what gpu are you using?

Holy crap 4,7 GHz on a 920 drool.gif Even if its not prime95 rock solid its still an amazing achievement. Most 920 top out at 4,3-4,4 GHz and even then they need massive amounts of voltage and cooling.

This guy is nowhere near stable though, it couldn't take 20 minutes of light usage from an 8 year old game.

Which part of the motherboard gets hot as a result of QPI/Vtt Voltage being high? I noticed that Flight Sim ran a lot longer at 4.7ghz when the computer was started at 4.7ghz cold than when i started it hot after I had been playing around with it for some hours. Any ideas what would happen, if as an experiment I ran the mains cold water supply through the CPU block just as an experiment? Avoiding getting condensation of course.

GTX 580. I have 2 of them but for FSX I have SLI disabled

I never really got my 975 past 4.4 stable in any stress tester, though if I had pushed the voltage to 1.55 I think I could have run 4.6 stable in ordinary workloads.

I runs well at 4.6ghz. most likely I will stick with 21x221 or 222

The max I overclocked mine was to 4200MHz. It was only experimental and for benchmarking purposes.

Thanks for the kind words and encouragement. Again this morning starting from cold I ran the PC at 4.7GHZ and it ran FSX with demanding addons with all graphics setting to maximum in FSX and the addons producing by the way 10 fps in vitual cockpit view and 20 fps in external views over Hong Kong. The sim ran for 25 mins before BSOD 0x124. I know that this doesn't mean much to Overclocking purists but FSX is a real practical application of Overclocking. This software simply will not deliver without Overclocking the system substantially.

Anyway see below bios setting for 4.7ghz. I think that this is the sweet spot for the Vcore and QPI/VTT for this overclock because its runs longer at these setting than any other that I have tried.

So it would seem now that since I am going to wait a year before I get new hardware beefing up my cooling is the only option. I have been thinking about a DIY option and here it is:

I plan to pick up a used dehumidifier and cut a hole in the side placing my Koolance radiator behind the evaporator hence having very cold air flow over the radiator. Since my computer is in a very small room with a drain in the floor the dehumidifier will also have the effect of drying the air in the room reducing condensation on cold surfaces. And to reduce condensation even further inside the case Push and pull fans will be passing volumes of the now dry air in the room throught the case quickly soaking up any condensation that may occur. And finally the combination of the controls on the dehumidifier and the coolant pump should give reasonable control over the system?

Has anybody tried this?

that 1.6v vcore is a little scary. I don't think I would be comfortable with that 24/7
