Hi everyone,

Quick note: English is not my native language, so I used an AI assistant to help me draft this post to make sure my ideas are clear. Apologies if any phrasing sounds a bit robotic!

I'm reaching out because I'm stuck in a productivity and learning dilemma. I'm feeling a bit frustrated about where to direct my efforts since my free time is currently very limited, I'm a bit old to start at 43, but it is what it is.

My current workflow: I run a personal brand where I got used to CapCut's speed. I usually shoot on an iPhone 16 pro or an Osmo Action 6 (in D-Log), drop it onto my laptop, and have a video edited and published in 10 minutes. I'm doing well with scriptwriting and audio (I use Rode Wireless Pro mics), but CapCut is heavily limiting me now when it comes to advanced color grading and complex local effects, or integrating with ai generated b-rolls. I am a lawyer and mechanical engineer, on top of that, the overwhelming part is: I recently started film school online, so I absolutely need to make the jump to an industry-standard software. I'm also planning to add a DJI Mini drone soon to incorporate more D-Log footage.

The real bottleneck: My main constraint is TIME and the learning curve. I can't afford to learn three different programs at once. Budgeting for software licenses is fortunately not an issue right now, but my study hours are very limited, and I want to pick just one ecosystem to master 100%.

Available Hardware (For workflow viability context): Because of gaming and because I run local AI inference tools to automate tasks for my day job, I have a powerful hardware setup that I'd love to fully utilize, both at my desk and on the go:

• Desktop PC: Ryzen 9 9950X3D, RTX 5090 (32GB VRAM), 128 GB DDR5 RAM 6000mhz. For storage, I have a 2TB Gen 4 NVMe with DRAM and a 4TB Gen 4 NVMe without DRAM.
• Laptop (Where I prefer to edit due to convenience and the Apple/iPhone ecosystem): MacBook Pro with an M5 Pro chip and 48GB of unified memory with base 1 TB.

I know that performance-wise no software will lag on these specs, but my question is more about day-to-day workflow efficiency versus the technical depth required for film school. My options are:

1. DaVinci Resolve Studio: I've tried the free version. I know it's the undisputed king for film and color grading, but its node-based system intimidates me a bit, and I worry about losing the agility needed for fast-paced social media content.
2. Final Cut Pro: Since I prefer editing on Mac for social media, I know its optimization with iPhone clips is flawless and the magnetic timeline is fast. However, I’m afraid it might fall short for film school assignments, or that professors might push back for not using an industry standard.
3. Adobe Premiere Pro: I have zero experience with it. I know it's everywhere, but I'm worried it might require too many tedious steps for simple tasks that I used to solve in seconds with CapCut.

Looking for a realistic balance between the speed required for social media and the professional depth I need for film school: Which of these three would you recommend I invest my time in, and why? I truly appreciate your experience and advice so I don't waste my few available hours. Thanks a lot!

Hello, I’m currently migrating a workstation from a standard full tower setup, Corsair Frame 4000D, into a much more compact and portable Jonsbo D32 Pro chassis, and during the migration process I encountered a very strange compatibility issue between a Zotac RTX 5090 Solid OC and an MSI B850M Mortar motherboard.

The goal of the project is to build a transportable AI/workstation system capable of handling:

• local AI inference,
• CUDA workloads,
• video generation,
• and high-end productivity tasks,

while remaining compact enough to move between locations.

Because of the migration to a smaller chassis, I’m also changing cooling solutions and motherboard layout, which is how I discovered this issue.

Hardware involved

• GPU: Zotac RTX 5090 Solid OC
• Motherboard: MSI MAG B850M Mortar WiFi
• CPU: Ryzen 7 8700G or 9950X3d
• PSU: Msi Mag 1250gl unit
• OS: Windows
• GPU works correctly on another MSI X870 motherboard, so hardware issues related to the GPU can be discarded.

Main symptoms

The GPU is mostly functional on the B850M Mortar:

• System boots normally
• GPU outputs video correctly
• Windows detects the card correctly
• Drivers install normally
• GPU can run workloads/games/benchmarks

BUT:

• GPU fans stay permanently at 0 RPM
• Fans do not ramp under load
• Temperatures rise abnormally because cooling never activates
• Manual fan control from Zotac FireStorm also fails
• Even setting fans manually to high percentages sometimes produces no response

This behavior does NOT occur on the MSI X870 board.

Important observations

The exact same RTX 5090 works correctly on another system:

• fans respond normally,
• thermal behavior is normal,
• manual fan control works,
• no instability.

Tests already performed

Software / driver side

• Clean NVIDIA driver reinstall
• FireStorm reinstall
• Fan curves modified manually
• Different performance modes tested
• Zero RPM settings checked
• Drivers on GPU and Motherboard are updated.

Hardware side

• Reseated GPU multiple times
• Verified power connectors
• Checked PSU capacity
• Tested GPU on another motherboard (works correctly there)

BIOS / platform side

• BIOS defaults tested
• EXPO/XMP variations tested
• Possible PCIe negotiation issue considered
• Possible SMBus / telemetry issue considered

Current hypotheses

At this point I suspect one of these:

1. MSI B850M Mortar BIOS incompatibility with RTX 5090 cards
2. VBIOS compatibility issue specific to Zotac 5090
3. PCIe resource / telemetry issue on B850 platform
4. Interaction with Ryzen 8700G PCIe lane topology
5. Fan controller telemetry failing only on this motherboard

Further tests planned for tomorrow

I still have additional tests pending before concluding this is a hard compatibility issue.

Planned BIOS tests

• Force PCIe slot to Gen4 manually instead of Auto
• Test different PCIe link negotiation settings
• Continue testing BIOS defaults vs tuned settings

Planned hardware changes

I’m currently using a large air cooler that physically prevents me from installing both:

• the RTX 5090,
• and the Ryzen 9 9950X3D at the same time on this motherboard due to clearance issues.

Tomorrow I’ll install an AIO cooler so I can properly test the system with the 9950X3D instead of the 8700G.

Important reason for this test

Right now the system is running with a Ryzen 7 8700G, which only provides an x8 PCIe connection for the GPU.

Because of that, one of my current hypotheses is that the issue could somehow be related to:

• PCIe lane negotiation,
• bandwidth configuration,
• or platform behavior specific to the 8700G APU.

The 9950X3D should allow proper full-lane PCIe operation, so testing with that CPU may help determine whether the issue is related to the current x8 PCIe configuration.

Questions

• Has anyone seen RTX 5090 fan control failures specifically on B850 boards?
• Has anyone tested Zotac 5090 Solid OC on B850M Mortar successfully?
• Could this be related to the 8700G using PCIe x8 lane behavior?
• Any known BIOS versions fixing 5090 compatibility?
• Any known SMBus/fan telemetry conflicts on AM5?

Any ideas are appreciated because this one is extremely unusual.
