Higher uncore = faster memory?

[LiveOrDie]

im just been testing a few things and i get better memory performance running a higher uncore than a lower one? i still have to run LinX to see if its stable but any one know why this would be?

I assume you are running the same memory speed with different Uncore clocks, yes ?

"This means that if you run 1600MHz memory in your Core i7 system you will get the added benefit of a faster memory controller and L3 cache. At 1600MHz both the memory controller and L3 cache operate at 3.20GHz and at 1866MHz they run at an impressive 3.74GHz. So, without changing anything other than the memory speed in the BIOS you can change the frequency of the memory controller and the L3 cache by using performance memory. Here is a quick table to show you what the Uncore Clock Speed (memory controller and L3 cache frequency) with the memory speeds that I will be benchmarking today"

I didn't know the L3 cache speed varied with the uncore clocks, to be frank, but if this is true then this will be the most likely reason for your performance increase (Although the memory controller frequency can't hurt either).

L3 cache is designed for the Memory subsystem in machines these days for latency compensation.

im running at 3.6Ghz cpu clock ratio at 18x my memorys on 1067Mhz/2:8 so it stays at 1600Mhz, cpu host at 200 and uncore on 18x, but i had my uncore on 16x before and i used everest to test and i get faster read/right running it on 18x

As does L1 cache and L2 cache. I am not unfamiliar with the concept of cache memory, I just did not realize the Uncore speed affects the speed of the L3 cache on i7 CPUs (Although it does make sense).

here i just screenshot both the 1st is at 16x and the 2nd at 18x see what i mean

the uncore is all on the core that doesnt run on the cpu clock and are clocked separated.
something along them lines. i think
