2500k Trying to get 5ghz stable.

post #1 of 24
Thread Starter 
Hey guys. I've been trying to get my 2500k stable at 5ghz today and am not having much luck. I've been messing with the settings and just ran prime95 for a an hour and 45 minutes and I got the 124 BSOD. Here's some pictures of my bios settings smile.gif

I just changed the PLL from 1.62 to 1.55 because I heard of some people having luck lowering it, and it relates with my 124 bsod. Any other suggestions? Also, the voltage fluctuates from about 1.48-1.496 volts. It mainly stays at 1.488 though.

You may just need more voltage, not all can hit 5 without a boat load of voltage. How much voltage did you need for 4.8?

Ok..a)turn turbo OFF :thinking.gif: Why does your bios look different than mine?
I use 1502
hmm..try setting vccio to 1.12-1.16
And as for that pll lowering stuff..Hogwash.Set it to around 1.77-1.845

Whynot use manual mode instead offset and step up in hundredths for stable and then switch to offset. I stopped at 1.475 becuase I was getting 81C on air from Prime95 5 seconds after starting and at 12 seconds I BSOD'd at 91C. NEED MOAR AIR.

VCCIO = 1.1
CPU PLL 1.7

What options you got for LLC other then medium? im not so familiar with Asrock BIOS, but im pretty sure the first 2 suggestions might help!

This and try these also, seemed to work with my benching 5GHz oc.
LLC: High or Ultra High
CPU Current Capability: 100%
Duty Control: T.Probe

If it does not help I'm afraid you will need more vcore. Keep your turbo on however unlike what that guy said.

Having actually reached 5GHz with a 2600K, that advice isn't the best.

There's no reason to disable Turbo. That has been proven to have no effect on an OC's stability.

For my processor, I had to lower my PLL voltage to 1.625 in order to get it to work. At higher PLL voltage, I was unable to get my computer to stress for more than a few hours. Given the high variability in the different voltage settings required to reach a stable 5GHz, I strongly recommend that you test each and every PLL voltage setting. It's time consuming and a pain in the ass, but I would never have reach stability if I hadn't. Both of the settings +/- one step are not as stable as 1.625 on my mobo at 5GHz.

I agree with the VCCIO voltage recommendation, but again, what you're looking for is stability, not voltage overload. More volts =/= more stability. In fact, your stability problems might be because you are putting too much volts in right now. Not necessarily that it is the solution, but that it might be.

If you haven't, head over to the so-called "know it all" munaim's Sandy Stable Club (see sig link). Other than totally not being a know-it-all, Munaim's generous advice helped me (and countless others) get to a stable OC.

The hard forum guide isn't bad, but to follow it blindly wouldn't have given me the results I got. Like I said, there's a lot of settings that each have a lot of options, so read all the advice you can get, and figure out what works for your CPU. Unfortunately, there isn't a one-size-fits-all solution, and not all processors can do 5GHz stably. If you have questions about any OC settings, the Sandy Stable Club thread is a great place to ask.

Oh..like I've never reached 5ghz? :kookoo.gif Stable? SB is boring.I'm going to quote someone and reiterate"Even a monkey can OC Sandy Bridge."

The reason my bios looks different than yours Schmuckley is because I just got the newest bios update that came out this week, and it's a different text.

Also it took me 1.440v to get 4.8 stable. I've been messing with my case and just got my h100 into a push/ pull config so my temps will be lower! Thanks for the input guys i'll try out your suggestions!

I've tried other Bioses..prefer 1502
Aside from the vcore reading being off..IMO it's the best
