Sandy bridge throttling problem

Im having some annoying problems with my new built sandy bridge system. I have a powerful watercooling connected to it so its not related to temperatures.

Whenever i go above x42 multi and i start prime95 it will drop back down to x42 after about 10s. Right now im running prime on 4,2ghz 1,25v and hitting 43C and its working like a charm. But if i run 4,3ghz with anything from 1,25v to 1,45v it will still drop down to x42 after 5-10seconds..

I have a 2500K and a Asrock P67 PRO3.
I have disabled the stuff that is mentioned in the "guide" (http://www.xtremesystems.org/forums/...02#post4697802) and all other voltages are untouched.
Any idea on what it could be?

Just checking to make sure you..
Check settings for something related to tdp, turbo power limit, current limit and up'd it?

Maybe you can give a try to ThrottleStop.

The TRL button lets you adjust the Turbo Ratio Limits on the K series CPUs and the TPL button lets you adjust the Turbo Power Limits.

And you can play with multi too with ThrottleStop.

No change im afraid :/

I found a setting that changed the current to the cpu. It was set to maximum 150 now and i changed it to 225, no change.

Did you click on that Turn On button on TS? Otherwise it's in monitoring mode.
But if you change the limit in BIOS and nothing happens maybe the problem is elsewhere. :(
Maybe Kevin will take a look at this thread.

Actually when i press "turn on" the multi goes down to 16 and stays there. No matter what regular multi i set in the program or what turbo multi i set :/

That would be great :) Lets hope he does.

I haven't done any testing on the new Sandy Bridge CPUs but when you click on the up gadget beside the Set Multiplier box, it is supposed to show the word Turbo when it maxes out which indicates you are telling the CPU to use full turbo boost. Something could be a little different in Sandy Bridge so I might have to wait for burebista to do some testing for me when he gets his new rig going. What multiplier range does ThrottleStop let you select?

Did you try increasing both the TDP and TDC values? This will work even when ThrottleStop is only in monitoring mode. You can also adjust the Force Turbo TDP/TDC number in the Options window to a low number like 8 to see if that helps. It sounds like you are hitting the maximum TDP / TDC limits for this chip and are being throttled back.

Yes i can adjust up to 33 multi, after that it just says "Turbo".

No, where can i adjust them? I will look into that when i get home from work.

Now i have updated the bios and from nowhere i got more settings. But now it wont load win 7 anymore.. Just bsods when loading Win 7. Does not matter if i run everything stock or overclocked.. -.-

what stepping and what option?
CPU PLL OVERVOLTAGE? if you have a D1 es chip then yes you will bdos with that setting enabled. What power saving features do you have enabled?

With bios 1,6 i get the CPU PLL OVERVOLTAGE option. But with that bios i cant boot into windows at all. With bios 1,5 everything seems to work. I dont have that option but now it atleast boots.

I also noticed if i have speedstep active i get the option to change the wattage during short and long time so now its not throttling anymore :) Although i cant seem to boot at higher than 4,6-4,7.

No i have a retail chip. Not sure if its a D1 or D2 but i guess its a D2. I have a L040B544. Basicly all power savings is off.

Right now im running prime95 at 4,6ghz and 1,26v. No problems so far. Will PLL overvoltage help much? Just hope asrock releases a stable bios with it..


Edit: Running 4,7ghz with 1,248v right now..

When using ThrottleStop, first you need to increase the Set Multiplier adjuster until it says Turbo and then click on the TRL button to adjust your CPU's Turbo Ratio Limits or you can click on the TPL button to adjust the Turbo Power Limits.

If you still have multiplier throttling issues at full load, it might help you get over the hump. ThrottleStop should let you adjust the turbo multipliers from within Windows so if you are having a problem booting up reliably, you might be able to boot up at a reduced multiplier and then use ThrottleStop to take it higher.

I have bypassed the throttling issue now :) I found the wattage limitation when i had speedstep activated. So now its not throttling. But what does the CPU PLL OVERVOLTAGE really do? Since there is no stable bios released yet for my Asrock MB that has it activated.

it allows you to overclock higher in many cases. Somtimes for no reason you will be stuck at a certain multiplier no matter the voltage, and then it allows you go go furthur when enabled.

