Combining RAM from various suppliers doesn't maintain consistent performance.
Combining RAM from various suppliers doesn't maintain consistent performance.
Hi, my Hynix 2666MhZ 8 GB Single Channel Rank1 RAM was already installed in my ROG Strix G15. After upgrading, I used HyperX Impact 8GB 2 666MHz DDR4 CL15 SODIMM, which supports both 2666Mhz and 2400Mhz. However, it seems the RAM is limited to 2400Mhz instead of its full capability. It’s confusing and I don’t get why there’s a cap.
I don't understand why it's limited in your setup, since I'm currently using these on my desktop: 2x8GB G.Skill TridentZ 3600 cl16 2x8GB Crucial Ballistix 3600 cl16. All four sticks function perfectly together with XMP enabled. It seems possible that mobile chips might be the issue.
It's unusual that each RAM stick operates at 2666MHZ. Given the chipset's support for that speed, it seems reasonable they should function together at that frequency.
