Scaling is buggy as hell with this processor.
It actually supports 384-1725Mhz.
Can't be used because the cores hang (no rampup from 384 to full speed possible).
That's why many use 800Mhz as the minimum frequency.
Then there are as already said reliable ping spikes and mass retransmissions when the CPU switches between different frequencies.
And as you can see from my screenshot, the R7800 doesn't have any temperature problems anyway (especially when mounted on a wall which ensures good air circulation).
I also have one hanging on the ceiling, it's a bit warmer
but everyone as he likes, I let my continue to run at full speed (as already the last 2 years)
I would say that a vertical installation is more effective than opening the router and replacing the heat conducting pads.
A vertical mounting makes easily -10°C difference
at least with the r7800, because it has nice vents on the front and back side
My R7800 is flat mounted on a desk but I've added 3 spikes (from an audiophile speaker) that are adding some space under it to have a good air circulation (and it looks nice also ), with 19 degree inside and fixed speed at 1725MHz, right now the router temps are
So what is the utility of use the scaling option? Surely it adds few (less than ms) delay, but multiply it for millions of packets/request daily...

Yes thanks I know what I wrote, I was simply asking what is the cause to turn back to "on demand" cpu scaling. What is the benefits, considering that with some spacers under the router it stays quite cold.
I ran this on 2x ea8500, 2x r7500v2, and an xr500 last night, just because I was curious. All chips were <60* beforehand. After running the script, I confirmed they are all scaling properly. 12hrs later and under heavier usage, all temps are within a degree of where they were last night. I couldn't replicate the mention of ping spikes either.
As ho1Aetoo mentioned with his r7800, the biggest temp difference with the xr500 comes with placing it vertically. The heatsink is a large metal plate covering the entire board. With the vents at the top & bottom, convection allows it to more efficiently cool. Warmer air rises out the top & draws in cooler air from the bottom.
