Maximus XI Formula memory wont go over 3400MHz

[Pesari]

Hi, any suggestion how to get my g.skill trident z rgb 2x8gb 4000MHz go more than 3400MHz?

I have tried xmp profiles, manually tweak timings and voltages. Anything over 3400MHz and my computer boots to safe mode and back to bios. Pc tries about 3-4 times, couple of seconds and then shut down and safe mode.

I did have same problem with my HyperX Predator memory 4000MHz. Anything over 3400MHz is no go.

I have lates bios. Motherboard supports those memory*

I have tried bios at default and then xmp and with oc, but nothing changes.

Corsair RM1000x

Custom loop*

Im out of ideas.*

Did not know that only 2 dimms can be problem. I have had always 4 dimm slot mobo and used only 2 of them. But those times i did have only 3200MHz kits and different mobo.

Well i dont need more than 16gb memory and *another 355e for memory kit is not woth it.

I have tried with different slots and different voltages. And both xmp 1 and 2. Tweak mode 2 is something that i have not tried yet.

Is it possible to cause same problem if i put too much voltage for vccio or vccsa?*

Tuning VCCSA / VCCIO may help. You may want to try the Tweak Modes first, though. Most users favor populating all DIMM slots, which is favored by the T-Top trace layout. This doesn't mean the kit won't run at 4K, but tuning can often be needed.

Hi,

did you manage to achieve higher frequencies? I can't get over 3200MHz with the same hardware. No matter what I try, I get bluescreens or can't even load into Windows when going higher than 3200.

Thanks in advance.

Try A2-B2 slots combination. I had this issue when inserted A1-B1 combination
