Wont default to 1866mhz


Recommended Posts



Just bought a few bits and built myself a system. When I was setting up i noticed i can not set the ram to its default speed of 1866mhz i could only set it to 1600mhz XMP without blue screening before windows boot


things i have tried is setting XMP to profile1 SPD multi to auto, no success tried SPDx12 i think which put it at 1866mhz and still blue screens. then found that only the 10xSPD = 1600Mhz works


I have tried setting it manually 9-9-9-24/1.66volts cos it wont give you the option of 1.65volts


tried setting my cpu to default and set the spd to 12 which = 1600mhz then tried x14spd = 1866mhz multi and then blue screens, i have tried it several ways like QPI/vtt, 1.415 and 1.65 instead of auto on both. SPD 1600Mhz = ok and then 1866Mhz blue screens



Is there anything else i may of missed that might be causing a conflict or have not setup right to get it to sit at default 1866mhz




thanks Mack

That may be because of the CPU you have and with that MB you will need to get the latest Beta BIOS and then just load setup defaults and enable XMP should be all you need to do and with only one set of modules.
