So I bought 16gb of Corsair lpx vengeance 3200mhz and installed them successfully.

Can someone help me understand RAM speeds? This is what Speccy shows.

Is the above 1067 mhz the speed at which my RAM is currently running at? shouldnt it be 3200 mhz? It needs to be tweaked in BIOS or what?

Any intel is welcomed. Thanks

PD: Sorry for the ignorance, this is the first time I build a PC myself and I did try to google, but what I found was quite confusing.

It's running at 2133mhz, you have to double the 1067 because of DDR (double data rate). For your RAM to run at its advertised speeds you need to enable XMP in the BIOS.

DDR4 memory has a Double Data Rate (DDR), meaning your DDR4-3200 is rated for a data rate of 3200 MT/s and a clock frequency of 1600 MHz.

It's currently running at 1067 MHz = 2133 MT/s, which is the default speed for most DDR4 memory when first installed. To get the full DDR4-3200 speed you'll want to enable XMP and pick the 3200 profile. That's done in BIOS/UEFI.

Thanks to you both for the fast reply and clarification!

Is there any downside or side effect of having my RAM run at full speeds? Also, performance should be higher, right? Does that increase in performance come at any cost?

Thanks!
