XMP doesn't work

[sman_steel]

Hey, I got a new pc today and afterbuilding i enconter an issue with the XMP profile, I have Corsair LPX vengeance 3600 CL20, A B450 aorus Elite and an AMD 3600. Are they any known issues about this configuration or any tips for me, I am currnetly running at DDR4 base clock : 2133 MHz.

Keep in mind on most motherboards 2666MHz is considered overclocking so mileage may vary, just because a kit of RAM is rated for 3000MHz does not mean it will be stable. 

 

If you cannot enable XMP/DOCP you can attempt to manually adjust DRAM speed and voltage. OR, this can also be done if you want to try and squeeze even more performance out of your RAM.

 

I for example have OC'd my 3200MHz RAM to 3466MHz, at 1.3750V (DRAM voltage) and tightened my timings. ]

 

Okay so go into Bios and disable XMP, (excuse the Asus terminology, it is the only bios I know well), then go to advanced settings, then AI tweaker. 

 

From there you are going to want to adjust your memory frequency, I generally recommend single incremental jumps, so from 3000MHz you would go to 3066Mhz, then go down to DRAM Voltage and set it to 1.3500V. Save and exit Bios. As mentioned earlier if you get caught it a boot loop and the settings reset to default you know the memory OC was not stable. 

 

If stable enough to post into Windows then run a quick stress test, I recommend Cinebench R15 (runs faster than R20) and if stable restart and post boot into Bios. Also, keep in mind stable in a quick stress test is not the same as stable during a gaming session. Windows stop codes related to memory will let you know that your memory OC is not stable.

 

If you hit instability along the way start upping the DRAM voltage by increments of 0.010V (so 1.360V, 1.370V, 1.380V... etc) until stable, I would not recommend exceeding 1.450V though. 

 

So once stable at 3066MHz you can push further, 3133MHz, 3200MHz, 3266MHz, 3333MHz, and so forth, each time testing stability, possibly adjusting voltage and this is how you OC your memory, eventually you will hit a wall.

 

For me this 'wall' was 3466MHz at 1.3750V, but at 3533MHz even at 1.450V I was not stable. As said before mileage may vary. Even at 3033MHz you may not be stable at all.

for AMD its Called D.O.C.P in bios instead of XMP, try turning DOCP on

Chabax, in mine that's call XMP, i think that's an aorus choice. thanks anyway

An Thanks TheDailyProcrastinator, I'll see that, but my motherboard was sold as

Memory : 

• 4 x DIMM, max. 64 Go DDR4 3600(O.C.) / 3466(O.C.) / 3200(O.C.) / 2933 / 2666 / 2400 / 2133 MHz, non-ECC, un-buffered memory

does it mean that i just have to copy all the timings frequency and voltage from my XMP to do it manually ?
