When it comes to pure performance, I think it depends on you and what you want and/or need.  For me, I wouldn't benefit enough from the performance gained by upgrading to Ivy Bridge, but other people might.  It really depends.

 

From what I've read, clock-for-clock, a 3570K is noticeably a little faster and more powerful than a 2500K, but when a person is only concerned about the clock speed number, a 3570K would be disappointing because it tops out on air at around 4.5 GHz to 4.6 GHz.  However, again, clock-for-clock, the 3570K is a little faster.  So a 3570K at 4.4 or 4.5 GHz is like a 2500K at 4.7 or 4.8 GHz.  Going further, clock-for-clock and voltage-for-voltage, Ivy Bridge's temps are higher than Sandy Bridge's.  So the temps for Ivy Bridge at 4.4 or 4.5 GHz with whatever the voltage would be for that are higher than the temps for Sandy Bridge at 4.4 or 4.5 GHz with whatever voltage would be for that.  However, again, and one last time:  clock-for-clock, Ivy Bridge is a little faster.

 

So, Ivy Bridge overclocking is a little different.  Some will contend that it's not different but a little inferior because the potential maximum overclock is lower, but these CPUs are still a little faster and more powerful than Sandy Bridge.  So when I say that Ivy Bridge overclocking is different, I mean that the approach is different when one knows what to expect.

 

In other words, I think the expectation is to top out at about 4.5 to 4.6 GHz on air just like how Sandy Bridge tops out at around 4.7 to 4.8 GHz on air.  Yes, some air coolers can allow Sandy Bridge to reach 5 GHz, but that isn't the average.

Even just to 4.0GHz. I even bought a CM evo 212 after market cooler, that i'm not even making the use of (it's already installed onto my cpu).
Okay, then i think i will upgrade my cpu to the i7 3770k and keep my current motherboard.
Anyone can help with the overclocking? i know its freakin easy, but i can't work it out.
EDIT: Actually, forget the i7 3770k... so many people got issues with this cpu and mobo combo.
3770k and p8z68 v pro gen3.
So i probably will upgrade both motherboard and cpu when i get the money. Or wait a bit more.

 

I can help you overclock.  You are right that it's really easy, and I think I might be able to make it even easier.

 

Let's try these settings in the UEFI BIOS and go from there:

 

  • Ai Tweaker:  Ai Overclock Tuner:  Manual
  • Ai Tweaker:  BCLK/PCIE Frequency:  100.0
  • Ai Tweaker:  Turbo Ratio:  By All Cores
  • Ai Tweaker:  By All Cores (Can Adjust in OS): 45 (this will be 4.5 GHz because 45 x 100.0 is 4500)
  • Ai Tweaker:  Internal PLL Overvoltage:  Disabled  (Note: enable this if Windows refuses to boot with these settings here)
  • Ai Tweaker:  Memory Frequency:  set this to whatever memory speed your memory is supposed to be at stock
  • Ai Tweaker:  iGPU Max. Frequency:  Auto
  • Ai Tweaker:  EPU Power Saving Mode:  Disabled
  • Ai Tweaker\  CPU Power Management>:  CPU Ratio:  Auto
  • Ai Tweaker\  CPU Power Management>:  Enhanced Intel SpeedStep Technology:  Enabled
  • Ai Tweaker\  CPU Power Management>:  Turbo Mode:  Enabled
  • Ai Tweaker\  CPU Power Management>:  all of the rest:  Auto
  • Ai Tweaker:  Load-Line Calibration:  Ultra High (this should minimize vDroop to its least amount)
  • Ai Tweaker:  VRM Frequency:  Auto
  • Ai Tweaker:  VRM Spread Spectrum: (this disappears when setting "Phase Control" to Extreme, and we will do that next)
  • Ai Tweaker:  Phase Control:  Extreme
  • Ai Tweaker:  Duty Control:  Extreme
  • Ai Tweaker:  CPU Current Control Capability:  100%
  • Ai Tweaker:  iGPU Load-Line Calibration:  Auto
  • Ai Tweaker:  iGPU Current Capability:  100%
  • Ai Tweaker:  CPU Voltage:  Offset Mode
  • Ai Tweaker:  Offset Mode Sign:  +
  • Ai Tweaker:  CPU Offset Voltage:  0.005
  • Ai Tweaker:  Everything else:  Auto, except for CPU Spread Spectrum.  CPU Spread Spectrum should be disabled for Z68 boards because having it enabled results in actual the BCLK being 99 MHz

