memfinder Posted February 10, 2012 Share Posted February 10, 2012 I've got an M4A88TD-M/USB 3 and a Dominator (2 x 4) 8GB CMP8GX3M2B1333C9. In my BIOS, the system is reading the DRAM frequency as 1067 MHz instead of 1333 MHz. How can I configure it correctly to where I can get to the advertised speed? I heard that with my particular RAM, you have to set it to 1.6 volts to get the right settings. All I need to know is how to set all of the settings in BIOS correctly.

Synthohol Posted February 10, 2012 Share Posted February 10, 2012 please post a screenshot of CPU-Z mem tab. Link to comment Share on other sites More sharing options...
memfinder Posted February 10, 2012 Author Share Posted February 10, 2012 Here is the screenshot you've requested. I did look at the timings in CPU-Z and it seems to me that with the AMD system the voltage would stay the same when I looked at the SPD tab under the JDEC columns. Does this give me all of the information I need in order to set the right timings in BIOS? Note that I'm not trying to overclock. Link to comment Share on other sites More sharing options...
Synthohol Posted February 10, 2012 Share Posted February 10, 2012 the spd info should be all you need. remember though set the command rate at 2t not 1 right now you are at standard default settings, any faster and you ARE overclocking. just a reminder :): since you dont want to overclock.

memfinder Posted February 10, 2012 Author Share Posted February 10, 2012 So, In my case the highest setting would be JDEC #4, since I don't have an Intel CPU? It's strange, the timings on the box and every where I've looked say 9-9-9-24 but these readings are coming out different. Shouldn't each module be operating at the DRAM frequency to equal a total of 1333 MHz? I'm not sure if this data is even accurate. Honestly, this is the first time I've ever tweaked RAM timings before. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 10, 2012 Corsair Employee Share Posted February 10, 2012 By default the memory is getting set to DDR1066 so that is why the timings are showing at 8-8-8-24 1T. I would go to BIOS setup and load setup defaults and set the memory Voltage to 1.6 Volts and set the memory frequency to DDR1333 and set Command Rate at 2T. Then check them with CPU-Z under the memory Tab to see what they are running at. Link to comment Share on other sites More sharing options...
memfinder Posted February 11, 2012 Author Share Posted February 11, 2012 In case you need to see this information, here it is. This is the SPD data I'm going by, before I even consider to change anything at all. I want to make completely sure that we're on the same page. The SPD reads 1.6 volts for XMP which I thought was only for Intel CPUs. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 13, 2012 Corsair Employee Share Posted February 13, 2012 DDR1066 is default for AMD systems you just need to set the tested settings manually. Link to comment Share on other sites More sharing options...
memfinder Posted February 14, 2012 Author Share Posted February 14, 2012 My motherboard in particular supports up to 1333 MHz before overclocking to the best of my knowledge. Are you saying I would be overclocking the RAM if I were to set it to that DRAM frequency? Say I was to enter exactly the information in JDEC column #4 of the SPD from CPU-Z, would that also be overclocking? If that's the case, I don't even want to touch these settings because I don't want to burn out my system. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 14, 2012 Corsair Employee Share Posted February 14, 2012 Not exactly, what I am saying that by default the MB and CPU will set the memory frequency to DDR1066 and yes you should just set the timings and frequency manually is all you have to do.
