Trident Z RGB 16GB (2x8GB) DDR4-4000MHz CL17 Not able to boot at 4000Hz

[Brunotx]

Hi,

I'm having a problem with my RAM (Trident Z RGB 16GB (2x8GB) DDR4-4000MHz CL17).

I had a previous kit (same ref) that was working perfectly with XMP enabled and speed at 4000MHz....

Due to the fact that those RAMs were delivered with the box already open I sent them for an RMA and the shop gave me another kit, this time, brand new...

The problem is that with this new kit, when I enable XMP to 4000MHz about 5/10sec after booting on W10 I get a BSOD...

I reduced the speed to 3800MHz and everything is working as it should....

Motherboard: Gigabyte Z490 Aorus Master
CPU: i9 10900k

Any help?

Regards.
Bruno.

Have you tried increasing DRAM Voltage and/or VCCSA Voltage to see if that can improve stability. Test each module individually to see if both have the same maximum results.

Are you using the latest BIOS?

Hi,

I updated my BIOS to lates but the problem still occurs...

Testing both RAMs individually W10 didn't BSOD...

I ran MEMtest on Both RAMs individually and the software gives me some errors.



Both at stock voltages with XMP activated.

Tested both RAMs with 3800MHz for over 3 hours an dno problems...

Any idea?

I suggest your CPU would be more stable at DDR4-2933 with tighter timing

You think it's a CPU problem?

the CPU contains the memory controller so the CPU can be the limiting factor for running high speeds.

Upping the voltage of the memory controller can help (not sure what its called on intel as i always used AMD)
