Hi, friends of KPC.
The reason we are doind this thread is to tell you about our "Titan's" experience, and also to alert the extreme overclockers to take care with the fragile Titan's PWM.
First of all, we tested the videocard in the air, and we were not happy to know the card coud not surpass 1175 Mhz / 1700 Mhz.
The videocard is a gift from Zotac Miami (very thanks to Zotac)... and since the videocard cost is about USD 2000 (or more) in Brazil, we noticed will be impossible to play SLI... and sure... 3 or 4 way.
Regardless all.... we decided to try to get the max of the card.

Phase 1 - Hardmodding

We did try the hardmodding (VGPU, VRAM and VPLL... also OCP and Thermal Shutdown)...
I often liked to make a control panel, to have easier acess to the trimpot and also measure points.
Looks like a functional and nice hardmod...





















Bad surprise

After we run 1345 Mhz... and get more than 18K on 3Dmark11, we (me and Schenckel) decided to put a lit bit more voltage... since we were under LN2...
So... suddenly, after 10 minutes benching and only about 10 seconds after start 3DMark11... videocard was death.
We measure the resistence and noticed the card was shorted.
OMG... to lose a VERY EXPENSIVE videocard in only a few minutes, was really a bad thing... but after to test the components, we could know that only one phase was death.




Still had a hope

Later that nigh in Brazil..... I see in the morning in Taiwan, ... TiN gave us a great help, and informed PWRGD point to cut... so, we could enable the Zoombie.
We started to hardmod again the card about 1:00 AM... and finally finished and tested the card about 6:00 AM... really tired out...
After to test and check it was working... its time to sleep 3 or 4 hours to finally try the Titan.

That's the result:

And that's the scores we got

We got World Global Record 3DMark Vantage and 2nd Global Record in 3DMark11.

http://hwbot.org/submission/2366237_rbuass_3dmark11___performance_geforce_gtx_titan_21017_marks






We know nothing compares with a magic hardmods done by TiN and Shammy... but we were happy that we made.
Unfortunately, LN2 is too expensive and we could not afford lots of LN2...
This is all we got with about 35 Lits...
Titan is a ferocious consumer of nitrogen... but bring us a lot of fun...

Best wishes from Brazil

Great scores, very nice!

What was the voltage on the dmm at the time of death? I don't have an untouchable...thinking.gif

The card worked 10 seconds with 1.46V...
It passed 1345 Mhz.... so, we increase voltage to try 3DMark11.
I suppose, to who don't want to zombified the card... do not pass 1.38...
I did not recommend.... because is REALLY a crap and weak phases.
Maybe you can run 1.4... or lit be more... but if I am you... do not surpass 1.38... is the max security I believe you can run (1.38V or less)

P.S. you can zoombified a Matrix, or even old good PWM cards

Thanks, I don't mind modding, but I paid too much for this card & it's been making me worry a bit seeing Vince & Andre doing all the zombie mods.

I'll be taking it a bit easier on mine.

I really do need to see about an untouchable, definitely came in handy for you!
