Memory Overclock not working?

[Kolden]

Okay so i have overclocked my Intel I5 6600k to 4.5 @ 1.325v and ram is set in XMP to 3000 which is the base speed for my Corsair vengeance Ram @ 16Gigs 

When i run aida65 or realbench neither one will show a clock on the memory more than 1500 (im new to overclocking could that be splitting the speed between the 2 sticks?)

can it actually run each stick @ 3000mhz? the cpu clock is showing just fine running 4.5 stable 100% load for hours @ 50c using an NIC5 Tower cooler. 

please let me know if you have any solutions or can explain something im missing. also if im running 4.5ghz stable @ 50c under full load is it safe to assume i can go higher? i saw linus only OC his 6600k to 4.7, is it worth it to push further?

1500mhz x2 = 3000 mhz, that's how double data rate works

As Morgan said above, it's DDR RAM so the speed you are seeing gets doubled. Your OC is working fine

Sounds like you're fine. I can't remember about AIDA64, but I know for a fact that CPU-Z reports the double data rate-specific clock speed instead of the data transfer signal frequency which is what the marketed 3000MHz is. For DDR, the clockspeed is half of the data transfer speed.
