Regards and sorry for my english

As inedenimadam mentioned running negative offset is completely fine. You have to use it in order to decrease your vcore but at certain multipliers a negative offset might make you idle vcore unstable.

The high negative offset that you have is normal for that multiplier. The negative offset will be less if you increase your multiplier, example im running a 46 multi w/ a -0.010 offset

Your idle and full load look great so good job thumb.gif

I followed this guide and have found that my temps are a little high. I'm wondering if I got a bad chip or if something else is wrong. Here is a screenshot after a one hour prime95 test at 4.2ghz with the offset to +0.005v and the Turbo Boost to +0.004v. I'm using a XIGMATEK Gaia for cooling.

http://i.imgur.com/ddqJq3T.png

I've found that when I go above 4.2ghz my vcore and temp quickly rise above 1.3v and 85C. Is this just my chips optimal overclock? If so, is there any advantage to increasing the turbo boost voltage?

Thanks so much for helping a overclocking newb.
post #7104 of 9531
Yes the advantage of Additional turbo is that it allows you to run a lower offset and lower idle vcore but this will be used more with higher multipliers. Usually you want your idle between .950-1.00v but some chips can go even lower.

If you are going to stick with a 42 multiplier then i would start bringing your idle & full load vcore down with a negative offset. See how low you can get your voltage before it becomes unstable.

You probably wont need additional turbo voltage with the 42 multiplier so you can leave it on Auto for now. You should be able to get both idle and full load stable with a negative offset.

I run my offset at -.020 and use my turbo boost to bring up my voltage. This was my chip still idles at the same voltages as stock.

I can't get my idle voltage between .950 and 1.0. I dropped to - .065v offset and even dropped the clock to 4.0ghz and it is still around 1.016... did I get a terrible chip?

dropping the multiplier wont help your idle voltage, put it back to your desired overclock. Keep going further negative. For 4.2 i can go down to -.120 before i start to get instability. just keep pushing lower til it wants to crash at idle/low usage(browser crashes and such) and then bring it back up a notch.

Hi,

So I followed the guide and now I have:

2500K @ 4.2GHz offset = -0.060V. Load @ ~1.288V and 68ºC.

And the rest:
Asrock Z77 Extreme4
GSKILL KIT 4GB DDR3 1600MHZ RIPJAW X (CL9)
CORSAIR CX-600W V2
EVGA GTX560 Ti FPB 1GB DDR5 PCI-E


I tried less than 1.288V with -0.065/70/75 at offset and when I did the 5 minute tests with Prime95 and played some BF4 Beta, all worked well. Then, out of nowhere, at idle, I get an BSOD saying 0x00(...)0124, so I did decrease step by step (0.005 by 0.005) and now I am waiting if it BSOD again with the offset @ -0.060V and load = ~1.288V and 68ºC.


This voltages are too low for 4.2GHz? What is causing the BSOD?

EDIT: Found this http://www.overclock.net/t/1120291/solving-fixing-bsod-124-on-sandybridge-read-op-first
Maybe this is my problem.. should I try disable the C3 and C6 report??

PS: Sorry my english, if you dont understand any part please let me know.

Thanks.

So I found a stable overclock. Running at 4.2ghz with an offset of -.100 and the turbo set to auto. It idles between .950v and 1.0v and never exceeds 1.2v or 70C. I may try to adjust to turbo offset to lower the load voltage a little more but overall I'm happy. Thanks for this guide and everyone's help!

As it turns out...I have found a shortcut to finding idle stability...

Laugh if you must...dont allow the system to sleep or even turn the monitor off, and play this game for 10+ minutes and then let it run itself open in the browser. cookie clicker
