[SOLVED] Different Speeds

[tamir.ayoub2003]

Hi everyone, I've been wondering about getting a new stuff for my PC, but first i would like to tell you my sad story xD,
So uhm about a year and a half ago, my dad took me to a store in my city and bought me a PC to edit it and turn it into gaming..
So after a time I got my self a new ram for it cause it had only 4gigs of ram ddr4 2133 mhz, got another stick 4gb and it worked fine also i got a gtx 1060 and put it on with a new PSU 450w BT,
So after about 2 month a friend of mine gave me a better cpu so i decided to change the whole motherboard, so i got my self a gigabyte B250M 6/7th gen, and now we got to the moment and the sec that i thought about getting more ram,
cause let's be honest 8gb isn't that great in 2019, so when i searched well in my pc i found out that my 2 ram sticks don't go well together if i put em into 1 slot..
So i searched and found out that my old mobo was limiting the speed of my old ram.. and it's a 2400mhz ddr4 4gb (1200), and my new one is 2133mhz ddr4 4gb (1066) ,
I mean they are working just fine but they aren't going well together and they refuse to be put in 1 lost, so in that case if one day i decided to get my ram into 16gb of ram,
what am i suppose to do?
get a stick that works with the 2400mhz ddr4 4gb (1200), and another one that works with the 2133mhz ddr4 4gb?
or do i have to change all of them?
and btw am still young about 16 years old so i don't have enough money to afford whole new rams so i was thinking if it was going to work?


PC Specs:
CPU: i5-7500
GPU: GTX 1060 6gb
PSU: EVGA 450w BT
Ram: as said on top one stick is ( ddr4 4gb 2400 mhz (1200) ) and the other one is (ddr4 4gb 2133 mhz (1066) )
mobo: Gigabyte B250M-D3H-CF
hdd: wd 1 tb blue
OS: windows 10 pro 64-bit

I hope you can help me with this and btw as u can see from my motherboard it has 2 diff color in ram slots ( black & grey) so that's why am thinking it will probably work if i put each one with a similar one to it?
and thanks in advance.

mix-matching RAM is always a gamble. If it works, then great! But if it doesn't, it's not that strange at all. The recommended way of installing RAM is using the same set-up (speed, voltage, CAS, etc.).

So what do you think i should do?
bring a similar ram to for each slot ?
or remove 1 and get a match with the higher one? i don't suggest i do this because it cost more money but i want to be 100% sure

This will be a gamble, whether it will run smoothly depends on your luck.

or remove 1 and get a match with the higher one? i don't suggest i do this because it cost more money but i want to be 100% sure

This one will be the preferable option, since the chance of it running smoothly will be higher than the first option.

EDIT: many people claim they are fine with mix-matching, and it work well for them. but some people claim it ruin their stability, so really, its a matter of whether you are willing to gamble or not.

so uhm i already mixed and it worked fine, so if i mix it more it might not work ?

Correct.
Any 2 or more RAM sticks that are not sold as a set may or may not work.

A works fine
A + B works fine
A + C fails
B + C works
B + D fails

etc, etc, etc.

So u think i should give it a shot to get a similar for each ? or just go and do whats safe?

Up to you. It's your time and money.

Probability of success is somewhere between 0% and 100%.

Any set of RAM that does not come in the same package may not work.

what if i bought a ram package 2x4 ddr4 2400mhz?
and took off the 2133mhz and kept the rest? while putting the 2400mhz new one together and old alone?
is it going to have a higher sucess rate?

1 stick in package = tested by factory to work
2 sticks in package = tested by factory to work + together
4 sticks in package = tested by factory to work + together.

Nowhere in that is package with one stick tested to work + together with package with 2 sticks. By default, you become the tester after buying new ram. Sometimes it works, sometimes it works after making adjustments, sometimes it just laughs at you and says 'not gonna work!'

Best bet always is buy 1 package with all the ram you want. If you want 16Gb, buy 2x8Gb in 1 package, sell other ram.

If ram IS going to work, it'll always be at the worst case. That means worst timings, slowest speed, highest voltage. Any ram you add that's more than 2133 will run at 2133, the cpu doesn't see 4 sticks, it sees 1 unit of X amount of ram at 2133. So to get 2400 you'd have to remove the 2133 totally. And even then there's still no guarantee it'll play nice with the new ram.
