Pairing 3466 & 3333 memory @ 3200. Issues?

[ThisIsCheez]

Quick rundown.

 

I currently have 2x8gb of the older style Corsair Vengeance RGB that's been discontinued. They are 3466MHz modules (Got these couple years back when the memory shortage was going on and they were somehow cheaper than 3200MHz) running at 3200MHz since that's the max my motherboard supports. I've wanted to upgrade to 32gb (4x8gb) but it's really hard to find the original Vengeance RGB and when you do it's expensive. I found some used for sale that are 3333MHz for a solid price and want to pick them up. Here's where my question starts:

 

As long as the memory timings are the same I shouldn't have any compatibility issues, right? If I was running 2133MHz and 3200MHz I could see a problem but since I'll be clocking both sets lower than what they are rated for I don't foresee any issues but I wanted to get a 2nd opinion.

You can mix ram speeds when the IC chip is the same, e.g. Samsung B die with Samsung B die. You an use typhoon to check your die.

 

My personal advice would be to sell the current ram on eBay and buy new RAM.

Does most high end memory use the same IC or is it completely random like with GPUs?

 

Edit: I checked the pics he posted and it looks like they are ver 4.31 which is the same version my modules are.

idk how corsair does their ram.

 

there are 3 different companies<micron, samsung, hynix> and they each have different dies.

Looks like the version on the module tells you the IC type.

than you'll be okay mixing ram.
