Well before I Overclocked my Intel 2500k to 4.7GHz, then I was upgrading parts and reset my BIOS. I re-Overclocked to 4.7GHz and now once a day my computer will crash.
Now it doesn't crash during Gaming or Rendering or anything, just doing simple things like watching Netflix. I can go into my Bios and get all my settings but I'm wondering what may be causing this issue.
I believe I followed this guide, but am at x47 & +0.050Volts.
Ok. I have the same mobo and CPU as you, and this is a 4.5ghz setting 100% stable.
Of course, if you so desire 4.0ghz, you should be able to leave everything at Default, and just change the CPU multiplier
CPU Multiplier x45
Short and Long duration: 230/200.
core current limit 200
Vcore: OFFSET mode +0.020Volts
Load line calibration: LEVEL 4
Spread spectrum disabled
Everything else leave auto.
max temps i get is 58C...H80 cooler. With a 212 expect like mid 60s
Everyone has a different 2500k, so test the voltage first. You might need higher or lower, but this is what worked successfully for me.
Don't forget to select a best answer!
CPUs differ among themselves depending upon from where the die was cut from the wafer. Some will perform better than others.
For your CPU 4.7 GHz seems too high and is causing instability. Lower the OC to 4.5 GHz and run it at the lowest voltage at which the CPU is stable. When it crashes, up the voltage a little bit (0.010V) - as always, closely monitor the temps.
I understand that, but what would cause it to become unstable? As it was previously.
It probably was not as previously stable as you thought, most don't want to take the voltage to where it really needs to be to reach solid stability and you're using offset voltage settings anyway, according to what you've posted.
Offset voltage settings will allow a certain level of fluctuation which may have been just enough to cause your crashes.
Personally I use fixed voltage which brings more heat to be dissipated, but stops operating system fluctuations that can cause a crash, if the rest of your settings also work together to use fixed voltage in the first place.
When you said, "you followed this guide", it looks more like you followed someone elses suggestions?, which is really the best way to get into trouble, simply because what works for one may absolutely not work for someone else.
You may very well have followed a suggestion given to you by someone that was barely stable themselves.
If you want to follow a Guide, Here's one! (But make sure you have a good CPU cooling solution!)
Additionally regarding the 2500K an overclock past 4500mhz is really not necessary, especially if you are air cooling, it doesn't bring enough extra performance to the table to justify the extra voltage and heat to reach the multipliers above 45x.
Personally I would be the last person here to limit you past a simple caution, so whatever your goals are just remember you get there one step at a time.
Ok people I need a help too!!! Does anyone know how to overclock intel E5200 2.5 Ghz on asrock g41c-gs motherboard.I have tried everything but when I change fsb on my cpu just for a little bit my computer restarts it self after short time. Please help !!!
