(Dark Hero VIII + Ryzen 5950x) Quad rank Ram Setup results in memory errors

Level 8

I'm using two f4-360016q-64gtznc kits.

I can use one kit in Ramslot 2 and 4 with positiv soc voltage offset of 0.1(1.18v) and dram voltage manually set to 1.37v. 

Testmem5 with extreme preset results in 0 errors in 3 cycles. When adding another kit into ram slot 1 and 3 i get like 8 errors in 3 cycles.

Is there anything I could adjust to get rid of the errors?

Hi @hanswurst31 

Please see the information here regarding combining memory kits.

Combining and mixing memory kits isn't supported by memory or motherboard vendors. If you combine memory kits, the overclocked settings in which the kit is validated for XMP/EXPO are no longer valid. Purchase a single kit validated for the density and frequency you are trying to run. This is because memory vendors bin and validate the memory kit in the density in which it is sold. Whether we combine a kit with the same part number, frequency, timings or voltage the advice remains the same.

my bad. It's one kit = 4x16

Assuming this one?

This doesn't appear to be on the motherboard memory QVL, however, GSKILL have validated it. This many ranks is challenging on X570. Try reducing frequency to 3200MT and select DOCP / XMP II
