Dram voltage during the transition from 1600mhz to 1866mhz on MSI A68HM motherboard
Dram voltage during the transition from 1600mhz to 1866mhz on MSI A68HM motherboard
I have an MSI A68HM Grenade motherboard equipped with two G.SKILL Sniper Series sticks (2 x 4gb, 1866mhz). Upon first boot, the DRAM speed was configured at 1600mhz. After some research, I discovered I could modify the DRAM speed using XMP, even though my processor is AMD. I chose the initial XMP profile which adjusted the DRAM frequency to 1866mhz. I’m uncertain about the correct settings for voltage and timings — both are set to "Auto." When the frequency was increased to 1866, the voltage remained unchanged. Is this typical behavior?
I’m fine with the system functioning but a bit concerned because I’m not very experienced with overclocking. Any advice would be greatly appreciated!
Thank you!
XMP is an Intel innovation, for years many AMD manufacturers avoided paying licensing costs and opted to develop their own solutions (Asus created DOCP, GB introduced EOCP), while AMD released AMP itself—each of which interprets the XMP profile from the DRAM and then modifies the BIOS to apply the adjustments. More AMD boards are now embracing the genuine XMP technology.
All systems operate smoothly XMP adjusts timing and voltage when needed
All is well, XMP adjusts settings and voltages as needed.
Appreciate your reply! I’m still puzzled about how it functions with my AMD APU, but I understand now.

XMP is an Intel technology, for many years most AMD motherboard manufacturers avoided paying licensing fees to use it and instead opted to develop their own solutions (Asus created DOCP, GB developed EOCP), while AMD itself introduced AMP. All of these approaches allow the XMP profile to read from the DRAM and then modify the BIOS settings accordingly. More AMD boards are now adopting the genuine XMP technology.
Thank you for the clear details! This explanation was much clearer than anything I've encountered. Regarding the DRAM voltages and timings, does XMP automatically adjust them? I just need to confirm the DRAM voltage is correctly configured.
Thanks!
To verify the free app CPU-Z, examine the memory section to identify what processes are active. Although XMP is set to 'automatic' for data rate, timing, and voltage, it must be properly programmed through the BIOS to fully apply the XMP profile (it involves more than just base settings, including secondary timings and Command Rate).
It would default to 1.5v, the standard voltage. If it remains there, you're in good shape; just ensure it doesn't rise above 1.5 and you can manually adjust it if needed. You didn't specify the exact kit, but I don't remember any snipers using 1.6v at 1866.
It would default to 1.5v, which is the standard voltage. If it remains there and has risen above 1.5, you can attempt to lower it manually and check stability. You didn't specify the exact kit, but I don't remember any snipers using 1.6v at 1866. Thanks for clarifying!
