Question MOTHEBOARD B450M WITH 48GB RAM

[ventedtax0]

Hi everyone,

I have two sticks of RAM 2x8GB Corsair 3000mhz and I want to buy two more, but It will be 2x16GB 3200mhz. Do you think it will work? My motherboard is a gigabyte b450m ds3h with the lastest bios version.

Regards

No answer might and might not.
You really need to just buy a set in the amount you need.

When I work on my pc it reaches 16 GB RAM in use then I would like to add more ram, I could sell in the future the two sticks that I have now.

Best of luck. When you add the new 32GB to the old 16GB RAM, disable XMP in the BIOS at first to see if the system boots up with 48GB.

Don't be surprised if you cannot run 2 dissimiar pairs of RAM at the same XMP frequency as 2 sticks.

For a start they have different maximum XMP speeds of 3,000MT/s and 3,200MT/s.

Secondly, the CPU's IMC (Integrated Memory Controller) will have a harder task driving 4 DIMMs instead of 2.

I was wondering if I could put sticks 8-16-8-16, could it work with dual channel 3000mhz?

Buy a matched set of the amount you need and sell the old set.

No. If you want to try for 48GB, fit the RAM as 8+8 in A1, B1 and 16+16 in A2,B2 and see if it boots at stock JEDEC speed (2133 or 2400).

Invoking XMP might select 3000 or 3200MT/s, depending on which pair is read first in the BIOS.

If you get 3200, swap over the two pairs of DIMMs and try for 3000. You stand a better chance of running all four DIMMs at 3000 and not 3200. Even 3000 may be too fast for 4 DIMMs which place more load on the memory controllers.

There's absolutely no guarantee that any of this will work with mis-matched DIMMs, especially at XMP speeds.

Ideally you should buy two 32GB DIMMs for 64GB total. Running 4 DIMMs is often more difficult than 2 DIMMs, especially with XMP enabled.
