Trouble Overclocking 2600k with ECS p67h2-a2

post #1 of 6
Thread Starter 
I have a 2600k and an ECS p67h2-a2 motherboard. And i want to overclock the 2600k a bit, see if i can get another year or two of use out of it, or at least convince myself to wait long enough for more motherboards to come out for Ryzen and for Intel's next gen. Unfortunately it isn't the most user friendly bios. I eventually found the CPU multiplier and set it to 40 and disabled turbo mode, but using cpu-z and HWMonitor, i never see the clock rate go above 3392 when stress testing it. When I later go into the bios, the multiplier is still set to 40, so it isn't being reset. Any ideas what could be preventing it from going above 3392?

in that article for overclocking it says "There are no auto-OC options. You’re forced to navigate through several menus to get to the CPU multiplier options—here I upped the multiplier to 40, left the voltage on Auto, and rebooted into Windows. This worked without a hitch and on full load"

i'm like, i hate the author.

I have CPU Ratio at 40, I set IA core Current to Max, just in case that was causing it, Set power limit to 180 Watts to make sure there wasn't causing it, vcore is as 1.25 and i disabled EIST. And it won't go above 3.4Ghz. I don't know why. If i set the multiplyer to 30, it will underclock. But i can't overclock. Its driving me crazy trying to find it.

Auto OCs are usually not stable over the long haul and push volts too high. You want to OC manually, albeit it seems that it's giving you some difficulty. When I overclocked my current rig I had to take into account 17 of the settings on the Bios. The higher the overclock, the more fine tuning you will need to do.

Here is an example:

01. Ai Overclock Tuner => XMP Profile
02. Asus Multicore Enhancement => Disable
03. CPU Core Ratio => 46
04. Min. CPU Cache Ratio => 40
05. Max. CPU Cache Ratio => 40
06. DRAM Frequency => 2400MHz
07. Timings => 10 -11 -11 - 28 - T1 - 1.65v
08. CPU Current Capacity (in DIGI+ Power Control) => 130%
09. DRAM Current Capacity (in DIGI+ Power Control) => 130%
10. LLC => Level 7
11. CPU Core Voltage Override => 1.345v
12. CPU Cache Voltage => 1.25v
13. CPU System Agent Voltage => 1.25v
14. CPU Analog I/O Voltage => 1.25v
15. CPU Digital I/O Voltage => 1.25v
16. Eventual CPU Input Voltage => 1.9v
17. CPU Spread Spectrum => Disable

I'd start by reading a guide on your CPU and perhaps if you're lucky you might have an OC guide on your CPU and mobo combo.

Get familiar with what each of the setting means and does. This way, you can make connections between the settings and reason out a solution.

ok, i finally got it to go above 3.4ghz! It looks like I have to enable EIST and do it through turbo mode with this motherboard. I had tried it before, but i'm guessing something else like the power limit was holding it back when i initially tried it.
-edit oh, nope, looks like the probably when i tried it with turbo mode first might of been setting the default clock multiplier to something above 3.4, if you do that turbo mode doesn't work.

So my vcore isn't very stable. I set it to 1.4v and it bounces up to 1.44v at seemingly random times. Except when i'm stress testing, it never goes above 1.4V... 1.45v is the limit i'm comfortable raising the voltage to, but with it spiking to 1.44 when i have it set to 1.4, i'm stuck at 1.4v. Also when i'm in the BIOS, it shows the vcore fluctuating between 1.272 and 1.284V. I'm wondering if perhaps EIST and or Turbo mode could be causing this. Or if there is any other ideas on what could be causing this fluctuation. If EIST or Turbo mode could be causing this, I'm curious if anyone has any idea on what could be preventing me from overclocking outside of EIST and Turbo Mode.
