Hi all, Had a strange BSOD about 2hrs ago whilst just browsing on the web "A clock interrupt was not received on a secondary processor with-in the allocated time interval". Now I have had a look around Google and looked at the code for this Bsod and it seems the V-core is too low but what I dont understand is that this has just started to happen?

Could my cpu be faulty? All temps are fine, Ram is all fine and tested with memtest and psu seems to be fine, I do know that that Asrock z68 boards have had this issue though can not find anything on my Gigabyte board with this issue.

I use Hardware monitor and that gives me two readings for the cpu, one is cpu v-core which is @ 1.06v and the other is 1.24v cpu, I also use the intel speedstep and other power saving features via bios.

Only had this cpu/mobo/ram about two months, So I am eager to get this resolved with-out the hassle of RMA.

Any Ideas guy`s would be greatly appreciated.

4ghz on 1.25V is probably your problem, either lower the overclock or increase the voltage a little until it stops.

As for why it's only just started did you test your CPU's stability when you first overclocked it? it could just be a difference in ambient/case temp or something it's been pretty hot recently.

Actually my overclock is @ 4.3 ghz though that dont explain why it bsod whilst browsing and running a low clock speed whilst power saving features are enabled. My initial overclock was tested for stability and I ironed out any issues then with 1DAY giving me advice.

Is there a chance that the power features are producing too low a voltage that makes it crap out?

It's possible. I tested this once by downloading some free cpu limiting software (it was really comprehensive actually, will try and remember which it was...) to limit the cpu usage of the stress testing prog to some value which kept it from stepping up.

I don't know if this constituted a proper test though, as it steps up way below 100% utilisation.

Well I have gone back to stock for now and I am testing prime small fft`s for a few hours to ensure that the system is stable.

After a little searching I found most people @ 4.2 ghz were stable @ 1.28/9v so .3v under that was probably too little volts for my 2500k. We shall see as I am gonna set my 4.2ghz OC at that tomorrow and see what it is like at those volts.
 
I think for sure @ 1.25v was not enough for my cpu and also what I have found out is I am suffering a little v-droop, for example at the moment in bios my cpu v is set to 1.32 and yet whilst running prime95 my volts are @ 1.30v via hardware monitor, I know the software is not an exact science but as soon as I stop prime95, the volts back up to 1.32.

The question is, how can I rectify this v-droop issue :confused:, right now I am just trying to get stable @ 4.2ghz, as I am happy at this point for a 24/7 OC but would like to see my Volts as low as can get them, I think ideally around the 1.28v range would be good as right now my temps are avg 70c across the 4 cores.

Thanks for your input guys! :)

I would up it by the smallest increments until it becomes stable, then up one more for good measure.

Right now it is prime stable for 4hrs at 1.32 but with this V-droop issue, under load it is showing at 1.30v but reverts back to 1.32 when idle, So ideally I would like to solve the V-droop if I can, So I know that the volts are accurate, otherwise at lower volts it might start crapping out under load.

Thanks joeyjojo!

is this a gigabyte thing? because my ASRock is lower volts idle and higher underload, which is the way i thought it was meant to be :confused:
have you tried changing the cpu LLC level?
Click to expand...

Yep LLC is enabled, you only have the option to enable the LLC on my Mobo and yes I always thought it should be that way too....A bit miffed on this Tbh!
 
Just found this

Quote:
There's a new Dynamic Vcore option in the Advanced CPU Voltage Settings. To enable it, set the Vcore voltage to "Normal" and then add or subtract the amount needed to reach your target Vcore voltage. For instance, my original Vcore in BIOS was set to 1.2750v. When I set the Vcore to "Normal", it is set to 1.2125v. Therefore, I set the "Dynamic Vcore Voltage" to +.0625v which results in my target voltage of 1.2750 = 1.2125v + .0625.

What this option does is set your idle voltage lower than originally (if you have power savings features enabled). For example, my original CPU-Z idle voltage was 1.248v and now it is 1.104v. The load voltage is unchanged. It's a nice feature to have.

let us know how you get on with it :)

Not very well mate, just been into bios and there is no option to enable it, it is set at auto :confused:, there must be a way to enable it unless it is coming in a bios update......F4 bios has been about a bit now and is still the latest Bios for this mobo!
 
I tried the dynamic V-core and the issue is still there under load, It doesnt change the load voltage as whilst running prime95 now, I am still sitting 0.02v under 1.30v, actually just checked hardware monitor and it fluctuates between 0.03v & 0.02v now, So in fact has made it worse, In bios it shows 1.283v So there is def a issue.

Still, I am sure there must be an answer to this somewhere!?
 
paradisiac said:
think the answer is wait it out for a bios update or replace mobo :( a lot of fiddling 'might' get you there though. have you tried different combos of th DVID to see if you can get the fluctuating numbers closer?
Click to expand...

Yeah gonna try playing around with it, to see if I can get it closer, Hopefully I can get a resolution, a bit busy this afternoon so will probably have a play this evening, Thanks for your help Mate, will let you know how I get on!

all this SB OCing is turning into a right nightmare for a lot of people. so many models use different option and nothing seems to be very universal. gone are the days of upping the fsb/multi and increasing the vcore (then any minor tweaks to other stuff to go higher).
Click to expand...

Yep, I agree the OCing it self is quite easy, but there are too many little things that hamper it.
 
I have managed to get the undervolt to with-in 0.01v, So it is set @ normal volts in bios and -0.55v (1.34v -0.55v=1.284v), It is now reading in hardware monitor 1.27v from 1.28v underload. Still not right but better than was before, Not sure why my board undervolts whilst underload though.

I will just have to take into account the 0.01v when adjusting my voltage.
 
paradisiac said:
the bios will ALWAYS read higher than windows due to it wont run any of the energy saving features.
maybe this is your issue?
Click to expand...

I disabled all the energy saving functions now and anyway the cpu-v has always been ok @ idle, Both bios and hardware monitor report the same volts at idle, only under load do I get the issue of V-droop, I do wonder how much V-droop I would get if I disabled LLC though, One guy on tweaktown had something like 0.08v V-droop on exactly the same board, So I guess I should count myself lucky :D
