RAM for Haswell build - is 2400MHz worth it? - Page 4

and even if you set it to 125blk 1600 is max on 100 it will be max on 125 no? I ask because I only use 125+ thanks to picky components

I think all 125blk does is give you more options for what speed to set the ram at.

I'm not sure that I understand your question. Are you asking if the max useable ram speed is 1600MHz for both 100MHz BCLK and 125MHz BCLK? If that's the question then no, the 125MHz BCLK would allow you to have a max useable ram speed of 2000MHz.

I have the GSKILL Trident X 2400mhz 2 x 8gb set and I really like them. I have been playing with my overclock and setting the memory to 1333mhz and I notice a definite difference in system responsiveness between 1333mhz and 2400mhz. I also notice smoother performance in BF 3, and I think my minimum framerates are higher as well. For those who like every last ounce of performance I recommend it.

If you get a chance, could you try running the RAM at 1600MHz and see how much of a difference there is from 1600MHz to 2400MHz? Also, what is your BCLK running at when you did these tests?

My theory is that your max usable RAM frequency is based off of your BCLK. So if it's set to 100MHz then you shouldn't notice much of a difference between 1600MHz and 2400MHz. However, you would notice a HUGE difference between 1333MHz and 1600MHz+.

Sure, I will try that and repost. My BCLK is at 100mhz.

I should mention though that I upgraded to 16gb of 2400mhz from 8gb of 1600mhz and noticed a definite difference in smoothness in Battlefield 3, and I'm pretty sure in terms of system responsiveness as well.

I will try it out with 1600mhz though as long as my motherboard will go along with it.

Alright, so if your BCLK is at 100 then comparing 1600 to 2400 would be sufficient.

Your motherboard shouldn't have a problem underclocking your RAM. I ran my 1600 RAM comfortably at 1333 and was able to push it up as far as 2166, but I saw a performance DROP when I went to 2166 so I dropped it back down to 1600 then OC'd my BCLK to push the RAM up to 1833... which is where I keep it at now.

The jump from 8GB to 16GB could have caused the improved smoothness and responsiveness even by itself. When I upgraded from 4GB to 16GB my render speed nearly doubled in Adobe After Effects. Both sets of RAM had the same 1600MHz timing.

that would be great!
