hey man whats up. I have that memory but the 16gb version.
Here are a few things you can do:
first of all profile 2 is for 2400mhz, its for sandy or other platforms, profile 1 is what you need. If it isn't stable then do this.
Download the latest BIOS, go down the to bottom of advanced memory settings. Change to quick adjustment, not expert(you have to do this to change the setting), find Data Read(and write) Slew Rate, change both to 2 if that doesn't work set 3.
Okay then if that doesn't work your CPU will need to increase VTT voltage or IMC voltage, so try set VTT to 1.15 and IMC to 1.145. If that doesn't work then try 1.200 on VTT and 1.195 on IMC. Don't set 1.4v or 1.9, be carefule. You want to be 5mv lower than VTT on the IMC voltage for the voltage to stick.
now if that doesn't work then it might be an issue with XMP, try these settings:
you can try those timings, also make sure your memory is in the green slots.
if you set 1.65v it should do 1.65v if vdram isn't working then flash your BIOS again, then power down(unplug the PSU from the board) and then clear the CMOS and remove the battery. On the new BIOSes a full power down is required to avoid all issues with stuff like voltage not working.2666 dominator plat c10 are samsung, they can take upto 1.85v on air or even higher like 1.9v, but they don't scale much over 1.8v. For 24.7 stay under 1.75, they don't get very hot eitherEdited by Sin0822 - 12/27/12 at 5:01pm
