Asus GTX 670 DCU-2 TOP Throttling for no reason. RMA?

post #1 of 15
Thread Starter 
Hey Guys

so i've recently noticed a problem with my GTX 670 Direct CU II Top. I've owned the card for about 3 months now, and had it running fine overclocked to +40 offset on the core clock and +300 on the memory clock. After GPU Boost and Kepler Boost the core clock read at about 1307 during heaven benchmark runs.

Recently while playing guild wars 2, the card seized up and cut the signal to both of my monitors. After a few powerdowns i managed to get a signal and get back onto windows. Out of habit during crashes i opened up bluescreen viewer and apperently i got a 0x0116 Error which i believe relates to a VRAM error. anyways after that i uninstalled the video card drivers and did a driver sweep with driver fusion to be safe than reinstalled them again. So thinking i was in the clear, i left everything at stock and started up heaven benchmark to see if it'd crash again... it didnt crash but what shocked me was that the clock speed was actually lower than the GPU boost clock which at stock is rated at 1137 but was running 1110. I ran the test a 2nd time and this time with GPU-z on the 2nd window to monitor what was going on, apperently the voltage was fluxuating along with the coreclock too, so my guess is it is throttling but that doesnt make sense since the GPU temp was at 50c and the power usage was only at 78%.

I'm beginning to think that i may have blown something on the card when that crash during guild wars occured. Should i try for RMA or does anyone have any advice? Also if i choose to go try for an RMA is Asus reliable?

Things i've tried:
-revert to stock clocks
-reinstall drivers
-try different PSU
-Update VBIOS

I guess at stock if the card fluctuates in clocks that is normal. It is based on the temps and TDP. If the clocks on the card are running too high for the TDP it will lower itself 13 MHz, also if the temps are around 69 * - 70 *C the card will lower itself 13 MHz again.
My GTX 670 fluctuates between 1228 MHz to 1110 MHz depending on the temps and load.

i find that weird since my temps never broke into 60's and the power usage stayed in the 70% area topping at 78 on my last heaven bench.

If the card give you your targeted framerate eg; lets say 60 fps. the card will downclock itself too to save power.

i suppose, though on precision X the frame rate target is set to max which i assume is uncapped. still it also leaves the question why i was able to hold a stable 1307mhz through heaven bench without any fluxuation until the recent signal loss problem.

Did you happen to update the video bios before you noticed this discrepancy? By discrepancy I mean where your core clock is capping out at a lower 'observed max clock' (1110MHz) than your Stock 'Boost Clock' (1137MHz).

Are you familiar with the term "Kepler Boost Value" (see the first link in my sig for more info), and if so, did you ever calculate what it's value was for your card before you had these issues?

Oh ... and does it only do this on Heaven? And does the Afterburner/PrecX graphs of Voltage levels show the same fluctuation as GPU-Z does?

I updated the vBIOS after the incident hoping it would remedy the issue

I am familiar with Kepler boost and calculated it at the time to 130mhz

I tested it in Furmark and it also had the same result as heaven, and also in GPU-Z's Render test with the render test having the same issue of fluctuation but actually reaching the desired speeds more consistently.

This is normal behaviour for the kepler. Throttling happens sometimes, especially new games without an updated driver. You can try setting power management in your CP to "maximize performance" instead of "adaptive" and that may help - basically what happens is, when you enable vsync the kepler thinks it doesn't need the horsepower and will throttle - changing your power management can help with that.

Try some other games and benchmarks like heaven and 3dmark11. If the boost sticks (while under 70C) you are fine. Again, this *will* happen with any kepler GPU in some games and it is unfortunate, although i'm not sure if GW2 is fine tuned yet with 306.02 drivers - try some other programs and monitor your boost - I suggest games like bf3 or crysis 2. The newest beta driver can help with GW2.

sorry i shoul have mentioned that i changed a few settings in the nv control panel, i did enable maximum performance under power options globally and disabled vsync globally as well (i only use vsync when i notice screen tearing in games).

The programs ive tested and noticed the fluctuation was in heaven bench, furmark, and gpu-z render test. Ive also played bf3 on it and noticed the same problem but the clock actually dipped further down at some points to about the mid 900mhz area.

Sounds like something is awry, that definitely isn't right. I think asus released an updated BIOS for that card a couple of months ago, that might be worth a shot.
