Purchasing RAM for the 5800X3D
Purchasing RAM for the 5800X3D
It offers a solid improvement in speed, but I'm cautious about suggesting 4x8GB modules. I've noticed this issue often with various memory configurations—like mixing different chips from different manufacturers on the same stick. For reference, memory makers usually choose the lowest-cost IC to meet performance targets, so you might end up with a mix of Samsung C dies and Hynix DJR dies on the same module. Combining them at rated speeds is challenging. The best options are either 4x8GB kits or modules that guarantee specific chips, such as Crucial Ballistix 8GB sticks (Micron Rev. E) or Hynix DJR modules with high-frequency, stable timings. If you really want consistency, opt for a kit with a known, single-rank chip. Trying to track the exact die in a kit is usually not possible unless you buy used Corsair products, which often include decodable version numbers. While some people hesitate about used RAM, Corsair’s listings usually reveal the specific chips used. Generally, Ballistix offers good value, though it doesn’t match the top-tier performance of Samsung B die modules—unless you need more than 8GB.
Ballistix performs well even at a lower price, though a solid B die would likely improve results. The 3800MHz CL16-16-16-34 setup with minor timing adjustments could work, while the 3800MHz 14-14-14-21 configuration needs tighter timing around 1.5-1.6V based on kit quality. Both options are decent, but Ballistix is recommended for their reliable overclocking RAM and consistent performance.
It depends on your perspective. I’d prefer 80% performance for $125 instead of paying another $100 for the remaining 20%. I’m not claiming B-die is bad, but I don’t believe the costs are justified.
The X3D stands out by using less RAM compared to other 5000 series CPUs. I’d opt for an affordable 3600 CL18 with 32GB. To boost performance, consider a PBO tuner paired with the curve optimizer, and choose a motherboard that allows BCLK overclocking for extra gains.
The way your initial message is phrased seems to imply a negative view of B die, which is where my concern lies. I understand that B die only makes sense in the context of overclocking, as the timing benefits are most apparent then. If you're just using XMP, the difference isn't significant. Still, B die isn't as costly as you think—with a 16GB Ballistix kit you'd pay around $65, while the cheapest option costs about $80. For an extra $15 to overclock, it could be worthwhile.
It was that video that motivated me to purchase my second 3200c14 unit. I feel completely free to choose any speed I like. The range is wide—3200, 3600, 3800 c14,15,16, flat, mixed, tight subs with higher voltage, regular subs with lower voltage. It offers a lot of flexibility. With my 5600X, I can run both kits simultaneously, but not at the same time, depending on the speed bin I prefer. I’m hoping DDR5 will feature its own B-Die type chip.
