neede advice on my 2600k overclock.

post #1 of 6
Thread Starter 
currently I have my 2600k at 4.6ghz. I want to push it to 4.8-5.0 but I have some concerns about voltage. I am running on a P8p67 board and followed basic setup instrictions from this guide
http://www.overclock.net/intel-gener...uide-p67a.html

dissables what it said to in that guide. runing auto voltage I am showing 1.42 at idle droping to 1.38 under p95 load with 25% load line calibration right now and the computer is stable. The issue that I am wondering about is that when i up the multi to 47 or 48 the idle voltage is like 1.48 and i am concerned about running that voltage. My cooler seems to be doing fine and my temps under p95 are right at 70-73 or so. I have seen guides that say 1.52 is ok but I am not used to pushing so much voltage into a cpu and the 1155 chips are so very differant to overclock. I am wondering which voltages to trust. I tried to set voltage manualy just to check some setting and I have to set it like .08 volts higher than it shows on pc moniter in bios or CPU-z. I got the computer to boot to windows at 4.8 at 1.45v but it BSOD as soon as I started P95. this may have been my load line setting that caused it though.

also I have heard that you should disable some setting in the bios which I have done for the moment while I try to get a stable 4.8
C1E-DISABLE
EIST-DISABLE
C3, C6 States-DISABLE
CPU Thermal Monitor-DISABLE
Load line Calibration +25%

so to sum up my main point of interest.

what voltages are normal to see in cpu-z at a 4.8 or 5.0 clock and why are mine higher than others that are also using auto voltage. should I just switch to manual like I'm used to and up the load line a notch?

I would like a stable 4.8 at least before I start in on my ram settings.

A good chip will require around 1.4v to hit 5.0GHz. This is a very GOOD chip. You may or may not need more, depending on your chip's need for voltage. 1.5v is not uncommon for a 5.0GHz overclock. Intel's maximum voltage spec for the 2600K is 1.52v, so if you don't go above that, you're perfectly fine.

I have a different mobo than you, however my vcore goes up with my LLC on lvl 2 (highest) This helped me achieve stability. As for vcore, I was just pushing to 100x50 and I decided to stop at 1.470vcore (bios) as CPU-z was reporting 1.500 vcore under load. That is as high as I felt like taking my vcore.

My stability @x50 was about 3 hours of Bad company 2 before x124 bsod.
Upping LLC really really helped me, so I would sugest playing with it a bit.

I would recommend leaving C1 and the others on, also EIST. Unless the chip runs unstable with them on.
If possible. Disable things such as floppy, lpt and other types of connections you dont use. Use offset, -0.010 and 48x multi.
If that works, great!

Offset seems to work for most. Having that x16 multiplier at idle and a low vcore is good for the chip, I suppose

Ok so I spent some time on the overclock today and have it stable at 4.8
Setting vcore to 1.465 I'n bios was as low as I could go without bsod. I'n CPU-z it's reading 1.44-1.46 volts and I have LLC set so the voltage remains solid under load. It dose seem odd to me that it wanted that much voltage to stabilize. I thought I could do it on less voltage since many others have no problem doing 4.8 on a lot less. As a result my heat under prolonged p95 testing is I'n the mid 80s with idle at 40 ish.

Playing world of tanks it never got over 60 on core 1 and the rest where cooler at 48-55

In volume 1 datasheet page 78

The processor works SAFELY from .25v to 1.52v MAX.

Logically keep it at 80% don't push it to a full 1.52v

I checked out over 12 forums...and they were all wrong about overclocking
and some even BS about it.

So I got fed up and talked DIRECTLY with Intel engineers and read there pdf books on there products.

and signed up with this site to help you........mmm something I rarely do.
