X299 Extreme4 and Corsair Veng. RGB Pro 3600 Issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi Team.

I have observed a strange behavior with my new System. When I start to overclock the memory with only one little setting (for ex. 1 timing 1 step lower or raising the clock to 3733) then the system fails in memtest64 right after some minutes. There is no other overclocking active.

If the memory is set up with the standard XMP Profile all works fine.
The memory should  allow some little overclocking.
Its the Rev. 4.31 with the Samsung B-Die's.

I have replaced the whole memory: same
Mainboard replaced: same

Config:
Asrock X299 Extreme4
Intel I9-9920X
32GB Corsair Vengeance RGB Pro 3600MHz (4x8)
Seasonic Focus Plus 850W Gold

Has anyone a idea?

regards
Maik

	I don't have the RGB variant but my Corsair Vengeance LPX 3600 kit absolutely will not go past 3600 no matter what I do. Timings, voltage, nothing will make it stable. My kit is also B-Die and I have tested it on 5 different systems now all with the exact same results. I suspect Corsair pushes their RAM XMP profiles to the bleeding edge and there is little room left to get more out of them.

	Thanks for the feedback. I was 1 second away to replace my CPU at last possible part because i have no other system for testing.

	Glad I could provide some info for you It's typically only the lower tier RAM kits that can be pushed significantly past their rated XMP. The higher end models tend to be binned to within 50mhz or so, particularly with older model kits manufactured before yields improved.
