Question CPU Game Boost Function and RAM Question

[Bauer24x]

im gonna keep this short as possible. Soo i got new ram cause my ram went bad. im running 3000mhz Corsair Vengeance Pro RGB. i decided to turn on XMP and its at 3000mhz. So in the bios it says 3000mhz but when i go to the corsair engine (ICUE) it says DRAM Frequency 1507mhz? it also says 1507 on other 3rd party software. So is this what i guess they would call something like double data date. in reality its 2x more then that? i saw it in this post? ill post it after my next question. This question is actually kinda more important? So i have game boost on which i doo it OC to 4.40ghz, but when i click the info icon it says game boost on = i7 8700k MAX 4.80ghz? So my question is why am i at only 4.40ghz in bios and i tried going in a game to see if it increases to see if it uses more or needs to use more ingame and it doesnt use beyond 4.40ghz. Is it possible its not going to 4.80 cause i have xmp support on? Please let me kno thanks

ddr mean double data rate as in 1507x2

Alright so that is the case. Soo i am at 3000mhz. Soo by anychance you kno why my cpu OC isnt at what it says?

As @rgd1101 already stated above - that is correct. DDR means double data rate, so the third party programs tend to show a 'single data rate' for example - meaning you can effectively double it to get your true speed.

In regards to the CPU - I suspect this is on all 4 cores? In which case it is normal as it will act (roughly) as follows:

1 core turbo = 4.7 MHz
2 core turbo = 4.6 MHz
3 core turbo = 4.5 MHz
4 core turbo = 4.4 MHz
5 core turbo = 4.4 MHz
6 core turbo = 4.3 MHz

Also this is assuming you're actually referring to turbo clock speed, not just plain OC.
OC is manually done, turbo is a kind of automatic OC set by the manufacturer but in reality are 2 generally different things as they are applied differently.
