Welcome
The reports come up as memory problems.
May I suggest that either the RAM that you bought was defective or you mixed and matched which is a BIG NO NO
May I further suggest that you RMA your new Ram and then buy all that you need all at once. Dont try to mix and match.
I will suggest a memory test as the slots may be bad, but I doubt it.

I brought the same vendor, same frequency ram's, can it unmatch? Take a look at spd screen in my first post, everything is the same, except timings.

Is there are any solutions except memory test? i will try to do that, but hope for another suggestion. I have more than a week till RMA expires, so i want to try out everything before doing it.

Your reports show a memory problem. You just bought ram. The only thing that I can think of is the memory test.

If it runs with some of the ram removed, the possibilites are limited
Bad ram
Bad slot
The memory test will show that and you have proof with the RMA if its the stick.

Added all of my rams, started scan and in 20minutes it gave me five erorrs in different places. SO for now i think i should first leave only my old rams, check them in all tests, then start adding other pieces. Just wondering, should i insert both of them in the same time or stick by stick and after every insertion do the scan?

Moreover, could you tell me how rams should be inserted? Then i had all of BSOD, my ram selection was like this:

1st channel:
yellow slot - old ram
black slot - new ram

2nd channel:
yellow slot - old ram
black slot - new ram

Does this have some importance? Maybe it would change something if i install old ones in 1st channel, new ones in 2nd or something like that? Just trying to figure it out.

The first thing that I would do, at this point, is to take a good stick and test each slot for at least 8 passes. The more the better.
If all the slot pass, I would then try to determine which stick is bad.
As far as inserting into the slots, the best way is to use trial and error. There are only a few ways that you could insert them.

Ok, so for now i have such a results:

One old ram in all slots - everything is correct.
Two old rams in all slots - correct.
Old and new rams together - errors.

Removed everything, added new stick in channel, already there are 1error in #4, 11 in #5 and 12 in #6 test. If the ram is bad, i guess the same errors should be in other slots too,correct?
