DELL M18X A03 BIOS THROTTLE REMOVAL GTX580M SLI

[barcode]

So no fix for he 580M but perhaps if it is a driver then you could try older drivers?

Currently working on getting a set of older drivers to work to test, no luck yet!

Also since its not a temp throttle on my side of things, its the nvida overvolt protection (ovp) thats kicking in when running furmark etc at 0.92v.
I have requested a volt mod of 0.90v to be done and test since stock is max 0.87v. (Maybe the 0.92v was way too high and it was triggering the ovp) Mvktech has not responded yet to my request, unless i figure out how to mod a vbios file from 0.87v max to 0.90v, i suppose i can do it myself.

Stock volt of 0.87v max overclock is 724mhz all stable (compared to stock 620mhz) which is still roughly 20% overclock with no trigger of any throttle in furmark occt etc.

Basically as Ahmed said if its not throttling in games i think we should all be happy this is just nvidia protection which im probably happy to have.

But if any further developments or updates arise i'll update

Personally i feel the sweet spot will be 0.90v without triggering the ovp in furmark etc and will be able to get at least 800mhz stable

We will check again, though from our first analysis there are no in between values as the GeForce GTX 580M and lower all have some predefined voltage levels which can only be selected but none can be added, which is not like the desktop series but complete the same as the previous GeForce GTX 4x0M versions. Now we will recheck but I am quite confident there will not be something else, and for those who are playing with the voltage table to set some voltage like 0.90V or 1.00V, that won't make any difference as the voltage table only sets the label not the actual voltage as we explained multiple times before
