Die density difference

[Despacitus]

I added two more 8 GB ram sticks to my current build and I bought the exact same pair of my current vengeance 16 GB 3200 mhz cl-16. But when I tried to put them all together the system started to boot loop and when it got actually to boot it automatically disabled the DOCP profile in the bios and started running on a frequency of 2133 mhz.

When looking more into it I found out that it had a different die density that the previous one (8 GB for the new, 4 GB for the old one, both are B-die).

So is there anyway that I can fix this issue? or I should replace the new ones?

Be curious to see the reported SPD/XMP data for the two modules. Do you have screenshots available either from SPD tab of CPU-Z or alternatively Thaiphoon Burner?

 

I don't know about density in that regard but I'm wondering if this is more generally a case of increased loading. Out of interest, does the new kit by itself work at the higher speed? What's the CPU/mobo you're using?

Forgot to say, if it is a loading problem, usually it can be worked around by dropping the ram frequency a bit. After setting DOCP in bios, manually reduce it to 2933 or 2800.

Did you clear CMOS before trying to add sticks and enable XMP?
