Clevo Z170 with QTJ1 - compatible memory speeds?

[grisevg]

Got QTJ1 working on my P775DM3 with "ME_Disabled" dsanke bios.

But the issue is that it won't post even with a single 2666Mhz 18CL stick, only 2400Mhz stick.

I've seen people saying that QTJ1 supports up to 2666Mhz, some were saying 3000Mhz. On reddit one user claims that the ones with the lid on can do up to 3600Mhz.

 

Other folks with mutant cpus - can you share memory speed and timings tweaking advice?

Ram can clock a lot higher if you populate all slots on the channel. With a 9900K I can do 2933 with 2 modules, but with 4 I can do 3466.

 

With that said, only being able to do 2400 sounds low. It sounds like you're using very old DDR4 sticks. Something newer rated for 3200 will clock much better. If the 3200 can't boot at defaults, you can boot with the 2400 stick, set say 2933, then switch the sticks and the 2933 override will stay in place despite the stick change.
