1600 memory only reads at 1333?

[safstar]

My Corsair Vengeance Version 8.16 (8GB 2x4GB) says it runs at 1600MHz but I think the problem is with my GigaByte 970A-DS3 only reading it at 1333MHz (I confirmed this in BIOS) I can not over clock the RAM because after I boot it says "due to a recent over clock the system cannot operate..." It then goes back to 1333MHz...Recently after installing BF3 PC crashes ( First kept crashing in WIN8 so I thought it was a WIN8 error so I installed WIN7 Ultimate instead...Installed twice that is...) Something about a blue screen that says MEMORY_MANAGMENT...I did not have this problem before BF3...

It seems that running on 4GBS of RAM seems to work. So that is why I think the problem is with my MOBO

thanks.

Check the BIOS settings in your mobo and see if you can manually change the memory to 1600.

I have...But it says "due a recent overclock the system cannot boot..."

Have you made any other changes to your BIOS? Reset your mobo to default settings and start over.

So the board will only support a memory frequency of 1333Mhz limited by the chipset, or the cpu bus speed memory controller.
If you changed the settings DDR3 at 1600 Mhz should be set 800Mhz memory each way =1600Mhz.
Also check for the speed that the Cas settings are right Ie: 15:15:15 24 rated on the memory modules and the settings match it in the bios settings.

My board is almost the same as yours, mines a D3 not a DS , I had the exact same problem, adjust your cas timings as per the label on the ram or the packet it came in and voila full speed

How exactly does one reset their BIOS? I cannot seem to find this option...

Edit...Sorry the retard (me) found it

Are these in the M.I.T? If so I cannot find them.

Ok guys don't reply any more based on speeds... I got it to 1600MHz but could you tell me the second part of my question? Why I can only use 4GB's of RAM.

Have you got 32 bit windows or 64bit, 32 bit restricted to a little less then 4gb, you need a 64 bit version to use all of your ram, same goes for pretty much all operating systems, plus if your graphic card can be using up some of your system ram, I have a Radeon HD6670 that will take up to 2.8gb of system ram if you have enough to spare

no I got 64...now I cant even get to BIOS...or a splash screen just a loud beep sound... already took CMOS out...didn't help

Uninstall BF3, then re-install OS, then set it to XMP.

AMD doesn't use XMP.

When you set the RAM to 1600MHz with all 8 GB, do you set the timings and voltage to what it says on the package?

1. on AMD board, it is called D.O.C.P as XMP in Intel board, just go find it if your memory support this function.
2. you need also higher your cpu ratio to get desired memory frequency, please try.
