I adjusted the clock speed and voltage of my CPU but have a few queries.
I adjusted my CPU by lowering its clock speed and reducing the voltage, using Tech Yes City's instructions for a fixed core ratio and offset settings. Temperatures dropped significantly—now around 62°C during gaming instead of 78-80°C previously. Cinebench scores only fell by 104 points. I have some concerns: Was this approach safe? My CPU’s max voltage was low (1.006V according to Hwinfo64), which feels unusual. After setting the core ratio to 40.00, it doesn’t downclock at idle and software still shows 3998Mhz. Is this typical behavior, or does the system actually downclock but the software ignores it? Where should I check for idle downclocking activity?
From a hardware standpoint, reducing voltage is generally secure. It lessens the load on the CPU by supplying lower voltage. The only drawback is potential instability—though in theory it might lead to data corruption—but the chances are extremely low. In about 999 out of 1000 cases, the only outcome would be a hard reset of your computer. 2. A very low maximum voltage is set, but your aim is to decrease it further. As long as stability remains intact, it should work well. 3. You mentioned a fixed core ratio, which means it stays constant. To allow adjustment, you'll need alternative undervolting techniques.
It seems Intel is adjusting the suggestion to use PBO instead.
Surely, locking the clock increases its power consumption unnecessarily during inactivity. Average idle voltages tend to be significantly reduced with a curve offset, allowing the CPU to lower its clock speed or enter sleep states when not in use.
I'm exploring various approaches to find the one that suits me best. Time was tight, so I might dive into PBO optimisation later since it requires more adjustments. There aren't clear 5700x guides available, and most focus on 5800x, which should still be effective as they're quite similar.
I disabled the manual underclocking I had earlier and activated Eco Mode in BIOS. Temperatures are now lower, and performance dropped slightly by 687 points in Cinebench R23.
Adjust the curve optimizer in PBO settings, modify power limits (PPT, EDC, TDC), and lower core voltage. Fine-tune for temperatures around the mid-70s if desired. With some adjustments, you can achieve 4.65 volts across all cores while maintaining good temps on a reliable cooler. It’s unclear what specific steps were recommended in Tech Yes, but you should see improved performance compared to the stock 5800X with controlled temps using a decent cooler.
I updated the setup by removing the TechYesCity manual UC+UV since it was causing excessive PPT and EDC values. I also excluded the eco mode, as temperature changes during gaming weren't significant and it sometimes showed clock stretching. For now, I'm keeping it on factory defaults. I won't adjust it further because I plan to play at night when it's cooler, and it's too bothersome for me.
