Can't get past 4.6ghz 2600k but temps are good

post #1 of 12
Thread Starter 
So i've been trying to get past 4.6ghz on my 2600k but having a really hard time. Here are the settings i changed. Everything else is at default/auto.

BLCK Freq. - 100.0
Multiplier - 46x
PLL Overvoltage - disabled
Load Line Calibration - High
VRM Frequency - 350
Phase Control - Extreme
Duty Control - Extreme
CPU voltage is on Offset Mode
CPU Offset is +0.055
DRam Voltage is manual 9-9-9-24 and 1.5v (16GB RIpjaws 1600mhz)
Speedstep, Turbo Mode, C1/3/6 - Enabled

I've done quite a bit of research with my first overclock but still a noob i guess. Although it seems like everyone's stable voltages vary greatly i feel like i'm either missing something or just have a really crappy chip. I'm showing 1.4v under load running IBT maximum stress. I felt like 1.4v would've been enough for 4.7ghz or even 4.8ghz but i guess not. Any suggestions on other settings to try or change?

Your settings look good to me initially, although i keep my PLL voltage at default. Anyway, two questions:

1) What temps are the cores seeing before it crashes?
2) What error are you getting when it crashes out mate?

Disable C3 and C6 when using offset and see if that helps you out any.

Also, if you can't boot into windows period above 4.6 you need to enable PLL overvoltage.

Hey sorry for the late response i was away for a few days. I'll try enabling PLL overvoltage the next time and disabled c3/6. I think the max temp on any single core was 69 celsius. Cooler is a Phanteks PH-TC14PE and i would think it'd be able to handle 4.7-4.8ghz but maybe i'm wrong and need to go to water. When it freezes up the bsod only pops up for a second then it shuts down. I got so many bsod's from tweaking settings that i actually had to clear the cmos battery to get it to boot again. I hope i'm not doing any permanent damage. Everything i've done has been within reason (volts, settings, temps) based on the research i've been doing.

question, what are the c1, c3 and c6 for?

I think it has something to do with power management at idle, or the idle "state". When i get home i'm going to try disabling C3 and 6 but what exactly would that do? I'm going the offset mode route because i don't want 1.4v on the cpu at all times.

enable PLL overvoltage, had to do it to get over 4.6 myself.

Yeah that's the first thing i'm going to try. Been doing some more research and now i'm learning that disabling C3 and C6 will lower my HDD/SSD speeds? Wouldn't that defeat the whole purpose of oc'ing? I'm assuming having lower read/write speeds would slow the system down even if i'm getting an extra .1-.2ghz on all cores?

It wont lower them it will raise them. Not sure if you mis-read article or if article was wrong.
