Does the checksum of files change when running virtual machines?

Question

Virtualization

I decided to check the stability of the virtual machines using a 20Gb static file as an example. I created such an archive and removed the checksum. Here it is: D3DB9FF4663AFFE1 (CRC-64). After I raised the virtual machine with MsSQL server, the checksum of the file became: CB628F2D5E3EAABE (CRC-64). In my opinion, according to the law, the checksum of the same data is always the same.
How did the hash sum change for a file that did not change? Why does this happen with intensive disk access?

Answer 1

Most likely, the disk is damaged so much that no memory controllers can compensate for this damage.
I would recommend checking the integrity of the disk using SMART and some other utility (I don’t rummage).
Well, buy a new drive, and transfer all the data to it.

Answer 2

Clean beech, change cooling or reduce frequencies.

Answer 3

Make sure that neither in the BIOS nor in the settings is overclocking for the video card. Yes, and for the processor too.

Answer 4

As I already wrote in another thread on the same problem,
Option one - you didn’t replace the thermal paste / you forgot to connect the cooler (or you need to replace the cooling) / messed up with thermal pads, etc. Take it to another service, describe the situation, ask after replacing the thermal interfaces to leave it on furmark for the night (a test that loads the video card), check it.
Option two - the video chip starts to fall off. If so, then in this situation there is a cheap option - competent and accurate warming up at this stage can still solve the problem for a rather long time - and an expensive, but sure one - reballing / replacing the video chip.
Also, as maagames.ru wrote above, indeed, just in case, try to reset the BIOS settings to default. Very unlikely, but not much.

Answer 5

uninstall amd drivers and see how it works
