Gear 1 and Gear 2 on Alder Lake

Hey Guys, im having some weird issues with the ram on Intel 12th gen.

 

Ive just noticed that my Ram is running in Auto mode on Gear 2. After having heard that Gear 1 is preferrable, i tried switching to that, wasnt a good idea apperantly. After this the system just kept crashing, even in the bios screen.

Is my System faulty or is this normal behavior?

 

Specs:

CPU: Intel 12700k

Mainboard: GIGABYTE Z690 UD DDR4

RAM: 32 GB DDR 4 Trident Z 3600MHz 19-20-20-40

GPU: RTX 3080

 

I am really lost on this one, maybe one of you knows whats happenning here....

 

 

Thanks!

For me, Gear 2 also.  Haven't figured out yet,, what do the gears mean.

But my 3600Mhz RAM runs Gear 2 a tad above 4200Mhz (17-21-21-40 2T). So mant voltages and timings/settings in my MSI Z690 BIOS it's overwhelming.

I edit my posts more often than not

Gear 2 means the memory controller runs at half the frequency of the memory. Worsens performance for stability that Gear 1 wouldnt allow.

Gear 1 = the memory controller matches the frequency of your RAM. 

Gear 2 = the frequency of the memory controller is cut in half compared to your RAM. 

 

Gear 1 will have lower latency than gear 2.

Gear 2 typically allows for higher memory frequency than gear 1, and thus higher bandwidth. 

 

Gear 1 is better if your memory and CPU can run at it together. If they can't run in gear 1 then you can either go with gear 2, or you can try tweaking you voltages to try and get it stable. If they doesn't help then you have to choose between the best bandwidth and the best latency. Whichever is best for you depends on the workload. 

Chanses are it doesn't matter that much.
