Combining RAM types? That’s a tricky situation.
Combining RAM types? That’s a tricky situation.
I'm using 32GB of Crucial Ballistix 3600 with a Ryzen 5 3600 running at 1800MHz. I'm considering adding more RAM after upgrading to a Ryzen 9 5950X. Crucial stopped selling performance RAM, and their current DDR4 "Pro" sticks only offer 3200MT with CL22. I want to keep the original clock speeds at 1800. I've been with Micron/Crucial for a long time, so I haven't focused much on other brands. Should I replace one 8GB pair with two 16GB pairs from another reliable brand? Or should I just purchase another brand's 2x32GB DDR4 3600 CL16? (The Crucial "Pro" 3200 2x32GB is about $100 on Amazon, but I prefer faster speeds and better timings.)
You can purchase additional RAM with Micron memory of the identical type, and it should function properly.
Combining RAM is quite tricky, and matching capacities adds another layer of difficulty. Even within identical model numbers, you might encounter kits that don't function well together, and compatibility issues become more likely when adjusting capacities. These are the same products as before, but without the XMP profiles included. If you need to input a specific profile manually, it should work fine. I’d likely choose another kit unless it’s extremely affordable.
I thought blending wouldn't be effective. The fact that the Crucial Pro 3200 shares components with the Ballistix 3600 is a positive—especially since it's currently on sale. G.SKILL Trident Z Neo 3600 seems promising based on specs, but it costs 50% more than the Crucial. Which brands appeal to you?
I focus on price rather than brand reputation. For clarity, a standard DDR4 kit typically includes four main components: the IC, the PCB, the SPD, and occasionally a heat spreader. The IC is produced by several major manufacturers such as Samsung, Micron, or SK Hynix, though the final selection depends on the specific supplier. The PCB is often manufactured in-house, with companies like Corsair and G.Skill being well-known for this process, but many use identical boards from the same factory. The SPD contains the data about the memory module and is produced in various locations, while the programming details are handled internally. The heat spreaders tend to vary between kits, making them a key factor if you're aiming for manual overclocking. Unless you need something unique, the differences usually come down to the heat spreader and the binning process.
Are there any online repositories listing component usage patterns similar to past monitor panel designs? Regarding your system, you're using a Ryzen 7 5800X3D with HyperX 3200 CL16 RAM—do you set both FCLK and MCLK to 1800, or is AMD adjusting them differently?
No, that's not true. The RAM speed has a noticeable impact. With the 5900X I had 1600 MHz, and with the x3d it's similar.
It's not feasible to operate both clock speeds simultaneously. The MCLK must match either a 1:1 or 1:2 relationship with the memory clock. You can't adjust arbitrary values like FCLK. For example, if targeting 3200MT/s, set FCLK at 1600MHz. Check the label for exact details; it will indicate the IC model, such as ".M16FE1" or ".M8FB1". A value of 16 means dual rank, while 8 indicates single rank. You can use this to estimate IC density and identify the revision. Typically, you should look for Micron 16Gb Rev. B on these components.
Confirming the details: the RAM displays Ballistix 3200, FCLK is 1800, and MCLK is set to 1800 in BIOS. Voltage and other settings weren't changed. BIOS shows both clocks at 1800 and the system runs smoothly. The CPUID test likely verified the 3600 MHz speed.