 

 

  • Advanced\ CPU Configuration>:  CPU Ratio:  Auto
  • Advanced\ CPU Configuration>:  Intel Adaptive Thermal Monitor:  Enabled
  • Advanced\ CPU Configuration>:  Active Processor Cores:  All
  • Advanced\ CPU Configuration>:  Limit CPUID Maximum:  Disabled
  • Advanced\ CPU Configuration>:  Execute Disable Bit:  Enabled
  • Advanced\ CPU Configuration>:  Intel Virtualization Technology:  Disabled
  • Advanced\ CPU Configuration>:  Enhanced Intel SpeedStep Technology:  Enabled
  • Advanced\ CPU Configuration>:  Turbo Mode:  Enabled
  • Advanced\ CPU Configuration>:  CPU C1E:  Enabled
  • Advanced\ CPU Configuration>:  CPU C3 Report:  Disabled
  • Advanced\ CPU Configuration>:  CPU C6 Report:  Disabled

 

 

Now, once all of these are set, there will only be two settings that we will need to tweak going forward (and so this is where it becomes easy):

 

  • Ai Tweaker:  By All Cores (Can Adjust in OS) (this is the multiplier, which will be set to 45 for now)
  • Ai Tweaker:  CPU Offset Voltage

 

 

So really, overclocking Sandy Bridge mostly becomes a matter of adjusting only the multiplier and the voltage.  smile.gif (I don't know yet if this applies to Ivy Bridge too)  Unfortunately, it can only become this easy once you know what to do with all of these other settings!  hehe

 

If these settings allow you to boot into Windows, then can you report back what your full-load voltage is as displayed by CPU-Z?  For full load, I recommend running Prime95's Blend test for a few seconds.

 

Thanks, benceh!

I won't have PCIe 3.0 since i don't have an ivy bridge, will it be a problem with a GTX 690? I figured out i would have to overclock my 2500k soon for better performance, apparently there is a small auto overclocking feature on my motherboard no?? If yes, please guide me on how to do it xD.
If i get a GTX 690, and my current setup isn't fine, what should i upgrade too? Maybe get a Z77 motherboard?? as the chip of the GTX 690 will apparently run at a better performance on Z77 and X79 platforms.

I think you will be fine with the Asus P8Z68-V PRO/GEN3 and the 2500K for gaming. When I used the 2500K there was never a problem with any game as it is a very good gaming CPU that can more than handle any of the games out there today. The only issue would be the GPU, but if you are getting a GTX 690 you will have no problem with the board, 2500K, or GPU and will be able to handle any game much more than fine. Also, I do not think the PCI 2.0 to PCI 3.0 will be significant enough to matter.

I did change out my 2500K, though, for a 3770K when my kids needed a new CPU, and the 3770K worked fine on my Asus P8Z68-V/Gen3 after a BIOS update (I'm using 3201). No problem at all. I would not spend the money for a Z77 unless you just really want one. Also, I would not advise you to get a Z79 when you already have a Z68 board that would work with a 3770K for a lot less money and be very close to the same performace, as both would be far more CPU than any game needs today.

So, in my opinion, you will be fine with the Asus P8Z68-V PRO/GEN3, the 2500K, and the GTX 690, especially once you get the 2500K OC'ed.

Best wishes and good gaming!

Thanks for the explanation smile.gif

Now I wan to overclock my i5 2500K too but need some guidance as well. In the Sandy Stable thread, the PLL voltage is further tweaked, do you also do that?

