Need gpu recommendations for 7680x1440p - Page 6

post #51 of 52
yeah you will get 3-4-5 years insteed of more then 10 in some case , but if you believe it has zero impact you need to go learn about electricity and semi conductors ,......
you can like to oc without being complitely blind and not willing to say that it s not free perf ,.... otherwise it s just called bad will

Yes you've read the theory but seem short on practice. Overclocking "can" have an effect on semiconductor life but::

1. Not at the voltages we are using
2. Not at the temps we limit our overclocks to
3. Not within the useful life of the equipment.

As an analogy, at our office coffee machine, we have a quart of "Half and Half". No it's not refrigerated .... we prefer it at room temp because it makes the coffee tool cold when left in the fridge. Now, reading the books you would tell me that dairy products need to be refrigerated or they go bad. And yes, that is true..... at our office temperature of 65C (50ish at night) , it would prolly start to go bad on the 3rd day or so..... but since the carton is empty before the end of a single day, this really is not a real concern.

At the end of 3-4 years, we've cycled our PC's ..... CAD boxes after about 18 months are handed down to engineers who don't need that much performance on a regular basis as the CAD guys. When that happens, the clerical staff gets what the engineers had. The kid used to wind up with the ones displaced from the clerical staff but now they build their own boxes. Since we opened the business over 20 years ago..... we have never had an equipment failure of a CPU, MoBo or GFX card .... just opticals and HDs which are unaffected by OCing.

Semiconductor life is greatly affected by voltage, both the amount and consistency, as well as temperatures.

a) We use only top end, jonnyguru performance rated PSU with rock solid voltage stability, far less than the 5% allowed by the ATX standard (typically < 1%). MoBos are selected which have high end capacitors, chokes and strong multi-phase voltage regulation..... GPUs are selected which have custom PCBs and beefier VRMs than reference models.....all in all , voltage is very stable with no wide fluctuations.

b) We do not use extreme voltages..... the type of degradation you are referring to therefore NEVER occurs. We don't have CPUs running at 1.5, 1.6, 1.7 volts..... we top out at 1.4....and that's under P95 ..... never see that under CAD or gaming.

c) We use only high end cooling solutions.....We do not allow CPUs to reach anywhere near Tmax.....highest one we have hits 75-76 under P95....again never see during every day use. No GFX card exceeds 82-84C .... and that again, only under extreme torture testing.

Simply put, while it's theoretically possible to damage semiconductors by overclocking, it's simply not realistic to suggest that it is a danger under the conditions which we are overclocking..... This fact is borne out by the length of service we have been getting out of our builds which are still functional when we give them away.....and we give them away because it is not cost effective to use them in a production environment and no one in the SOHO wants them (SO = small office / HO = Home) after 3-4 years. On top of that we build for colleagues, clients and whomever and every box that goes out the door is OC'd....since we have been in business, we never had a machine fry anything ... again other than a HD or optical.

So whiel your concerns are certainly within the realm of possibility in the world of "overclocking", the conditions in which we are conducting our overclocks just make such an expectation completely unrealistic.....a fact borne out by the 0% failure rate.
