Zotac GTX 980Ti AMP! Edition Overclocking help.

Dronbana · Aug 26, 2015

Hey guys, i really like my card but the problem is that the moment i try to get past 1433mhz on core and 500mhz on memory at stock voltage, i see artefacts. No matter how much voltage i give my card, doesn't make any difference. The temps stay around the 70s so i don't think that's the issue. Sometimes, when i apply full voltage without trying to go over my stable OC, i get a boost of 25-40 mhz probably because of GPU boost.
My question is, if i put a water block on my card, say EKWB's block and put it in a custom loop, will i be able to achieve higher clocks or is this the maximum point for my gpu chip?

Any help is appreciated.
Cheers

That may or may not be maximum limit. There may be a bios flash you could do to get more voltage since it should have a dual bios, under your own risk but also try lowering down your memory a 100 and then increasing your clock again if you haven't already and see if it helps. Some of the artifiacting could come from memory being oc too high.

There are limits to everything.

If there were no limits, we would all have our GPU's running at 200 Zillion Bytes per second.

I think we are still a century or three away from that yet.

I actually tried clocking the memory to stock and oc'ing the core clock, no luck, doesn't even take 5mhz without crashing the driver. =(
Nowhere on the box, or the site does it say that it has a dual bios. Is there a way i can figure out by myself?
Thanks for the reply =)

Absolutely, just trying to figure out if a water cooled card or low temps trigger GPU boost, if yes, then to what extent. I paid Titan X's price to buy the 980ti in my country so i hope you understand me wanting to try and squeeze every ounce of performance out of my gpu. Water cooling is just something that fascinates me more than it should =P

Try maxing the fans to get it to run cooler and test your theory. To me it doesn't seem temps are the problem, so water cooling may do nothing but further empty your wallet.

MarkW · Aug 26, 2015

I think you are very close to killing it already... There are limits. Do not exceed them.

Dronbana · Aug 26, 2015

Thanks a lot guys, got it loud and clear, I won't smoke my card. Thanks for helping guys, Godbless. Don't know whom to pick as the solution, you've all been really helpful and on the point, wish i could pick multiple solutions =(

Actually now that I look, I think it only has one bios. Most of the aftermarket cards run a dual bios so you can change things like that without having to worry about messing up your bios if it doesn't take the flash for some reason. With one bios, I wouldn't mess with flashing it in case it doesn't take it and that's probably the only way you could get more voltage through it, to get higher.

Mine only has single bios cause everything was sold out when I bought and I wont flash mine even though I want too.

Can your hybrid go over your current clock or is it something you're comfortable at and don't wanna go higher?
Just asking caus im still not clear if watercooling yields substantial differences or not.

Reaper_7799 · Aug 27, 2015

I'm stuck at 1292 base clock and 1502 on boost but I don't know if it's my vrms overheating or if it is voltage related. In afterburner, without changing your bios so you can get a good boost of voltage, the amount you can increase in afterburner is a very small amount that doesn't really help at all.

The only thing I don't like about the hybrid is that it doesn't do anything about cooling vrm's at all, so it has just the stock fan to do that. If you get a waterblock from say ek or something, I'm 95% sure they cover the entire board and cool everything.

Dronbana · Aug 27, 2015

So potentially higher clocks with the liquid cooled loop?

Reaper_7799 · Aug 27, 2015

Yeah definitely but it will also be up to the rest of your board and gpu and what it can handle. Even if I or you went full water block now, we wouldn't be able to know if we could actually increase anything until it was all set up to make sure vrms stay cool too, flashed a custom bios on it so that you can get a good amount of extra power and then try.

I ended up spending close to $850 with backplate, shipping to get it here fast cuz I don't like to wait lol and everything and at the time I almost went with a full waterblock from the start because hybrids hard to find in stock and kinda wished I had, it probably wouldn't have been much more than what I ended up spending.

I'm still happy with the performance of this card though. It's still strong at stock speeds.

Reaper_7799 · Aug 27, 2015

The power phase is strong on your card...10 + 2 or 12+ 2 so it's strong in theory to handle extra voltage and overclock more but it's no guarantee.

Dronbana · Aug 27, 2015

Haha, yet again im convinced to be content with the performance im getting with my card and shut up about it. Also, water cooled loop sounds like too much of an effort =P
Wanted a hybrid too but availability.....

Reaper_7799 · Aug 27, 2015

lol yeah I know the feeling, it's hard to be content but it's not that much faster for say 50mhz bump once you start getting past that initial bump of a few hundred from say the vanilla reference card at 1000Mhz. I mostly run at like 1400-1425 maybe. Seems to run everything fine for me.

Dronbana · Aug 27, 2015

Im at similar stocks so yeah, life's good. Thanks for all the input mate, appreciate it. =)

MarkW · Aug 27, 2015

Ever since GPU's starting being able to boost their own speeds, overclocking has become less and less beneficial. The GPU's are smart enough now to actually use almost all of the available overhead.

Reaper_7799 · Aug 27, 2015

Dronbana :

No problem man, at least our problems are good problems : )

Dronbana · Sep 5, 2015

Any advice on AIO gpu coolers? My card has been hitting 75 degs off late =(
