabyte B450 Gaming X (BIOS F67G, XMP on)
- RAM: 64 GB DDR4-3200 (4×16 GB)
- GPU: ZOTAC GTX 1070 Ti (Studio driver, clean-installed)
- Audio interface: Mackie Onyx 1•2 on rear USB 3.0 hub (latest ASIO driver)
- Storage:
- OS + pagefile → Lexar NM620 2 TB NVMe (fixed 64 GB pagefile)
- Cubase projects → Crucial MX500 & Intenso SATA SSDs
- Two HDDs (media/archive)
Cubase setup:
Version 12 Pro, projects at 48 kHz/24-bit
ASIO4ALL → switched to Mackie Onyx ASIO (still clips under load)
Buffer tested 512 → 2 048 samples (same result)
“Release driver in background” disabled
What I’ve tried so far:
GPU DPC spikes (nvlddmkm.sys ~2 ms):
Clean Studio-driver install + DDU, disabled NVIDIA HD Audio, set “Prefer maximum performance” → GPU spikes eliminated
Storage DPC/page-faults (CLASSPNP.SYS ~1.2 ms + 20 000+ hard page-faults):
Moved pagefile off SATA → fixed 64 GB on NVMe, removed on all other disks
Disabled SysMain, turned off SSD optimization, excluded audio folders from AV & indexing
Reinstalled AMD chipset drivers, updated SSD firmware
Power & BIOS: High-Performance plan, PCIe Link State PM off, USB power-saving off, PBO on Auto, C-States default
Current results:
LatencyMon (idle) shows no major DPC or page-fault issues
Cubase still produces underruns under moderate project loads (50 audio tracks + Kontakt libraries)
- Has anyone tamed a 5700G + discrete NVIDIA card for glitch-free audio?
- Are there any further BIOS tweaks (C-States, PBO, Precision Boost settings) or Windows registry hacks you’ve found helpful?
- Would a different, ultra-simple USB interface (e.g. Behringer U-Phoria, Focusrite Solo) sidestep whatever is blocking the Onyx?
