i would like to talk about my experiment with two different ram speed in same machine, 2666 and 3000 Mhz

so about 2 months ago i got a used gaming pc and the ram was corsair vengeance 8gb dual channel 2666 Mhz, it was so low that one time i got system error that says "Out of memory" so i started looking for an extra 8gb like the one i have but no luck finding it in my area, i only could find 2400 and 3000 Mhz, so i got 3000 Mhz and stared to install it, at first i did't get any luck at installing it so i had to rearrange the ram channels, the 3000 in first slot and the dual in the 2nd and 4th, it was working fine but it 2123 Mhz, so i increase the speed to 2666 , most of the games wouldn't even load so i stared searching and i found that i had to increase the voltage, it was it 1.2V, so i increased the voltage to 1.3V and i worked like a charm , iv been using it from about a month and i hadn't had crashing or anything."i did not modify the timings"

That's great, that you were able to get them to play nice with each other.

I wish they make RAM with a "better handshake" when using unmatched modules.

I imagine it that will be something like this:
Ram 1: Hey there...
Ram 2: Hi.....so it looks like we're going to be...
Ram 1: Dual Channel neighbors. I could go as fast as 3000MHz.
Ram 2: Awesome, but I could just hit 2400MHz
Ram 1: No problem I could run at little slower to match your speed.
System boots into BIOS.
