[Computerbase] Early GTX980Ti Roundup

[RussianSensation]

I found this questionable leak on the lightning: http://www.game-debate.com/gpu/inde...ion-vs-geforce-gtx-970-msi-gaming-4gb-edition
I really want to replace my 680 GTX Lightning with this one.

I am not sure how credible that site is. I don't see any source for their data. A lot of after-market 980Ti cards listed in this thread already hit 1500mhz boost in overclocked states. The 1342mhz boost for the MSI Lightning or 1800mhz memory aren't sufficient to tell us if it's worth paying the premium over the other cards listed in the thread. I wouldn't be surprised if the Classified can already hit 1550mhz.

This is something interesting too:

""Honestly speaking, I think most end users don't even realize how maxwell gpus are voltage capped at ambient type cooling. I can tell by many of the comments at OC.net, elsewhere, and also here in these card XOC bios threads. Especially compared to kepler. KP 780ti scaled great on voltage with air/water temps. Basically, more voltage = more clocks no matter what temperature.

With 980 and later gpus including titanX, the scaling on air/water has all but almost gone. I would say about 95% of all maxwell 980,titan-X, and 980ti gpus NO MATTER what vga brand pcb it is on, DO NOT SCALE with more voltage than 1.25v-1.275v at temps warmer than 25c or so. There is no magical bios that can effectively remove this.

This is exactly why almost every moderate-good asic titanX, 980, and yes 980ti clock around 1550mhz MAX AVERAGE at say 45-60C loading temps.
If you put 0c and colder on the card, you will see MUCH different behavior than what you see on air (green garbage all over screen when raising volts over 1.23-1.25vv or so)

Cards with very good ASIC value (75% and up) will tend to have the most "overclocking", but just like about every other maxwell gpu, they cannot overvolt past 1.23v-1.25v.

So highest asic cards like 80% +are almost always going to be the ones that can 1600+ on air/water, and again they do it pretty much WITHOUT overvolting over 1.23v-1.25v. Maxwell gpus with lower asic value like 65% will not be so great at air/water because these low asic gpus need voltage to scale compared to match the overclock of the high asic gpus( USING SAME USABLE VOLTAGE 1.23-1.25v)

The bios's I posted basically allow you to set a higher voltage on air/water. Some gpus can scale more, some cant, some actually will NEED more voltage than was previously needed to run same frequency. All different.

Have a better understanding now?""

For potential buyers of a 980Ti card (or a future NV card), I made a separate post about Zotac's Extended warranty in another thread. Essentially, Zotac extends the warranty for free to 5 years worldwide and to lifetime in North America if one registers the card within 28 days of purchase:

This is a big win imo.

Thanks RS, for pointing this out as I was truly unaware that Zotac had such a warranty.

Interesting theory. I want to test it now. I have seen 1492MHz max boost on my 980 Ti on water but I just stopped going. No wall or instability.

I'm curious to see just how high I can push it even though I have no need at the moment.

Ordered and payed for a 980TI G1 from Gigabyte for the low price of 874.42 US Dollar in Norway yesterday. Ahh how i love the strong dollar, thanks guys. /sarkasm

I have a EVGA 980ti SC+ ACX2+ with an asic score of 83. I was hitting max boost of 1440mhz out of the box and I was able to get into the 1520s by overclocking with no additional voltage. I have been using this setting for about a week and I consistently see 1500s in GPUZ while gaming.

There definitely seems to be a wall at around 1540mhz. I get bad instability above that regardless of voltage/power target. Temps never get above like 60 when I use the aggressive fan profile.

Just received the EVGA GTX980TI SC+ACX2+ BP tonight and installed it in my 3770k rig replacing a Sapphire R9 290 TRI-X OC. WOW is it a great card.

Ran 3D Firestrike with both the R9 290 and the GTX980TI

Overall score R9290 reg 9528; GTX980TI reg 14949

Really dislike this new layout. Hate having to click through each section to get all the VGA info that was in one section before. Some cool info here didn't know that stuff about the nvidia voltage.

So basically, Fury being locked at the voltage it was at hurt it far more than it hurt Nvidia, especially when going up against cards with higher asic scores (and therefore higher OC clocks).

I checked my ASIC the other day and it's 76.5%. If GPU-Z's info about that is right, it might play into my headroom a bit since I'm on water. Still haven't gone back to push it yet. Working on a paper and don't have time to tweak.

What's your T. Amb? I get 78c stock vsync off...
Open bench?

I was benching again last night and temps got up to around 70C for the GPU with batman, GPU clock was 1512-1524. I used the aggressive fan profile to keep the temps down because (slight) throttling seems to start around 70C. When I did my early benchmarks the computer was on top of my desk with nothing around it. Now it's under the desk and part of the exhaust vent is only a few inches from my couch.. Probably need to improve my airflow sitch.

It's weird though that my card has a higher asic than most I've seen on the internet and maintains boost over 1500, but my fire strike graphics score tops out at 20800 while other people's cards break 21000. It's a 1% difference, but STILL.

As a follow up, I hit 1545MHz max boost clock (sustained constantly, as it maxes out at 38C on my water setup). Memory is around 7.8GHz.

Not too shabby, but after stress testing with several Heaven loops, I just put it back to stock. No need in wasting power if I don't need it right now. I saved the profile, though. :whiste:
