FX-8350 stability at 6.0 GHz

post #1 of 39
Thread Starter 
I am about to build a new rig, and was looking at some OC videos and saw that this processor currently holds the OC record at 8 and some change. I am new to overclocking but very used to building cooling systems. I wanted to know if anyone would consider it crazy to overclock one of these processors to run at 6GHz provided I keep it cool enough. I am always up for a challenge and wanted to know if anyone out there has done this and if so what motherboard was used and what kind of cooling they used. I am thinking of going with either a phase change or submersion but I haven't really seen anyone going this high just for gaming. I know it is completely overkill, but I really have nothing better to do so why not. Does anyone have any information on the subject?

Usually people can OC these to about 5ghz or high 4ghz on water.

I've heard they start getting fairly warm around 5GHz, but don't quote me.

I'm 99% certain though 6 GHz would be a huge challenge for a daily driver.

Not going to happen.

I run phase change and the highest validation on 2 cores that I've gotten on my FX is just a bit over 6ghz. The highest cinebench stable frequency at 1.6v has been 5.5GHz and the highest I can pass prime95 is 5.3GHz at 1.6v.

You're not going to even get close to 6ghz on any sort of 24/7 cooling solution.

I struggled to get even one pass of IBT at 5GHz. I had to have all my fans at max, and the windows open in the winter, with the outside air being channeled directly to the computer case, once this was done, I was able to get it to be about 47*C during IBT. But without the outsider air....forget it. Smokin'. devil.gif You'll be lucky to get a stable 5GHz without dry ice or LN2.

Well I know of personal friends who run stable at 4.5 with a simple water cooled system so I was curious how hard it would be to do. Clearly from the reply blasts it isn't going to be something done easily or at all. I see a lot of people running at 5 currently so I figured that adding a much more intense cooling system would allow me to surpass that pretty easily. This is more of a hobby for me because I have nothing better to do with my time. Would 5.5 be out of the question then? I just want to make some people go "OH ****" when they see it stable and I do enjoy the feeling of accomplishment that comes along with that.

As stated by alatar, he is running phase change and can't do it. Phase change is probably one of the most intense cooling solutions you can run 24/7.

Would I be better off trying this with a different processor? My thought process was that by starting with something that runs around 4GHz unaltered I would be much more likely to get results than with something at 3.2-3.8 range. I was also thinking of trying to do some kind of hybrid cooling to help dissipate the heat from the bottom of the board as well, seeing as cooling from both sides would be more effective.

On my FX 8350 I can get 4.96GHz stable...for whatever reason I cannot get 5 GHz 24/7 stable for folding or prime 95. Heat is not a problem for me...it is voltage, I am unwilling to go higher than 1.53-54 volts. That was even a little high for me. It's crazy how much more voltage it takes to go from 4.5 to 4.95.

PD chips are the best clockers for this, however you might be able to get 5.5 with a really good chip and a powerful phase change unit. An extra 100-200MHz maybe on Cascade. However the problem is that you're going to run into voltage issues, no matter how much cooling you give the chip you just can't run something like 1.7v on a 24/7 setup. The chip will die after a while, I just would not go above 1.6v for anything that's supposed to resemble a 24/7 setup.

And cooling the bottom of the mobo won't help at all. What you need all around the socket and the back of the mobo is insulation to prevent condensation from killing the setup.
