Is there any sort of benchmark or stability testing program that is more representative of the stress gaming would put on a processor?
I'm telling you right now 1.65volts is too extreme thee highest I would even dare doing is 1.53
I've been running 1.55v to 1.63v 24/7 for a few months. Temps usually in the 70s. I do a lot of rendering so my cores are constantly being stressed for extended periods of time at 100% usage while running AVX/SSE4/etc code.
Hasn't even degraded in performance or required any more volts after a few months. AMD 32nm is way, way tougher than Intel 32nm when it comes to taking abuse, and 22nm compared to AMD 32nm when it comes to take abuse isn't even in the same league. AMD can easily take what Intel can't, when the Intel would degrade and stop working and the AMD would just scream "YOLO SWAG MORE VCORE YO"
And yes, it does have a thermal kill switch at 90c, found that out the hard way.
But my point is that these chips are very, very tough and you shouldn't have to worry too much about damaging your chips. Yeah, you are taking a risk going this high and I wouldn't hold AMD responsible for any damage that does happen, but look how many people in this thread have degraded their chips.
Heck, I even started off in this thread saying I"m going past 1.55vcore and I don't care, I'll just buy another chip. And I"m still on my 1236 I bought at release.
People seem to be too worried about the size of the process node and not how the node was actually made. AMD has FD-SOI which can take a beating but is larger. Intel has 3d which is smaller but if you ran IB or Haswell at 1.6v 24/7, disaster would probably strike very quickly.
I only recall seeing one person run their 22nm Intel at 1.5v+. They delidded, talked a bunch of smack, then disappeared in what I can only assume to be a dead CPU. Meanwhile the AMD section is full of people running 1.55v+ for months.
TL;DR: Yes, it's risky running 1.55v+ but it seems pretty safe so far. 1.55v+ is fine, just make sure you have enough money for a new FX if worst comes to worst.
