Assuming you mean VRAM (and not system RAM) -- the only sure way to make this stick is flashing a BIOS, although there might be a tool to apply the oc on login like for CPU and RAM.

I started getting crashes in games at the settings above, so I scaled things down until I can run more tests. I may try running at the +89mV with various settings.

in other words it would be best not to set a voltage target ie

your power target is set 110%? if you're hitting that, then think about flashing a bios with higher.





I think the reason I was getting crashes, Is I forget to adjust the fan speed on the card, for cooling the VRAM, So I've fixed that and am going to run some more tests.



I already did the "slowly work up at stock" and ran into instability around the 1470s on Clock, before I even started adjusting RamClock, which is why I assume I need the +89 Overvolt. I have no plans on flashing a Bios, I can't afford to get crazy here.

My question is: How safe is the Overvolting? Should I keep moving that up, and try to get the GPU Clock higher? Or just leave it as is, and work on the mem. clock? I've watched a few vids. and read some guides, but still pretty new to OCing. Anything else I should know?


Max temps I'm seeing is 41C so I don't think that will be an issue.



Edit: So I raised the Mem. Clock +100, and ran Valley again, with the same settings as above (+130 core clock) and My max Boost Clock dropped to little over 1300Mhz.. Whats up with that? Do I need to raise the power more?


Edit2: I raised the Voltage to +43 and I got the Boost Clock back up to 1480Mhz with the +100Mhz Mem. Clock and it ran fine. How safe is this? Still not going over 43C

On my Hybrid it runs at 1500 with +100 on the mem and +25 voltage. Stock Bios. I game at 7680x1440 and it does not move from 1500. Also, I have a fan controller and have the AIO fan running off that. I also made a fan profile to have the blower fan on the card spin up to 35% when the gpu hits 45C. (I have a warm room). This way I keep the vrm's etc cool. I have not had a gpu related crash since I got the card 3 weeks ago. Love it. ASIC is 80.9.

Got rid of my 970's in SLI to have a smoother gaming experience.

Hello

I am looking for a EVGA 980 Ti HydroCopper BIOS - has somebody an original BIOS of this Card?
post #9085 of 16162
GPU-Z is saying my Performance is being capped by "Power, Voltage Reliability, and Operating Voltage" at +56 mV, sometimes one sometimes all three. Not exactly sure what that means.
post #9086 of 16162
Power means power limit I'm pretty sure, voltage reliability maybe that its fluctuating and operating voltage could mean the over all voltage is too low. I could be wrong on all three of these but that's what I would assume it is wink.gif

What's your base clock? My Hybrid is at 1260 base clock and it will be around ~1490-1510 sustained boost under load. Stock BIOS, +87mV, 110% power, +200 on memory (3700MHz). ASIC is 82.1. I was bummed when I couldn't go past 1260, but it seems like the Hybrids are boosting higher than other cards since there's no chance of hitting the temperature limit... less than 60C under load with the above configuration.

I can't decide if I should convert my ACX 2.0+ Ti to a Hybrid or go full on WC. Full on WC is just so expensive.

If you just have one card and don't already have a custom loop, go with a hybrid kit. If you already have a loop, the block should only cost a little over 120usd.

Can anyone confirm that a kraken g10 will fit/work with the gigabyte g1 gaming 980 ti?
