which evga 970 is that, what is that pn code
which brand of vram is that card, i have got ref 1.2 with eplida vram and 1853 vram clock is the most stable level that i can get in gaming without any problem:(
I think its the SSC one.. each card have there own limit..
the memory clock depend on the manufacture..
Hynix will max out at 7400mhz
Samsung will hit 8000mhz
first Elpida hit 7400mhz max while the latest Elpida hit 8000mhz without any problem
To add to that, I've recently found Skydiver in 3D mark will crash overclocks that make it through Firestrike and quite a bit of Uniengine. I usually run everything I can find at an overclock I intend to use 24/7, then loop Heaven or Valley to check temps are comfortable over time, if that helps smile.gif
I'm actually in here trying to work up the courage to flash my new 980ti and have a question.
I've hit a voltage wall at about 1500mhz, I can go up to 1.243 (GPUz) on the stock FTW BIOS which is + 87 mv.
Thing is I'm at + 91 boost at +30 MV and if I go any higher at all its unstable even with the volts slider maxed, cant complete a Firestrike run even with +87 on the volts. No PWR limiter in GPUz just VREL and VOP at that level. I'm thinking my card might hit a hard wall at 1500mhz and suddenly needs a whole lot more for very little gain. Is that what happens with GM200?
Temps are at around 60c with the fan at 100% benching 3d Mark so no problem yet.
Anyone have any thoughts or experience to share, would a custom BIOS allow me to get a few more MHZ or do these cards hit a very steep wall at some point? I'm only interested for running benches for giggles, I don't need to push that much for 24/7.
with custom bios you can go to 1.281v + higher TDP limit +custom fan curve + no need for any OC software.. also no throttle at 67c
Upload your bios if you're willing to flash custom bios..
Could you make my bios 1.28 V, 4000 on memory and something aboute 1550 on core clock if possible for my msi gtx970.
With 1.26 V my max settings are 1530 on core clock and 4100 on memory. GM204MSI970.zip
Give this a try
MSI970----Dark.zip 136k .zip file
Core clock 1557mhz & 4ghz memory & 1.28v
dear mr dark you set my gigabyte 980 g1 gaming to 1507 mhz , 3.7 Ghz and 1.250V , but recently i once had a BSOD with an error called DPC WATCHDOG VOILATION
that BSOD isn't related to your OC'd gpu at all.. its an old driver related.. make sure all driver's up to date..
Hi Mr. Dark
First off, you're awesome for doing this for people.
I have x2 EVGA GTX 980 ACX 2.0
Card 1 ASIC: 72
Card 2 ASIC: 74.2
I've got 2 EK waterblocks on the way for them, and they are going to be on a loop with my 5930K CPU with a 3x120 radiator and a 2x140 radiator.
I'm not looking for any particular numbers as far as clockspeeds/voltages go, I just want to use what I have to it's maximum potential. Once I get all the watercooling gear installed I will report back with some BIOS for you!
Thanks for that kind words
Once you get your Rig together upload the stock bios so i can help you there
