Attempting to increase RAM speed
Attempting to increase RAM speed
Does the spd tab on cpu-Z display identical specifications when slot 4 is selected?
With a second identical kit purchased, could the RAM sticks have been swapped?
Matching RAM is essential for proper function.
Even matching part numbers and batch codes might not guarantee the best fit.
The voltage requirements for 1333 and 1600 are identical at 1.5v.
Begin testing with a single stick to check if XMP is activated.
The motherboard manual should indicate which slot to use with just one stick.
Repeat this process for each stick individually.
If none activate as a single unit, there may be an issue with your motherboard or BIOS.
If one stick works, try the others until you find a match.
If problems persist, reach out to g.skil support.
I should note that the performance gap between 1333 and 1600 is relatively small (excluding IGPU).
Here’s an older reference:

Individual testing. All silicon is unique, just like paint or carpet has different dye lots even if supposedly the exact same color, there's always some varience. With 1600, 9-9-9-24 was generally decent, I've seen timings as low as 7-8-7-20 or so. That's why 1333 and 1600 didn't differ much, the 1333 could drop as low as 6-7-7-18 etc. The tighter timings making up for the slightly slower speeds.
Both sticks display clocks that are slightly off, but I'm not sure if this matters.
The ram is not matched.
Internally, they may not be compatible.
Ram needs to be bought in a matched kit.
They are probably defaulting to the base 1333 speed.
you would not notice any performance improvement running at 1600 speed.
But if that bothers you, buy a matched 2 x 8gb 1600 speed kit.
You could also contact g.skil support.
Ram has a lifetime warranty.
They may choose to fix the issue for you.
But since neither stick is defective, prepare to be disappointed.
