Have you ever saw an screen like this? If yes, it could be
because your GPU has lost the sata connection to the drive. This may happens when you recently changed cables or when the fan is to slow because of dust and the higher temperature causes the
drive to overheat, wich leads to reading problems. Because SATA has an own data channel, these error ( memory cant get reserved :) ) can cause that the data doesnt get transported, while the
power controller ( trying to grab power assertion while already have one) is active and is sending open bus informations bac to the ALU and to the device manager.
"CPU FAN ERROR" - This error is currently being reported to many
users. This is currently due to an update. It seems like there is something in it. In the case of the error, the pressure values and speed values of the fan and / or the CPU cooler are not
sufficient. This is usually due to dust and a time exception in the DeviceManager. The temperature: It's burning hot.
If the pressure in the CPU cooling tubes is too low, dust will
be easier. Note the following tips to help keep your fan running even with the latest firmware issues:
1. Check all cables regularly and clean between them as they can
heat up and if there is dust this could lead to heat build-up.
2.Enough the pressure, because then less coolant can accumulate
(in the picture below you can see a drone image taken in the Yosemite National Park, it was taken much higher than the other and has a lower quality due to the lower pressure) ,
3.Open the BIOS or Hardwarecontroll and go into the section CPU
Cooling. With the function: Cooler control, you change the entry of Auto (adjusts the CPU temperature) to Manuel and select the highest possible cooling level. Restart the device and use it for a
short time (the preferences are recreated and the cooling system is "flushed".)
Errors at pins can be found when one cpu memory test of ePSA is
much slower than an other.
Video killed the radio star - With the current macOS error 670580, the title of this song is a perfect match, because a delayed security check from a file stream to the GPU results in a data jam in the RAM, which would be the place for the audio stream clogged. This causes the audio stream to stop.
Patient: I can not remember well ... Doctor: Ok, since when? Patient: What, since when? - Now this little joke, you can also transfer to some problems with the memory. For example, the error "memory could not get reserved, process could not load entity" may be a sign that a process (most likely a hardware-near process) left data, which was later overwritten because of a write error in the RAM came.
Such crashes that occur due to too many processes are usually the result of a so-called CPU hogging, in which case the CPU only plays a secondary role, the cause being mostly the main memory and / or the CPU cache's. Because often it is enough that a single process has a runtime violation and is therefore reloaded into the CPU L1 cache, which under circumstances can lead to a domino effect due to the full storage space, which can thus lead to the failure of an entire system. Thanks to the cooperative schedulers of the CPU`s, processes can be executed simultaneously and the CPU does not have to wait until the process ends the runingtime by itself, this is basically good, but in practice too enormous delays and lead to (preferences may have changed) errors.
However, for this intelligent process management to work, the CPU has to perform so-called predictions, which in fact can often pose security vulnerabilities. In the past, Kane exploited such a vulnerability to smuggle in a Zip bomb containing a virus.
You can help your CPU to minimize the load or optimize running time by following these tips:
If you are performing checks as loops or if-loops, then you should give up RAM before repeating
Delete the RAM (sudo purge)
Limit processes
Clear the L1 and L2 cache of the CPU at the first sign of a possible freeze. To do this, you must first invalidate the data in question so that you can get the rights over it. Then you just have to do a CLFLUSH.
Tips for Overwriting Data in RAM:
Perform RAM stress test regularly, as it will test the entire RAM and occupy it.
Activate the memory remapping function
Delete the RAM regularly
Build scripts that overwrite the RAM immediately after using blocks. Because if you just override a block, then the state of the transistor is irretrievably changed, which almost completely excludes semantic errors and freezes.
let gi = array (1e6) .fill ("data");
gi.reverse ();
const used = process.memoryUsage (). heapUsed / 1024/1024;
console.log (`$ {used} MB`);
If you are worried that a freeze might occur, or if the first signs of slowing down are already occurring, try to disconnect the RAM blocks or data stored in memory from the process. Just go to the activity panel and pick the main process that consumes the most memory. You end this process with the following Unix command: sudo kill pfid. After that, you can try out whether a purge is doing something.
Start anew
Stress your CPU and caches.
