[Review] Skinneelabs CPU Block Roundup #3 Results Database

[Vapor]

You might also consider some sort of "Overclock Potential" bar chart. Gabe notes it takes 10C to see a 1.5-2% overclock gain.

If we are seeing at most 9 degrees from best to worst, that's only 1.5%

So if you ran the GT at 4000Mhz, the best block would afford you 4060Mhz??

I think that helps put things into a more bottom line Mhz perspective.

Or if someone currently has a HK and they are thinking of "Upgrading" to the AC Kros....the difference is 2.2 degrees or .38%. 4000MHz-->4015MHz

IMHO, while temperature is something we all THINK we understand because everyone has the ability to measure....I don't think people really understand what temperature means to overclock.

Some sort of simple bar chart showing OVERCLOCK in MHZ would be a good way of speaking a common language to a larger audience.

That would be a big mess

And I just don't have applicable data for how this CPU, let alone any CPU, scales with temperature.

I may be way out of line here, but from my own, very poorly done tests. some blocks seem to scale better than others as CPU output rises. I know this would be a very exhaustive test to perform and Vapor needs a new CPU that will overclock higher to do it. lol
It would be a very interesting test.. unless I have too many variables, and poor testing methods, and that is what is causing the scaling to be different?

If I were to have a second test setting, it would be at lower settings. 4GHz at 1.5v (measured via DMM....CPUz says 1.55v) on a D0 (this chip was also binned from a selection of 5 as the hottest of the group) is about as hot as I can reliably do. Surely I'm already causing degradation at this kind of voltage and this why clocks are only at 4GHz--I want the chip to have a moderately long life so that I don't have to keep breaking test continuity. 4.4GHz at 1.4v isn't as hot or as stable as 4GHz at 1.5v.

That said, I have no intention of doubling my workload for data that doesn't add much value.
