CPU clock multiplier topping out at 40 under stress

[Treynolds416]

YES, I READ THE ENTIRE STICKIED THREAD ABOUT THIS. I tried everything in there, to no avail.

Trying to overclock my i5-3570k, motherboard is an ASRock z77 pro4. Changing the clock multiplier in the BIOS worked great up until 41. When a stress test is not running, cpu-z and coretemp show that the multiplier is at 41. As soon as I start a test with prime95 or intelburntest, the multiplier will drop to 40 and not fluctuate from there. The same thing happens if the BIOS are set to 42 as well. The temps never reach 60 for prime95 tests, and get to only around 65 for IBT

THINGS I HAVE TRIED
- Changing multiplier of individual cores
- Disabling speestep (EIST)
- Disabling automatic voltage changing for core, IGPU, VTT, PCH, PLL, and VCCSA
- Setting Load-line calibrations to 100%
- Disabling C1E
- Disabling CPU C3 (ACPI C2) state
- Disabling CPU C6 (ACPI C3) state
- Disabling CPU thermal throttling
- Disabling Intel Virtualization Technology (vanderpool)
- Setting target fan speed control for temperature to 65 C
- Changing power plan to "High Performance"
- Changing advanced power plan to have fan control as "Active" (fan speeds up before processor slows down)
- Using ASRock extreme tuning utility to try and up the multiplier through the OS (Multiplier can only be increased by 1 from BIOS setting, reports the same multiplier drops as coretemp and cpu-z)

Please help, I'm losing my mind and I can't seem to find a solution anywhere

Have you tried clearing the CMOS? What about BIOS updates?

 

[Treynolds416]

Well I just updated my BIOS and still no change. It cleared my settings, too, so do you think clearing my CMOS would be worth doing?

 

[djsb]

Asrock motherboards, if they're anything like the P67 Extreme4 I have, have overcurrent and powerdraw protection. Their default settings are very conservative, so you need to manually increase them in order to prevent throttling.

 

[ShintaiDK]

Yep. You can set the max powerdraw in BIOS. Thats what you need to increase.

 

[Treynolds416]

Great, but how do I change it? I looked all around in the BIOS and I still can't find anything pertaining to power draw. Does it have a weird name or something?

Something with TDP or Watt?

And no need to disable EIST, C1E etc. besides wasting money.

I think its in the OC tweaker called short and long duration power limit. Plus the current limits.

 

[djsb]

Like I said I only have my P67 Ex4 to go by, but it if the Bios layouts are they same it should be below the CPU multiplier option, but above the voltage option. The overcurrent protection is probably the one that's throttling you.

Ok, I remember there being the short and long duration power limits options. Which does what, and do you have any suggestions for test values for either?

@djsb, I don't see an option similar to the one you're describing there

 

[john3850]

I had the same problem on 2 asrock boards once with the clock multiplier and once with the memory timming settings it was almost like the last N7 abit that would run out of space in bios and was unable to change the setting.
I cleared the bios as op suggested and that solved the problem fow the last 6 weeks.

 

[john3850]

My 68pro3 would always reduce the mulipilier x1 at 83c with 2500k.
I dont remember if I had throttling off.
When I ran prime at x51 it would throttle back to x49 and stay there for a while.

 

[Ed1]

Grab the latest CPU-Z version and what does it say for multiplier range , if you set it for 42 you should see a 16-42x shown . That to me says bios is ok but it may throttle with load (raise power options , I can't help on Asrock but must be guides around .

Isn't Asrock a sub-division of Asus cause this sound like Asus bios bug were you need to either reflash or clear Cmos (reflash seems to be best way ) .

 

[Treynolds416]

Changing the power limits didn't do anything, even when I upped them to 500.

@Ed1: CPU-Z does indeed show a range of 16 - 41 for the multiplier.

I cleared the cmos and when I reopened the BIOS the only thing I changed was the clock rate. The clock still did the same thing as it did before. Should I try disabling all the things I had previously tried before as well?

Ok, here how you can tell if you have the bios bug , it won't allow you to change multiplier , it might show ok in bios but as soon as you load windows it goes back to that last speed .

I personally would first take pics of your setting or write them down if F12 doesn't take pics within bios on your MB .
then set to default option settings , reboot then reflash to latest bios and see if it works ,(try 42-43x on auto just for test ).

I already did all that...

The cpu runs at the correct multiplier according to cpu-z, UNTIL I begin to stress test it

 

[njdevilsfan87]

There may be an "over temperature protection" setting that may need to be disabled.

Ok, I thought you orginally set it to 42x in bios but in windows it shows 16-41x in CPU-Z w/o load .
If it shows right with no load and clocks down with load there must be setting in bios . I would check some guide forums where many users run into same MB .

Oh, you do have in control panel\power options >CPU power management >max process state =100% .

thats long shot as you would have to lowered it .

 

[djsb]

Can you post screenshots of the OC tab in bios? The only ones I can find of that board are either low res, or weird photographs of monitors that I can't read.

[Treynolds416]

Yea, I had already tried changed all of the power settings in Ed's post. Now that the CMOS was cleared, I can try changing everything again in the BIOS that I listed in the OP, when I get home in a few hours

 

[Treynolds416]

It's been a while since I posted last

I tried all of the extra settings after clearing the CMOS and updating the BIOS, same issue. Does anyone at all know what's going on?

Your 100% sure you have a 3570k and not a 3570? Cpu-z shows as a K chip....About the only thing I can think of that's holding you back as it looks like you've tried everything that should work otherwise.

FUCK
ME

That explains so much... CPUZ shows no k. I don't have my order form from when I bought my parts over a year ago, but I have the excel spreadsheet I used for my parts and it's linked to a 3570 although it's written as i5-3570k. I remember thinking it was odd that the 3570k was suddenly $215 instead of $220 with no listed sales... Clearly, the lesson that we learned today is that you should always ask the seemingly obvious questions. And also you need to read every single letter of a component title, especially when it's the 11th letter of the alphabet.

Is there anything I can do to get the locked processor past 4.0? I bought it as well as an aftermarket cooler for the purpose of overclocking. However, even if it can't get above there, I'm satisfied because I at least know why it wasn't working before.
