Overclocking Fail on boot

[Guest]

Hey guys, sometimes when i boot up on my PC i get a overclocking failed! message but im not overclocking anything, im 99% sure its the ram because i change it back to 1866mhz and save and exit and it works until it happens again. It resets my ram to 1600mhz but i would like it at 1866 mhz. and ideas on a fix for this? PC list is on my signature

Thanks

What are your actual specs for the DRAM, i.e. brand and model #? If they're 1333 MHz sticks (as they look to be, based on your sig build) then you are overclocking them by running them at 1600 or 1866. Same goes for 1600. If they're actually rated at 1866 MHz, then they may not be getting the right voltage and/or you may need to apply a slight overclock to your CPU, as the chip's memory controller may not be getting enough juice to properly manage the DRAM at the higher speeds.

Try loading CPUID and post a screenshot of the SPD tab.

Is it just me, or did your DRAM speed in your sig change? Anyway, this note is from the Asus website: "Sandybridge processors are binned to run DDR3-1333 speeds at stock voltages (CAS 9). Higher operating frequencies are defined as overclocked, so voltage requirements and overall stability will vary from CPU to CPU. The same rule applies to Ivy Bridge processors, although the margin has been extended to DDR3-1600 at stock voltages for these CPUs. As such, unconditional stability at higher operating frequencies cannot be guaranteed and will vary between processor samples.

Were your sticks a matched set or is it a mixed set?

I updated my sig ahah. And they were a matching set straight from newegg

Try going in to your UEFI and under AI Tweaker/Digi+ Power Control look for VCCSA Load-line Calibration. If it's on Auto or Regular, set it to High. (You may need to adjust your VCCSA current capability and boot voltage also, but I'd wait to see affect of just load-line change.) Then set the DRAM freq that you want and save settings and exit to boot.

How does it run under the XMP profile? It might be easier to just run it at 2133MHz if those profiles work well.

Ill check my BIOS now, and its in xmp profile 1 which is 1866mhz should i just try it at 2133 before i change the VCCSA and such first?

I would try it first at the speed you want to run as the settings optimal for each speed might be different. Personally, if I had 2133 sticks, I'd be running it at 2133 but I assume you have a reason for wanting it at 1866.

I set it to XMP profile 2 which is 2133mhz so we shall see if that is the fix. If not i will return!

Thanks for your help in the meanwhile.

Hey, i just tried to turn the system on this morning and it would prompt me to enter bios like usual then go to a black screen and stay there. I went into bios and put ram at 1600 and its now fine i guess ill have to OC my CPU to get it at anything above 1600 mhz?

Looks like it - did you try bumping the VCCSA? You might have to bump the clock speed slightly, but I'd try adjusting just the memory controller first. If it won't allow you to do that and keep you inside the XMP profile, you may have to set the speed and timings manually but that's not hard - basically just copying the timings on the stick to the proper setting windows in BIOS.