I don't know how to describe what multiple 4K video playback is exactly, but it's multiple video playback of the 4K resolution:

 

http://en.wikipedia.org/wiki/4K_resolution

 

It sounds impressive to me.  :)

 

 

For approximately 4.7 GHz and under, I wouldn't attempt adjusting the CPU PLL Voltage because the only benefits that I know of would be to possibly lower the core temps and/or possibly allow for a lower core voltage.  I mean, the temps and voltage I have at 4.7 GHz are already so low that I have no interest in making any other adjustments, even if they could actually promise lower temps and voltages (as opposed to just saying "it might be possible").

 

Still, you can do it if you want, but I personally feel that it's not worth the time unless you want to make it possible to get lower temps and maybe even be able to use a lower core voltage.  Now, when I had my 2500K at 4.8 GHz, I experimented with lowering my CPU PLL Voltage and I had some good success, but I put my CPU back down to 4.7 GHz because these days all I do is use Firefox and I check my e-mail with Microsoft Outlook.  I also watch the occasional movie, but that's it.  Fortunately, 4.7 GHz is extremely easy for my 2500K to achieve, so that's where it sits.  Otherwise it would be at like 4.5 GHz or even stock.

 

So anyway, I recommend keeping it simple.  However, if you want to play around with CPU PLL Adjustments, then I recommend starting at 1.700V and then experimenting with voltages above and below that until it is stable.

Ok, but I think the 2500K is still one hell of a CPU smile.gif

Yeah, we have the same views. It would be a lot of time to tinker with the PLL voltage and I don't have that luxury right now, lol.

What do you think is the most efficient multiplier nowadays for the 2500K? I do occasional gaming but will dive into it a bit more in the future when I buy (possibly) a GTX 660Ti to replace my GTX 560Ti GPU.

I don't know if there is a 'most efficient multiplier'.  I just went with the highest overclock that I could with my Thermaltake Frio, and that was 4.8 GHz.  Well, I probably could have done 4.9 GHz, but the increase in voltage I needed from 4.7 to 4.8 GHz made me assume that 4.9 GHz would have required over 1.45V, so I didn't attempt it.

 

In other words, just overclock it.  smile.gif

In other words, just overclock it.  smile.gif

Ok. Can you guide me from the start again on how to overclock? frown.gif

I said to myself that my ultimate limit in temps would be 85C. So as long as I don't reach that temp while overclocking, I would increase the multiplier more and more smile.gif

Thanks, benceh!

1/ Could you link me the download for Prime95 and CPU-Z please?? (Virus free)
2/ So i have to change all my settings on my P8Z68 V PRO/GEN3 motherboard just like above?
3/ I OC directly to 4.5? Or should i first go to 4.0 than 4.5?
4/ After the overclock which i will do on tuesday evening (when i get home) or wednesday morning, how can i run the tests and see if the OC is stable? What numbers should i transmit to you so you can tell me wether it is stable or not?
5/ I need more details on this part please:
"Now, once all of these are set, there will only be two settings that we will need to tweak going forward (and so this is where it becomes easy):
[*] Ai Tweaker: By All Cores (Can Adjust in OS) (this is the multiplier, which will be set to 45 for now)
[*] Ai Tweaker: CPU Offset Voltage"

6/ If my system doesn't boot, what should i do? (incase).
7/ I have a cooler master evo 212 cpu cooler, is it enough for a 4.5-4.7GHz overclock??
8/ I hear some people saying you have to maintain and check once in a while the OC status, is it true?? I shut down my PC nearly everynight, and it is a sleep mode a few times a day (if this has any influence).

Thanks mate. Will be testing the overclocking by wednesday (not at home until tuesday evening).

Actually, everything I said to Benceh in this post can apply to you as well because when it comes to overclocking, your board is the same as his.  So, can you do everything I'm asking him to do?

 

Thank you, Kevin!
