While some throttling can be expected in thermally constrained devices such as these, the speeds being logged are well below anything that could be described as normal. After that, the CPU happily speeded up past the base frequency of 2.69 GHz, to 3 GHz and beyond as needed. (Last upgrade was to 20H2) I got this fix somewhere on the net. In a message sent to TechRepublic about the matter, Microsoft said “We are aware of some customers reporting a scenario with their Surface Books were CPU speeds are slowed are quickly working to address via a firmware update.” At this stage, however, there is no firm time frame on when the patch will arrive leaving users with devices that are performing well below specification. This is the way I have fixed it these 2 times. Others haven’t, however, had any luck even when rebooting their Surface. Some have been able to workaround the issue by removing their devices from docks or connected AC adapters. Users have tracked the problem down to a Windows alert used by components peripheral to the CPU called BD PROCHOT that results in the CPU throttling down to protect it and any other internal components from overheating and suffering damage as a result. Sure, the Surface Book 2 has a powerful lineup of seventh- and eight-gen processors. According to user reports, the Kaby Lake-R-based Intel CPUs in both devices are throttling down to as low as 400 MHz and locking at this frequency. Microsoft Surface Pro series facing heavy throttling issues Microsoft is promising up to 50 percent more performance with its latest generation of passively-cooled and actively-cooled Surface. DELL G5 5587 (i7 8750H, 1060MaxQ,16GB RAM) problem, CPU throttling. It is similar to an issue plaguing Surface Pro devices, including this new generation, that Notebookcheck identified back in October however, if anything, it seems to be getting worse. As noted in a Reddit thread, Microsoft Surface Pro 6 and Surface Book 2 users are extremely frustrated with their devices experiencing the problem. The Surface Pro 5 encountered problems with ACPI drivers, which leads to random hibernation or sleep mode to be randomly invoked.CPU throttling issues aren’t new but it doesn’t make them any less annoying when trouble strikes. Since their launch, these devices have been plagued by various software or firmware related problems.īefore that, the Surface Book 2 encountered problems with the GPU disappearing in the Windows update and a bug patch leading to widespread BSODs. The throttle-locking is the latest issue affecting Microsoft Surface devices Surface Pro 6 and Surface Book 2 are throttling down. Microsoft is working quickly to fix the problem with firmware updates. If you are Surface Pro 6 systems users, you may have noticed that after you disconnect from the Surface Dock or other AC adapter, throttling will be disabled and others blame third-party antivirus software.Ī Microsoft spokesperson says that the company has noticed some customers reporting CPU slowdowns on their Surface Books. It is difficult to determine what component is incorrectly setting BD PROCHOT. In the last decade, there have also been reports of BD PROCHOT causing throttling on gaming-focused ASUS notebooks, suggesting that this functionality is a known one. I recently got my xps 15 2 in 1 with the i7 model, and I undervolted it by -0. However, given the spate of reports of throttling issues on Surface systems of Microsoft and the timing of the reports associated with the release of the new firmware, that means there is at least a correlation among them. The BD PROCHOT flag is neither unique to Surface devices nor new ones. Dell G5 5000 Gaming Desktop (or Dell XPS 8940) CPU cooler upgrade guide. This is a useful flag when the CPU is running within the heat limit, but other components bound to the CPU are running too hot due to the demands of processes on the CPU. Sure, the Surface Book 2 has a powerful lineup of seventh- and eight-gen. Im out of options, as there seems to be no real answer online. ![]() ![]() BD PROCHOT can be set by any peripheral and tells the processor to throttle down to lower the system temperature. Ive tried switching things around the BIOS, I tried creating alternative power plans, and setting the minimum CPU power usage to 50, 75 and even 100 in the existing 'Dell' and 'Balanced' power plans as well, but to no avail. It seems that BD PROCHOT - an Intel CPU flag causes this Microsoft Surface devices throttling issue.
