Hi. I'm currently running a Ram configuration of 4x4GB Corsair Vengeance LPX DDR4 at 3000mHz and I was wondering if I can replace 2/4 modules with a pair of higher speed 2x8GB Corsair Vengeance RGB Pro DDR4 @ 3200mHz. My main concern is even will I be able to run the 2 pairs of Ram in dual channel in 2 different speed (3000 with 3000, 3200 with 3200) since AMD doesn't support quad channel anyway. Here's my full spec list if it can help. ASRock B450M Pro4, Ryzen 7 2700x + Wraith Prism Cooler, 4x4GB Corsair Vengeance LPX DDR4 @ 3000mHz, Thermaltake SMART 500W and Gigabyte G1 Gaming 1070 Rev 1.0 Thank you for your help.

You're using a mix of Vcolor and Patriot NVMe drives, with some being downclocked and others at full speed. Your setup includes staggered configurations on the same board, which is fine according to the manual. Just make sure your workload matches the performance you expect from each drive type.

Could you clarify what you require beyond 16GB? I usually don’t need the 32GB setup most of the time.

The main reason is probably because I found someone selling the 3200mhz kit for cheap on the marketplace so honestly this is a good opportunity to future-proof my machine a little bit for the years to come. Also can I ask if you have to underclock and overclock the 2 pairs to the same speed or is there a particular reason for you to do so? Thanks.

they need to match the same timing and speed, which is why they’re running faster or slower than expected.

All the memory in the system must operate together at identical speeds and settings, which means your motherboard can't adjust them separately. You might be able to push your existing RAM up to 3200MHz, but if you install new modules, you'll need to lower their clock speed slightly. Make sure each 8GB module is on a different channel to avoid flex-mode behavior. Do you really want the additional memory?

Sure, that’s correct. Just go into the BIOS and select 3000 under the RAM speed dropdown.

It seems like you're sharing a quick message about a purchase. The price in Canadian dollars for a new RGB RAM kit caught your attention. Thanks for the clarification and support!
