I'm setting up an AM5 gaming system to play at 1440p and dabble in Deep Learning for image generation and local LLMs. Here's the lowdown on my build: I'm going with a Ryzen 5 7600X processor, an RTX 5070 graphic card, and I'm eyeing DDR5 6000 MHz CL36 RAM, likely from Corsair Vengeance. My motherboard is the Gigabyte B650M Gaming X WIFI6, but it only has two RAM slots, which is raising some concerns. With the current price hike for DDR5, I'm torn on the best RAM option:
1. **Option 1:** Start with 1x 16 GB now, and add another 16 GB later (maxing out at 32 GB).
- Approx cost: ~18,999 INR (~211 USD)
- Will be single-channel initially.
2. **Option 2:** Go for a 2x 16 GB kit right away (32 GB in dual-channel).
- Approx cost: ~40,700 INR (~453 USD)
- Dual-channel from the get-go but still capped at 32 GB.
3. **Option 3:** Pick 1x 32 GB now, add another later (up to 64 GB possible).
- Approx cost: ~31,500 INR (~351 USD)
- Starts single-channel but allows an upgrade to 64 GB later.
I have a few key questions:
A. Is 16 GB in single-channel enough for a setup like this, or will it bottleneck performance for gaming and light DL?
B. If 32 GB is the practical minimum, is dual-channel 2x 16 GB significantly better than starting with 1x 32 GB and adding more later?
C. Is it a mistake to choose a motherboard with only 2 RAM slots? Should I consider one with 4 slots?

If you have the option for a dual CCD setup with 48-64 GB RAM and at least 16 GB VRAM, that might be worthwhile. Just get the best you can afford right now—don’t stress about the RAM configuration too much at this stage.
I suggest starting with 1x 16 GB RAM for now and upgrading later to 32 GB. You'll want a motherboard with four slots for better future upgrades. By the way, you had a small slip regarding the motherboard; the Gigabyte B550M is AM4 and won’t work with your AM5 setup. Just grab the B650M instead!
Thanks for the suggestion, and I appreciate you pointing out the motherboard mistake!
Regarding your questions, for A: While 16 GB is on the low side now, it should be fine for most games but might bottleneck in some cases—especially if the game demands more RAM. For B: Dual-channel 2x 16 GB is generally better for performance in gaming and workloads compared to single-channel, but the difference can depend on the game. For C: Avoid using four sticks of DDR5 if possible; they often default to lower speeds. If you need higher capacity, it's better to add more RAM sticks later.
Yeah, I’ve seen that boards tend to run poorly with four RAM sticks at higher speeds. It's a hassle.
You can expect some performance drops in gaming with single-channel RAM, but how much it affects you varies by game. Some are more CPU-intensive and show bigger gains with dual-channel. Your ML workloads likely rely more on GPU VRAM; generally, most tested setups don’t show a huge impact. Check out these links for more details on performance differences.
Yeah, ML tasks are going to need VRAM more. The RTX 5070 you have is good, but moving to a 5070 Ti could be worth it for future-proofing, even if it’s a bit pricier.
Are you suggesting the X3D CPUs? And are your RAM and GPU VRAM recommendations geared towards deep learning needs?
