I found it on my new AMD APU (E2-1800) based notebook. What services it provides, any reason I should keep it ON? Since notebook have an APU I can't even tell is this service corresponds to integrated GPU or some other AMD chip.
As it turned out, it's responsible for the additional
Here's that you get without it:
and with it enabled:
It has to do with Catalyst Control Centre. Here some info.
So keeping it on is up to you. There haven't been problems reported by disabling it.
My experience stopping FUEL:
so I'd just leave it running ;)
Without it, even if Cool 'n Quiet is enabled in BIOS, your power management settings will not include an item to set a minimum CPU speed. You will always be running at full throttle and full heat! Even AMD Overdrive will not be able to make the clock run slower than the max.
Note that this service will kill the "turbo boost" feature, which allows your CPU to overclock to a BIOS-selected speed automatically when it's executing only one thread. But I have a 9590 with 4.7 GHz nominal and 5.0 GHz turbo and it runs hot as a M.F.
I would much rather have that chip run cool at 20% speed nearly all the time and jump to 4.7 when needed, rather than run at 4.7 all the time at 60ºC, even though it would jump to 5.0 GHz when needed.
MORE ABOUT THAT EXTREMELY HOT PROCESSOR:
I even got a kilowatt power supply and added a 420-watt Peltier TEC (which is an interesting story all by itself). But the thermal bottleneck seems to be in the chip/waterblock interface. It's just not possible to push any more heat through a 40 mm² of copper without the hot side getting too hot.
I got a 50x100 mm plate so I can split the hose and add a second waterblock, but I still have to buy the waterblock and fittings. What's holding me back (besides the cost) is that I'd have to make a custom bracket to hold the whole thing down against the CPU. I just haven't gotten around to drilling holes in aluminum with my Dremmer yet, even though I got the diamond-studded aluminum-cutting bit for that purpose.
Instead, I disabled 4 of my 8 cores. If you have a 9590, DO IT. Now I can run the other 4 at full-throttle.
