8350 still randomly throttling
8350 still randomly throttling
I have read all sorts of posts and implemented suggestions, but sometimes 6 of the 8 cores drop from 4019 to 1407 ... which means I can't use the system to record audio. Most times if I reboot, the problem goes away. AMD-OD and OCC report stability, and when running at 100% the clocks don't drop speed. They seem to happen under low load, not high load; but when it happens I have to try reboot. PITA!!
I'm running Win7x64 on Gigabyte 970A-UD3P. Reportedly, there was a 'hotfix' for Win7 and throttling, but could not locate it (pulled by Microsoft?). I did search the registry for the questionable string and set those to supposedly solve this issue. And, NO, I can't upgrade to Win10 because of all the hardware I'd have to replace. $$$$$$$$. I'm a songwriter, and this is my tool.
I was concerned about the temp of the NB (or at least the heatsink with the Gigabyte signage), and put a 40mm fan blowing right on it. This dropped the NB temp from 60+ to 40+. My CPU no load temp is 26 and at 100% load will slowly creep up to 57, no higher.
The clock, NB freq, HT link and clock ration are all set at Auto. Core Perf Boost, CPU unlock, cool and quiet, C1E, SVM, Core6, and APM are Disabled. HPC mode is Enabled because I run Sonar which is heavily multithreaded.
Are you certain the 6 cores aren't being utilized? Is the application limited to single-threaded operations or can it leverage two cores? This is due to the fact that the FX-8350's cores operate at 1407 MHz when idle. Does this behavior repeat during CPU stress tests such as P95 or Intel Burn? Additionally, is the Win Power Option configured for High Performance?
No, Sonar DAW makes full use of all 8 cores when they are at full capacity. When only 6 cores are active at 1407, it doesn't run smoothly (experiences pops and clicks). Sonar was designed as a balanced, multithreaded application. I never faced issues running an AMD 6300 with 6 cores at 3.8ghz for years on the same machine.
During stress tests with P95, OCC, and AMD-OD, all 8 cores reach 4ghz. This happens while I browse the internet, watch videos, or do light browsing. It continues without stopping unless I restart the system, which sometimes requires a cold reboot. In short, heavy CPU usage doesn't automatically wake up idle cores; it needs a full reboot.
