We have 4.8/4.8 vs 4.8/3.8, here the core did not change.

By holding down the margin of error, I mean to say that, if I tested 4.8/4.8 vs 4.8/4.7, the results would be somewhat dubious because the margin of error could very well overshadow genuine decreases in performance. That's the main reason why I tested 4.8/4.8 vs 4.8/3.8. If it had occurred to me to test that benchmark that is very sensitive to cache frequency, I would have entertained the idea of testing 4.8 vs 4.7 cache for just that test, however academic I feel the test is.

Did a little quick testing while watching KC / Toronto. wink.gif
Impact of cache is where you would expect... image editing, game physics etc.

Nice and the effect on ram amplifies the more/bigger blocks of data moved around... but I fear you waste your time bud. cheers.gif

I notice no real differnce in anything with a cache overclock.


I will not sacrifice voltage for extra cache.

What I do is as said in OP. Find my stable CPU voltage say 4.7 1@1.35v, then set my memory OC (I found that running 1T needed a voltage bump of approx 0.1v) so 1.36v, then I bring cache up until its unstable, so say 4.6 will bsod then I just step back to 4.5. I could increase voltage of course to raise cache higher but its just not worth it. To be honest its not even worth it for me to run 1t over 2t but i like running at 1 command ! biggrin.gif


I find intel XTU memory test very good at finding unstable cache quickly. I would pass hours in AIDA but fail within the first hour at intel XTU.

^^ the XTU test is real good!
Did you run only the AID64 cache test, or have more than that module's box checked?

Hi Skylake overclockers,

What is your CPU Power Package reading using HWInfo?

I got 65W on max load using the x264 loop test posted in 1st page.

I thought 6600K max tdp is 95W? Did i got a golden sample? thumb.gif

Yesterday I tried to change my manual voltage to adaptive and it went OK when I test prime and x264 but crash in game all the time... Anyone know the reason for that ?

Gigabyte UD5

in manual I set my bios to 1.395 with LLC high( 1.410 on idle with multimeter, and 1.423 on load prime 1344k) its great no crash nothing

in adaptive without LLC ( it hit 1.55V with LLC on with adaptive to NORMALI cannot set the base voltage the motherboard it give me a randon one ( random cause sometime its 1.280 other time its 1.3)
so I add the adaptive to +.015 to pass the prime test , giving me 1.423V on the multimeter, and x264 giving me a lower vcore of 1.39 something. Both pass for a while but game ( arma 3) crash all the time after 10 min

I dont really want to raise the vcore again because of the number I got while prime but look like different load require different voltage, is there a way to make the cpu ask more vcore for "game load" it piss me off that prime is ok and x264 too but not game

Im back to manual voltage waiting to find a solution for that
