Anchor point of the object. How to fix or why this happens?

Question

laptops

Why does an object always "fly off" the central point? When creating via Shift+A, the point is in the center of the object (logically). As soon as we slightly edit the object, let's say extrude "E", it remains outside the center of the object. If you edit a couple of times and let's create copies of "Shift + D" by moving it to Object / Edit Mode, then the points often remain damn where, absolutely outside the object (you can see on the screen) Adequately twist (because the point of the object is somewhere out of sight) , and moving without using G is extremely difficult. How to fix it?)

Answer 1

First, your laptop supports a total of up to 16 gigs of memory.
Secondly, it has a connector for DDR3L RAM, the L attribute means low power consumption, these connectors use a voltage of 1.35 V, conventional DDR3 will not work for it, they use 1.5 V, and the second die that you inserted is just DDR3 .
The difference in frequencies, in principle, does not play a big difference, even dice with different frequencies should work together at the lowest frequency, however, sometimes there are problems in the compatibility of modules from different manufacturers, so it is recommended to take dice from the same manufacturer with similar characteristics, or the most common and universal, e.g. Kingston.

Answer 2

It's a bad idea to make friends of different frequencies. Even the fact that they are from different manufacturers is not good.
Your laptop supports 16GB, so it's better to buy two 8GB sticks for complete happiness and install it. Remember: Type - DDR3L SODIMM Frequency - 1600 This will work for sure. As for the frequency in CPU-Z, it should be 800 (real), and the effective 1600, because it uses double data transfer rate (DDR), at which data is exchanged twice during one DRAM tick.

Answer 3

There should have been a decrease in frequency and work. maybe update the bios, it's not difficult from Windows. But if the chip is not in the BIOS, then the OS will not be able to work with it. and here is the fact that GPU-z Report please attach.

Answer 4

Perhaps your laptop does not support this amount of memory.
