I recently started building a gaming PC from scratch and got a deal on a Corsair Vengeance LPX 32GB kit (2x16GB, DDR4, 3600MHz, C18). Now, I've come across an identical kit for free. Should I run all four sticks together? Will they all work at 3600MHz? Has anyone else tried this with the same specs? Here are my specs:
- CPU: AMD Ryzen 7 5700X (3.4GHz, Turbo 4.6GHz, 32MB Cache)
- Motherboard: ASUS TUF Gaming B550M-Plus (mATX, Black)
- GPU: ASUS Dual RX 9060 XT (16GB GDDR6)

If you're using your PC for gaming and light content creation, 64GB might be handy down the road. However, get the single kit working first before attempting to add the second. If it complicates things, I'd lean towards selling the extra set.
Mixing RAM kits can be a risky move and sometimes causes boot failures. I’d suggest testing it to see if it works initially, and if you find it doesn't, consider letting it go. It doesn’t hurt to have extra capacity, but make sure it collaborates well with your setup first.
Honestly, I’d sell the extra RAM. 64GB is a bit overkill unless you're multitasking heavily or doing memory-intensive work like video editing. If you try them out and find they don’t work well together at 3600MHz, it’s probably not worth the hassle.
For gaming purposes, you probably won't see much difference with 64GB of RAM. Most games don’t even utilize more than 32GB effectively. You might be better off just selling the extra kit instead of adding it all together.
Running four sticks should theoretically work, and they might be able to reach 3600MHz, but it really depends on your luck with the silicon lottery. I'd suggest setting the memory speeds manually after trying them out. Many people run setups with 64GB at those speeds without issues, but if the system requires slower speeds, selling might be the way to go.
