Asus GTX 770 locked at idle clocks with insanely high TDP(430%). Can it be fixed?
I got my hands on a fairly good(and a bit old) gaming PC recently. Everything seems to work fine, except for one thing - the Asus GTX 770(a Direct CU II model, 2GB DDR5) that is inside it. The card is surely not dead yet, as it boots up normally and there is zero artifacts/screen glitches. The problem with it is that it is locked at idle clock speeds, which I believe is caused by the 430% TDP shown by GPU-Z and EVGA Precission. The core clock is at 135 MHz and the memory clock is at 162 MHz and they won't change under any load. I guess it is the card's "defense mechanism".
I have tried a few simple things, as at first I thought it was a bad clock/driver issue:
- I sweeped all the drivers and installed the latest 391.35
- I reseated the GPU
- I reset the CMOS
- I played around with the power management settings both in Windows and in NVIDIA's settings
Sadly, none of those worked(as I expected). The drivers doesn't seem to be a problem. It also seems that this is not caused by a bad overclock, as both the clock speed and the voltage are at stock.
I have read a few threads here and there about this issue and I saw somebody mentioning a fix with power management tweaking with Kepler BIOS Tweaker. This, however, is the breaking point for me as I will likely kill the GPU completely, as I have no idea on what and how to edit the VBIOS.
So, to sum up, it seems it is more like some faulty hardware part(maybe a power controller?). My questions here are as follows:
Have you guys had similar issues?
Is there any way to reduce the insane 430% TDP, so the clocks are not locked?
Do you guys have any idea what harware fault may cause this and can it be fixed/changed?
Is there any way to "somewhat" fix this by tweaking the VBIOS?
I am looking forward to any answers, so keep them coming! I really hope there is some fix or workaround to this! Also, thanks for you time!
P.S. I can't post any pictures of GPU-Z as I am a free/new user.
P.S.S. I now added the pictures from GPU-Z.
