EVGA 1080 Overclocking

Definitely moving in the right direction here; this round Classified owners have really had a hard time and it is a true breath of fresh air to see someone out there who cares :-)

now...Only had about an hour to test this tonight; been really busy with work etc...

but..so far....
Not entirely sure what is happening yet; GPU Boost 3.0 could be to blame.

The tool is definitely doing "something" as my power reading shoots up (or down) on HWINFO64 as I *apply* voltages on the tool. -- even though the reported voltages in Precision/GPU-Z/HWinfo64 stay the same. :-)

Is there another way to get an accurate voltage reading? \/ reason below:

One quick test I did was a +150 clock offset in Precision (about 2152mhz +/- 23mhz) with a normal voltage of 1.093v ...ran fine...(but then when I applied the *same* voltage using the tool it crashed.

I should have a bit more time to play around more over the weekend so I'll have a proper look when I've got more time. Test above might have just been something else....

Anyway nice work Kingpin this is definitely a fantastic step in the right direction.

For the "upcoming" over-clocker; this is where the fun all begins. (Before having the confidence to eventually move onto more Extreme LN2 benching for example) :-)

Best regards, back soon.

You need a multimeter and connect the "Probe-It Cable", 1st pin is NVVDD and 2rd is GND.

Came home for lunch today (from work) and got 30 minutes.

Just repeated lasts nights experiment and applying the same voltage on the tool with what was already being displayed didn't crash driver this time. Very good news :-)

I think its time I invested in a multi-meter so will be going shopping for this as soon as I get an afternoon free (hopefully this Sunday).

Will be back then.

Quick question: Is this one of the pins on the evbot connection on graphics card (next to power connections)?

[johnd0e]

No the probe it/dmm connect is next to the evbot connector, its a thin connector with every pin in line. Touch the outer two pins with DMM probe to read your core voltage.

ahh yess I see it now; thanks... so left two pins :-)

I'll be shopping for multimeter tomorrow afternoon.

Any specifications I need to look out for/recommendations?

I want to also be able to do a few basic mods in the future too as my confidence grows.

Thanks,

Nick

quick and dirty picture showing each pin. every other pin is a ground, so from left to right: vcore(GPU) - grnd - mem(dimm) - grnd - io(PLL) - grnd - pch(3.3v) - grand - vsa(12v) - grnd



hope that helps.

[nrpeyton]

excellent thank you :-)

thanks.

Just got home with my new multimeter.

Tool seems to be working perfectly :-)

Thanks so much Kingpin you are a legend :-)

Quick run showing 2177mhz more stable at higher voltage:
2177mhz @ 1093mv -> 21782 http://www.3dmark.com/3dm/16027936
2177mhz @ 1150mv -> 22161 http://www.3dmark.com/3dm/16028633

My baseline will be low due to old AMD-FX CPU

Could this tool change the voltage of EVGA 1080 FTW?
