Not sure what happened. Ideas?

Concerning the system in my sig. I have had this chip OC'd for months with no issues. Yesterday I had to reboot and during the post I noticed after the "Verifying DMI pool.." it popped up a "MBR error 3" notice but booted into W7 just fine. It skipped the Acronis true Image recover tool option. (Hit F11 to access.)

So I Googled the error and discovered it's a known issue with Acronis TI. (Something about them moving there data to the MBR instead of their own "Secure zone".)

Anyway, I started my 2 F@H clients, and it froze within 5 minutes. It did this 2 more times, so I went in and redid the OC fresh. It froze 2-3 more times after that while folding.

So I uninstalled TI, and the MBR error 3 still popped up. So I reinstalled TI, and it then started offering the recovery option again.

It then froze one more time.

I have been folding for 12+ hours since without a freeze.

Any ideas on what the heck happened? Does MBR have anything to do with OCing? I mean, it still booted into Windows, and everything "mild" worked fine. It only froze after starting the F@H clients.

If you can help shed some light it would be much appreciated. It just seems odd it would go flaky after a couple months of solid use over a simple reboot.

(Though I know PCs can be quirky in this manner. I just like to understand the ins and outs if possible.)
 
Well, for the sake of closure, I'll update my lonely thread.

I managed to sort out the MBR issue as mentioned and have yet to see it again. I left the True Image Secure Zone intact with the recover manager enabled but uninstalled everything else from Windows.

I am pleased I managed to get back my 3.65Ghz OC, though I had to bump the vcore to 1.4675. I ran IBT for 10 runs on High (Lacking the RAM for Maximum.) with flying colours. CPU-Z is reporting 1.36-1.4 while folding with temps between 58-60C. (Fans running at 1000 RPM of their 1500 max.) It's been going all night without a hitch.

Still not sure why the OC lasted for months then decided the vcore was simply not enough, but I'm happy it's were I was hoping to be when I bought this new mobo a few months back.

Now it's time to try and push my 5870 to 1000/1300.

P.S.

Well, with a northbridge/RAM voltage bump I am currently F@H at 3.74. :) It crashed without those bumps at 3.74.

I just put a brand new HX850 in a few weeks back.

It seems to be dealt with though. I have been folding both CPU/GPU (GPU wants 1 core to itself.) at 3.8 for over an hour with no issues. I had to bump the vcore up quite a bit. I also bumped the RAM to 2.0v instead 1.8, and the northbrigde went from 1.1 to 1.2. It passed a 10 run ITB, but failed when F@H on an earlier, lighter OC. So I now use F@H as my stability test. :D

All seems stable so far, and I couldn't be more pleased. I wanted 3.8 when I first got this chip but was leery of going too high on the voltage tweaks. I finally said screw it and it's at 1.47xx in the BIOS, but reads 1.408 max in CPU-Z.
 
Over time, overclocks components suffer electron migration and other factors (heat, etc.) and need a little more juice to keep them going at what they used to do easily before.
 
I completely forgot about that. I read about it long ago when I first tried OCing my P4. (I've got a terrible memory until reminded.) It was extremely mild on a stock cooler. I think it may have even been part of why I waited until the last 8 months or so to really dive into OCing. Afraid I'd mess something up.

My 3.8 OC is still F@H without issue. I think I can call it stable at this point. Joy. :cool:

Thanks for the reminder. I like to know why things do what they do. This was confusing with the Acronis True Image issue happening right when the OC went to pot. It makes perfect sense now. Nice to know they were not related.
 
Wow, I'm impressed. I bumped the FSB to 3.9 and have been folding for 45 minutes without issue. This is a C1 revision to, not the better E0.

Temps reach 65C at times (Did with 3.8 to. It's at 60-61C with the window open.) and the CPU fan is almost fully maxed out. (120RPM left till maxed out.) I'm surprised the RAM has held out to. It's running at 918Mhz with 5-5-5-18 timings.

Man, this is getting addictive. :D

P.S.

With a bit more juice to NB/DDR2/vcore, I'm currently folding at 4.0. :eek:

Though I am several hours from calling it stable.

Click to expand...

After over 15 years of overclocking, I have yet to see this happen on even one CPU, stick of RAM, or video card.

The only thing I notice is that it is not as easy during the warmer months to hold the same overclock.... but that is glaringly obvious.
