Hi all,

Some info about my system, this is a new system (edit: I updated sig with spec)

This is a 4770k and I try the 3 step booting and could boot into windows and crash right away at 1.2 volt and 4.6gz. Upping my vcore to 1.25 and lower overclock to 4.5, the system run very well for a little over a month. I can actually run light application,surf the net and stream video as low at 1.2 but crash once I star gaming or rendering.

After over a month of testing and following others result this is what I can determine about my chip. 4.5 at 1.25 volt, 1.32 at 4.6 and I can boot and run the chess stress test at 1.35 for 4.7 but I am sure I probably need more. At over 1.3 volt i get failure due to heat, I get the clock watchdog timeout message.

I been following the thread and I can say I have a decent overclock at 4.5 at 1.25 volt. I am right now limited by my cooling solution as the H100 I have struggle hard to keep it under 100c once I push 1.3 volt for 4.6. I have been thinking that my H100 is defective for awhile since it is the worse cooling solution I have ever had. I have one question right now, I am sure it is related to my Vring but want some others opinion. I was running stable with no crash at 4.5g, vring at 35, memory at 1600, vcore at 1.25 and left vring voltage at auto. I oc memory to 2400 a week ago and no problem. The last 2 days I pushed my vring up to 42 and added as high as 1.2 voltage and I get crash but no error report of any sort. No blue screen, no 124 error code, nothing but ,

I really think this is vring related and would like to know what you all think.
My setting at the moment is:
4.5ghz, 125 vcore, drop vring to 42, vring voltage at 1.2, team xtreem memory oc to 2400, memory voltage set to 1.65,. I have set the memory to 1600 and ran it for a month like that and just oc it to 2400 last week with no crash until I played with the vring.

My batch number is L307B239 Malay. Chip is a 4770k

I will post pic of the system later as I need to go get diapers now biggrin.gif

I am wondering what it mean when I crash with no bsod or error code and don't seem to get anything in the log.

Yeah, thats what your supposed to do, lol. That might have been the reason i doubted you for a second biggrin.gif But whateva, mistakes are made.

There really isn't much point (from a performance perspective) in pushing the cache speed - if you were stable with it at 35 then I would either leave it there or slowly move it up until you run into problems. Jumping straight to 42 probably isn't the best course of action. But, in addition to Vring, you can also try bumping up VCCSA and VCCIOD and see if those help with stability. You may also need more Vcore to run at the higher cache speed.

Mistakes? BS, can you explain the 0.000V Vcore values reported in the screen shots above? At least I take the time to document my settings and post them for others to see, while a bunch of you guys hide your settings and refuse to post any screenshots. How many members have even posted shots of HWMonitor or HWinfo along with their stress tests? Actually a very small percent. I went through the pictures in both threads yesterday and compared them to the results and several members have reported their CPUz values (FTW 420 is the most recent), so don't act like I am the only one. So in my opinion someone like yourself that refuses to post any shots of stress tests shouldn't be trusted because you are obviously covering up for your POS chip. So don't come at me with this crap above until we see some of your real Vcore stress test shots pal.

I try to help others as much as I can and I get condescending remarks like this one, well I guess the rep difference between us speaks for itself. You keep cracking jokes, acting like the peanut gallery, and pointing fingers at others and I'll try to make real contributions to the forum. Thanks for basically nothing...

A screenshot taken while the cpu is under load should show any vdroop or vrise that occurs, along with a screen at the end.

There is always going to be a kind of honor system as far as the voltages go, software isn't completely accurate but it is all there is for most people, when haswell first came out no software could read the right voltage so a guy's word was all there was. Not posting any screens does seem weird though.
I was going to compare cpu-z with hwinfo & hwmonitor on the multimeter, I'll have to get that done yet. I've always used cpuz since it is basically the standard, hwinfo is handy to see some of the other voltages though. Not sure if I've used hwmon before...

So what's your process for stressing? I've been going IBT -> Prime -> AIDA (CPU/FPU/Cache/Memory). Do you recommend doing anything differently?

Do I even bother worrying about passing prime with AVX (i.e. V27.9)? All the Haswell overclock guides seem to recommend just using AIDA.

Leaving your pc running synthetic tests is not good enough, like a night of IBT or prime95. Do your daily tasks while stressing your PC, browse web, watch youtube and maybe some encoding stuff without worrying of losing your data. That way you will test your stability while using your PC and not just waste energy. If something like a flash plugin crapping in while doing so - you may need to work on your stability;)

Please do that test if you can get some time and post the resukts. I think I speak for most people when I say that is a key issue for OCing z87. I personally only use CPUZ and HWmonitor, and I would be extremely interested in seeing how accurate those software are compared to a multimeter.

Ok so at 1.22 vcore, 45x multi I've passed IBT, Aida64 (CPU/FPU/Cache/Memory) for 12 hrs, Aida64 (FPU Only) for 12 hours, could encode in handbrake no problems and prime 95 ran for several hours. This included browsing etc while running these.

I may try dropping vcore a little to somewhere between 1.21-1.22 but otherwise I think I'm gonna call that stable and move on to uncore.

What do you think?

I think 1.22V for 4.5 is pretty good, and I'd be happy with that (or I'd push for 4.6, if your temps are okay).
