I recently built my first pc and while overall the experience has been great i still have a few concerns as to the boost behavior of my r7 3700x.
So like some other amd users i've had some issues with the stock wraith prism cooler randomly ramping up to near full speed on stock settings, while the cpu is idle and sitting below 55°C. Naturally i thought my fan curve must've been to aggressive but after poking around in the bios that doesn't seem to be the case because the problem persists even when all fans are on the silent preset.
I did notice though that even when idle the cpu was constantly boosting up to 4.3ghz and would never actually reach the base clock of 3.6ghz. So I eventually stumbled across a youtube video (which ill link here) that recommended bringing the minimum power limit down to 50% from the default of 100% and limiting the processors maximum power limit (in the AMD power plan settings of the control panel) to anywhere below 100% because that specific number seemed to be causing the fan issue.
So i tried this and it seemed to work, the fans were much quieter and staying at a consistent speed but the cpu was now clocked all the way down at 3.5ghz and now even running cinebench r20 could not get the cpu to boost at all while the processor was well within its thermal limit.
So it seems like i have two options, use the lower power limit get better thermals, less noise, but less performance across the board. Or use the higher limit, worse thermals, more noise, but getting the performance i actually paid for.
So i really hope the chip wasn't actually designed like this and if anyone has any solutions id be glad to hear them. I'll link screen shots of the weird clock speeds here.
