upgrade my system with RAM DDR3 & SSD

[VH2000]

First question & first step:

How big is your disk  ? GB and your  C-Partition right now?

Open Diskmanager, make a screenshot or photo by mobile phone and post the result.

Download "Media Creation Tool" from Microsoft.

HDD is 500GB

Clone to: 

SSD 500GB

[VH2000]

That is not the full answer to my question

[lse123]

The PC is of a friend of mine

Is Not at my place now

Soon reply

Probably tomorrow

the 6200 MT (Micro Tower) and the 6200 SFF (Small Form Factor) use exactly the same motherboard only the case's are different

are you confusing the 6200 with the 6300?

6200 ram load order

https://www.manualslib.com/manual/575260/Hp-Compaq-6200-Pro-Sff.html?page=7

6300 ram load order, there are two memory banks, and each bank has two dimm slots for a total of 4 dimm slots

bank 0 is the two slots farthest from the cpu, bank 1 is closest to the cpu and all banks should be running the same size dimms for best speed but you can run say two 8 gb dimms in bank 0 and two 4gb dimms in bank 1

also, you CANNOT run 3 dimms in this motherboard

If I remember well

I unscrew up my friends PC case

and we find 2 x 2GB in the BLACK slots - B-W-B-W

We removed these and installed in the 2 BLACKs slots the 2x8GB RAM chips and in the 2 Whites slots the rest from before 2 x 2GB Chips 

is an error with this?

I will update here soon --- if when my friend startup his HP PC 6200 Pro for the second time, if appears the message again???

[VH2000]

8 GB ==> Black slot

2 GB ==> White slot

is correct. 

The message from the first picture should not appear again when you boot the second time

You can check the FSB frequency with CPU-Z 

[lse123]

YES THAT'S WHAT DID:

8 GB ==> Black slot

2 GB ==> White slot

is correct.

MESSAGE NEVER APPEARED AGAIN --- MEANS ALL OK, EVEN RAM STICKS 8-2-8-2, NOT ALL OF ONE SIZE...?

About the message in this Post,  previously:

VH2000

Message 9 of 18: 

1

What do you mean by...? What do these 2 CLI commands? >>>

Run an Inplacement.
Run these 2 commands in cmd (admin)
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

If the current HDD is having errors, do these have to be fixed before I clone it? How do understand has errors?

2

What do you mean by "MSR " Below...?

All recovery processes fail due to the MSR partition!

3

So, Is it required to do a Disk C:/ backup in Windows10/Acronis, and after clone HDD System disk, to SSD with boot from DVD ACRONIS MEDIA...? 

Then, upgrade to Windows 10 21H2, from 20H2,... only after clone did and replace HDD with SSD... then UPGRADE more quickly,... Is ok...?
