Arimurad :
There are four slots two blue two white, I can mix the two have a corsairs an the old ram, but more than two just causes the computer to beep...
Okay, now I get your problem. Right-off it's NOT a good idea to mix-match RAM because you get problems quite often like you're describing. The worst mixes include Frequency, CAS Timings, Voltage, Density...different IC's.
Now if you can post links (**) to both of your kits I'll give you Manual Settings that might work, but in all honesty it's best that ALL of the RAM is the exact same (1st) kit or ... (2nd) kits.
This will require you to boot to the BIOS with (1) kit, make the BIOS settings, install the second kit, and thoroughly test with Memtest86+ for 4 full passes i.e. overnight.
Example:
DDR3-1600 9-9-9-24-2N @ 1.60v ; DDR3-1333 9-9-9-24-1N @ 1.50v JEDEC 667MHz
DDR3-1333 9-9-9-27-1N @ 1.50v
=======================
DDR3-1333 9-9-9-
27-1N @ 1.50v ; worst of each kit @ DDR3-1333
(**) - My preference are the 'SPD' CPU-z info for both kits; see below:

Just to save some time, let's ass-u-me the mix is DDR3-1333 9-9-9-
27-1N @ 1.50v which is fairly common, so I'm guessing here:
1. Boot into the BIOS with (1) kit
2. BIOS settings:
Load Optimized Defaults
MB Intelligent Tweaker(M.I.T.) /Enter
System Memory Multiplier -> 13.33 ; 100MHz*13.33 = DDR3-1333
DRAM Timing Selectable -> Quick ; sets ALL of the RAM the same
Channel A/B Timing Settings /Enter
CAS Latency Time -> 9
tRCD -> 9
tRP -> 9
tRAS -> 27
-
Command Rate (CMD) -> 1 ; 2 if problems
-
QPI/Vtt Voltage -> 1.10v ; +0.10v with 16GB is recommended and below the max safe 1.20v
DRAM Voltage -> 1.55v ; +0.05v if needed and I recommend that you use 1.55v with a mix
Save & Exit = Yes
3. Add the second kit; each kit MUST be in the same colored DIMM Slots:
CPU: | Kit 1 | Kit2 | Kit 1 | Kit 2|
