You can see that the package power is constantly hitting the 56W mark (right top) and the CPU frequency is extremely stable. The cpu frequency of the machine is now solely limited by the power limits of the VRMs. Temps are now going up much slower, even without thermal throttling at all. Solution2: I repasted the CPU/GPU with another thermal compound (IC Diamond 24carat). Temperatures recovered after the fans kicked in and it stayed around 85☌ to ~91☌ with nervous thermal throttling sometimes. The problem was that bumping up the speed of the CPU at the beginning of heavy load, lifted up the temperatures of the cores to >95☌ and the machine began throttling in an instant. Problem2: CPU temps were not too bad out of the box. You cannot do a lot against the power limit throttling (which is good), but thermal throttling can be solved completely with this machine. The i9 of the XPS has a power limit of 56W permanently (please correct me if I'm wrong), or 78W (short turbo boost period). There are different types of throttling a) thermal throttling (CPU/GPU/VRMs) are getting too hot and b) power limit throttling (the machine has a power limit which can't be exceeded by a single part or the machine as a whole). You can prevent the newer (faulty) drivers from being installed e.g. ![]() To solve this problem, download the Intel Thermal Framework from here: (edit, new link to DPTF drivers Version 7.5567, A09: - just confirm the prompts "the driver will be replaced by an older version" stuff. It seems like some Intel Software updated the Thermal framework to the newest version, which renders your machine unusable. Uninstalling it did not go well (it keeps coming back, no matter what you try.). Solution1: After a long forensic work and forum reading, I managed to identify the " Intel Dynamic Platform and Thermal Framework" as the cuplrit. After around 5 Minutes, everything went back to normal. Apart from that, the system didn't use the Nvidia GPU anymore but switched to the Intel GPU. Problem1: After a few minutes, the CPU clock was reduced to the minimum clock speed of 0.78 Ghz. Fortnite, rendering, Cinebench, AIDA64, etc.): Problems I ran into while the machine was under heavy load (e.g. This "Core i7" processor supports Hyper-Threading (it has two threads per core for a total of eight threads for the system, effectively four real cores and four virtual ones) as well as Turbo Boost 2.0 (the system can dynamically increase the processor clockspeed to 3.8 GHz when tasks demand).Since I spent around 20 hours in the last four days with benchmarks, testing and thermal issues, I have now a great setup which I would like to share with you. Each core has a dedicated 256k level 2 cache and all processor cores share a single 8 MB level 3 cache. Processor Speed: 3.4 GHz Processor Type: Core i7 (I7-2600)ĭetails: This custom configuration is powered by a 32 nm, 64-bit Intel Core i7 "Sandy Bridge" processor with quad cores (four independent processor cores on a single silicon chip). You should have no problem upgrading to this, but I would stay with a known Apple version of it: ![]() However, this processor supports an LGA 1155 (H2) socket and it is possible to upgrade the processor to some extent. Apple iMac "Core i5" 2.7 27-Inch (Mid-2011) Specs Identifiers: Mid-2011 - MC813LL/A - iMac12,2 - A1312 - 2429ĭetails: *Officially, Apple provides no information about whether or not the processor in this model can be upgraded and the company does not intend for one to upgrade the processor either.
