New Vengeance ram still running at 1333mhz

post #1 of 8
Thread Starter 
I was running XMS3 ram and it was running at 1333mhz. I was told that the P67 sabertooth mobo is supposed to run DRAM at 1.5v and to get memory that is rated at 1600mhz at 1.5v. So i did. I thought. The part number for my ram is CMZ8GX3M2A1600C9. I know that with the XMS3 that is rated at 1600mhz but at 1.65v DRAM it is not good to run it at that voltage. It also overclocks the PC if I try to set it to run at 1600mhz in the BIOS. So doi still have to go into the mobo to set the memory speed to 1600? The last time I did it after words I started getting cold boot issues and I cleared the CMOS and it was fine again.

Any ideas?

Go into your bio's and manually set it to 1600 mhz. Then find the memory timing's and put, 9-9-9-24. Find Dram voltage and put 1.5v. Those are the default setting's for your memory so once you do that you should be ready to go

The only issue is teh default is 1.5v for DRAm and ASUS told me that is what it should be. They said 1.65 can be unstable. Several people said that this Vengeance ram will run at 1600 at 1.5v without oc'ing the system. I can go in and set it to run in XMP I guess or just set the memory like you said but If the DRAM goes to 1.65 then It may give me some issues.

Simply switch the CPU Overclock Profile to XMP and it will take care of the memory speed/timings/voltage for you and won't overclock your CPU at all. I'm running Corsair Vengeance 1866 memory that way on the Sabertooth with no problems.

OK I will try the XMP then and see how it goes. I wanted to get the Vengeance with the CL8 but they didnt have it. It is what Asus suggests in their manual as well. Oh well.

Corsair Vengeance memory is default at 1.5v 1600MHz Cas9 for his kit, not 1.65v. With 1.65v I have seen some of those kits hit 2GHz+

@OP

Just use XMP or overclock it yourself and set it to 1600MHz and change the timings. There is no need to touch the BCLK or CPU multi. You should be able to select 1600MHz and then just change the timings to the default 9-9-9-24

With disgusting timing's probably, that doesn't mean much unless they have hit those speeds with timing's lower then cas 9

Got it sorted it looks like. Set in XMP and it did the rest. Runs at 1600mhz at 1.5v which is great.
