2500k OC stuck with a blinking cursor

post #1 of 7
Thread Starter 
Hello,

I've been trying to OC my following setup:
ASRock P67 Extreme4 (newest bios)
2500K
Elixir 4GB DDR3-1333

I can get it stable at 4.2GHz with the turbo or my own settings. However at 4.3 the comp freezes quickly and at that 4.4 onwards I just get a blinking cursor before Windows should boot. It doesn't matter how much I up vcore, it just hangs there each time. I've disabled the power saving options, spread sprectum and tried PPL overvoltage on/off. Am I stuck with a CPU that simply doesn't go any higher?

I had this same problem would not post past 45x for the first couple of days and I ranted on here like crazy. Anyways short story It would not boot at 46x or 47x also 48x so said ok this sucks tried 50x and it booted right in. I'm not sure why but now I can boot at all of these no problems at all. So I would try at 50x at like 1.45 volts see if it boots worth a try.

Hey, thanks for replying. I actually found out the same. I tried 49x just to test it and got into Windows load screen. Didn't get very far though but I decreased the multi to 44x aftwerwards. I got into Windows and ran Prime 95 for a short while. Things seemed good. However I can't get the system to cold boot. If I shut down the computer fully, wait for a moment and start up again it's stuck at the blinking cursor once more. I read about the exact same problem in another forum and the fault there was the CPU. Unfortunately I can't really test it out.

For how long?

How long I ran Prime? Just half an hour. I understand the system might not be stable but it seems a bit odd to me why it wouldn't let me boot into Windows after a cold start even with a unstable clock since it had done that a moment ago.

No, how long does the cursor blink for? I should have been clear. It could just be applying the setting each time it boots? Did you alter any voltages? Your RAM might not be getting enough power. BTW I'm guesstimating some troubleshooting options that I ask myself when OC'ing. biggrin.gif

I actually ran into this when I updated my BIOS from a very stable 4.7GHz OC.

I fixed it by clearing the CMOS, removing the battery, waiting five minutes, replacing the battery, and then clearing the CMOS again. I re-applied the exact same BIOS settings that I had before and it worked just fine, and was stable. (In fact, it wasn't until after the BIOS update that I did my 18+ hour Prime95 stable run to test it.)

It doesn't hurt to check.
