Question Did I screw up my PC after upgrading the RAM with different Mhz ?

[MJarcos]

Greetings,

originally, I was using 2 sticks of Corsair VENGEANCE® RGB PRO 16 GB (2 x 8 GB) DDR4, CL 18 - now with another Corsair Vengeance RGB RS, 16GB, 3200MHz, DDR4, CL16. Although it appears to be working correctly, some games (Call of Duty Black Ops 1 and everything related to Unreal Engine 4 and 5) are having problems running, however, I had no problems with Postal Brain Damage or Sonic Unleashed Recomp, or even the Heaven/Fur benchmark and Unreal Engine SDK. Which is strange, after all. these are, in theory, more demanding games, right?

The interesting thing is that the performance did not return to normal if I use only the original memories or the new one. Besides thats, the computer is running fine. No bluescreen, no crashes or something like that. I have already reset/update the bios, cleaned the parts, activated XMP profile one in the BIOS. Did I ruin my computer?

PC Specs
Mobo: Gigabyte Aorus B450 Aorus M, AMD AM4, mATX, DDR4
PSU: XPG Core Reactor, 750W, 80 Plus Gold Modular
GPU: RTX 3070 Ti 8GB
OS: Windows 11 24H2
CPU: AMD Ryzen 7 5800X 8-Core

Thank you

Some more clarity is required to really get to the bottom here. It's not clear if you got two more memory modules or just one. The speed of your original is not listed though mixing latency isn't always a very good idea either. I am assuming you added the new memory to the original and are running both.

Also what are the games which aren't working as expected doing?

If you're trying to get more memory capacity the best choice would be buying a 32GB DDR4-3600 CL16 kit and just use that by itself.

If you hadn't already done a BIOS reset with just one memory kit in you can try that, but anything else really needs more information.

Thank you

only use 1 kit of 2 sticks the issue you have if you have 3 sticks

is it will run duel channel till it needs the last stick then it will run in single channel.

if you want all 4 slots full

you need a kit of 4 ( this offers more bandwidth.)

2 stick kit you can usually get higher speed ram of 3600 with low cl of 16. running.

ram sticks come in pairs for a reason when in kits there timings match.

The original kit was 2x8GB. I added a 1x16GB.
About the speed. You talking about this?

Could be some apps are more sensitive to memory running in single or dual channel than others.

PCs have become so complicated that you can’t just add a stick of ram like in the good old days, you basically need kits of 2 or 4 sticks to guarantee it’ll work ok.

I’d put back the original ram and reset the bios so it’ll “relearn” what ram is installed. Hope you can trade in the 16GB stick for a 32GB kit of 2 sticks of 16GB each.

You WILL have issues with mismatched ram.
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.
Ram must be matched for proper operation.

Run memtest You should be able to complete a full pass with NO errors.

If you want to try to get things to work, balance the capacity across two channels.
Your motherboard manual should tell you which slots to populate.
In the bios, increase the ram voltage a bit at a time.
You may have to go as high as 1.45v

Per @geofelt

"Your motherboard manual should tell you which slots to populate."

Yes. Also keep in mind that some motherboards require that the first physically installed RAM be placed in a specific slot. Typically DIMM_A2.

That requirement may or may not be obviously stated. Check all fine print and any RAM related diagrams.

Thank you

Yeah that reveals everything necessary. You've added a single module which is bad because it messes with the system's ability to run dual channel correctly. That module is also slower than your original ones are. For memory on anything that runs dual channel you have to add it in pairs and in the correct slots.

I'd suggest returning the 16GB module and getting a 32GB kit as I mentioned in my first post. Then make sure you're installing them in the correct slots.

Is there a problem i return the 16Gb stick and buy the same 2x8GB kit again to reach 32GB? (Corsair VENGEANCE® RGB PRO 16 GB (2 x 8 GB) DDR4, CL 18)

As long as you can return it easily should it not work trying that may be worth the money savings.

It might be a problem, but it may also work fine. When you install 4 DIMMs in a dual channel system it can be harder to run the proper frequency. Typically the speed you're looking at should be fine, but depending on the motherboard and CPU it may not be. That's why I suggested a 32GB kit because that removes all question.

Thank you. Also, is there a reason why some of my games are running worse? Even after i remove the 1x16GB stick? Im getting lag/shuttering that never happened before.
Games im having problems: The Division 2, Call of Duty Black Ops 1, Expedition 33.

Thank you.

Here's a screenshoot from my memory test: 2x8GB only.

Don't do that return the 16GB stick, sell the 2X8 set and buy a 2X16GB set as in one package.

I bought the 2x8GB kit back in 2022.

Hard to say for sure what it could be as I've never put mismatched modules in like that so I'm not sure if that causes any issues. I'd start by making sure the memory is in the optimal slots (DDR4_1 and DDR4_2 according to the manual). If that doesn't work (or this is where they're already installed) reset the BIOS to defaults and go from there.

Also if any of your storage is SATA just double check and make sure all the cables are plugged in well.

make sure your 2 sticks of 8gb

are in slots 2 and 4

go into bios make sure xmp is enabled it may have disabled itself when you added the extra memory.

if issue presists

reset bios to default values
and save

then re-enter the bios and set up XMP again.

Hey everyone. I return the 16Gb stick and ordered a 2x16GB kit "Corsair Vengeance LPX, 32GB, 3600MHz, CL18". I'm gonna keep the old kit in case of problems. About the GPU problem, i managed to solve it too. I decided to use an old RX550 i had lying around to check if the problem was the GPU. After the change, it worked. I decided to try the RTX3070ti again and it worked. I guess after the stick change, something happen and the mobo got confused about the GPU.

Anyway, thanks everyone for the help and info about RAM sticks!