Ah okey. Thanks for the explanation.
I can only hope that Asrock will release a stable bios which supports it then :/

I'm in the same boat as you are. I am having a heat throttling problem with my asrock board and I can't figure it out at all. First off, here are some of my parts.

CPU: I7 2600K
Memory: 16GB (4x4GB) G.Skill DDR3 1600
Motherboard: Asrock P67 Profess1onal Fatal1ty board
Cooling: Corsair H70

Here's the problem I'm running in to. Heat throttling. I've tried all available BIOS's possible for my motherboard. It came loaded with bios 1.3 though.

Now I know what you are thinking. I need to turn off all the C states and speedstepping. Well I did all that. In the OC Tweaking category of the UEFI BIOS there is a speedstepping option. I've tried with it disabled and enabled. In the Advanced -> Northbridge Category there are 4 different options that deal with the C states: Thermal Throttling, C1E, C3, and C2/C6 state options. I've tried every combination of those enabled or disabled possible with all BIOS options.

Here is what I have found out so far though.

I can boot in windows and run everything at the following CPU speeds and voltage settings with all steppings turned off.

4.4 Ghz = 1.30v @ 33C idle
4.6 Ghz = 1.35v @ 34C idle
4.8 Ghz = 1.40v @ 36C idle
5.0 Ghz = 1.48v @ 39C idle

The problem comes the moment I hit 50C temp. I drop down immediately to 4.2 Ghz. The moment I hit 55C temp, I drop to 4 Ghz. Anything over 60C drops it down to 3.9 Ghz.

It is very frustrating. Also, if everything is enabled (speedstepping and such) I idle at 1.6Ghz speed. The moment I turn on Prime95, I jump to the max speed I set in the BIOS until I reach the temps I listed above and then I start throttling.

I am thinking it's a problem with the current BIOS's for this board. I'm quite annoyed right now at this. Anyone able to think of anything I might have missed? Also I tried disabling the "heat protection" option in the hardware monitor part of the BIOS. I've tried PPL overvolt protection both ON and OFF as well.

That does definitly sound like the same problem as i had before.

What you need to do is first turn speedstep on, if you turn it off the settings you are about to change will dissapear.
Then look for "Turbo power limit", it should be right below speedstep in the overclocking section. Change the "Turbo power limit" to manual and then you have to find the right values for your system. Im running 180w short and 140w long and that seems to have solved my problems.

Hope it helped some :) Please let me know how it turns out

I'll give it a try later tonight.

I kow which setting syou are talking about.


Did you leave off all the other C State options though in the northbridge category still?

Actually decided to try right now before heading to work. Seems to be doing the trick. Holding steady so far at 4.8Ghz and running prime95 now. Going to leave it on for work. Highest temp so far is 63C.

Ah good then :) I was like WTF when i couldnt overlock above 4,2 but then i got help and found that setting.

Hope it works for you :)

Sorry, but I have to giggle at the P67 Fatality board you have Doc, its just a silly board "endorsed" by Fatal1ty, and hence, you pay over the odds. You could of got the exact same thing with the Extreme6 in a much more pleasant colour scheme :)

How are you getting on having to look at wendels mug every time you enter the UEFI? :p:

Anyway, on a more related note when you come to tweaking your memory to get a bit more out of it without having to jump to a different divider be sure to adjust the VCCSA voltage before tweaking with the BCLK ;)

Could you please explain what the VCCSA does? in terms of memories and BCLK.

VCCSA Voltage - 0.9v - This is the System Agent voltage (part of the CPU that isn't the cores), and after extensive testing, there is no real need to adjust this much, at least not at this stage.

VCCSA is the voltage to adjust if you want to increase your BCLK clock by any "noteworthy" margin. At stock volts (which should be 0.925v) you might get another 2-3MHz on BCLK. Increasing VCCA to a touch over 1v may allow you to squeeze 105MHz BCLK, and 1.1v might allow you to reach 107-108MHZ BCLK. I wouldn't advise going above a VCCA voltage of 1.1. Each 1MHz BCLK increase equates to about a +19MHz jump in memory frequency.

