Trying to understand what's going on...

post #1 of 5
Thread Starter 
Been attempting to overclock my i3 540 for the past few days and not understanding why I'm having random crashes. I'm not going anything crazy but I'm currently at 3.6Ghz and every "appears" to be ok. Windows runs fine but every once in awhile, while listening to music or having a video game run play a video (like opening credits or whatever you want to call that), it'll freeze for only milliseconds but enough to notice it. If I leave everything at stock, it's fine.

The problem is, it's not static. It doesn't happen always. P95 runs for hours on end, temps never break 67C and that was me trying to get my cpu to 4 ghz.

I haven't really been messing around with voltages (just multipliers for cpu + ram) though and I'm wondering if that's what my problem is?

Other specs are 4GB of DDR3-1600 ram, Gigabyte H55M-S2V, HD 5770, Win 64. I have the Cooler Master Hyper212 Plus for the CPU plus 2 case fans that are providing air directly on it. I don't think heat is my issue cause like I said, the hottest I ever saw was 67C in realtemp and that was hours in p95.

So any advice would be great. You're safe to assume that I'm running stock voltage. Oh and I've never had BSOD or any other errors in windows. When I tried 4ghz but just changing multipliers, I had games lock it up though (freeze and sound looping).

Thanks for the help guys - krarks

You probably aren't stable. Stress test with LinX and Prime95. If they fail (your system BSODs), raise your voltages and try again. Overclocking is a long process of trial and error.

Well I have been running p95 for hours and nothing happens. It runs fine without BSOD. It wasn't until I stopped running P95 and tried playing a game that I noticed anything was up...but if you think that I should keep running stress tests than I'll definitely do that.

Should I be adjusting voltages or is that only required if things are stable at all?

Do BSOD when you're playing a game? Or does your screen just go black.

Are your voltages on auto, or have you set them manually to "stock"?

Also, have you overclocked your GPU at all?

Haven't touch the GPU clocks and the voltages are at auto. If I open up CPU-Z I can watch then vcore voltage move from 1.1v to 1.4v Idles at 1.1v

And no haven't had a BSOD ever and I only had a game completely freeze when I was running at 4 ghz. Just went black, sound looping. Went to restart, didn't recognize keyboard or boot windows which made fixing the BIOS hard and had to remove CMOS battery to fix it. Although P95 didn't show any errors at 4ghz and temp's were completely ok, that still happened.

Like I said, I'm currently at 3.6Ghz, things have been okay except I was listening to music and surfing the net and the sound froze for what seemed like milliseconds. Then I loaded up STALKER and the opening videos were doing the same thing. Gameplay wasn't affected though. Everything is working fine at the moment. Been running this OC for over 24 hours too. This is why it's so odd.

I've experimented with OC'ing video cards and almost always the only time anything bad happened was when temps got too hot...seems things have changed since then haha.
