i5 2500k help?

post #1 of 17
Thread Starter 
I have the same sort of problem but it was running stable @ 4.3GHz so I put it to 4.5 then rebooted and then tried to run prime95 and it froze, pressed reset, same thing please help.
I have also tried to clear the cmos and it does not help. Does thins sound like a new i5 2500k for me or can i somehow fix this.

You probably didn't have enough vcore to run at 4.5GHz. Also, depending on your board, PLL Overvolt tends to cause the cold boot bug (which is what this thread is talking about).

When you first turn the computer on, and it turns right back off after about 2 seconds, but then turns back on tends to be a normal thing and is not a problem exactly.

I have never personally KILLED a CPU, overclocking or not. Well, I take that back, there was this one time with an Athlon XP where the fire department was called in...but we don't need to go there.....

Point being, I very highly doubt you killed the CPU. They're EXTREMELY tough to kill, even with a ton of voltage, heat, and other abuse.

you think my brand new GA-Z68X is faulty. I have had it running perfectly stable for the past 2 days. I am thinking maybe the RAM

The phase LEDs turn on but they alwasy turned on during the first few seconds of boot.

I have the GA-Z68X-UD3P and i have tried the CMOS reset so that should set it back to 3.3GHz. it has 12+2 VRMs so that should be plenty for 4.3GHz. Any other suggestions, RAM?

Try this....
  1. Unhook your power cord from the PSU.
  2. Press and hold your power button for 10-20 seconds (drain all power from the system).
  3. Remove the CMOS Battery from the board.
  4. Let it sit for 10-15 minutes or so.
  5. Plug power back in (but not the battery yet)
  6. Turn on computer, see if it POSTs.
  7. If it POSTs, repeat steps 1 and 2. Then put the battery back in, and turn the computer back on and enjoy.
  8. If it doesn't post, then there's a hardware problem somewhere. Maybe a reseat of the CPU, RAM, and GPU are in order at this point.

Unless you shoved some serious voltage into your equipment, I very highly doubt you killed anything. Worst case scenario, i'd say its the motherboard that died (if anything).

You could also try removing one stick of RAM (if it doesn't work, try the other), and see if it works that way too. Try the above steps first though.
