Mixing RAM

[remo233]

I have an i9 9900 pc build with 2 sticks of corsair 8 gb ram, CL 16 2666 MHZ. Asrock B365M motherboard.

I saw a good deal for kingston fury ram, 2 sticks of 16 gb ram- CL16 2666 MHZ. I bought this ram.

 

Will there be any compatibility issues if I have different makes of RAM in my system? I will have the two corsair sticks of 8 gb ram in slot 1 and 3 with the 2 16 gb ram sticks of kingston ram in slots 2 and 4.

If you've already got the ram, I'd try it. My 9900k has 48gb. All 4 stick are Corsair. They have different brand chips on them. A kit of 3000 and a kit of 3200. I was able to get them to work just fine at 3200. 

 

Worst case, it's unstable and you just remove the 2 8 gig sticks.

LTT has made a video about mixing memory, I recommend watching it if you're interested in learning more.

There can be, it could just be fine. There's only one way to find out. In my experience with DDR4 the odds of it working are something like 80% that everything works as expected, 15% that it turns on but XMP doesn't work (that's assuming a 3200-3600 rated kit, the odds should be a bit better for XMP to work at a speed that low), and 5% that it doesn't even turn on. It should more than likely work, but there is a chance that it won't work. 

 

If it doesn't work, stick to the two Kingston sticks and you should be OK.

Just be sure to clear the cmos before firing up the new configuration. I once ran 3 different kits on X58

Thankyou everyone for your help, the linus tech tips video was also good. Mr ordered ram arrives in a few days, I believe it should be fine.

Ok so it turned out to be a bad idea. I had fps drops on my pc after installing the new ram, this occurs after a few days of using the PC where ram usage gets higher. I could fix it by restarting the system but was a headache. I originally thought it was some other issue but after taking out the ram, system was back to normal. Have now bought two additional sticks of the same corsair ram and everything is good.
