R7 5800X3D on an B450M-HDV R4.0
Posted by eggwarders@reddit | buildapc | View on Reddit | 7 comments
Since AMD is officially bringing back the Ryzen 7 5800X3D, I've been considering it as an upgrade from my Ryzen 5 5500. Lately, I've been running into CPU bottlenecks in quite a few games, especially after upgrading my GPU, and I'm getting tired of leaving performance on the table.
My current motherboard is an ASRock B450M-HDV R4.0. I'm fully aware it's a very budget-oriented board with fairly weak VRMs and not much in the way of VRM cooling.
For those who have experience running X3D chips on lower-end B450 boards: would you keep the board and run the 5800X3D with an undervolt/Curve Optimizer, or would you recommend upgrading to a better AM4 motherboard with decent VRM cooling?
The rest of the system is:
- RX 9060 XT 16GB (although I'm planning on getting the 9070 XT)
- 32GB DDR4-3200 CL16
- 1440p 180Hz monitor
I'm trying to figure out whether it's worth investing in a better AM4 board or if my current one can handle a 5800X3D without issues.

Mine is the 5700X3D, but it runs as cool as, and reports lower power usage under load (not idle, of course) than my old 5700G. You should be fine.

Try the same board, worst case get a B550 with nice cooling. 80$ from sapphire very new kinda cheap.

Will do

The x3d chips do not get that hot at all under regular gaming loads. People were installing them on cheaper, older AM4 MOBOs. As long as you have good airflow and a good cooler you’ll be fine

Investing in a new AM4 motherboard is also probably not worth it, so yeah, I'll probably stick with my current. I appreciate the reply.

I'm not sure the VRM is that big of a deal for the 5800X3D. That chip has the X3D cache on top of the CPU, and that prevents the CPU from being overclocked, or even hitting the advertised clocks that often. You undervolt it and set the curve optimization to get it to boost to the advertised numbers for longer. But it doesn't draw a ton of power like the chips without the X3D cache. The regular chips could be overclocked well, but still had to go back to main memory often and were limited by the cache misses. The cache itself didn't consume a ton of power.

I didn't know about that. Thanks : )
