Yea, I dont know know where he got that? Maybe its just a gigabyte thing. I havent owned any gigabyte p67 boards, but I have heard they are having some problems.

But I can crank my oc up to 5ghz with offset, and all power saving features enabled with absolutely no problems.

Happens to me happens to my friend how has Asus P67, I guess it really depends on the CPU it self.

Yeah I've owned 3 P67s along with a Z68 and have yet to experience what he claims. I even explicitly use offset when I overclock.

Yea me too. I always use offset, that way my voltage drops when idle. I have yet to experience instability during idle.

You know what I think is happening? I think the people who are experiencing idle instabilities supposedly caused by cstates, are actually just unstable overclocks period. I think they either didnt stress test long enough to get a bsod, or they thought they were completely stable and in actuallity are not.

Not to sound rude or anything, Im no expert on sandy bridge. However, I do have the basic experience needed to know that offset does not cause instability when used in conjunction with cstates.

If you have instability during idle then your overclock is unstable, period. It is not because of speed step, or any of the c-states. Its unstable, period.

Then please explain why disabling C3/C6 allows me to be stable at idle, longest I've tested is about 9days.

If I bump up the offset +0.010v then I can get C3/C6 working. Maybe you guys can perform this test for us as well, with your stable offset voltage drop it by 0.015 less and try to check if it does not BSOD in idle for a couple of days.

Your theories/accusations dont really translate anything well to this thread, if no one can contribute aside from just saying Cstates dont cause instability then please keep out of the thread.

Ok, well I got bored, reinserted my "Dud" clocking 2600k, and decided to use 5 ghz with offsets instead of fixed vcore.

First, I enabled C3, C6, C1E and EIST. This game 1.6ghz at idle and 1.152v or something, and 1.5v and 5 ghz at full load. I noticed something really freaky, though. When I was in windows 7, I saw the CPU clock often going between 4700 to 4900 mhz and the vcore around 1.35 to 1.4v. was pretty interesting.

Something ELSE I noticed: in windows 7 (only)
When I turned on C1E, and C3/C6 (EIST still on), this caused the cpu cores and voltage to downclock, even with the windows 7 power plan set to "high performance." When I ONLY had EIST on, and everything else turned off, windows would downclock the cores and voltages, ONLY if it were set to "balanced"; with high performance on, it would keep max clocks/voltages. With EIST disabled in BIOS, it would always keep max clocks regardless of power plan.

Playing Crossfire (a game) in windows XP (not installed on W7 partition):
With C1E/C3/C6 enabled, had a light load BSOD while in the CF lobby.

With C1E/C3/C6 disabled, no BSOD at all.

So yeah, I'm having the same problem as you with them enabled.

I'll try enabling ONLY C1E and see if that changes anything.

BTW another strange thing:
When I was in COD Black Ops main menu, the CPU wasn't running at full speed...was running at like 4700 mhz.

ANOTHER stranger thing:
If I used a FPS cap in Black Ops (like 100 FPS), the CPU would run at SLOWER clocks,and would drop the voltages. The higher the FPS cap, the faster the CPU clock would be (along with drop or rise in voltages). If I set the max FPS to 0, then the CPU ran at 5 ghz....

I THINK I have an idea now why you are getting idle or light load bsod's.
I'm guessing that the CPU is downclocking, and using an "improper" vcore to keep you stable at thet lower clock. For example if you need 1.4v load for 4.8 ghz, and its giving you 1.36v with the downclocking: bam: BSOD possible. And the ONLY way to avoid that is to use a higher offset or higher LLC....(I do NOT know if only having C1E enabled will fix this).

Maybe the vcore being given to the CPU has something to do with the SVID the CPU is reporting at a ceratin speed...or maybe the vcore being given is sometimes not high enough I guess....

*edit* just found something else.
With ONLY EIST enabled and using a balanced power plan,
Running 1 thread superPI instantly ramps the CPU up to full speed and vcore with just the 1 thread.

