Hi Forum, Just wanted to share my overclocking experience with my card, and see if you can explain what I am seeing. When I am overclocking with a slider, I can do +115 clock and get to 2085-2100 MHz, but I am seeing that voltage max out to around 1062 mV with the voltage slider dragged to 100%. However, if I use curve OC in after burner with force max voltage at 1093 mV, I am able to do +190 clock and get to 2175 MHz max. Fire strike url (3dmark.com/fs/20518703) I think I got lucky with a good card, but not sure if you guys would agree. https://www.3dmark.com/fs/20518703 Curious to know why with the default slider overclock, I cannot push my voltage up and achieve the same result with a voltage curve? In addition, anyone know how I can smooth out my voltage curve after I found my max offset? Would be great if someone can link a guide. Thanks edit by Cool GTX added link for OP

how did you forced higher voltage?
both with afterburner and x1 I am getting around 1.050-1.060v and stuck under voltage limit, while powerlimit is ok.

Interesting technique there. The slider just shifts the normal clock curve up and down, with your radical change to the shape of the curve you may be tricking Boost 4.0 to allow more aggressive ramping into the high voltage and clock points. The card is very comfortable at below 2000mhz at 1.050v, so maybe its just driving deep into the curve. But who knows.

You can lock voltage to max with guide in forums.evga.com/Guide-How-to-force-max-voltage-amp-curve-overclock-with-msi-afterburner-m2820280.aspx
I tried downloading Precision X1 v1.0, getting same result with lower voltage.

How are you controlling the 3 fans on your GPU ? Afterburner can't - from what I've read in many posts Same Results ? Is that Same Performance ?

I got it!
If there is flat curve for your freq/voltage - system uses less voltage for desired frequency.
And difference (step) between frequencies must be 15mhz.
And default curve is flat from 1050 to 1100mv. I just added another two steps and now my max voltage is 1087mv as desired.

I cannot control 3 fans in Afterburner. I turned them to 100% in X1 first, and then switch to afterburner to control the voltage. Same as the voltage max out to 1063 with X1 1.0, cannot find a way to push to 1093

Ahhh I may not know much about this, but I did the same for about ~6 months or so about?
Locked to 1093mv voltage and could stay locked to 2205mhz. Card supposedly 'degraded' within that time and cannot hit higher than 2100mhz anymore with crashing, some games won't run anymore unless I dial it back to +50mhz on Core w/ just the voltage slider (SotTR, Control).
Kinda regret doing it now as slider OC would hit ~2135-2150 on +135 Core.
Just in-case my guy :)
Kind regards!

Did you replace your paste / TIM when you got the performance drop? PSU wearing out? Heatsink clogged with dust?

Decent score, but see if you can push 19K in Firestrike Extreme.

Brand new PSU, heatsink, fans all given a good clean and I repasted too! To be quite honest the changes occurred after a W10 automated update bricked my PC causing it to fail to boot. Since I re-formatted, it couldn't hit the same clocks lmao. I tried to re-install the same drivers I had too hahaha. Who knows? :)
