I recently got a replacement DDR4 RAM kit from Corsair and I'm trying to figure out the chip brand and die type it uses. I know CPU-Z can tell me the manufacturer of the DRAM chips, but how can I find out the specific die type? Do I need to take off the heat spreader and risk voiding my warranty? Is there any software that can help me with this information? Also, would contacting Corsair with my RAM's serial number help?

If you want to know exactly what die you have, you might need to look at the version number printed on the RAM modules. Corsair's different versions indicate the die type: V3.XX is Micron, V4.XX is Samsung, and V5.XX is Hynix. If you're hesitant to remove the heat spreaders, you can always try reaching out to Corsair again and see if they can assist you with the serial number.
You can make educated guesses based on your RAM's specs like speed and timings. For instance, if your RAM is rated at 3200MHz CL14 or 3600MHz CL16, it’s likely using Samsung B-die.

You could use Thaiphoon Burner to check the die type, but sometimes it can be unreliable. I've had mixed results with my own Corsair Vengeance kit. Just remember, even if it says ‘B-die’, it doesn't exclusively mean Samsung; other brands can have similar designs.
