Again, SuperPi will tell you.

I know. I was wondering why he said that I should probably run 1866Mhz is all.

I made that question because you would get even better superpi results in 1N.
Not surprisingly better, just a tad better.

4 sticks at these speeds get a little rough on the memory controller.

for instance, I have 4 sticks of samsung green ram that are fine at 2666mhz 11-13-12-27-2n with 2 banks populated, any mix of sticks.

When I add 2 more sticks, I cannot get them a shade over 2133 at any voltage or timings, and no amount of tweaking has been able to help me. I currently only run 2 sticks of 4GB for the speeds, as this gives me the minimum FPS advantage, which leads to another 5~ fps ( talking 120fps~ in BF4 ) average.

edit: dont need 4 sticks to defeat superpi, and capacity can help in other applications up to a certain point.

Isn't 1.65v harsh intels memory controller? This I have no proof of, just what I read here a dozen times.

afaik, it was only for sandy bridge, even then I ran my memory at 1.72v on my 2500K.

Yea I know that, same happens with my motherboard. Motherboard manuals even refer to that, that only some slots can go to certain speeds. My can go up to 2400Mhz but only on the red slots I believe, the black ones are limited to 2133Mhz. Doesnt bother me cause I dont reach that speed.
On topic I honestly don't know which one is the better, the superpi run posted by the op wins in some and loses in others.

its pretty subjective. I know some will say lower timings, some will say higher clocks. I happen to think they both have their streangths.

Lower clocks can lead to lower voltages, where higher clocks usually require higher voltages. Not that ram uses alot of power, or creates alot of heat, but lower voltage will usually lead to longer lifespan.

I however dont care. If I break it, I had fun getting there.

Since I'm getting slightly better results at 2133Mhz 10-12-12-31 2n, I'll go ahead and leave it at that setting. Might as well get more for my $$$. I only paid about $90 after taxes for my 16GB of system memory so I'm more than happy considering the price has pretty much doubled since I bought it. I think I'll be fine until I upgrade to a motherboard that supports DDR4. Thanks for the info guys. thumb.gif
