Asrock z68 extreme4 auto overclock - good info?

post #1 of 10
Thread Starter 
So I wanted to find a starting point for overclocking my 2600k. This is the first time I have ever tried to overclock anything. Well, since I'm a noob, I let the mobo's bios do it for me. I have a Asrock z68 extreme4 mobo. I autoverclocked it to 4.8 on the ratio (only thing I changed). I was able to make 5 passes on IBT and 8 threads on very high setting. Everything passed okay.

However, my vcore was about 1.401 at the max and my temp about 84c. I want to keep the 4.8 but try and lower the heat and the vcore.

A few questions. First off, is the above what I really want to do or are those okay? I'm happy at 4.8 24/7 if possible. I want to be able to leave my cpu at this clock. I'm idling at 26-31c and its 70f in here. Any problem leaving this clock?

Do I need to lookout for anything else that is dangerous? There are alot of other voltages, do those matter? Such as: +5.0v voltage, dram voltage, vtt voltage, vccsa voltage, +3.3voltage and more.

What should my max be on my vcore and heat? I'm thinking 1.38v and 80C? Does that sound good or too high? I know this is highly subjective...

Lastly, what do I do to start downing my voltages manually and so that my mobo's bios doesn't try to override my settings?

Any help would be greatly appreciated....thanks everyone!

Not sure if I have a specific answer for you, but I have the same MB and have used those settings. Do you know if the auto OC changes anything but the multiplier? I'm trying to keep it at 4.4GHz for longevity's sake.

Yes, when you change the "Load Optimized CPU" setting to 4.6 or 4.8 or whatever, it changes other things automatically. HOwever, my computer wasn't really stable at 4.8. Are you sure yours is stable at 4.4? I found out that my system may have passed IBT fine, but definitely not Prime95. I started Prime95 and everything was fine. I started running the test and then stopped them and exited out of the program to check something. I turned Realtemp on and then opened up Prime95 again and it crashed to a BSOD immediately. It seems like P95 never crashes when running, only when opening the program. Don't know if this is normal?

Also, not sure where I go from here? Did I get any valuable info from the auto OC...other than I need to bump my vcore up? There are just so many options in the OC Tweaker section of my UEFI that I have no idea what can/should be adjusted and what shouldn't.

Also, do my fans automatically increase in RPM's as needed depending on the heat?

I don't plan to go over 1.3V...it was stable in Prime95 at 4.4GHz...I didn't run it for an extremely long time either though. It was also stable in IBT. I compared benchmarks to the stock clock and I definitely noticed an increase in performance at 4.4GHz in the finite element modeling software I use. I'm not an expert at overclocking, as this was my first attempt as well...

I have the P67 Extreme4 and i5. I highly recommend starting at 4.4~4.6 range if you haven't done OC before.
Getting to 4.8 on a first try is a bit tough unless your chip is a great one.
Since 4.4~4.6 is relatively easy to get for most of the SB.
If you make those stable and you'll probably familiarise yourself with what other voltages affect your OCability.
Since usually to make 4.8 above stable, you need to tweak settings other than vcore.
Which means you need to know what other voltages do.
Higher the clock, it gets harder for RAM to keep up also.
Stuff like that you'll know by doing it.

LinX or IBT is good for short stress test that quickly tells you your setting will BSOD or not.
But the true stress testing is to run Prime95 blend test for at least 10+ hours.
Less than that don't make your system stable (at least to me. since prime95 starts the intense work load at 8~10 hours into the test.)

I hope this helps a little.

Thanks for the info. I'll try starting at 4.6, my question is, what settings need to be adjusted so that the mobo's UEFI doesn't try to auto correct my settings or throttle my clocks? There are all kinds of things like Internal PLL, Spread Spectrum, etc and a whole bunch of other things. When I tried to manually set my vcore and cpu clock before, the settings didn't take....

Turn "Spread Spectrum" OFF. It'll make your BCLK to 100 even.
So you'll see exact or just above the right GHz. (if it's ON, you'll see 4.59 even set it at 4.60) It is actually made for minimizing the internal electrically intermittent noise getting to your on-board sound.
So if it is off, you might hear the squeaking noise when the CPU's on load from your on-board sound out, though.

I have most of my Power saving feature ON. Except the main "Power Saving Mode", "Thermal throttling" OFF.
Other settings helps you lowering your electric bill.
And usually won't affect stability of OC. (unless you are going for 5GHz... 5.0 or above is a whole another game...)

VTT(VCCIO) is a internal memory controller voltage. It affects RAM OC.
Do not change VCCSA. That is a system agent voltage which shouldn't be touched.

Internal PLL overvoltage is a required feature if you are going above 4.6GHz.
You may turn it on if you are going for 4.6 now.

CPU PLL Voltage amounts varies between set up.
Mines needs to be up at default value (mines at 1.832).
Some MB and RAM set up don't require high voltage so some people turn it down to 1.709.
So you have to find out what's best for your system.
But this setting is more likely to be touched at last resort.

Less voltage = less heat. That is the general idea.

For getting to 4.6 you probably don't need to change anything except vcore to make it stable. Unless you really want to minimize the heat.

All the systems acts differently so you have to figure out what your system acts with OC.
Even having exactly same components, copying somebody else's setting usually WON'T work. (99% don't work)

OC takes time and patience. That is the way it is.

Thanks Tuna, I'll try those suggestions. I have found some really elaborate guides for the 2600k but for other motherboards. Are the features in the UEFI always the same regardless of the mobo?

Similar. But in different terms. (VTT in asrock, most of other MB call it VCCIO. and stuff like that) Z68 MB has graphics option since there is an on board intel graphics.
