Followup picture, all four cores under load:

3.6ghz as predicted.

 

I think this without a doubt proves that turbo scales depending on how many cores it thinks is under load.

Do you still have your C-States manually set to C7, with the other Power Saving options enabled? Or did you go completely back to defaults?

I didn't think that was in dispute, it definitely sets the multiplier based on how many active cores there are. It's been that way since Sandy at least.

As I understand it, BLCK is different than 125 167 200 BLCK "Strap" (which only affect 3-4 things like ratio memory and cache)

I can get 111 BLCK, and it's very sweet place to be, just the computer is poppin, lively. The problem is game freezes, hard freezes, and I have to power off to reboot. As I understand it, still frame freezes (no BSOD), is, a Memory problem, umm maybe too tight of timings set, Or I guess maybe too much OC of MHz on the memory. When I set to 111 BLCK the 1600 memory is OC'd to 1776 O_o so I guess it's fine idk

I relaxed my timings for tomorrow, I don't have time to test now, saved another profile, I have to sleep, but Game Still Screen freezes (Hard) are a memory problem are they not? If I play on another setting with a 105 BLCK then no freezes, AS LONG AS, my timings are set to 9-10-9-30...if I try to 9-9-9-27 or the like, then the freezes start happening again, but on this High of a BLCK which ups the memory even more from 1680 @ 105 BLCK to 1776 @ 111 BLCK then I guess I accordingly, Must relax the timings even more from 9-10-9-30 to idk?? what? tomorrow I'll be going from 10-10-10-30..Do you guys have any other timings for such a higher memory MHz? I know 1866 is a standard that, depending on the RAM, may even have 10-11-10- (what?) What's a standard timing for higher RAM to set my OC'd 1600 RAM at?

I never knew that. Well, them two people were disagreeing with me. :thumb:

Why does that affect the results? All settings to default, except C states which is at C7. I highly doubt C7 is causing the difference and it's annoying to have to go back and redo all the pictures for default C states. I don't even know the default.

I'm pretty sure that we were discussing whether or not the 4670k would boost up to 4.6ghz on default settings....Every 4670k owner should know that their CPU goes to 3.8ghz, I don't believe that fact was ever being doubted....

That question was sheer curiosity, when I'm looking at data, it's helpful to have all of the facts - or at least as many as I can possibly have....thumb.gif

If I am reading correctly, Forceman agrees with my conclusions, saying that it should have been known all along.

 

The intel specification webpage lists 3.8ghz as "max turbo frequency" which leaves room for lower turbos.

Their turbo boost specifications webpage lists:

 

 

Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests the highest processor performance state (P0).

The maximum frequency of Intel Turbo Boost Technology 2.0 is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment.

Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:

  • Number of active cores
  • Estimated current consumption
  • Estimated power consumption
  • Processor temperature

This can be found here:  http://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-technology.html?wapkw=turbo+boost

Are you guys mixing up 3.6 and 4.6? I think there was a typo somewhere (4.6 written instead of 3.6) and you might have gotten your wires crossed.

Freeze will be due to cache voltage too low most probably, with memory instability somewhat less likely (yet still very possible). When you adjust bclk, you're moving core clock, cache clock, and memory clock. Please don't use bclk of 111 rofl - youre in no-mans land with that. Use a higher multiplier with lower bclk instead. The formula is:

Frequency * bclk * strap (adjust decimal points as necessary)


The higher you attempt to clock memory, the looser the timings. No set timings apply for a given frequency; it's specific to the DIMMs themselves. If you bought lower-end memory, chances are you won't be able to clock it much higher even with loser timings and more voltage - memory is not a cpu, not all DIMMs are on the same playing field and different clocks aren't a matter of chance. The only exception I can think of for low clocked memory which can reach high clocks is Samsung Green

http://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors#cite_note-turbo2-3

 

Lists 4670k with Turbo of: 2/3/4/4. With 3.4 stock.

 

4 core active = 3.4 +2. = 3.6

3 core active = 3.4 + 3 =3.7

2 core active = 3.4 + 4 =3.8

1 Core active = 3.4 + 4  =3.8

 

The number I add is from their chart on Wikipedia. Each number is one bin or 100mhz of OC.

The thing I'm saying is, 3.8 on perfect conditions which won't be replicated unless you tweak core affinity, and 3.8 is max and can be as low as 3.6, which I had no idea was the case.
 
Yay, I learn many things about Haswell today. Many things.
