I'm planning to build a PC in the next couple of months using a 7800X3D processor, and I'm currently faced with a RAM dilemma. I found a great deal on a Kingston FURY 32GB DDR5 6000MT RAM module for about 172€ (including tax). While 32GB is more than enough for my needs right now, I'm considering my options.
1. Should I just go ahead and build my PC with this single stick?
2. Would it be better to sell it and buy a 2x16GB configuration on the second-hand market?
3. I could purchase a 16GB module of the same type for around 110€, allowing me to have 32GB + 16GB.
4. As a joke, should I sell a kidney to buy another 32GB stick?
I'm curious about whether there's a significant performance hit using a single stick. If it's minimal (let's say under 7%), I'm okay with that for now. Also, how sensitive is the CPU to the RAM setup I'm considering? I'll pair this with my existing 4070 Super, but I'm unsure how much that matters.

The general difference between single channel and dual channel RAM can be around 40%, with dual channel giving you double the throughput. It might not matter much if you're not aiming for high bandwidth, but it could impact gaming performance noticeably.
For now, I’d recommend using the single 32GB module. Prices should stabilize, and if you really need more later, you can try to find an identical stick to pair with it.
Does that mean I wouldn't notice a massive performance dip in the short term if I go with just one? Seems risky to hunt for a better deal on two sticks if it's not essential.
Avoid using a single channel setup, especially for gaming. The performance difference can be significant, even if the memory speed isn't the highest.
Is that really true for DDR5? I thought it was better at optimizing single sticks. Do we have any solid numbers on what 'significant' really means?
Most experts suggest going with two sticks over one for consistency. DDR5 is better than previous generations, but mixing RAM isn't ideal and could lead to issues. It’s really about what games or applications you’re running, as some handle it better than others.
Deciding to sell the 32GB module for a 2x16GB setup seems like a solid plan. That way, you’ll have a better chance at improved performance down the line.
You mentioned this was true for DDR4; how does it hold up for DDR5? Are the improvements in newer tech lessening the impact?
