Flash an Asus Bios then you got an Asus wink.gif ... there are very few GTX1080 with custom VRM Controler (EVGA Classified and GALAX HOF the only ones i know)

The Strix OC T4 Bios together with the 369.09 Mod driver given me the highest Graphics Score yet ... 12188 with 2126/5576.

BUT the missing limits are a problem under air cooling since it wont reduce GPU Clock rate when the GPU reaches 62 Degree Celcius it sometimes freezes then or i get lower scores.

so i think the Strix OC t4 Bios is good for aftermarket/H20 coolers

With the Seahawk EK i would try the Gaming X OC Modus Bios, the Strix OC Review Sample Bios or the Strix OC t4 Bios.

If I were you I'd plug both. It's not going to draw additional power if it doesn't need it, so why limit it by hardware?

ohh,ok ill just tick with afterburner and XOC then,thanks.

I found out the vga 1080 ftw hybrid was longer than I expected and it covers 4 sata contacts on my mobo, its not a big issue but if i want to unplug the sata cables its gonna give me hard time. I have the XL R2 case and there isnt much space there and with the length of the 1080 hybrid+power connector that is required I dont have the space for the gpu.
Secondly I chose the 1080 seahawk x due to black/ silver/white theme and it fits great with my black and white theme in my case,and the fact that it has 1x 8pin connector which means less cables.

but I just wanted to know if I added the pcie power connector thats on my mobo if I get more TDP % in afterburner,I have now 105% TDP max on the seahawk x, and it seems IF I ever chose to try and OC my GPU that I could push it further with 120% TDP than with 105% TDP.
I dont have plans on modding the BIOS.

Oh, I'm not sure about that. I think that depends on the BIOS, tbh. Fun fact: My "MSI Gaming" card had a limit of 121%. After flashing the "MSI Gaming X" BIOS which unlocked the voltage from 1.075V to 1.093V, my slider actually went down to 107%. So I think there's some weird connection between volts and your power limits, probably because if it's drawing more volts it's actually higher % of power anyway. Previously, my graphs would show around 70-80% power drawn, now they say 80-90%, for whatever that is worth. So if I would take a bet, I'd say the sliders are fixed from the card's firmware no matter the pins connected, and also also tied with the available voltage limit.

Your GPU/OC runs into PerfCap Vrel when the difference between the PL you set and the used PL gets high without adding VDDC.

many Bios i have tried set way too high default or max PL. (for instance AMP Extreme, Gigabyte Extreme), and setting it under 100% got me higher and more stable OC.

the default and max power limit is set by Bios in Watt and its different from bios to bios.

you may check the default and max Power Limit in Watt by executing this in a command line:

C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi.exe -q -d power

Damn. You're much better off than I am. Too bad yellow would look too weird in my build, lol.

EDITED the above because I had my power limit to 95% instead of 107%.

To anyone who have their 1080 on water:

Did watercooling made possible to achieve higher clocks that on air would crash/artifact or did it just reduced thermal throttle (not affecting max overclock)?
post #6037 of 11174
Water should in theory keep a high clock while drawing a lower voltage... which for Pascal is supposed to be more stable? I'm not familiar with the concept of less voltage = more stable. It always used to be the other way around for my experience tongue.gif A friend has a FE running at 2190-2207 like a champ under water, never exceeding 40C. Forgot to ask about his voltage though tongue.gif If anything, water would help prevent the stupid downclocking that happens solely based on temps.
post #6038 of 11174
Is there a Tool or bios for Classified i can push my Voltage?
With the t4 bios i can get 2400mhz But i think there is a bug i have lower results in benchmark...
post #6039 of 11174
I don't have water (yet) but GPU Boost would push clock down by 2 notches at least if u're at 70+C instead of 4X. There're always 2 downclcking points which are at ~50C and ~65C respectively.
Not sure if it's just the "thermal throttling" you referring to. I would personally consider this as "GPU Boost doing **** to me" tongue.gif

Not better overclock just more stable card at least here with max load temps 38C i just dont see how any lower than that can help and idle wont drop much more that stock cooler with fans off 30C with my water is at 27C
