GTX 980 Ti low core clocks, low temps

I believe its kelper boost. Is it any different to setting 'Prefer maximum performance' in Nvidia settings > Manage 3D settings > Power management mode?

kboost seemed knackered when i tried using it. It make my desktop black around the edges and did not change clock / voltage at all on the card

'Prefer Maximum Performance' basically makes it run at stock clock full 24/7 (so like 1100-1200 what ever you have, not down clocking to 300 when on desktop idle for example). K-Boost forces it to run at full boost clock (your 1400-1500), not really something you want to have on 24/7 but if you run a benchmarking test it gives you confidence the card is not holding back at any point.

Not sure why it killed your desktop though... The tick box is on the top right of Precision I think.

It didnt kill the desktop, it just made the outside edges all black. Is kboost available in afterburner? I find precision is horrible to use compared to afterburner. Just things like the fan cuve option making precision flash /blink and the option not opening up
The whole layout just seems messy compared to afterburner
 
You really should talk to Lathian on that thread I linked you. He knows what he is doing and I'm confident he can help you get better performance from your card and remove throttling and perfcaps.

Probably needs more power and voltage to go higher. You are running it pretty high as it is but likely needs a custom Bios to get more out of it and remove Perfcaps etc.

There's a great thread here with custom Bios for the Gigabyte series. Not directly suitable for your card but you could download and copy the settings and make a new Bios then flash it. Or get someone to help.

Of course all done at your own risk!

Edit - If you look on the second to last page, the thread and Bios creator has already made a Bios for the Classy. Check with him that it's suitable before use though.

I have searched through the last few pages of this and cannot find a classified bios. Am I just being blind?
 
Thread moves fast!

It's on page 370 post 3699. Tell Laithan your issues and ask if it's fine to use first though. It appears that one may be for water cooled cards where he increases the voltage a bit higher. He might have an air cooled one too. If not I'm sure he will knock you one up if you ask nicely. It's only a case of copying the settings over from his existing custom Bios. You can even do it yourself using Maxwell Bios tweaker. The thread is mainly about the Gigabyte cards but most the stuff is the same.

Flash, max the voltage and power sliders in afterburner then start overclocking!

Save your current Bios first then you can always flash back if need be.

I have noticed that when using afterburner the Power Limit and Core Voltage sliders are not taken into account. e.g. I set power target 110% and it will never go over 100% whereas if I used Precision X it will. The same with Core voltage, nothing over 1.2v but using Precision it will hit higher with overvolt

I suppose it's brand limited then? There seems to be some recognition going on. You could overvolt without modding the BIOS then?

Just tried overvolt without flashing the bios and the driver crashes a few seconds in to Heaven 4 when clocked to 1505Mhz. I guess the increased voltage has no effect - even though the card is only around 65c when it crashes :confused:

I thought more volts = increased reliability but more heat? Not more volts = more instability. I'm still tempted to flash as its dual bios and I am trying to reduce the clock decrease at such low temps (so I dont need 80% fan at 65c!)


I have asked EVGA the following
If i was to use the standard fan settings the fans would start at 60c then the card would downclock quickly as it reached 66c.
Is there a way to change this downclock temperature (and down voltage from 1.2v) using Maxwell II bios tweaker?

I read your posts on Overclock. With Laithan's response it seems the voltage on the EVGA cards is locked for some reason so you can't really use those custom bios settings to maximum effect. Everyone with Gigabyte cards seems to be getting great results. Load's of people had throttling problems etc like you and the custom bios cured it.

I had a quick scout around and it seems there's lot's of people bios modding their EVGA cards. I even came across a thread where KingPin himself had posted custom ones. You tried them?

I haven't looked into it too much but I'm sure there's a solution with some tinkering!
 
Yes, try custom BIOS. It might be worth dialling your memory clock back a bit first if your pushing the core. There must hardly be any benefit at all taking it past 7800-8000/+400-500?
