As a rule of thumb non-rgb rams overclock better than rgb ones.
In general I like your ram, unfortunately it's not the rams fault this time, it's the motherboard. Well I can't just blame motherboard alone it could be 80% Mobo 20%CPU fault.
I had a similar ram than your Corsair LPX only with 100 mhz more, 4500 19-19-19. Unfortunately it didn't do 4500 but I could run it at 4400 CL 17-18-18 on Gene so in my case it was the CPU that didn't allow to achieve 4500 Mhz, the IMC on it.
Next time I would advise you to check the motherboards supported RAM list first, before buying ram. The big flashy sign on the box 4400+ is quite a bit misleading.
P.S. You can try to return the RAM and get one that is supported by your motherboard. You will save some money too probably, as the 4400 I assume isn't cheap.
i dont know what u mean by supported ram list ..
the motherboard says support DDR4 4400mhz ..
so i went and typed that in, and that ram poped up , thats how it went down literally ..
here is the ram i have
what do the timings mean
When you google your motherboard : Maximus XI Hero
You will get a link to Asus web page, top right corner is button "SUPPORT"
When you open that press "CPU / Memory Support"
Next "Memory /Device Support"
and open :
That's all the ram that is supported by the motherboard
Pay attendion to the last colums - 1/2/4 Dimms
As you can see that highest speed rams are only supported in 4 DIMM mode
P.S. Hope that clear things up, ask away if you have more questions.
P.S.S. This is default memory profile :
SPD Latency 15-15-15-36
SPD Speed 2133MHz
SPD Voltage 1.2V
What your memory will run without applying manual or xmp overclock
