Dell laptop CPU running too low voltage
Dell laptop CPU running too low voltage
I'm using throttle-stop to check my CPU problems, and it seems the power supply is the main issue, almost always showing low performance during benchmarks. This is on my Dell Latitude 3520 laptop with an i5 1135g7. It has 16GB DDR4 at 3200MHz, 512GB SSD, 1920x1080 display at 120Hz. The CPU warms up initially but then fans speed up, dropping temperatures from 90-100°C to around 75°C. Even though voltage drops, the system still struggles. Record: 20240209-1432-41.9485139.mp4
This CPU model cannot be overclocked. The capability is missing from these processors. When performance drops, voltage adjustments follow naturally. The G7 line was built for energy efficiency. In typical laptops, they aren’t built for continuous high power or peak speed. Share a screenshot of the ThrottleStop TPL window if needed. Intel doesn’t officially specify a TDP limit for this generation. Earlier 10th Gen G7 chips usually had around 15W TDP. Your unit is already throttling at that level, which is normal. To boost performance, look at the MMIO Lock settings near the top right of the TPL window. Raise MSR PL1 and PL2 beyond 15W—try 20W or 25W—and observe the effect. Some Dell models use an integrated controller to cap power at 15W. If you push those limits but still hit the 15W ceiling, you won’t be able to overcome it.
I also tested it on an i5 1235U but it didn’t work, and it was using a HP laptop.
You can adjust the wattage of PL1 and PL2 but not their voltage. Share a ThrottleStop TPL image. Many companies such as Dell and HP impose a strict 15W cap. Some Lenovo models using similar Intel low-power chips can reach up to 50W, depending on whether the manufacturer enforces limits.
The yellow lock icon indicates that MMIO is secured. Are you pressing the OK button while leaving the TPL window? Using the X close toolbar button at the top right of a screen in Windows means you don’t wish to save any updates. Have you attempted adjusting PL1 above 22?
You're unsure about configuring PL1 or 2. Pressing Apply works while the program is running, but closing it removes the check.
It confirms your understanding. The clamp setting controls how much pressure is applied during use.
