New 5950X model; significant temperature variation across CCDs
New 5950X model; significant temperature variation across CCDs
Did you clear the CMOS? Are the newest BIOS and chipset drivers installed? What are the clock speeds? It seems one CCD is behaving oddly, possibly due to a Windows issue—consider reinstalling Windows.
Clocks operate at 3.6MHz idle, increasing to 4.7MHz consistently, with occasional spikes above 5MHz (refer to the graph); a potential Windows issue exists, but I tested a 5950X on this machine for three years before it failed. I’ll verify if Linux shows similar temperatures before making any adjustments to Windows.
You might be onto something with the Windows issue. Although I’m not aware of a Linux monitoring tool as thorough as HWINFO, it appears the CPU stays around 41°C and reaches a peak of 71°C during Linux benchmarking—differences that are significant. If anyone knows about a Linux utility offering temperature breakdowns comparable to HWINFO, please share. I’d like to compare how the CCDs perform.
It's typical for a 16-core processor to run around 1.5V, though that's not standard. Check your BIOS settings for any ASUS boost profiles and reset them to default. If Windows acts odd after a restart, it could indicate a reinstall or replacement issue. The temperature difference between cores isn't unusual—91°C vs 71°C is within normal ranges. Which benchmark were you using to record the temperatures?
Didn't locate anything similar to HWMonitor for Linux, sorry... unsure if it will function under Wine or in a VM environment. Windows 11 has reported numerous issues with AMD chips—some outdated, some partially fixed, and others possibly due to an update glitch. A fresh installation might resolve the problems.
I also faced some difficulties. I might check HWINFO in Wine just out of interest. Right now I’m using Windows 10, and switching to Windows 11 seems like a reasonable move.
It's typical for temperatures to vary between Windows and Linux on the same machine. I've noticed this pattern before, especially when checking performance tools like Passmark. My older 5950X ran smoothly with similar idle/load temps in both environments—around 45 to 75 degrees. The differences usually become noticeable only after intense usage.
They need to stay within the same temperature range during low load/idling on a desktop (except for the 7950X3D which has its own cache that can raise temps). At medium load—like gaming—you’ll notice bigger differences since games use just a few cores. At high load, performance levels back out as all cores are engaged.
