AMD Radeon HUGE Stuttering

yeah, by GPU stays cool. But what are you guys talking about the +5 and +12? Is this something about the PSU? So what is the way to fix this problem. I know we can ahve hypothesis on the situation. But what is a way for an actual try at a fix?

It's doubtful the sensors are reading those voltages correctly, but if they are it means your PSU is extremely faulty. And you need a new PSU. But I really doubt those voltages are remotely accurate.
 
First things first - if you have anything overclocked set it back to defaults. Test again.

You likely want to get the following information:
- CPU clock speed over time
- CPU voltage over time
- CPU usage over time
- CPU temperature over time
- GPU clock speed over time
- GPU memory clock speed over time
- GPU voltage over time
- GPU usage over time
- GPU temperature over time

These will tell you if you are throttling and potentially due to what. At the moment it looks likely that the GPU or CPU is downclocking, that seems likely. Its also possible its not that but its the first thing you need to rule out.

It shows your 12V and 5V voltages as being off, especially the 12V. Either your PSU is having more current drawn than it can handle, resulting in voltage sag, the PSU is failing, or its a software bug in HW Monitor.

You can either try another piece of software, or use a multi-meter to actually measure the voltages while a game is running.
 
If the 12V rail is actually at ~8V, thats most likely your issue. Both the CPU and GPU are not going to be very happy with that kind of voltage sag.



It's a software issue. CPUID isn't reporting the 12v correctly. He'd have to get out a multimeter to actually check, CPUID not a lot of help here.
 
While it could be hardware, I'm inclined to suspect software. Brightcandle's suggestion makes sense as does downloading Processexplorer if you get CPU spikes and something like DPC latency checker.

Although if it is something (probably some driver) spiking the CPU it may be tricky to track down. Always handy to have a spare Windows install somewhere to rule out hardware. Unfortunately, Live Linux CDs are no good for running 3D games 🙁
 
so if it has to do with throttling for software, a clean install of windows, will rid it of its problem?
 
Looks to me like either your CPU is throttling, or you have a misbehaving program/virus slowing down your game.

This is the likeliest cause, when a PC runs fine, then out of the blue, you experience major intermittent slowdowns.

Do not rely on one anti-virus only, check once in awhile with an additional scanner.
