A few Maxwell Titan X questions

Hi, I've just got myself a Maxwell Titan X as an RMA replacement for my 295x2 and as I've not had an NVidia gpu for ages now I've got a couple of questions that I'm hoping people on here could help me out with.

First up is what sort of temperatures are expected from these cards? When I put it in with everything at stock I could see (using MSI Afterburner) it was idling at about 60 degrees which seems pretty high and as soon as I did anything 3D it ramped up very quickly to 83 and started to throttle. I did note however that the core and memory clocks seemed to stay at full settings all the time, even when idling and only downclocked when the monitors went into standby, is that normal behaviour?

The fan speed by default seemed to be very low (~35%) so I suspect it just needs a slightly more aggressive custom fan curve?

With regards to overclocking I see in MSI afterburner that I can up voltage, core, mem, power limit as usual but also have a temperature target now as well but even with the fan set to auto it doesn't seem to use fan speed to help meet the temp limit? It just throttles the core speed as soon as it hits the temp limit rather than upping the fan so I presume the fan control is independent of the limits?

Finally, what sort of overclocking can I expect from one of these cards and is it only really possible with significant extra noise from the fan to stop throttling?

Thanks for any help,

Ross
 
If it has a blower cooler then those temps are to be expected. Most people buying a Titan I would have thought also have the money to put them under water so dont worry about temps.
Could try removing cooler and better TIM applied.

Only way for better overclocking is better cooling.
 
Yeah it's the standard blower cooler on there, I'll have a play with fan curves and see what's the best balance between temps and noise then.
 
In the nVidia control panel under Manage 3D Settings set the power management to adaptive (or optimal but I find the optimal setting a little buggy personally).

It shouldn't really be idling that high at full 3D clocks - 30-40C would be more normal unless you have something on the desktop that is keeping the GPU slightly busy. 35% fan speed is normal for a true idle situation but won't be enough if the GPU is actually doing stuff other than normal light desktop utilisation.
 
The clocks should downclock at low loads. I imagine your high temps at idle are due to it maintaining 3D clocks as mentioned by Rroff. I would try checking power settings (though by default is usually optimal), if not would use something like Driver Display Uninstaller and make sure all the drivers are removed and try a fresh install.

Your temps under load are normal, by default the card will target 83 degrees then drop off the clock speed to stay around that limit which is what you observed. To maintain the higher clock speeds you will need to independently set up a fan curve. My cards did 1450 Mhz-1500 Mhz for benching on stock cooler with fan ramped up to max. Under normal use with fan pretty high but not deafening, they landed in the 1350 Mhz region.
 
Thanks for the info guys. Monitor wise I have 2 connected, one a 1440p 144Hz via DP and and old 1680x1050 60Hz via DVI. Is there still any issue of the cards staying at higher clocks with certain combinations of monitors or is that all fixed now?
 
Wasn't there some bug when running a 144hz monitor which caused nvidia cards to run at full clocks when idle?
If I recall setting the monitor to 120hz cured it, atlthough, the newer drivers don't seem to suffer from this problem.

Could be totaly wrong but I do remember reading it some time ago.
 
Yeah I vaguely remember something like that but I haven't really been paying much attention to Nvidia stuff for a couple of years so I can't remember the details.
 
Depending on your setup having more than one monitor connected can cause the GPU to be running a higher level of utilisation even if it is clocking down somewhat it will still hold in low power 3D state instead of lower power 2D state or whatever is appropriate for your GPU there might be no way to avoid that.
 
If you have more than two monitors attached, the card will not idle. You should also check that the fan is actually working: on my first card the fan failed within a day.
 
That's a good replacement imo taking into consideration multi gpu support these days. Set a 1:1 fan profile so fan speed mirrors the temp. And get that titan clocked to 1400-1500 on the core and +400-500 On the memory Maxwell was the best in terms of gains from overclocking imo the only difference was my old gtx 460 got it to 975mhz vs 675 stock and it was around 40% faster!
 
Thanks everyone, I've sorted out the fan curves and got the temps under control now. I'm mainly using it for mining at the moment so not really pushed the Overclock yet but put about +100 core and +350 members so far. If I ever actually get any time for gaming I'll get a new profile setup for it and see how far I can push it.
