Which Prime95 release should I use? 26.6 or 28.9? I generally recommend stress testing with version 26.6 and smaller FFTs.
28.10.1.0 I ran the small FFT tests. The program begins to drop after roughly two minutes.

I'm puzzled. The CPU usage is showing the load percentage. You should focus on clock speed and temperatures too. If your program indicates thermal throttling, pay attention to that as well.
I use a tool named "Open hardware monitor" which displays my clock speeds dropping from 3800 mhz to 1200-1400, yet the load percentage remains at 100% all the time. My temperature also doesn't exceed 56°C.
Could you tell me what CPU you have? What is your motherboard model and power supply type?

Which Prime95 release should I use? 26.6 or 28.9? I generally recommend stress testing with the older 26.6 and smaller FFTs.
28.10.1.0 I performed the small FFT tests. The program begins to lag after roughly two minutes.
After using version 26.6, newer releases demand the CPUs excessively and occasionally lead to excessive voltage readings. Consider reverting to 26.6 before concluding it's a hardware problem.

After using 26.6, newer versions push CPU limits too much and can cause voltage spikes. Consider reverting to 26.6 before assuming hardware failure.
I've experimented with four different programs now, and it seems the issue isn't mine. My readings stay between 1.26 and 1.27v.

I've tested four different programs now; I don't think this is the main issue. My voltages stay between 1.26 and 1.27v.
I checked your motherboard's product page – only three VRMs, none with cooling. If your CPU is receiving the voltage it claims, it's likely fluctuating.
Poor power delivery leads to poor results. You'll need a motherboard with better power systems if you want to keep using that CPU. Or, instead of spending more on your current machine, wait for benchmarks on the upcoming AMD Ryzen 3 or switch to Intel.
Weberdarren97 asked about Prime95 versions and recommended testing version 26.6 with small FFTs. They shared their test results, noting CPU stress levels increased after 26.6 and voltage fluctuations occurred. They mentioned trying four different programs without finding the issue and confirmed stable voltage readings. They also pointed out limited VRM cooling on the motherboard and suggested better power delivery or considering a switch to Intel.

I've experimented with four different programs now; it seems the issue isn't with them. My voltage readings stay between 1.26 and 1.27V consistently.
I checked your motherboard's product page—only three VRMs are listed, none of which include cooling. If your CPU is receiving the voltage it claims, fluctuations are likely the cause.
Poor power delivery results in a poor experience. You'll need a motherboard with better power systems if you want to keep using that CPU. Alternatively, instead of spending more on your current setup, wait for benchmarks on the upcoming AMD Ryzen 3 or consider switching to Intel.
I doubt adding fans or heatsinks for the VRMs would help either.
No, it doesn't.
Even with cooling, there aren't enough VRMs to maintain stable voltage under load (only three available). The solution is to get a system with a more robust power delivery setup so you can continue using that CPU. Or, if you prefer, wait for better benchmarks on the upcoming AMD Ryzen 3 or switch to Intel.

Not really.
Even with cooling, there aren't enough VRMs to maintain stable voltage under load (only three available). The solution is to get a system with better voltage regulation—ideally a 4+2 VRM setup for high-end chips.
I also considered downclocking. That could lower the voltage and ease the load, but I'm certain it would limit your CPU's performance.
