Two identicle RAM with different chips?

Chiyawa · November 25, 2019

Hi everyone,

I bought two XPG D41 3200MHz 8GB RAM when I built my system, and all works as it should, although XMP profile couldn't get the speed right sometimes when I cold boot the system. I can manually set the DRAM clock to 3200MHz in my BIOS and this issue is gone, at least until a BIOS update resets everything.

And just recently, I got curious of my system and trying to get to know what my system has, so I went to my motherboard (Gigabyte Aorus X570 Pro WiFi) BIOS and inspect each components one by one, and to my surprise, the BIOS SPD reported that one of my XPG D41 uses Samsung chips while the other uses Hynix chips. Also, their manufacturing year is different. I was like, seriously? How could two identical RAM (at least the manufacturer name and model) uses different RAM chips?

So, what do you think? Am I being cheated?

If you didn't bought them as one package of two but as two separate sticks that could be possible.
If they came from the same package they should be the same and have sequential serial numbers.

Module manufacturers may change the chips used at any time without notice on otherwise the same marketing module. Normally if you buy two at the same time they should be the same, but it is not guaranteed 100% as in this case.
