[SOLVED] Help with upgrading to 64GB RAM - Add or replace?

[Cantholdanylonger]

I'm planning to upgrade my RAM to 64GB and I'm unsure whether I should:
Sell my current kit (2×16GB) and buy a new 2×32GB kit
or
Add another 2×16GB kit with the same brand and model.

Here are my current specs:
Motherboard: ASRock B550M Pro4
CPU: AMD Ryzen 5 5600
Current RAM: ADATA XPG Gammix DDR4 3200MHz 2×16GB
(I’ve overclocked it to 3600MHz CL16, fully stable)

If I add another identical 2×16GB kit:
Will my current overclock still be stable or maybe lossing performance because using 4x16?

I mainly use my PC for gaming and multitasking. Stability is important, but I’d like to keep as much performance as possible.
Appreciate any advice on whether 4×16GB or 2×32GB would be better for performance and compatibility with Ryzen 5000.

If you want to add to your existing ram kit, you should look for the exact same ram kit. I'm not familiar with Adata ram kits but Corsair tends to source memory IC's from multiple vendors which is why they have a PCB revision number. People thought they were investing in the same kit of ram(since they look identical aesthetically) but underneath the OC's were different and the cause of stability or ram issues.

Personally, I don't know if you would be able to run high capacity ram with two sticks on two slots at those speeds but in general, two sticks are always better than 4 as that puts less stress on the integrated memory controller.

Try and flash the BIOS to the latest BIOS version, then pick up a 2x32GB DDR4-3200MHz ram kit and give it a go. Speaking of purchasing, how much are you seeing a 2x32GB ram kit for? Prices for DDR4 are on par with DDR5. In fact the speeds of DDR4 vs DDR5 are greatly different.

Noted!

i live in indonesia and the prices for DDR4 are not par with DDR5,
ddr5 2x32gb is 184$ (Gskill Flare X5 Black 6000 MT/s cl 36-36-36-96)
ddr4 2x32gb is 124$ (Team Delta RGB 3600mhz cl18).
And for the ddr4 2x16gb is 54$ (ADATA XPG Gammix 3200mhz cl16)

the price diffrent between 64gb and the 32gb is a lot so that why im asking if i can cut the cost

If you decide to fit another pair of 16GB DIMMs to save money, set the BIOS to the JEDEC default (typically 2133 or 2400MT/s) before adding the RAM. The system might not start at 3600MT/s with four DIMMs installed.

Due to additional loading on the IMCs, you might have to restrict your memory overclock to 3000 or 3200MT/s with 4 DIMMs. If you run games, RAM speed is important. If your main interest is video editing, slower RAM speeds will not reduce performance much on AMD.

Run MemTest86 to check stability at each XMP/EXPO/DOCP setting.

As @Lutfij says, two 32GB DIMMs is the better choice for 64GB total.

I successfully upgraded a 3800X from 32GB to 64GB with two pairs of Corsair Vengeance DIMMs (for a total of 4 x 16GB), but I'm running them at 3000MT/s which is the maximum speed programmed into SPD.

okey thx, i think im gonna save the money for 2x32gb
