Overclocking 2500K

Just thought I'd post here and update you all

I was reading online and found out that because I had my computer in the 'High Performance' power setting, speedstep was disabled, so I was constantly running at 4GHz

I have now set it to balanced so speedstep is enabled and this time when I booted the PC it did not cold boot even once, it worked properly first time

Could it maybe have been that it was something to do with speedstep being disabled that caused it to cold boot?
 
just to set your mind at ease, the sandybridge cpus, were pretty much designed to be overclocked so dont worry to much about voiding any warranty, aslong as you dont put you cpu vcore above 1.4 you will be fine as this is was intel state as the safe limit
 
azibux i have the same board as you just few days ago. I too looked into overclocking and followed a video on youtube but like you when i set overclock to manual i get the multiplier greyed out and unable to change it.

How did you manage to change the multiplier?

OK, thanks for that info :)

Where the multiplier is it will say 'auto', you then click on that and type the number in. Is that what you're doing?

Also you have to have turbo mode (setting is in CPU config, next tab along from AI Tweaker) switched on, and have turbo ratio set to all cores

Let me know if you are still stuck and I will try to help :)

EDIT: Also, here is a link to my other thread, post 14 shows a picture and gives a bit of an explanation :)

I've yet to try and look again but i remember trying before when first got the board and when i clicked the multipliers it was grey and i could enter a value (eg 45) but when i would click off it would return to 'Auto' again.
However i will check again and see if Turbo is turned on and if that then allows me to edit the multiplier setting and then go from there (very unsure about what to do with voltages and other settings so will probably be back for advice)

As a side question if i tinker with these settings and things go wrong how do i set the bios back to 'factory default' setting, i see there is a option to run 'optimised' but no kind of failsafe or default setting

I've left the voltage on mine as it was, because I didn't want to mess around with that, and I don't think you need to up the voltage unless you are going for a higher overclock

I think maybe removing the CMOS battery and bridging the correct jumper pins will reset it but I'm not sure on that. Maybe someone can confirm?
 
Hi,

I just tried to run IBT on maximum but it causes core temp to stop responding (so I can't properly monitor the temperatures), it starts responding again when I stop IBT or when it is finished, then it shows what the max temperatures were but I don't really want to run it 10 times on maximum and then find out the temperature it reached afterwards, I want to monitor it at the same time so I can see if it is getting too high.

This also happened when running IBT on standard, but then it didn't really matter as I knew it wasn't going to get too hot anyway

So, what other software can I use to monitor the temps reliably?


Hope you can help, :)


EDIT: I did run it on maximum, 1 run, but I didn't let it finish as I couldn't see the temps properly, the highest temperature one of the cores reached was 74 celsius, is that OK? What temperature is too high?

download CPUID hardware monitor and use that instead

Thanks, just downloaded it, will let you know the temp results from running IBT on max, 10 times once I've done it (might be tomorrow) :)

Also, what temp should I stop the test at if it gets too high? What is too high?



Thanks for your help, :)
 
My chip reached 75 deg celcius when running IBT, just finished a 15x run just now that lasted for 2 hours, I'm happy with that temp, don't know about others. What cooler are you using?
sorry I just read your sig, so you use Tranquilo? Would you mind posting your temps as I'm considering that cooler for my 2nd computer.

I can't run Burn Test on Maximum, it uses all my RAM up and then I get a bluescreen lol, runs fine on Very High though, any idea why?

That's because it's not stable enough, you need to up the vcore or lower the multiplier. Don't go over 1.425v or 80C when running IBT. And about 1.38v max vcore and 70C for 24/7 use.

Running IBT on standard is a waste of time, it won't stress the CPU enough ;)

If you set it to Maximum it will use all the available ram (but if a background process kicks in, it will force it to use the page file, which will slow it down to a snail pace)

The best way is to do it is either set IBT to maximum, see how much memory it will use, then switch to custom and set the memory to about 200mb lower than the max setting.

Or the way I do it is to open CPU-Z, core temp and a browser (Chrome). Then open IBT and set to maximum, then close the browser, which will give you some free memory. Then run IBT and take a screenshot halfway through the last run.

Thanks for the info,

There are some temps on the first page of this thread, and I will post the temps after running IBT after I've done it

Also just for info, @ 4GHz, I am just web browsing and the current core temps are mide 30's except for core 2 which for some reason is 42. Should I reseat the cooler as the paste may not have spread correctly over core 2?

Thanks for all that info, will help a lot :)

Will let you know how I get on :D
 
Here's a screenshot for reference, this is my 24/7 OC. Max temp for everyday usage inc games is around 50C and that's with all my fans on silent :D
