Problem with newly added RAM

[pio123]

At first i bought 2 sticks of 4GB RAM and now, a couple of months later i bought another two to get 16GB. It seems that I got what I wanted, but the XMP profile doesn't seem to load on the new sticks, as they run at different frequencies and voltages.

Yes, all 4 sticks are the same model (G.Skill F3-17000CL9D-4GBXM) , and XMP has been loaded in BIOS.
Any ideas how to fix this?

CPU-Z is showing it running at 2128.4 pretty close to the XMP2134?

Everything looks good, if the system is stable you're ready to go!

Yep, you are fine, the slight discrepancy is no big deal, you could check for a BIOS upgrade that might align the data rate close, but it's nothing that will affect performance (keep in mind it's DDR (DOUBLE data rate) so data rate is 2 x freq of 1064.2 (2128.4)

Probable cause is most likely motherboard running fsb slightly slower than std.

What about the latency? You sure it won't slow the other sticks down or something?
I also tried changing the memory voltage in BIOS from auto to 1.650 but CPU-Z still showed the same thing.
Also, I want to point out that if CPU-Z on the 3rd screenshot shows the sticks in the order they are connected, something went pretty wrong. The old sticks were inserted into slots 2 & 4, not 3 & 4 like it appears to be.

The third screen is only showing the available programmed timings on the sticks they are all running according to the second screen.
