FX-8350 operating at 1.4GHz/0.89V
FX-8350 operating at 1.4GHz/0.89V
I have an MSI Gaming 970 and an FX-8350. (It’s time for a refresh.) For some reason, the CPU is now stuck at 1.4GHz (x7 multi) and 0.896V, which is way below its normal settings of 5GHz and 1.325V. It adjusts itself to these values no matter what I change on the motherboard—like turning off Cool N Quiet or manually setting frequency and voltage. The frequency stays fixed even when under load, so it’s not just about saving power or a single feature. It’s actually using the high-performance mode in Windows, and I updated the BIOS, but nothing helped. I’ve also tried activating OC Genie without success. The odd thing is that package/core temps are showing about 12°C lower than room temperature—even though I’m running it on a very low voltage under my Hyper 212, which makes it seem impossible. And the CPU VID reads the same incorrect setting in the BIOS. I don’t know what’s normal here, but I’m not sure how to fix this. If anyone has any tips or solutions, it would be a huge relief.
It appears the Maximum Processor State in your Windows power setting is configured under 100% utilization.
Your power supply unit is [PSU] and it's [age]. Your voltage differential is [VDD].
It's currently running at 100% Seasonic M12II 620W, roughly four years old. While not the top model by today's rules, it should hold up well for this use. The readings show 0.896 for both VDD and VID, even though the BIOS was manually set to 1.4.
CMOS cleared once more, now powered by a different PSU. Wifi and USB cards were removed—still nothing changed. Later update: extracted all but one RAM stick, and performance jumped to 2.1GHz (about ten times) at 1.016V under full load. Not sure if this is progress or just more confusion.
Hey everyone, I'm really confused. It seems I accidentally turned on Slow Mode, which sets the CPU to its lowest speed. This lets me safely start a system even with LN2 settings still active. Since I've never used LN2 before, I didn't expect it to work like that. A good lesson learned!
