EVGA GTX 670, bad card or faulty boost?

post #1 of 15
Thread Starter 
So I spent a few hours playing at with no issues since I got this yesterday but today, I've been getting artifacts, drivers crashing, black/white screening, just about everything, I decided to monitor precision-x and see what clocks it's actually running at, apparently the core clock is running at upto 1124 on load even though the card is stated as having 980mhz boost, 915mhz stock, with the memory running at 3000mhz.

I can't figure out if the card is just a bad card and needs an RMA or that for some reason it's running 150mhz above it's factory clocks even though I have it set to stock, and I should just lower it by 50-100mhz, I just find it very strange but maybe this is how boost works and my card is a dud, or my card thinks it's better than it actually is and is ramping up way past it's threshold.

I'm running the latest, stable drivers (301.42) although I've tried three with the same issue, I've reseated the card, tried another PCIE slot, tried running it at PCIE 2.0 instead of 3.0, unsure on what to do other than to just lower it as said, it's my first time ever using a nVidia card, I've only used AMD for 8 years now and it's not a great start mad.gif. I've attached a picture showing that precision-x is marking 980mhz as my "boost" clock yet after playing Skyrim for 10 minutes before my drivers crashed, it got upto 1124, is it possible that I could just increase my voltage to fix this?

Thankyou in advance for any suggestions.

I don't know if this is normal either, but I launched Skyrim and the power % in afteburner shot upto 371% for a second and then the drivers crashed:

It stopped crashing now I lowered clocks by 500 core and 500 memory, not sure what to do at this point though, I think playing with voltages might help me but I've no idea where to start.

well the fact that its boosting to 1124 is not a bad thing. thats just the card boosting to its max boost value. increase the power target to max and see what max value the gpu clock gets to. that can also help stabilize the card because perhaps its reaching that 1124 boost clock but the power % is not high enough to maintain it.

the card is rated at those settings you mention but it doesnt take into account the kepler boost you will see. when necessary, the card will boost above the stock values given the power % is enough to support it.

for example my card in gpu z in rated at gpu clock - 967 boost - 1046. If my power % is raised to the max value, my clocks will raise above 1046 to 1150 because of my cards kepler boost when under necessary load.

when you overclock the gpu offset in precision x, it will overclock the gpu clock from the kepler boost value. so if your kepler boost happens to take your card to 1124, then upping that gpu clock to +10 will change your max boost to 1134. you will not notice these clocks unless your power % is high enough however for some users 100% is high enough for the max kepler boost value take effect.

Thanks for the reply AV98911, I lowered the core and memory clock by 500 and increased power targe tto 122% (maximum in precision-x) and the drivers are still crashing, do you think changing voltages might help? It's currently at 988mV.
post #6 of 15
does the voltage stay at 988mv even when u launch a game or 3d app? if so try restarting your computer. perhaps something is causing it to stay locked at 2d clocks/state.
the card should boost the voltage up to a max of 1.175 on its own. i guess since you still experiencing crashes its because the first crash is caused the voltage to be locked in a 2d state at 988mv. My card runs at that voltage while idle. In games it boosts up to 1.175.

after you restart keep the values at +0 for the gpu and mem clock. im sure its something simple like the card trying to boost too high while the card was locked in a 2d state.

Changing voltage in precision/afterburner does not work. (unless you own a msi lightning/PE)
That is the idle voltage you are seeing, it will go up to 1.16/1.75 while stressed.

It looks like voltages are ramping up, a minute or so in Skyrim while monitoring get's me something like this, it also says at the top (1500, 100, 100, 2,0) which surely can't be right:o.

Mind you post your full system spec? (Power Supplies, Motherboard. etc.)

 

There is a new driver (beta) 304.79. 

 

 

Before messing around, uninstall Precision X and other software that allows to control the card and reinstall the driver or update it. Did you try to run games without any Prec X and other software? Are you still getting artifacts at stock settings?
