[SOLVED] xmp only gets to 3466

[meno5150]

Im trying to get my xmp to work right. i can only getting it to 3466mhz with all 4 slots filled i cant get it up to 3600mhz. But i can get it up to 3600 with only 3 slots filled a1a2b2 but when all 4 are in i can only get up to 3466. anyone know why?

Having 4 sticks put more stress on the memory controller. You might not be able to get to 3600MHz. A 2x16GB RAM KIT would had no issue getting to 3600MHz.

Asrock probably uses daisy-chain topology for connecting the DIMM sockets in the motherboard layout. Daisy chain makes for better two-DIMM (or 4 DIMM when only 2 sockets are populated) overclocking but can seriously limit the overclocking potential when all 4 sockets are populated.

A point-to-point topology would be better for 4 DIMM arrays with all sockets populated but that results in worse overclocking potential when only 2 sockets are populated. So that's generally used on top-end boards where customers don't mind the expense of 4 DIMM's and more likely to need that much memory.
