Vram temps

Just a quick question, i just recently installed the Hybrid cooler on my Titan X and dropped temps from 67-70@60% fan speed on load to 46 degrees full load overclocked 115 on the clock and 300 on the memory. I know i could go higher but im concerned about the vram temps. Does overclocking the gpu clock or memory cause the temps to raise? or just  the general heat from the card and the oc'ing. It does have a backplate and has a fan blowing on it. 

I have tried using GPU Z to check the temps but this card doesn't have the sensor, i have used a digital temp reader and it says 111degrees but not sure how accurate it is..any thoughts?

first off, that cooler looks like it only covers the gpu and is not a full cover water block.  however, you still have the fan (it's a hybrid) cooling the VRM and other components.  try increasing the fan speed if you need more cooling over the VRM's and other components.

as for overclocking your unit, you definitely want to increase the power target first and foremost.  this will allow you to achieve your maximum potential oc.  some cards allow only +10%, some up to +25% over base.  i would tune this to max.  i would also increase the temperature target to 90C (you aren't going to hit that so don't worry).

next, see how stable you can get the card w/o increasing the voltage and only increasing the clocks (offset values).  you can then decide if you want to increase the oc further by adding some voltage to achieve stability. 

use Unigine Heaven and/or Valley to test stability. 

my 980ti's are: +215 (core clock offset); +500 (memory clock offset); 110% power target; +17mV (gpu voltage) for 1.18V

these (titan X and 980ti) are essentially the same gpu.  in the 980ti's case just with fewer cuda cores.

all of the stuff (VRM and Memory) that needs to be cooled is on the same side of the pcb, where the drum fan also resides.  this fan is what cools all of the components besides the gpu (which is cooled by the AIO cooler).  the back plate is for looks and some protection to the circuitry on that side of the pcb. 

46C (as you reported) is very good for this cooler.  i see no cooling issues.  i also see that you have room to push the oc higher and gain more performance while still maintaining low temps.  it's up to you.  you have to judge for yourself how much power limit you need.  you can tell if you hit a wall and the card starts to throttle down.  it's all a balancing act.  

fyi. the VRM's are the square things aligned in a semi (squre?)circle around the gpu.

Wish gpuz was able to tell me my vram temps but they dont show on it. Ive read that the vram temps are what limit people on high they can push the oc because of how hot they get on this card. Everywhere else is cool just not sure about the chips

sorry bro, i was unaware that there were memory modules on both sides of the pcb. i still don't think you should have trouble overclocking this card's memory.  as long as your ambients and overall case cooling (perhaps a directed fan at the back plate) are fine.   

Yep I do have a fan blowing on the backplate..about 4-5 inches away 12v full speed. Im still using my 800d so its not the greatest for aircooling but i also have an 80mm 31 cfm fan intaking at the front that supplies that 140 mm im talking about..so i "think" i should be okay.
The backplate that im using did have thermal pads for each ram module as well.

It would destroy the look for me and just add to the noise levels, I'm looking into getting the Caselabs SMA8 or SM8 with the pedestal and going from there.

Yeah i will never buy the 900d...i went down that road already and the quality was so awful. Id rather spend the money on something higher quality and allow me to change anything i want whenever. I couldn't believe how flimsy it was, the door never lined up correctly, hinge was defective and the plastic pieces that hold the front plate were broken on arrival. Heard nothing but amazing reviews on caselabs cases so ill be going that route.

 BTW I just realized that the handheld ir temp gun i have was set to f and not c so after checking the backplate during gaming it was at 45c.  so with heat dispersion along the plate i can expect the vram to be little higher but still safe..think im okay now. My temps never hit 50 during anything so i set my fan speed to hit just below audible(65%) around 48-49 degrees to help with internal cooling.

Well the 800d im using has been fine, all lines up no issues for the years ive had it. when i tried the 900d i was very unhappy. i see a lot of people with same complaints so i figured meh im not gonna try again.

Lastnight i switched a fan that angles down towards the card. Put in my noiseblocker 140mm pk3 and right now its idling at 22c.

Was on GTA 5 this morning at had no issues with temps so im pretty happy, only spent 60 on the pump and 30 on the led shroud from ebay..nice little upgrade to allow me to match and pass the wife's 1070 sc acx she just got LOL
