Difference in DRAM manufacturing ID across memory modules
Difference in DRAM manufacturing ID across memory modules
I recently purchased two additional Corsair Vengeance PRO SL sticks. The previous set matched exactly, except for the color—this one is black. Both sets are 2x8GB, PC4-25600, 3200MHz, with timings 16-20-20-38. I also disabled XMP before installing the new units. I checked the BIOS to ensure consistency, but observed a change: the new RAM lists Samsung as the DRAM MFG ID, while the older RAM shows Micron. Curious if this could cause any problems or if it’s just a labeling difference.
Basically, it just means that Corsair switched from using Micron DRAM chips to Samsung DRAM chips for this model. There is some chance it could cause a problem, but as long as it boots with XMP settings and you don't plan on overclocking them beyond that, it should be fine.
It’s unlikely to be reliable and may cause kernel power issues. I’ve encountered this situation multiple times when mixing RAM on a Ryzen processor. The RAM model is E3200C16, but it’s difficult to locate a compatible motherboard in the support listings.
the motherboard checks timings that both agree, so issues won’t arise. you’ve already installed and opened it, so you’ll discover this before the 30-day return period ends. if it crashes with a blue screen or similar, there’s nothing you can do to fix it. just return it or sell it and get the full 32gb version.
