Also, the freezes come after about 30-45 minutes of playing, sometimes 20 minutes which makes me think memory timings are causing the freezing.

Oh okay, fair enough. That description makes me think uncore still; for example when I try to boot a memory frequency at too lower voltage, it usually hangs at windows load screen. I suspect similar would occur for too tight timings.

best way to check memory stability is still memtest86 overnight tho... thumb.gif

I put my vcore down to 1.30v just for kicks and for the sake of trying out x264 20 pass. It failed sometime during the night, BSOD error 101.

Put my vcore back to 1.32v, where I've previously had good stability with, and am now running another x264 20 pass.

101 is usually too low VRIN, rather than too low Vcore.

It's possible 1.30v was enough Vcore for you all along, whereas your VRIN was too low but was compensated by excessive Vcore. I personally haven't experienced this scenario (if I 101'd due to VRIN too low, no amount of increased Vcore rectified the issue - i HAD to increase VRIN to stop the 101), but from reading this thread it seems some people may have experienced this.

Interesting point, however my VRIN is at 2.0v, which I was told is a rather healthy dose of VRIN for even 1.32vcore. If x264 20pass error's with BSOD error 101, do you suggest I raise the VRIN and only the VRIN?

hmmmm... that's pretty interesting. what multi are you trying to stabilise again?

- If the multi is 4.5 or below, then it may very well be a 101 due to too low Vcore.
- If the multi is 4.6 or above, then it could still be Vrin too low, Vrin too high, or Vcore too low.... (unfortunately, things get messy trying to stabilise 4.5<)

I am actually at 44x multi currently. Haven't even tried for 45x yet! Uncore is at a base level of x34.

could very well be a 101 due to low Vcore. haven't seen too many of them tongue.gif

could be 101 due to low vcore. It happens.. occasionally

If you set 1.32 vcore, you're getting ~1.34 at load, at which point ~2.0vrin isn't really that uncommon. I need 2.0 for my ~1.365/1.37 oc (1.345-1.35 bios)

I'm at 1.34 bios now (after i eat), because if i crash in two weeks to a 124 with 1.34v, it tells me a lot lot more than if i had set 1.35v and never crashed.

I see most people here is advanced overclockers and going to the limits of the chip, and i dont know if this topic is right to make noobish question or i need open a specific one. But lets try..

I'm new to intel, i dont have knowledge or experience with intel OC but have with AMD and i get my i7 4770k just 1 week ago, and was trying to understand the overclock settings.

I dont want to go too far now, because i have only a air cooler CM Hyper 212+ and just want to try keep the CPU at 3.9 or maybe 4.0ghz.

I got a Asus z87 Plus, and was trying slowly to make 3.7ghz fixed first, but i find some things what make me confused, when i disable turbo mode and go to "CPU ratio" and change from auto to 37 the turbo mode back to enabled. If i go turn turbo mode off the cpu ratio become auto again and i just cant set manual cpu ratio with turbo mode disabled. Is it like that and i cant turn turbo mode off to increase cpu ratio?

Another thing is the voltage, i set manual voltage to 1.040v, but inside windows running aida64 stress it jump to 1.141 to all cores, and when playing games or running sony vegas render it uses 1.090v what was using when it was set auto at stock, my 1.040v just is not accepted by MB?

If i put EIST off the cpu keep at max frequency and voltage always.

I just want to put at 3.9ghz or 4ghz with my voltage choice and with downclock 800mhz and downvolt working to save power when idle, and i just getting a bit lost to understand the way to go with it.

Thansk and sorry for my english. Hope this topic is right place to my doubts.
