I'm shopping for a DDR5 RAM kit from the same manufacturer and found two options with identical 5600 MT/s speed and CL36 timings: a 32GB kit made of two 16GB sticks for $540, and a 64GB kit made of two 32GB sticks for $400. I'm new to building PCs, so I'm confused about why the higher-capacity kit costs less. Could this be a pricing error, a compatibility issue, or something else I should check before buying?

At $400, the 64GB kit is cheap enough that I’d be cautious. It could be a pricing mistake, a clearance deal, an open-box or returned item, or a listing from a questionable seller. Make sure the listing clearly says it is a new, complete 2x32GB kit and check the return policy.
Also watch for marketplace listings where the headline price changes once you select the seller or add the item to your cart. Check who fulfills the order, whether the product is new, and whether the displayed price is still valid at checkout.
The 64GB kit may simply have been purchased by the store at a better wholesale price, or the two products may have different promotions and inventory costs. Hardware pricing can be surprisingly inconsistent. Before buying, confirm the exact model numbers, seller reputation, warranty, and that the price remains the same at checkout.
There is no general rule that 32GB must cost less than 64GB. Supply, sales, demand, and store mistakes can all produce an upside-down price. The important things are the actual specifications and compatibility with your motherboard—not just the capacity. If both kits are genuine and supported, the 64GB kit would be the better value.

That makes sense. I’ll compare the exact models and verify the final checkout price before ordering.
