I have a new ASRock Z77 extreme4, does the OP or anyone know what primary plane current limit and secondary plane current limit are? They are the only options I do not see listed.

I was in the dark too, until someone pointed out that if you overclock, both primary and secondary plane current limit should be the same or higher as your Long duration power limit & Short duration power limit.
Don't really know what they do though, but I've set all of the four settings mentioned above to 150 and running good for now. thumb.gif

Alright I followed this guide which has the long and short durations at 500. I used the same values and so far so good.
Thanks!

how do some people make their i5 3570ks clock to 4.5 GHz using only less than 1.2 volts? that is what i'm trying to achieve
post #506 of 9487
after updating my boards BIOS to the latest v2.10, it seems that the XMP no longer works. tsk! mad.gif

im using the AsRock Pro3-M. the previous BIOS was working fine w/ the XMP settings. i can even OC the ram to 1866mhz fine!

now i cant even touch any settings that includes my ram cuz the board will just not keep any settings saved.

i can overclock the procie fine w/ the new BIOS but when i touch anything on the ram settings, the board goes crazy and puts everything back to default. doh.gif
post #507 of 9487
Thank you for this guide. I used all the same settings, except enabled Internal PLL Overvoltage. I have an i7 2700k, Asrock Z68 Extreme 3 Gen 3 MB, 16 GB (4x4) Kingston Hyper-X DDR3-1600 (1.65V) RAM, and a CoolerMaster Hyper 212+.

I can run 4.8 GHz at a +0.125 offset. That gives me a vcore of around 1.36V (as reported in CPU-Z). It's been running Prime95 stable for about 1 hour. The thing that concerns me is the heat. Load values are in the high 80s - low 90s. Is this expected for 1.36V?

Anything I can do to lower the heat? Or is this the best that can be expected on air?

I think they are just lucky ;p. I don't need much voltage at all to achieve 4.4 ghz, but suddenly for 4.5 ghz I need an offset of +0.05/0.055 range which is 1.285V and resutls in temps in the high 70s under load and 36C idle. At +0.05 offset, Prime95 blend was stable for over 5 hours, but Crysis 2 in DX11 ultra did crash to desktop after about 30 minutes of playing, although that could also be the video card overclock. My 7970 was stable at 1250mV on my old motherboard, but the new Z77 motherboard I need closer to 1293mV for some odd reason.

I haven't really found a stable 4.6ghz setting because I would probably need a 2nd smaller radiator for my water cooling setup (single EX360 for CPU and 7970 video card), as temps were in the low 80s under load with 1.36V.

To try to make things cooler, I turned down CPU PLL, but that just seemed to result in instability when turned off of Auto.

Those seem like high temps for a vcore of 1.28+. I'm running at 45 with an offset of 0.015 and running prime I'm only in the low 60s, and that's on air (CM 212 Hyper). What's your cooling?

Edit - I'm going to add that the ambient temp here is still pretty cool, in the mid 60s Fahrenheit, so that could be a factor.

other people tend to use fixed rather than offset (negative) to lower the Vcore. which is better?
