Degradation may occur at even the slightest overclock however you may never really ever notice it, it will most likely reduce the life of your chip by a year or two, and buy the time your anywhere even remotely close to using up the life on your chip you would have already upgraded to something different.

I wouldnt worry about it too much, I have heard of people running 1.5v with no immediate degradation, I believe only the C0 revision chips had real problems with that. As long as your stable and your temps are good 1.3625 is fine for 24/7 use.

Thanks Matt, I was debating whether to stay at 4.2 or tone it back down to 3.8 @ 1.25 stock voltage since it's not likely that 400mhz is going to make any difference playing games at 1680x1050 + resolution anyways. But I think I'll stick with 4.2Ghz as it will give me an excuse to upgrade if it ever dies .. hahaha (not that I need to with the 3 PCs I have)

You would actually be surprised at what such a minimal seeming OC can actually do in gaming. I noticed over a 1000 point difference in 3Dmark06 going from 4.037 to 4.275GHz on my E8500. Gained about 20 fps in the Half-Life 2: Lost Coast hardware stress test as well (I know it's old but still)

Yea I've seen some people with a different approach (over-volting mobo) to achieve a similar OC with lower VCore. But when I look at those numbers of 1.4V+ MCH and VTT etc, it scares me a bit as those number look way out of spec; I rather have everything stay in spec and push a little more VCore than to do that, but that is me

darklink

I hear ya. I took the other approach simply because my motherboard cost less to replace than my CPU so if it craps out on me, I can still save a few bucks over replacing the CPU. Plus I am also trying to run the lowest Performance Level setting as possible so I had to push my NB voltage to 1.36. It's okay tho, I got a Thermalright HR-05 IFX/SLI cooler on it with a 80mm Panaflo attached to it so it stays nice and cool

*sigh* I'm running into problem again.

After stress testing for 10 hours OCCT, I settled with those settings expecting a relatively stable machine. But I remember the system having problem when I after I unplug and plug it in last time I took it to the lan party, I tried to unplug it while I was at home.

I plugged the power back in, and everything started up fine at 4.2Ghz, so I thought it was just a one time problem. But when I tried to start folding@home (GPU client with GTX 260) I started getting BSOD hours into the folding. My rig was folding stable for at least a day the last time I tried, before I did the unplug/pluging power cable test.

If you're familiar with nVidia GPU folding, my CPU load was at less than 10% at the time of the crash. Do I have a bad video card or is it possible that the OC was not stable after all (I downclocked it back to 4Ghz in the mean time and will see if folding crashes it again)

Any ideas and suggestion are appreciated!

I dont remember where I read it but I heard of the gigabyte boards doing things like this, I dont know why a loss of power would cause instability.

Folding is more GPU intensive than it is cpu intensive, and you mentioned very early on that you didnt start having these problems until you changed from an HD4870 to a GTX260.

Re-evaluating the situation I thought that maybe your PSU couldnt keep up and was somehow causing an instability issue, but then I realized that you have a corsair 650tx psu which is more than enough for the GTX260.

Now im thinking that maybe your gpu is causing and maybe has been contributing to instability the whole time. Obviously your voltages and settings needed some tweaking but you should be golden with what your at. What drivers are you running for your GTX260? And more importantly what was the BSOD you got, the description of the screen.

I'm running the latest nVidia driver 185.85, and unfortunately I wasn't able to read that BSOD message before it restarted my computer.

I understand overclocking can be a frustrating process, but it is discouraging to see my rig BSOD'ing even passing 10 hours of OCCT.

I'm running out of ideas

Mattb2e

Try reverting back to an older WHQL driver, im running 182.50 and havent had a single problem yet.
