Last night out of pure bordem , i decided to overclock my 2500k.
after watching a few youtube tutorials, it seems fairly straight forward
so i went ahead and set the clock to 4.5ghz and the voltage to 1.350v
i then installed prime95 and left that running overnight for about 10 hours
all seemed good, there was no errors in prime 95 and i thought id cracked it.
been playing farcry 3 no all day with no issues at all.
but i just been watching a blu ray dvd when i got blue screen of death, the pc has started back up and has not crashed again since typing this.
my specs are
TOWER CASE: Corsair Obsidan 650D
Processor: i5 2500k
COOLER: Corsair H100
MOTHERBOARD: P8z68-v PRO
MEMORY: 16GB Corsair Vengeance
GRAPHICS CARD: Palit Jetstream GTX 670 2GB
SOLID STATE DRIVE (SSD): Corsair Neutron 120GB
HARD DRIVE (HDD) :Samsung Spinpoint F3 1000GB
POWER SUPPLY: Corsair TX850
Drive: Samsung Blu-ray
just want to know if its possible the blue screen of death was caused by the overclock, even though it passed a 10 hour prime95 stress test, also is there any way to default the overclock back to factory speed.
any help appreciated thanks
0x124, ok, you can go higher as long as your under 80c after hours of stress testing no prob. What voltage does the CID auto adjust too if you leave it on auto instead of manual adjusting if you plug in a 43x or 44x? Is it stable at one of those? Have you changed any other voltages maunally, even except maybe ram voltage? Do you have your 1333 ram set with the XMP profile to 1600? That can change ram voltage to 1.65 and qpi/vtt to 1.2 sometimes.
- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU
- Aim to keep temperatures below 75c underload if at all possible
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
Testing Stability: Intel Burn Test - Overclock Stability Testing ( 10-20 Loops Maximum) THEN run 8-12 hours of Prime95 on blend.
I personally recommend overclocking through the turbo and not the base clock ratio. As overclocking the turbo seems to be the most stable for the chip.
Below should give you an idea as to where you should start at Vcore wise for each overclock you attempt. I usually start on the high end of things, then drop it down .01 after each successful Intel Burn Test.
