[Official] NVIDIA GTX 780 Ti Owner's Club - Page 685

post #6841 of 16498
Hi, first post here at Overclock.net honored to be here and be the owner of two EVGA 780 Ti SC ACX cards.

My question is i have 2 XSPC Waterblocks on the way http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_971_240_587&products_id=39810

I'm curious is the VRM temp difference that big of a deal compared to the EK Waterblocks which i've heard are very close to the XSPC block as for GPU Temps go, but roughly 8-10C cooler on VRMS.

So my question is, will i be hindered in any way, is the 8-10c going to really affect my overclocking potential.

I'm not looking for insane overclocks, but i'd like a fairly healthy overclock without going too crazy on the voltage, as i haven't really delved to deep into overclocking my cards as of yet i've already flashed the cards to the VBIOS provided in this thread.

So in short TLDR

XSPC GPU Block vs EK GPU Block, is the XSPC blocks i currently have coming in soon going to hold me back at all or run the chance of overheating my VRMs.

Side note, has anyone here used the XSPC block and XSPC Backplate, and weather ot not to remove the backplate under the ACX cooler.

Sorry for the long post but i guess i should come in with my first post being a big bang tongue.gif

I would also like to add that i am not new to Overclocking, so i'm not completely noobish tongue.gif

Shouldn't have any real impact on potential since you'll never see above 1.212v on a reference Ti. Might, just might, have some impact on card longevity compared to EK blocks, but it's still so much cooler than air. We're talking years of use before the difference shows here...most of us on OCN rarely manage to keep a card for a few months, let alone years. smile.gif

its pretty hard to get ahold of the 780 ti classified or kingpin cards, as why i went with the EVGA SC ACX.

Going back to 4 days ago, not sure if I'm really believing 100C VRM temps on all of these cards @ 1.2v

That would personally mean a 90% increase in VRM temp as compared to GPUz and Aida64 reported VRM temps.

I'm not here to claim software sensor readings are ultra accurate, and I don't own a thermal gun, but what is being suggested sounds grossly exaggerated in my case.

FWIW, my VRM temps as reported by Aida64 read as 55C when pushing 1.2V. Fans at 80% on my Ti Classy. Core is at 60C. From that, I'd realistically estimate VRM temps are probably between 60 and 70C

i can't seem to find my vrm temps, in sensors on gpu-z 0.7.6, i have aida64, just dont know where to look.

Gpu vrm temps appear almost right down the bottom on the sensor list, just above the voltages section.

I have the second most recent full release of aida64
post #6847 of 16498
i dont see any VRM related tempatures in the sensor list.

Not sure if things change depending on Ti models. I didn't think they would, but it's possible I guess

You sure about that. Got the same card. The OC GURU II seems to be pretty much the same thing as Precision X, works the same. I could even get 1.212v with it and precision x with the stock bios, but i guess that's normal.

On OC GURU II, I can set overvoltage to a max of 1.263v, but on nvidia inspector it still doesn't go higher than 1.212v.
