[Official] Nvidia GTX 980 Ti Owners Club - Page 921

post #9201 of 16103
Any tips on getting more speed out of the memory (custom BIOS, etc)? I feel like I've hit a wall - I can't go higher than +200 on the memory without getting crashes. I've seen lots of people with +500 or more, when I try that I get lockups within a few minutes. Power target is set to max. Am I just unlucky?

I have a EVGA 980 Ti Hybrid.

Start with memory only and see if 200 is the wall. Usually i only see artifacts with too high memory not crashes.

You might be unlucky, but then again you DO know that you gain much more from higher GPU clocks than memory, right? wink.gif

Im sure it's identical with it using the same setup.

8pin = rated upto 150w(150000)

Total tdp is where the 75w from the Pcie lane is added. Naturally you're already set to hit 324w, but Nvidia limits these cards to 250w. Manufacturer's allow 275w +(110% for you in your overclock utility) If you raised your max tdp to 324 in bios you would allow max potential based off base data. 201w on a 75w rated connector and 257w on a 150w rated connector might not be healthy.

don't let those SIG specs throw you off too much. the standard terminal (mainstream PSUs) can supply 8 amps while better ones can supply ~11-13 amps using 18 gauge wire (better PSUs use 16 gauge).

i am talking these:


each wire can supply 96 watts min for 192 watts-6 pin, 288 watts-8 pin. so if one is using say a corsair CX series, yeah they're pushing the 6 pin but a better PSU like that seasonic-X they have could handle much more (264/396 as opposed to 192/288)

You probably already know this, but make sure you have an aggressive fan profile setup on the Hybrid, to keep the Vram cool. Its set on Auto by default, which can result in crashes because the fan won't be running fast enough to cool the ram, because it bases its speed on the temp of the GPU core, when set to auto. I had that happen to me, the fan on the card would be running at 1900rpm with the gpu at 42C, and I'd get crashes.




How safe is modding the BIOS anyway? I've never had reason to consider it before.

Oh that's interesting, what have you set your profile to?

What are you guys using to OC your 980Ti? I've used AB but switched it out with EVGA PrecisionX 16 because it had a feature to OC my monitor. And what are your stable OC settings? I just don't want any conflicts of software. BTW I love this card. It's super fast at stock settings but I want to push it as far as I can. I'll rep you if someone can show me your settings. Thanks.
