| 1487297 | 2022-07-08 21:15:00 | I have upgraded my PC to an Asus Z170 board. It was necessary to upgrade the RAM to DDR4 so I got 3200Mhz. It seems that I am using only 1662Mhz. I am working in the dark here and cannot work out how to get the maximum of 3200Mhz. I have looked but am flummoxed. Could someone help me fix this please? |

| 1487298 | 2022-07-08 21:59:00 | rog.asus.com Short version; 1) No matter what speed your ram kit is rated for , stock speed for most DDR4 kits is 2133Mhz hence why unless you manualy OC your kit or enable XMP/DOCP profiles ( i would advise you to set speed and timings manually and not touch DOCP ) your ram will ran at stock speed ! Corsair iCue shows 1065Mhz because DDR stands for '' Double Data Rate'' so a kit running at 2133 is '' effectively '' running at half the rated speed ! 2) Now that you know the basics lets move to the next topic . Just because you bought a kit rated for 3600Mhz it doesn't mean that your processor will be able to run at this speed and that's especialy true for Ryzen ! Indeed Ryzen memory controller on 1000 and 2000 series ( wich is responsible for RAM speed ) is pretty sensitive when it comes to RAM speed , much better on 2000 series than 1000 series but still . In general you will have hard time to achieve 3600Mhz on Zen+ ( 2000 series ) on dual channel ( 2 memory sticks ) let alone on quad channel ( 4 memory sticks ) hence why you are experiencing those instability issues ! |

| 1487299 | 2022-07-08 22:12:00 | Thank you piroska. I had a feeling that was what was happening. My system is however intel with an i7 6700k processor. I have set the dram to XMP and the Dram speed is set at 3200Mhz. ASUS instructions point to XMP1 which does not appear in the BIOS of my motherboard. | Bryan (147) | ||
| 1487300 | 2022-07-08 22:15:00 | Reading on the ASUS forums, its stated The RAM speed issue with Z170-A is well documented Being an older board you may look at the BIOS version to check if there's a newer version that may ( or may not) help. |
