The goal of tweaking this BIOS was certainly to gain maximum stable performance
. That value for me, may be very different for you. I know my GTX 980's are not silicon lottery so there's only so far they can be pushed (and therefore tested). I have also been doing ALL of my testing in SLI, where overclocking will always be limited to the weaker of the 2 cards. The OVERCLOCK itself and what some might consider "the maximum potential of this BIOS" will depend on the quality of your ASIC
I'm starting to really look at this BIOS as not only a performance benefit but also somewhat of a 'maintenance' update, improving upon stock in a few ways. I am also able to approximate the voltages based on my testing and reverse engineering. I DO have a DMM but I CAN'T get at the areas to get a reading but my method of reverse engineering really wasn't rocket science. It was basically hacking the BIOS, changing values, re-flash/re-test, see what happens, make notes, repeat...Let's look at some of the improvements over the stock BIOS:◄[ VOLTAGE ]►
In MSI-AB the following values will result in approximately:+00mV = 1.265V <-- reported in software (MAX OBTAINABLE with STOCK BIOS)
+20mV = 1.275V <-- reported in software
+40mV = 1.285V (1281.3V)
<-- still reports as 1.275V in software
It seems that these G1 cards max out at around 1281.3V. Attempting to raise the voltage any higher in the BIOS doesn't improve stability at all in fact it creates PERFCAPS. The VREGs are just not up to the job of anything higher. 1281.3V
is the max volts in the latest BIOS. So yes I believe that raising the slider from where I have it now at +40mV --> MAX will do nothing further but you are welcome to experiment, it won't hurt. The key benefit here is that you will be allowed to go a tick or two higher in voltage than stock, which I have confirmed improves overclocking slightly.◄[ POWER ]►
The G1's can provide plenty of power. There is no reason to handcuff the power, the voltage regulators already have them on.
Don't forget to prioritize on the temp and disable the link. This can lead to throttling on AIR.◄[ PERFCAP ]►
This is a nice little sensor in GPU-Z for maxwell tweaking because it will simply tell you where the restraints are (power, voltage regulators, sli, etc.). The latest G1 BIOS I am testing at full load is not triggering any PERFCAPS VERSION 3 BETA (Click to show)
As always, flash at your own risk. I will update the OP also.
Enjoy! ( ͡° ͜ʖ ͡°)