The reason the BCLK clock can't go very high on SB is because of the architectural design. When you adjust BCLK, you also adjust the PCI-E bus speed. Currently theres no way to lock down the PCI-E bus to freely allow BCLK adjustment on SB. If it is possible to lock PCI-E it would most likely involve some kind of divider settings although what performance impact this method would have if it were to work I can only guess at. Latency on the PCI-E lanes would likely be heavily effected.

Not sure, this is just my guesses but i think if you put it to high there should be a chance that the cpu stresses the board to much. Maybe there is a chance of burn mosfets or something.


Nice speed, but i have achieved 5328mhz on water ;)

The reason I went with the fatality board is because I liked the color scheme, I liked the layout, I prefer the snapping plastic pieces for the PCIe slot on it over the extreme 4 and 6 boards, and I liked the extra Marvel Sata III ports. Now that the Intel Sata II ports are suspect, this is an even better thing to have in my opinion since I have 6 Sata ports I can used instead of just 2.

I also disabled full screen logo during bootup so I dont have to see the face. Yes I have to see it in the bios, but here's my standpoint. I get everything adjusted and how often am I going back into the bios after I have it set the way I want it? Probably never again.

So I didn't mind the $30 bucks I paid to get basically extra marvel sata III ports over an extreme6. To me it was worth it especially with as many drives as I have and now I don't have to buy a sata controller card for that price.


Also, that short and long turbo limits were the key to stopping the thermal throttling. I find it strange though that this is the only board with this peculiar problem and solution.

Actually in terms of functionality fatality over extreme6 only IDE,thats all :)

Extreme4 & 6 have short and long (W) settings as well ;) As for stuff like thermal throttling.. I always turn that off it still doesn't really work right. Speedstep is all you really need. Extreme4 & 6 also have quite a few SATA3 ports, Extreme4 has 4, and Extreme6 has 6 I think. In the UK at least, the P67 Fatality is stupidly priced @ £200+, the Extreme6 @ £150, and the Extreme4 @ £115. With all the stuff crammed into the Extreme4 it was too tempting to pass on otherwise I would of got the Extreme6.. still might :D

yup, fixed for me, moved up to 4.6 Ghz today, will be going higher as I'm on water too.

short and long (W) were keeping my chip throttling back though. I enabled speed step and changed the settings and away we went. :up:

I've got 2 more questions about the ASROCK p67.

1. Can I disable the annoying post beep from the board?
2. Why does the board power on, off then boot normally? can I disable this?

Yes you can (Extreme4 here). Disable Spread Spectrum and no more double-POST. Instead you'll have BCLK 99.8. :D

hrmm mine is already disabled. Is 1.50 or 1.70 a better bios for Pro3?

If I disable spread spectrum, I can't boot into windows at all. I still get the beep as well.

The beep is annoying but nothing major to worry about. Not like the throttling issue.

So is there anyway to keep the chip from backing to 1.6Ghz when it's idle with Speedstep on?

How about go into the Control Panel -> Power Options and set the Minimum processor state to 100%. EIST on is OK but try disabling C3/C6.
What does RealTemp show when you do that?

I would start with shipping UEFI, if you get problems, step up one UEFI version. With UEFI causing issues atm you have to try one at a time to hopefully find one thats not going to cause problems. I'm using 1.3 on my Extreme4 because its a lot less flaky than the most recent 1.5.

All the power management stuff in the bios is already disabled (c3/c6). But like the original poster in order to bypass the power usage throttle I had to enable speed step to access the long and short (w) settings which cured that.

The suggestion to change it in the control panel sounds more likely now. I'll have to check that.

Does it matter the CPU clocks down to 1.6GHz when you are just on the interwebz? :p: The instant the CPU goes under any kind of load it shoots straight up to whatever your OC is. It does on my Extreme4 at least with the throttling options disabled.

yea thats what its doing for me too. I'd just prefer to always have it show me 4.8ghz lol. One of those things. I guess less power at idle is good.
