Swapped out the CPU in your laptop, and it's now throttling when temperatures drop.
Swapped out the CPU in your laptop, and it's now throttling when temperatures drop.
Hiho, your recent upgrade from the i5 560M to the i7 740QM seems to be working, but there are a few observations. The CPU is running at about 10W more, which aligns with Intel XTU warnings of throttling despite temperatures around 45-50°C. The HWMonitor shows only 14W usage, matching the expected 45W for a 45W processor. Thermal Grizzly cooling helped distribute heat evenly across the die. The GPU also performs well at 48°C with stable frequencies near its base of 1.73GHz. In Cinebench R15, performance dropped significantly to around 115 instead of the usual 270. You're using an AC adapter and all Windows performance settings are optimized. If you want better results, consider checking cooling solutions or adjusting thermal throttling limits.
You're not well versed with the Sonys, but in the Dells, when they get upgraded with quad-core CPUs, stronger power supplies (around 90W+) are necessary. The firmware then limits their performance to prevent instability caused by an unsuitable PSU. It's wise to check if this applies to the Sonys and get a higher-rated adapter if needed.
Adapter rated for 120w works well. Yet Intel XTU still throttles despite normal temperatures. What could be causing this?
Are you certain the restriction comes from heat? You might want to boost the voltage since your new CPU requires more power.
Begin a fresh discussion instead of reviving an old one. For Intel processors, consider using ThrottleStop. If your system hangs at low speeds, try clearing the BD PROCHOT configuration.
It's been quite a while since we last spoke, and this was a short-term task. I won't be able to recall the details now.
