This should not be "dynamic speed" feature, because the frequency was LOCKED as a straight line. Watch Limit Reasons.I have 2 Macbook Pro, both manufactured in 2011 Early, 13 inch and 15 inch.īoth suffered from same issue: CPU was throttled at 0.8GHz, statically, as the below image above: You might see some throttling in this test. The R20 test uses the AVX instructions so it will need more power and will create more heat. It takes longer to complete compared to Cinebench R15 and is also a more strenuous test compared to R15. Then they have stability problems when their CPU is only partially loaded because they never did any testing of that.Ĭinebench R20 is a good full load test. Too many people only do full load testing. One or two threads of Prime95 is another good partial load test. Using the TS Bench test and selecting 1 or 2 Threads is a good partial load test. When adjusting voltages you need to do full load testing as well as partial load testing. Did you do any stability testing of those values? How did you decide that those numbers are correct for your CPU? Did you watch a YouTube video and copy some numbers that worked well for a different CPU? Intel default for this offset value is 0 so your CPU will still be within spec no matter how you adjust this.Ĭlick to expand.When is your laptop not stable? You are using a -90 mV undervolt for your CPU core and CPU cache. Limiting the maximum temperature can limit maximum performance. If the PROCHOT Offset feature does not have a Lock icon above it, I would change PROCHOT Offset from 8 to 2 or 3. It looks like Lenovo is low balling that down to 92☌. The Intel default thermal throttling temperature (PROCHOT) is 100☌. Best to set it to its maximum value, 255.75 so it does not interfere with performance.Įdit - Also post a screenshot of the Options window. In ThrottleStop you can increase the Core IccMax current limit in the FIVR window. This will tell me what I need to know accurate CPU speed, temperatures and any throttling. Post a screenshot of ThrottleStop while your computer is running CInebench R20 with Limit Reasons open. This is not BD PROCHOT related so for now you can leave that checked. Lenovo used a few different methods to randomly disable Intel Turbo Boost. It will show you why your CPU is throttling. When running the test, open up the ThrottleStop Limit Reasons window. Tests like Prime95 or OCCT are a little overwhelming for laptops. A setting of 0 is for max CPU speed even when idle.ĭownload a more practical test like Cinebench R20. A setting of 128 can limit maximum performance. On the main screen set Speed Shift EPP to 80. For the 7700HQ, typical values are 1 and 38. The Range box will then tell you appropriate values for the Speed Shift Min and Max. Open the TPL window and check Speed Shift and push Apply. In ThrottleStop you have Speed Shift EPP checked on the main screen but Speed Shift is not yet enabled so this is doing nothing. Laptops with 6th and 7th Gen CPUs support this feature but many did not enable this in the BIOS like they should have. The first problem I see is that your computer is not enabling Speed Shift Technology. I open the Intel extreme tuning utility and take a look and it does indeed report it as "Current Limit Throtteling: yes", So I increased the turbo states allowed wattage (as the sliders are in IXTU) as well as core IccMax and it jumps right up to the proper 3400Mhz. It also hits Max Turbo Limit every now and then that flicks on and off.įor the sake of testing I put the fan on to 100% and it now jumps between 3200Mhz and 3400Mhz, with 3400Mhz being the all core turbo frequency.Īt this point I would suspect the reason I do not get a steady 3400Mhz which is the all core turbo would be the short power max, turbo boost power max and turbo boost power time window settings you can normally poke at in BIOS (or Intel Extreme Tuning Utility in my case). I do not know how HwMonitor operates but in Hwinfo you can see performance limit reason.Īfter running OCCT for a while it has dropped down to 3-3.2GHz at about 80c, hwinfo lists limiting reasons currently as Max VR voltage, ICCMax, PL4 and package-level RALP PL1. It was at least 2 years since I last cleaned it. And I have for the most part neglected proper care of my Y520 for many years. Have you cleaned it? How warm is it at your place? its rather chilly here with ambient being around 19c. I have a Y520 myself, figured I would run OCCT and see if mine behaves the same way.
