"Cache frequency doesn't matter"

Are you high? It indeed does matter. This "core is king" talk is extremely silly if what you are after is consistent framerates, without extreme variation and low fps valleys. Basically your advice is encouraging high benchmark scores but wildly differing framerates in CPU bound titles. I came from a haswell 4.8ghz where the uncore was essentially garbage 2400 cas 10 uncore 4.2ghz to a skylake 4.6ghz (4.7ghz refuses to be stable) with an uncore of 4.6 and 3333 cas 15 ram. I gave up 200mhz on the cores and some latency, but guess what, even in single threaded performance its still superior, and its blatantly more consistent in its delivery of framerate in crisis 3. Cache frequency absolutely matters, you just need quality ram for it to make any real difference. I was disappointed, I got my CPU delidded and bought if from a binning service to hit 4.7. Indeed it passes aida 64 at 4.7 by 4.7 for 5 hours, but the instruction set isn't being hammered like in crisis 3. Yes I know its spelled differently, that's autocorrect for you. At the end of the day I cant be that upset because it still has a clearly far superior IPC thanks to its memory system. I asked for the memory controller be binned as well, so at least I have a 1:1 ratio for efficiency.

Well mileage might vary a bit but with an Asus Z170-K altering the cache ratio makes things slower. Not huge amounts but on a very intensive set of Database Calculations it is a fraction of a percent slower using a 1:1 than simply leaving things on Auto.

Care to show any data to support these claims?

Hhhmmm, I read where Cache freq. wasn't as important on Skylake and I do run a lower Cache freq. on my skylake setup. From all the tests I have ran and games played now if cache freq. meant more or as much as it used to it hides itself well.

Yes, cache freq if you're dropping it by GHz could see slightly lower performance but last I toyed with it it took a 1.5GHz slow down in cache freq to essentially equal a 100MHz lower core clock.

I also am using a very low fclk with minor to no impact, my fclk is only 566MHz and I have yet to notice any true performance hit even to min fps.

Core does seem to be king from my experience on skylake.

Ya...

I've been messing with this platform since it came out. I have three 6600 k's and two 6700 k's. Some were delidded and some weren't... running anywhere from stock to 4.9 giggles. The only thing I ever really notice with cache is in certain benchmarks. As far as just turning on my machine and gaming or the other various things I do.

I haven't ever really noticed a difference.

Then again maybe it's just because I don't ever leave a build together long enough to notice (lol).

make sure at least C1E is enabled and if you want very low voltage (eg, parked cores) enable all the highest c-states. Why not just use adaptive voltgae?

I got the results, I believe that you are seeking...

Everything on Auto, except for the multiplier @ 46!
I don't get it? So whats the point in setting the voltage manualy when you can just use Auto and it works?
And no, it was not Auto I was after.. I wanted the voltage to be Adaptive so it goes down while not under load. But still wanted the voltage of 1.38v as thats the minimum I can use.

Guide says set the voltage to w/e needed for an stable overclock, which I did, 1.38v (vcore in HWiNFO = 1.376v minimum & 1.392v maximum).
But.. 1.376v is a little high for idle tbh, so I wanted it to be "adaptive". So I tried that, didnt work (worked with 4670K I had).

So what should I do to get an "adaptive" voltage? Setting it on Auto seems wrong..
And as it doesnt seem to work when using Adaptive voltage instead of Manual, I don't know what to do. I only get the "IRQL_Less_Or_Not_Equal" BSOD when booting with adaptive voltage.

Please provide evidence of cache frequency having an effect on frame times. Even in CPU bound scenarios, I haven't noticed cache frequency making any difference.

Ok I'm going to try that. Can HWInfo show that I'm actually entering that parker cores states? I think I've seen my HWInfo show a minimum of 0v before but I assumed it was a bug because when I checked my log, it only occurred at 1 instance

Regarding c-states, my MSI board seems confusing compared to ASUS boards posted here. Should have poured in a couple more hours on research on mobos before buying. I think mine only allows one C-states at a time Here's my mobo settings.

Would selecting C8 be enough or just put it on auto?

That's actually my end goal but I'm having problems on it and I'm having a hard time getting some help. I posted my issue on this thread a couple of pages back. Maybe you can assist.

I'm just a beginner in overlooking and followed this guide. I got a stable 4.3 @ 1.25 on my 6600k on override settings with all power savings stuff off. Now I'm trying to take advantage of EIST, CStates and the likes, they are fine when on load but I noticed that when coming off from a long IDLE state then doing some light / medium task, I would sometimes get a random x101 BSOD

select c7 or c8 c-state as the c-state limit. Also remember, parked cores is not something you want to happen if you are a hardcore gamer. For normal 2D work, parking cores is not that big of a deal. C-states are a bit misleading.. the voltage drop is only because of core idle/park, the active core(s) will still receive the override voltage you set in bios. either use offset or adaptive. and with adaptive, c-states are best left disabled. thumb.gif

not sure I can help much with that MSI bios, maybe others here can chime in on Adaptive voltage with MSI.
