Question Mixing these 2 ram sticks is it okay?

[Lolfoollor]

I just want to ask I have a vengeance LPX 2x8 2666 mhz ram and a vengeance LPX 2x 8 3600 mhz ram. If I mixed them will there be a problem?

If there is, if I buy another 2x8gb 3600 mhz does it work?

Also,my computer shows my ram is only 2133 for all 4 of these ram and 1.2v only for DRAM voltage. Do I need to readjust this?

Additional Also I have activated the XMP and set it to 2666Mhz already. Using CMD to test using wmic still shows 2134 Mhz Ram. Do I need to do any test?

Mixing RAM not bought as a single kit even if it was the same make and model has a risk of issues. Also using 4 dims has a chance you won’t be able to run at rated high speed (3600mhz). Your best option is selling what you have and getting a 2x16gb kit.

How To - Troubleshooting problems with PC memory (RAM) and XMP profile configurations

In the beginning, there was......BIOS Before you go ANY further, go to the manufacturer product page for your specific motherboard model AND revision. Revision is an important aspect because for any given motherboard there may be more than one version of that model which will be identified...

Use CPU-Z to check the speed of your current RAM.

Thanks! As I removed my old 2666 Mhz Ram it shows 2666 Mhz for 3600 Mhz. When I tried to activate XMP to 3600 the computer just will not boot up. After checking a bit, I realized that my motherboard only can handle 3200 Mhz... ._. . Hence, I tried to active XMP to 3200 using the Asrock bios. The bios recognized that it is 3200 Mhz but for some reason CPU-Z is still saying it is running at 2666 Mhz. What do I do now?

Memory is guaranteed in the form sold, other combinations you decide to make have no guarantee to be compatible together.

XMP profiles are also for memory in the form sold. You can play around with other memory combinations with no guarantees.

Sorry I really didn't understand what you meant. Is there any other way to explain it?
