Newbie Overclocker Looking for Guidance

post #1 of 5
Thread Starter 
Hey guys, I've been a long time browser of Overclock.net and it's helped me troubleshoot many problems I've had with my past computers. I've been building computers for well over a decade, however, this is my first attempt at overclocking, and like the thread title says, I'm in need of guidance.

I have an ASUS Maximus IV Extreme and an Intel i7-2600K, and I'd really like to get the best possible results without going over 75c. Unfortunately, I'm not running a Water Cooling setup, so I splurged on the next best thing and got a Noctua NH-D14.

My issue right now is that while I've read several overclocking guides for beginners and know the basics, I can't make heads or tail of Maximus's BIOS Settings, and what I personally need to change. I know I won't be able to hit 5.0 GHz if I want to stay below 75c on load, so I'm shooting for 4.8. I'm just not sure if my CPU can reach it and what settings I have to change in order to try. So I figure I'll just list the options that look important and whether I should change them or not.

Default Settings:

Ai Overclock Tuner: Manual
BCLK/PCIE Frequency: 100.0
Turbo Ratio: All Cores mode (Adjustable in OS)
Maximus Turbo Ratio Setting: Auto - I assume that needs to be 48.
Internal PLL Overvoltage: Auto
Memory Frequency: Auto
Memory Bandwidth Booster: Disabled
EPU Power Saving Mode: Disabled
DRAM Timing Control: Auto - Default Speed for my Ram is 9-9-9-24-2T, I'd like to see 9-9-9-24-1T
GPU.DIMM POST: Auto
CPU Performance Settings: Auto
Extreme OV: Disabled
CPU Manual Voltage: Auto (I have no idea at what setting I need to start but I figure v1.35, correct me if I'm wrong)
DRAM Voltage: Auto (It's currently set at 1.647 with Auto Settings, but RAM specs say it needs to be v1.5, so should I change that?)
VCCSA Voltage: Auto
VCCIO Voltage: Auto
CPU PPL Voltage: Auto
PCH Voltage: Auto
PCH PLL Voltage: Auto
NF200 Voltage: Auto
Skew Driving Voltage: Auto
CPU Spread Spectrum: Auto

CPU Settings:

CPU Ratio: Auto
Intel Adaptive Thermal Monitor: Enabled
Limit CPUID Maximum: Disabled
Execute Disable Bit: Enabled
Intel Virtualization Technology: Disabled
Enhanced Intel SpeedStep Technology: Enabled
Turbo Mode: Enabled
CPU C1E: Auto
CPU C3 Report: Auto
CPU C6 Report: Auto

I have the CPU ID that came with Maximus IV Extreme, Prime95, MemTest 86+, RealTemp, and EVGA Precision all installed to monitor what its doing to my system. I also have AI Suite II installed which should tell me whats going on with Voltages.

This will be a Gaming PC, I currently have no plans on Folding. So I don't imagine my CPU will ever be as stressed as it becomes during a Prime95 run.

I'd appreciate any help and input on this... I know I'm asking for a lot so I hope those of you who decide to help me can bare with me.

I need to get some sleep, but I'll try to give you a few tips before I log off.

The first thing I noticed is that you should change your DRAM voltage asap. In my experience, increasing it that high with 1.5V RAM can actually cause it to be less stable (my 1.5V RAM just won't work right at 1.6+, but I can OC it from 1600MHz to 1866MHz at stock voltage). VCCIO of around 1.1v can help, too.

75C max under load is a good number to shoot for. When most people say this, they are referring to the max temp they hit under a long Prime95 burn... but, keep in mind that IBT/LinX with AVX will generate considerably higher temps. If you're hitting 75C in Prime95, it's possible your IBT temps could hit 85C, or higher. Just a heads-up. It's up to you whether you want to shoot for 75C in Prime95, or 75C in IBT. In "real world" usage I doubt you'd ever go over 60 or 65C if you topped out at 75C in Prime95. Right now, I am topping out at around 66C in Prime95 and 77C in IBT.

As for settings the CPU voltage, a lot of people like to use the "Offset" setting on this board. It will keep your vcore very low while idle, but it will increase when under load. You'll have to experiment to see what works for you, since all CPUs are different...but for me, something like +0.100 with LLC on Medium works very well around 4.7GHz. You really should test it out on your own though, start low and work your way up to stability.

Lastly, reducing your CPU PLL can decrease your temps for sure. Some people go down to 1.75... but I am able to get down to 1.71 and remain stable. I haven't seen many people advocating this low of CPU PPL voltage, but it works for me.

Anyway, time to hit the hay. I hope this helps.

scroll down until you see my bios settings, these settings are good for a 4.8ish OC for most chips , give or take a few voltages up or down. 1.40-1.42 for extremely average chips is usually required, if you are lucky you can run it at the sub 1.4 voltage spectrum.

I appreciate the response guys. Using offset I was able to get 4.6 GHz at v1.28 with HT Enabled. It also idles at v0.944. I'm sure its stable after running Prime95 Blend for 8 Hours with no errors.

I was able to get 4.7 GHz at v1.32 but the temps would sky rocket to 87 C (Ambient Room Temp 32 C). Once I replace my air conditioner I may try for 4.7 GHz again and see if I get decent temps to run it 24/7.

Offset Voltage: -0.60
Load Line Calibration: Medium
Phase Control: Standard
VRM Frequency: 350
CPU PLL Voltage: v1.72 (Reduces to 1.715 when running OS)
Memory Frequency: 1600 MHz
Memory Timings: 9-9-9-24-1T

Since you're all so knowledgeable, I was wondering if you could tell me what my chances are of running into the dreaded CPU Degradation I've been reading so much about? Is it inevitable for every CPU thats overclocked, or only for those at High Voltages? Highest Voltage I got on the CPU was 1.45 for a few seconds because I had no idea +.100 Offset would give me that. I restarted as soon as I checked the voltage and brought it back down little by little to v1.34 before trying to find the lowest voltage at the speed I wanted.

As for degradation , there is no proof out right now since the chips are only a few months old.
People have been using 1.5v since launch of these chips with no problems, i haven't seen a single thread where someone has burned up one of these chips. I myself have taken my chip up to dang near 100c, and have not seen any problems at all with my current OC of 4.5 @ 1.310v.

Here , there is a lot of useful information , muna is a great dude if you have questions http://www.overclock.net/intel-cpus/968053-official-sandy-stable-club-post-your.html
