AM5 configuration with 64GB RAM is stable and capable of running at full speed.
I'm currently using two G.Skill Trident Z5 NEO sticks (AMD Expo DDR5 6000 CL36-36-36-96). I'm thinking about adding four for extra capacity, aiming for around 80% utilization. I remember someone named Wendel from lvl1tech talking about problems with four RAM sticks. Anyone have heard of that? P.S. I'm using a GIGABYTE B650 AORUS PRO AX motherboard with a 7700X.
You won't be able to run 4 sticks at DDR 6000. The best you can achieve with four sticks is DDR 4800. https://www.gigabyte.com/Motherboard/B65...ort-memsup ASUS (or I don't know the gig ID). They're releasing a HALCYON MB with just two slots for advanced OC, claiming it supports DDR 6600 on AMD5. However, they're using shorter traces and only two slots. The evolution of memory controllers—double channel versus quad, single-sided versus double-sided, single bank versus double bank—is incredibly complex to track. In short, for the quickest memory upgrades on AMD5, using two sticks is recommended. Micron is also coming with 48GB per stick, which could increase to 96GB in two slots later. But I haven't seen any updates from the AMD BIOS for AMD5 yet, so to be safe. With more than 32GB regularly used, it's advisable to use ECC memory and quad-channel or higher thread ripper systems. It's tricky to separate the performance levels between pro, consumer, and general hardware. It's hard to tell people to buy a high-end chip and then suggest limiting memory access for optimal results. That's where we stand now.
Intel and memory controllers on CPUs/chipsets combine to restrict DDR6 features, as it includes an extra chip on the sticks. Notably, AMD generally offers better flexibility with more options for unlimited uses, while some CPUs and boards support ECC memory, but Intel typically limits this to server and workstation models. x670 chipsets are mentioned. AMD AM5 supports Ryzen 7000 processors and DDR5 with ECC memory, though it also supports DDR4. The 5-year warranty is highlighted for the AMD AM5 socket.
It seems your BIOS now includes ECC support, which is great. You can opt for full 128 GB if it fits your needs and performance goals. Industry standards suggest ECC memory is beneficial for heavy workloads, though it may slightly affect gaming performance. Here are some interesting points to consider.
From a positive angle, lowering the price to 4800 gives you a $100 discount on the upgrade. It's interesting that 5200 is the most affordable option available. DDR5 5200 (PC5 41600) offers timing of 36-36-36-83 CAS latency, 1.25V voltage. The page from Newegg lists it at a reasonable price and notes that ECC DDR5 4800 isn't widely offered yet. Still, your current setup should work smoothly together at that speed.
