Asrock p67 professional (fatality) overclocking woes

[HumblePie]

I got every part for my sandy bridge system in yesterday and put it together last night with no sweat. Tonight I decided to spend some time overclocking to see what my new system is capable of. First off, I bought the following

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

The rest of the parts are what was in my i7 930 rig in my signature.

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.

Finally found some help to this problem if anyone is interested in knowing the solution and has the same board I have.

First, speedstep must be left on. The C state can be on, if you want to use the lower idle speeds for lower power consumption, but I left them off for testing for now.

With speedstep turned on, I can have manual access to the turbo power limit options. There is a short and long limit. I am not sure exactly what these options are doing but here is the changes I had to make. I had to up the short limit from 115 to 180. I had to up the long limit from 95 to 140.

That was the most unintuitive piece of overclocking I've had to do in a long time. Right now I'm holding steady in prime95 at 4.8Ghz@1.4v for the last hour. My speed hasn't dropped at all and I have a high max temp of 68C on Core #2 so far. Going to let it run all day during work.

Hi Humble...just registered myself to say THANKS!
That's exactly the prob I was struggling with - have had the speedstep disabled as well. Lets see what I can get out of my Sandy now - cheers

You are welcome.

I've since settled to 4.8Ghz at 1.45 volts to be perfectly stable. I was stable prime for about 5 hours or so at 1.4 volts, but sometimes it locked up. I got it to be stable for prime95 for about 20 hours and then ran lix and was stable at 1.44 volts. Unfortunately it locked up a couple times during games. I heard that SB was odd about that. Being perfectly stable in prime95 and other stress tests, but locking up during games. Many assume it has to do with the lack of a PCIe lock for the cpu and chipset. So a final bump to 1.45 volts and I'm holding steady. With a corsair H70 I'm reaching a max temp of 75C on core 2.

I can boot and run most of the stress tests and benchmarks at 5 Ghz but it takes around 1.5 volts to do it. I also reach 80+C temps too. I'm not exactly wanting to push that much voltage through this chip or those temps for 24/7 operation. I didn't get the best overclocking chip at all, but I got a decent one.


Key things about the motherboard though. Make sure when overclocking to set the load level to Level 1. This is the "drop" in voltage it level the board will apply after booting into windows. The default is Level 5 and that is crap for overclocking. Level 5 in my case means I start at 1.45 volts, but it drops to 1.2 volts and that is not stable for me at all.

Good info m8te
these P67 are dif - they are not meant to run straight out one speed like prev rollouts
If you fight it you lose

Hello!
I have a problem overclocking my fatality. I tried the "Load optimized CPU oc setting" Because i realy a noobster at overclockig and even 4.2Ghz settings were not stable. I left everything else on auto.
Can you give me some hint how to get 4.4-4.6Ghz overclock. And my cpu is 2600k and i have 8G 1600 hyperX memory.

Hi exact same spec (CPU + MOBO) as you, but i want to try get to 5.0Ghz. I have full water cooling (rad, pump res etc) but i am only able to get 4.9Ghz @ 1.6V on Vcore Stable.

i have tried 1.7V @ 5.0 but aint been able to post. I also tried adjusting the Load levels but i get a "machine check error" or something like that...

I know each CPU is different but could you post a screen shot of you adjusted BIOS settings to get it loadable in 5.0Ghz... its really bugging me lol

Appreciate any reply

Chris

1.7 Volts. Wow. I hope your OC to 5+ GHZ allows you to increase your productivity and work really fast on whatever you're working on that you need more speed, because I'd guess you'll have a full month before your CPU goes belly-up. But it will be one great month I'm sure. Just make sure you get the screenshot so you can post it on the msg boards, cause hey, that's totally worth the price of another $300 to get a replacement chip. Can't put a price on that screenshot!

Holy newbie attack batman!

 

[Longywales]

Wait a minute.

All i said was that i had attempted the clock at that voltage to see if it would post and it didnt. Im not running it at this moment. So dont get all geeky and offensive on me and act like im a noob, cos im not. Iv been overclocking for about 5 years, and since i been doing it i have been experimenting with all sorts of settings to see how they behave.

Seriously if you dont have anything useful to say dont, i wasnt talking to you guys i was talking to the guy/girl who posted that they achieved 5.0Ghz and i want to try get help from them

Jeez

Not the same Mobo, but similar settings may get you headed in the right direction..

If you can't get 5.g with 1.5v - I would think you may not have a happy chip..

1.6 - 1.7 might damage your chip in short order..

P.S.

Naming a board " Fatality " really doesn't bode well IMO .. :biggrin:

Has nothing to do with being a newbie.....there are plenty of veterans on these various boards who love to see how high they can go and they run massive voltage. I've just never seen anyone talking about one point SEVEN volts on these. Look, I have no idea......I just couldn't resist making a poke. No offense friend.

 

[bankster55]

2600K @ 1.7V????
I cant believe 1.7 didnt fry your CPU
At the very least your chip aint long for this world

 

[Longywales]

Thanks for the guide i shall have a go later on.

Well my chip must be a beast then if it hasnt blown up, or maybe your over reacting....one of them

Thank you so much for your help. Im finally stable at 5.0Ghz @ 1.535V. Anythign less than that voltage and i BSOD

The problem i had was LLC (Load Line Cal) setting was set to Auto and it obviously went to low, so i set it to Level 5 and shes steady as a rock, idling at 40 degrees watercooled. Under stress i get about 60 -65.

Well impressed with these chips. I jumped shit from AMD because these chips got loads of potential and are really cheap. 3.4ghz to 5.0 is a monster!

Sad thing though, my rating under windows index is only 7.8...its a shame because thats the only one thats not 7.9. Really annoying!!! what can max it out like lol

Last question tho, i read on another forum/review that its impossible to stop these chips going to 16x multiplier idle? its a bit of a shame because i would like to do a benchmark at a permanent x50 because i notice that sometimes during tests it goes to like 48, 49 and then back up to x50

Hi,

I get 5.3 GHz with my i5 2500k cpu on the asrock fatal1ty.

With variable voltage/multiplier, to save the planet.

As you can on the hyperpi pictures, above 2 cores,
the multipler is getting reduced after the time indicated in the bios (4 seconds) to
avoid overheating the cpu, and so crashing the system.

http://users.skynet.be/xixou/bios_settings_5_3_GHz_i5_2500k_asrock_fatal1ty.zip

Note: In the bios there is a typo in my opinion:
"long duration maintained" is actually
"short duration mainained", as the 4 seconds applies to the 140 Watts
setting (verified with my power meter).

So, during the rest of the test, above 4 seconds,
if 3 or 4 cores are used, the multiplier drops such
that the 100 Watts limit is not breached.

i5 2500k TPD is 95 watts, my cooler can cope with 100 watts (air cooler)

What is your ambient temp ?

Using ' auto ' overclock is probably pushing your vcore past 1.5, in which case, a temp like 82, sounds about right..
