HELP: Overclocking Titan X (maxwell) to 1500mhz, custom BIOS, unlock powerlimit

post #1 of 5

Hi guys,

Wondering if someone can assist me please.

I have the Titan X maxwell card, last year I installed a custom BIOS that had unlocked power limits, or atleast increased power limits to 125%, I overclocked it very well but could not keep the high overclock due to temperature issues. I now have installed a Corsair H115i water cooling unit with the adapter bracket, and the temperatures are perfect, with a 20% overclock to 1200mhz my temps can be around 40 degrees C.

The issue I have now, is that in MSI afterburner the power limit is locked to a maximum of 110%, and the most I can overclock the card to is 1200mhz without it freezing due to what I suspect is not enough power. I have tried the EVGA overclocking software but it also doesnt allow me to go past 110% on the power limit. I know for a big overclock like I want to I have to set between 120-125% power limit, with increased voltage, this should not be a problem now I have watercooling.

I have also edited the .cfg file for MSI afterburner and entered the EULA statement accepting the risks, etc, but still it only allows a 110% power limit.

Here is a screenshot that shows I am running the custom BIOS.

If anyone can assist with getting the software to show a higher available power limit then i'll owe you a cookie.

Thanks!

UPDATE:

OK problem solved!

It would appear the custom BIOS i was using had a power limit of 110%, I have now modified the BIOS to have a 130% power limit and reflashed it to the card, now the power limit slider has a limit of 130%. smile.gif

I have run a number of benchmarks without any problems. Core speed of 1500mhz confirmed by GPU-Z and Cuda-Z. Temps in the mid 50 degrees C with the H115i watercooler (with the pump speed on lowest setting).

Good results, and i'm glad it was a simple fix.

For info, i used the Maxwell BIOS Tweaker to create a custom BIOS, a used a modified version NVFlash that skips the official BIOS checking.thumb.gif

Update again smile.gif

I have finalised my overclock. Have settled with 1460 mhz on the GPU, and 7412 mhz on the memory. Ran numerous benchmarks all pushing the GPU to 100% load, and temps did not exceed 57 degrees C, this is with +100mv of voltage.

Watercooling this card is without a doubt the best thing you can do !!!

If anyone wants a copy of my custom BIOS then send me a message.

Heres a screenshot of my temps and clock speeds, can see its using 120% power limit, the most it went up to was 123% smile.gif

SO HAPPY WOOOOOO biggrin.gif

If your card isnt throtteling because of coming to close to the power limit everything is fine.If you start experiencing clocks below 1460 in some situations you should increase the power limit a bit more. btw. what is your limit in watts ? Having too much is better than too little.

Its not throttling at all, i decided on 1460 mhz purely for stability, 1500 mhz was on the edge. So far ive had a full night of gaming and not a single problem. Low temps and stable OC with a massive jump in FPS. smile.gif
