![]() In this new model, CPU cores and GPUs access the same memory. SoCs can run faster, use less power, and stay cooler, and when built in large quantities are considerably cheaper – all advantages which Apple has used in its products, but only now in Macs. If you’d like to read a more technical account of some of the issues which have brought unified memory to Nvidia GPUs, you’ll enjoy Michael Wolfe’s article on the subject.Īt the same time, chip design has changed, with far tighter integration of what have been separate chips into a System on a Chip (SoC), a field in which Apple is one of the leaders, largely as a result of its hardware development for iPhones and iPads. So long as CPUs and GPUs continue to use their own local memory, simply moving data between their memory has become an unwanted overhead. GPUs are now being used for a lot more than just driving the display, and their computing potential for specific types of numeric and other processing is in demand. There are problems with this architecture, though. Main memory isn’t shared between the CPU and GPU, although ironically more basic designs, such as laptops with simpler graphics, may use main memory rather than the faster chips of a graphics card. This has allowed graphics cards to have less, faster and more expensive memory which is only accessible to the GPU. You can also buy a basic version of that model with little main memory, and upgrade that when you can afford it. It’s eminently upgradeable by the user when you can afford a better graphics card, you can replace the existing one with a faster GPU and more graphics memory. Then there are peripherals like disks, which have their own interface modules, and the display is driven by a separate graphics card. There’s the processor and memory as memory management becomes more complex, the two get a bit more intertwined with a separate or integrated memory management unit. Previous hardware architectures have largely been modular. This article looks briefly at what this means, its consequences, and where the M1 and its successors are taking hardware design. Still check the monitoring table to make sure it shows lots of zeros.One of the major new hardware features of Apple Silicon Macs, including those launched on 10 November, is that they use “unified memory”. If ThrottleStop does not find an INI configuration file when it starts up, it will read the default voltages directly from the CPU. If you do not want to do this, you will need to shut down Windows, boot up and do not run ThrottleStop or run ThrottleStop without the ThrottleStop.INI configuration file. It will remain however it was previously set. If you switch to a profile and Unlock Adjustable Voltage is not checked, ThrottleStop will not make any changes to the voltage. Create 2 separate profiles in ThrottleStop and you can easily switch back and forth between under volting and no under volting. You also have to check this box when you are setting your voltage to zero. You need to check the Unlock Adjustable Voltage box when setting your voltage. Make sure that table shows 0.0000 in the Offset column. This table shows you the voltage values that the CPU is currently using. There is a monitoring table in the top right corner of the FIVR window. Set a profile in ThrottleStop and force the under volt to 0. Here is what happened to one user that ignored the TS Bench errors.įollow that forum to the next page for some more real world results. If a CPU cannot calculate a consistent answer to a problem, sooner or later this is going to cause a problem. "I can play games on my computer for hours without any problems." Just because a computer does not crash does not mean that it is stable. All of my computers can complete the TS Bench test without any errors. Give your CPU more voltage until the TS Bench can complete with 0 errors. If you are under volting then you have definitely gone too far. If the ThrottleStop TS Bench is reporting errors, it is telling you that your CPU is not 100% stable. ![]() Your computer is adding up 2 + 2 and maybe most of the time it is adding that up to 4 but sometimes it might be adding that up and getting an answer of 5 or 105 or 1,000,005 or some other random value. If you ask a stable computer to add up 2 + 2, it will give you an answer of 4 each and every time. If the results are not consistent then it flags that as an error. It calculates the exact same problems 2 times and compares the results. The TS Bench does millions of calculations.
