Over Clocking limitations or lotery?

[Mick Naughty]

So dove into oc'ing my 1080's again as I don't use them much lately. When I got them I assumed they would be the same aside form bios and lottery of course.

 

If on stock settings, your card hit the voltage limit because of gpu boost that wouldn't effect stability correct? But when you start to over clock that would be an issue.

So I assume its a bios setting as my cards are both reference pcb's. Though I haven't looked into both bio's im just going ona whim at the moment.

This is the EVGA SC stock, usage and power fluctuate as this is heaven running. Voltage pegged. Would also hit power limit every once in a while. With max voltage it stays at 2000 with no oc.

 

Max oc I could get to be stable in heaven.

 

This is a stock dell/NVidia referb. Friend got a deal on 40 of them, so I figured id give it a try. Maxing out the voltage and power does nothing more for this boost wise.

 

Max oc I could get stable in heaven. Never raised the voltage or hit the limit.

 

 

Obviously not having fans the power limit being raised do much except for the SC slightly.

 

So this all cant be lottery as far as the voltage goes. Not gonna shunt the power but ill check out the bios's later. The whole NVidia using the "best" components on their boards contribute or should I throw this all up to lottery?

 

Just hate running them sli as I though the sc was down clocking itself but as it turns out its the weaker of the two.