When I had C1E, C3 and C6 all enabled, and using high performance power plan, it seemed to "lag" at first, that is, it seemed to take awhile before the CPU ramped up to full speed, thus the first loop was a lot slower than it was supposed to be. <--this could very well be causing your light load BSOD here.

I'll try with EIST And C1E enabled only, and high performance power plan.

*edit again*
Hmm...looks like C1E *FORCES* "speedstepping" via the hardware directly, while EIST forces it only with software support. With power at high performance, having C1E enabled and EIST disabled did the exact same thing as power at balanced with C1E disabled and EIST Enabled (both allowed downclock of vcore and mhz).

NO idea what C3/C6 do >_> Now I do...

Alice:
Please read the thread on HardOCP.

There's a MASSIVE thread on idle BSOD's when using offsets, on the P8P boards. Many of these BSOD's were fixed by DISABLING C3/C6. It's nothing to do with being unstable naturally. Other people were having freezes (instead of BSOD) at idle, but that had to do with XMP and RAM issues.

So yeah..it helps some people..
I'm still testing it...trying to use only C1E (EIST and C1E do the same thing btw...C1E is forced through hardware while EIST is forced through the OS itself, and is controlled by power options, while C1E is NOT controlled by power options. I honestly do nOT know what C3 and C6 do, anyway, nor do I care....

And, Alex and lethalrise,
You two really need to stop flaming me. I read forums religiously and I followed that C3/C6 freeze thread on HardOCP for months. Do you actually think I made up that thread and made up all the posters who are having problems, claiming its from my imagination? Seriously--you guys have more experience in computers than this--you should know better than to insult somebody just because YOUR system is working fine. If YOURS works fine and C3/C6 works great, then great!! awesome!! But just because you don't have problems does NOT mean that someone else with the same board won't have a problem !!! I would have thought you experienced builders would know this by now.

That's about as silly as saying "degradation doesn't exist: I ran my CPU at 1.5v for 3 months and it's STILL stable at 1.5v"--haven't you heard of the "bandwagon fallicy? (aka hasty generalization)" They teach that in college, you know....

BTW you know that C3/C6 states have to do with complete core shutoffs for power saving (just found this out), and aren't required to have your downclocking to 1.6 ghz and vcore down to 1.1v...really no need to save 10 cents a month on your electric bill by using C3/C6...especially if it causes a problem on someone else's system....

Quote:
C3, C6. This is a deeper sleep with a complete core(s) shut down (Gate off) and no voltage/Data at all. harder to recover from quickly, previous data is cached elsewhere and needs to be re-cached in L3 memory
to re initialize full muliticore, multithread use. Part of Core parking
http://download.intel.com/design/pro...=tech_tb+paper
Now I can FULLY see why some people may have idle BSOD's with C3/C6 ...
And that also explained the weird "lag" I had when starting superpi when I had them enabled too (Only the first time).

@Earl:
No need to bother using C3/C6. It doesn't affect downclocking at all and doesn't affect EIST (controlled by OS) or C1E (controlled by hardware, not by OS). And enabling it (which crashes you) may save you a dime a month on electricity. Big whoop...

*edit* I was partially wrong earlier, as the problem isnt with offset voltages but with C3/C6. I incorrectly mixed them up and assumed C3/C6 were part of making offsets work with downclocking and you only need C1E (OR eist) for that, so my bad, there.

Falk,

Thanks for sharing, I find it very informative and it also goes with what I thought. On my end say If I load up only 3 cores with C3/C6 the Vcore is about 1.320 but with C3/C6 disabled it loads up 1.360,

Yeah I guess I'll just disable C3/C6 to save me the trouble and not be forced to use higher offsets!

This low load issue is a bit annoying as the guys over at PCSX2 forums believe that my low load OC is unstable, Im thinking of just dropping C1E instead as I believe having my voltage at 1.368 24/7 should be safe.
