Idle Bluescreening......ANy ideas?

[Firat]

Hey all,

i have a 2600k at 4.5ghz under water on a z68-ud7 its at 1.32v LLC at idle and on load. its 48h prime stable and 1 week stright F@H stable.

at idle when im watching movies mainly the screen freezes only happens when i watch movies for some reason :S the BSOD.

now does the cpu require as many volts as it would on load, is there too many volts going throught it on load?

what do you guys think?

Thanks

broken codecs more likely

try these: k-lite mega pack http://www.codecguide.com/download_mega.htm

thanks ill try them out... so you dont think is an overclocking issue?

CPUs when overclocked can deterriate overtime... but you only have a 4.5OC WC'd, and the 2600K is not that old

this can only suggest that it is a software issue

Hi,

It might be an issue that certain tasks only stress ONE core, whereas benching or folding would normally stress ALL cores. I'd suggest, with you being at 4.5 ghz, that a slight bump in LLC and if possible a slight drop in vCore (do one at a time) might help your stability.

See my post here were I have a Prime 95 and IBT stable system, but experienced odd Crashes (not necessaritly blue screens) at partial CPU loading. Link to forum thread

It could well be a simple codec issue, but as you're overclocking there might be some stability issue there. For the record I always just apply the latest K-Lite Codec pack. There are versions for just playing stuff (lite), a version to enable you to do basic encoding (Basic) then there's one that give you loads of extras too...I just download the Standard one.

FYI: at 4.5 on my 2500k I'd see a vCore of 1.336v at load. My friends 2600k seems to need a little more for stability. All chips are different of course.

Best of luck.

the codec hasnt solved my issue, i still Bsod/freeze/stutter during movies online web players.

im at 1.332v on load nad idle LLC the question is on idle is there meant to be less wolts going through or more im confused?

btw error code ends in 00124

thanks

0x124 for Sandy B usually mean too little or possibly too much vCore, though more likely the former.

Yes, your CPU should report a lower vCore at Idle, my 2500k for example reports 0.960 vCore when idling at 1.6ghz, but 1.366 vCore under load at 4.5. On some boards (my prior MSI G45 for example) once I'd set a manual vCore it would NOT then reduce vCore at idle, making things unstable. Thankfully my Asus board works properly. Note: do check you've not turned off the relevant Idle states - check your motherboard manual for the exact settings as it can differ between manufacturers.

Btw: you say "idle LLC" - exactly what is your LLC setting? For example, on my Asus board I had it set to "High" - which despite its name is the normal or default setting. I've very recently gone to 4.6ghz and I needed an LLC of "Very High" to remain stable. As per my other thread, I was 100% Prime and IBT stable with only "High" LLC at 4.6ghz but needed to turn in up a notch to be stable in partial load situations, i.e. when only a couple of cores were working hard.

In theory, assuming your GPU isn't doing the work for whatever reason, playing a movie might just work ONE core.

on the ud7 gigabyte board there are 10 leveles of LLC and im on LLC 6 which basically keeps you vcore the same when idle and on load.

i ran prime & intel burn test on 1 thread and 2 threads and 4 threads and 8 threads with no error.

my idle clock is 4.5ghz also so i have a static clock not like yours at 1.6ghz

Right, I see what you mean. I found my system (on the old board, didn't try on the new) to be far more stable when I let the CPU idle @ 1.6 when it wanted to. A decent board will adjust the vCore accordingly.

Basically, as I understand it, my board will read the VID for a given multiplier, so at 16x (1.6ghz) my VID is 0.960v, at 46x (4.6ghz) it's something like 1.330v (not exact, I cannot recall) LLC either negates vDroop (under load) when at a neutral setting, keeping vCore constant or gives it a bit of a boost if you turn it up. Lower settings apply less vDroop compensation. To be stable my CPU needs a slight boost at 4.6 over and above the offset value I've already set.

My offset value in effect adds 0.050v to each multipliers VID, but by 4.6ghz I need LLC to give it a little bit more under load.

I'm still learning and refining my overclock, but I'm making it VERY stable under a while variety of load and idle situations.

My CPU actually seem to run cooler at 4.6 than it did at 4.5 despite me adding 0.010v to the offset vCore value and turning LLC up one notch. Performance is better, but only noticable in benchmarks of course.

Do you have speedstep enabled, and what are your vdroop settings - This is overclock related as it happened to me.

Speedstep is disabled, for a constant overclock my bios settings are 1.35v and LLC 6
