Either I was unlucky, or these chips are more fragile than is commonly accepted. I thought 1.26v was safe given how many people are running 1.3v or higher (even >1.4v for the XS folks), but apparently not.
A few weeks ago I began getting the typical "clock interrupt not received on a secondary processor" BSoD, so I backed off my OC. Did this until I was at 4Ghz @ 1.18v, but earlier today it happened again. Pretty sure the CPU is well on its way to failing outright.
For technical details I'm running a 3x140mm radiator with an Apogee XT and MCP655, and a GTX 480 in the same loop. My 24/7 settings were 4.2Ghz @ 1.26v, with full system load temps varying between 60-75c due to room temps. Idle was in the 30's. Was one of the horrible launch day batches as the chip maxed out at 4.3Ghz with 1.3vcore, didn't like the temps so I backed off to the above settings.
I'm no stranger to overclocking... my first chip was a 2.8Ghz Northwood that I ran up to 3.4Ghz for years. That 10 year old system still worked perfectly right up until I sold it this year. Upgraded in 2006 to a launch day E6300, which I ran at a 100% OC (3.8Ghz) for 24/7 folding@home purposes for a few years. That chip never degraded an iota and is still in use as my father's PC with a mild 3Ghz air OC on it.
Out of the dozen chips I've OC'd this is the first I've ever personally had degrade, and it's only four months old!
