September 26, 201213 yr I run about 1.5V for stability @ 4.9GHz on my chip with 2.6GHz RAM. Voltage does kill chips, but temperatures are a good indicator of how safe a given voltage is. If you can run IBT @ 90 C or less, you're probably OK.
September 26, 201213 yr I tried, hotest core was 93c. In fsx i have max 69c at 5GHz. 4.9 seems to be much safe, well I'll think about it. Thanks Zeljko Budovic
September 30, 201213 yr Author Looks like I have a MB issue. Core temp is reading 60-70C while the motherboard utility monitor is giving me 100C. Maybe that's why the throttling happens. Which one do I believe? Bert dela Merced

September 30, 201213 yr Author I did not de-lid. Just artic silver for the thermal paste. Bert dela Merced
September 30, 201213 yr There's your problem. Overclocking Ivy hits a brick wall at 4.4-4.6GHz unless you de-lid.
October 1, 201213 yr Author It was a MB problem. Just switched MB and started a Prime95 test. So far so good at 1 hour. All temps looking very good no throttling so far. Bert dela Merced
October 9, 201213 yr Author I'd like to thank everyone for their input in this matter. It was in fact a motherboard sensor problem that caused all my throttling problems. Currently, I'm running at 4.7Ghz with 1.345 (CPU-Z) Core voltage very stable. I'm very happy the way FSX is running at the moment. :Big Grin: I did hit the proverbial "wall" of Ivy Bridge. At 4.8 I can get it stable but 100C temps spikes during stress tests scares the hell out of me. I'll quit the overclock for now and enjoy FSX. Again, thanks to everyone. Bert dela Merced

October 9, 201213 yr Author Did you de-lid? It's really not all that hard and it will drastically improve temperatures. Not yet. I will do it down the road, but in the meantime, I'm enjoying what I have. :Big Grin: Bert dela Merced
October 9, 201213 yr Not yet. I will do it down the road, but in the meantime, I'm enjoying what I have. :Big Grin: Those extreme temps could potentially expedite the electromigration process. I would recommend de-lidding asap...
