Hello

When I made my pc on Pcartpicker I got this message:
"The Kingston HyperX 8GB (2 x 4GB) DDR3-1866 Memory (KHX18C9T2K2/8X) operating voltage of 1.65V exceeds the Intel Haswell CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum."

Could someone please explain what this means in English and what it actually menas to the pc?
I am having some BSOD's for a long time, could this be a cause?

Atm I'm not OC but maybe in the future I will.

Thank you

EDIT: My memory actually runs at 666.5 (Dram freq) as shown in CPU-Z.

Spec for the Haswell CPUs is 1.5, running 1.65 is perfectly safe, though for 1866 I'd stick with 1.5, 1866 needing 1.65 is indicative of either weak sticks (shouldn't need 1.65) or that it's an old line of DRAM. 1.6-1.65 doesn't usually come into play till you hit 2133 and up. If wanting 1866 would look at the GSkill Ripjaws X or Snipers in 1.5

Hi, thanks for the answer! I bought the sticks about 1 year ago and I just replaced my GPU... Atm I'm not able to buy new RAM. So there is no problem with this issue and my pc will be fine?
I'm running this config for 2 years now and sometimes I'm having some BSOD's but then this is not the cause?

Thanks

Well I have not to be honest.. I'll install them soon but I think the problem was with my old GPU. Currently I'm on integrated graphics from my CPU and haven't had BSOD's so far...
