Title: Problem with A75-D3H and Corsair Vengance CMZ8GX3M2A1600C9 8GB 1600 RAM
Post by: johuflo on March 08, 2012, 04:55:45 pm

I have the  A75-D3H with the APU 3870k and 8gb of 1600 mhz corsair ram (2 modules), the problem is i cant get those rams work totally stable at 1600mhz. firts with the F1 BIOS it woudnt even boot with 1600mhz no matter what voltage i used then i updated the BIOS to the F4 and with the new RAM profiles optios it boots with 1600mhz and it adjust the voltage to 1.6v, it runs stable most of the time but when i try to play a game it crashes or the system give me BSOD. At 1333mhz it runs flawlessly all the time with games and everything.


So i need to know if this is a board issue or what can i do to make it work at 1600mhz.  ???

Hi and welcome.

Well the memory you have should work at 1.5v but may have to increase the voltage a little to overclock it to 1600mhz. I would suspect the memory is faulty. Try running Memtest86+ exactly as below.


I would suggest that you download and run the latest version of  Memtest86+ to check your RAM first.

Memtest86+        http://www.memtest.org/

Insert one stick of memory in slot 1 and run Memtest on it for at least 10 complete loops/cycles and if there are no errors then swap it over with the next one and continue untill you have checked all  modules.
 
If you have any errors the module is faulty.

If you have any faulty modules you will have to return the whole kit as they are matched.

Post back when you have done that with the results.

It also depends on what kit you got they go from 1.35 to 1.65. Some you have to OC to get to the 1600 so it would be 1.65, If you have a kit that calls for 1.5 then you need to do as mantis says and run memtest.

Different Motherboard but i run 16 gigs at 1600 at 1.5 but they also will go to 1866 and higher levels if i put voltage at 1.65

This kit is set to run at 1.5v default.
