I'll just stop talking now ;-; I'll keep studying before I post again <_>
DDR5 memory connections differ from DDR4 in terms of contacts and pins. To maintain compatibility with the same number of slots, you'd need additional contacts or modify existing ones on the CPU socket. From an electrical standpoint, designing motherboards that support DDR5 is significantly more challenging due to the need for multiple signal layers to ensure proper insulation and high-frequency performance. Even if some pins could be reused, existing boards would struggle with stability, limiting DDR5 support to lower frequencies or requiring costly upgrades. The increased complexity also raises BIOS development demands, making it more practical to stick with DDR4 on AM4 and introduce DDR5 only on AM5.
Infinity fabric tops out around AM4 CPUs at about 1900 MHz. If you're very lucky you might hit 2000, which could allow RAM speeds up to 4000, though such chips are rare. The fabric matches RAM speed directly; if you don't keep them in sync (out of sync), performance drops. The ideal range is around 3733 MHz and 1866 MHz, with most chips fitting this. With some adjustments, 3800 and 1900 become achievable. I recommend a 3200 C14 b-die kit and overclock to 3800, or a Ballistix kit of 3600 C16 with an OC to 3800. There are many copy/paste settings available online for these builds.
Is 3200MHz sufficient? Will it keep up with future needs? Can I still use 4600MHz? Or should I move to a 5000-series? The 3600XT is quite special and performs well. I really enjoy the 4600MHz kits because they let me overclock to DDR5 speeds and delay the need for another upgrade.
You're still able to use 4600 Mhz DDR4, though you might notice a slight boost by setting it between 3700-3800 Mhz and reducing CL timings. That way, you could save money and opt for 3200-3600 Mhz instead. At 3600-3800 Mhz, performance stays balanced (one tick from infinity fabric, one from memory). However, keeping it at 4600 would shift that balance, possibly lowering performance in certain situations.
Sorry offended you, my intention was simply to collect more details ;-; I think I’ll stop now.
This model costs $100 for a 4600MHz chipset. It seems affordable enough for the price. I might go with 16GB and later expand to a 32GB setup if needed.
It wasn't intended to seem confrontational. I wanted to find out why the 1200 board was promoted for DDR5.
I mentioned in general that the post wasn't about you. Most folks tend to mess things up by inserting DDR5 sticks into DDR4 slots and other similar mistakes. But actually, if you're curious, a 4600 Mhz rating is seen as factory overclocking or approved by the stick manufacturers. These small memory chips come from companies like Samsung, Hynix, and Micron. They benchmark them at speeds such as 2666 Mhz, 3000 Mhz, and 3600 Mhz, categorizing them based on performance. Companies like Corsair or Kingston purchase thousands of these chips, promising they work at higher speeds like 3200 Mhz and increased voltages with more relaxed timing. Out of millions of chips, perhaps a fraction—say 10k—can handle the 4600 Mhz while operating at higher voltages and looser timings. The manufacturers then embed an XMP profile into each stick, allowing the BIOS to recognize and apply those settings. For most compatibility needs, the sticks also keep standard profiles, covering frequencies like 2666 Mhz, 3200 Mhz, and 3600 Mhz, plus tighter timings. If the motherboard can't support such high speeds, the BIOS will search the available profiles and choose the closest match. If no suitable profile exists, it defaults to a built-in setting for common speeds like 2133 Mhz or 2400 Mhz, requiring manual adjustment.
