PC freez on 1600 mhz not 1333

[iemand]

Hi,

My motherboard set my ram speeds automatic on 1333 mhz but when i change it to 1600
my pc freezes after start up in few mins.Why ?

PC specs.

H87 g43 gaming (my mobo supports 1600 mhz)

i5 4670

Corsair Vengeance 8 GB DIMM DDR3-1600 CL 9

does it continue to freeze on startup even after several reboot cycles?

Are you sure the right timings are being loaded?

i need to push the power button to shut down my pc. When i start it back its freez agian after 4 or 5 mins sometimes after 1 min sometimes after 10 min

the timings are good 9-9-9-24

Edit (does the latency make a differince ? my mobo supports the corsair latency with cl 10 my one is the cl 9 latency )

check the bios settings for the ram profiles that may be conflicting with your static setting of 1600mhz.

reboot and check again after each change.

i checked all are ok.

Have you enabled XMP in your BIOS and did you select the 1600 XMP profile and save it?

 

[iemand]

no i set it to manual but does it make differince?

 

[COLGeek]

If your settings are not quite right, then yes, it can make a difference. Give it a shot. Good luck!

Are the timings difference from 1333 mhz vs 1600 mhz? so yes can some say me that?

 

[COLGeek]

Yes, the timings at 1333 and 1600 will be different. If you are just changing the 1333 setting itself manually to 1600 and not adjusting the other settings, then that could explain the problem.

However, for this model of Corsair memory, the XMP profile settings for both 1333 and 1600 appears to be the same:

Is this the exact same memory you are using?

How can i see what the timings are for 1600 ?


Im using this memory model CMZ8GX3M2A1600C9R

Go into BIOS in the advanced or tweaker page, enable XMP and select profile 1, should set the freq to 1600 and the base timings to 9-9-9-24 and DRAM voltage to 1.5, give that a try, if no joy, try updating the BIOS is an update is available - else try raising the DRAM voltage to 1.55
