[SOLVED] Mixing RAM of the same brand but different MHz and timings

[Deleted member 2720853]

So, I have two 16 GB sticks of Corsair Vengeance LPX memory running at 2400 MHz with 16-16-16-39 timings (CMK32GX4M2A2400C16) laying around being unused, since I replaced them with two 16 GB sticks of Corsair Vengeance LPX memory running at 3200 MHz with 16-18-18-36 timings (CMK32GX4M2B3200C16).

I don't really want to try this, I'm just curious. My motherboard (Z390 Aorus Pro) has 4 RAM slots, so is it possible to use all four sticks? I know it will run at 2400 MHz but I'm wondering if I can make them all run on the same timings or something. Would that give me 64 GB of RAM running at 2400 MHz?

The only way to know for sure is to try it...you already know it will likely run all sticks at 2400, if it works at all, so I would just sell the 2400 and buy two more sticks of 3200.

Nah I'm not planning to go to 64 GB, 32 GB is already overkill, was just wondering

It may not run at all. It also may not even work at 2400Mhz. It may only work at 2133mhz. As the SPD speed on the 3200Mhz memory is 2133Mhz. Although with manually tweaking timings you may hit 2400Mhz. Who knows perhaps even higher with manual tweaking.

You can test it and see if it boots or not and at what speed. If you want guaranteed speed and compatibility. Sell all the memory and get a factory matched set.

Ah, forgot about the 2133 MHz. I'll sell the 2400 ones, and not buy any more RAM because all I really do is gaming and YouTube, you don't need 32 GB for that but here I am
