Similar to AMD O/Clocking? Plus wonder if you guys can help me out, i switched from an AMD setup/windows and upon boot up with the new i5, sometimes it brings up a message, failure to load or something, then says about the cpu may have been overclocked or overvolted, press any key to continue. any ideas
Would be useful if we could have the exact error message, however K-series overclocking is pretty straight forward (like AMD black edition) overclocking on most motherboards as you usually just need to change the CPU multi and maybe bump up CPU core and CPU VTT voltages a little.
When you oc a i5 2500k, you set the turbo boost multi, so that when the chip is under load, the chip boosts it's clock to 4.5+ ghz (100*45). Just like Uxon said, it is alot like the AMD BE chips when you leave cool and quiet on.
The random message I get upon booting the pc is: Not sure if this has any thing to do with it, but I forgot to connect one molex from the H80, started up the system but checked CPU Temp in bios and it was 85c because there was no cooler. Would this have damaged the CPU? it was only on for no more than 2 mins.
Possibly, depending what temperature it actually reached and how long it stayed there. Have you changed any settings in BIOS at all?
I doubt the chip is badly damaged....though you were sailing close to the wind...... I don't have tons of SB experience but I always found it to be a bit random in booting with an OC. Maybe a voltage is too low?
When I overclocked my CPU, the max voltage I put through it was 1.35v Now this happily hit 4.5ghz and at one point his 5ghz but now it just wont get there. BSOD's above 4.5ghz. I don't OC anymore I did it just to see if I could. I don't need that extra CPU grunt. And what people have said before is correct. Increase the Turbo Multiplier to achieve the OverClock.
I've noticed that with mine; 1st few times, mine would hit 4.8Ghz @1.45V (crappy chip) Now it struggles with 4.5Ghz @ the same voltage. Now I just leave it at stock as all the games i play rarely push it. I'm actually contemplating going back to my trusty AMD rig as that was never really pushed but is alot quieter (water cooled). I wonder if we're seeing chip degrading at a quicker rate due the higher voltage to transistor size ratio?
Ived changed the multipler a few times now but wont save the settings when I get to desktop for some reason. I dont have a turbo multipler just a normal one ?
Not sure with Gigabyte Mobo's bit with Asus it's the turbo multiplier that's changed. And as to why the settings aren't being saved i don't know why either.
I reset the cmos battery and saved new settings but under "my computer" the changed settings are not taking effect, maybe I am not changing something else?

hi CPU-Z is showing updated settings of OC but mycomputer is'nt is this a reliable indicator of this?
Haha, ignore my computer. Just use cpu-z. SB is easy enough, up the multi, when it's no longer stable, up the vcore, then up the multi again and so on
Just done 3.7ghz on stock vcore, ran IBT for 10 packs @ very high (5gb ram), max temps were 61c but average was around 56/7c and found to be stable. any issues with temps?
You sure? just did the same test on 3.9 and more or less the same story with max temps reaching 64c but not for more than a minute then decreasing again
56c isn't great for 3.7ghz with a liquid cooler. Does the cooler have good thermal paste? Did you touch the thermal pad or cpu surface with your finger which may have contaminated it? Is the cooler fitted properly (screws tightened assuming it uses those). The other thing is if your H80 rad is sucking air from inside computer case, that will be pre-heated air. Heated by the GPU, Ram and PWM, what is the airflow like in your case?
its at 4ghz now and idle temps are: cores 1-4 (31/29/32/33). The H80 is using air from within the case and the case is a Raven RV02, I might change to a push pull config. I didnt have much thermal paste left and only applied what I had, as for touching the CPU, the surface?
