Sapphire 7970 crashes with 1.3v? - Page 6

post #51 of 96
Hello guys! This is my first post on this forum.

I bought a Sapphire 7970 on monday and since then ive had a few issues with setting the voltage.

Ive used both trixx, MSI AB and Overdrive, but taking the card beyond the stock voltage causes it to power itself down even with powertune at 20%.

I also seem to experience quite heavy voltage drops (VDroop?) according to MSI AB. Im quite new at GPU OC, but im familiar with CPU OC and this makes no sense to me.
Even running at stock, the voltage will hang around 1.030 according to AB, and increasing it by anything will force the card to throttle (or so i think. Black screen of death basically..)

Anyone able to help me out? Im all new to this stuff, but i cant seem to find anyone with similar issues.

Since im too dumb to find out how i change my system in the signature, the rest of my hardware is basically i7 2600k @ 5GHz 1.4v, ASUS P8Z68-V Pro, 4 sticks of ram (8GB) and a Corsair AX 850 PSU.

Any help would be appreciated smile.gif

I'm also having problems, unless my GPU is just a dog, I can't go over 1170 core without artifacts even at max GPU volts. If I follow Ken's advice and disable CCC after setting Powertune, the max my clocks will go to when setting in Afterburner is 500MHZ.

These cards are just few days old. Not sure how everything works. Try to set the PCS +20% then disable Overdrive only then go to task manager to stop the services of CCC.exe or MOM.exe see how it goes. Play around with this see which one works.

 

Make sure the power supply can sustain low ripple on the +12V and has enough wattage. Also, make sure to plug in the power for the motherboard from PSU for additional power to PCIe slots.

I've tried everything everyone has said and its still a no go. The only thing left to try are the following:
  • A fresh install of windows. Going to wait to do this one though as I have a new SSD coming next week.
  • Registry editing. I haven't done much of this so I would like to wait and see what people with more experience than me come up with.
  • BIOS editing. Same as above really. My intention was to do this at some point anyway but at the moment I'd like to wait for the more experienced to pitch in (not neccessarily in this thread but in general).

If anyone gets any more news or finds a solution please keep us updated.

How does a motherboard operate without the power plugged in? All possible cable are plugged in. Main motherboard supply (24 pin?) and CPU power (8 pin)? Could you elaborate on what you meant please.

From my own webserver http://bit.ly/xjby4g
Download, unzip, run file

I may have found a solution, thanks to DB's suggestion! Ok, so I decided to uninstall Trixx, since as mentioned before it was not working well with CCC. When both were open, I wasn't able to apply any settings in CCC, and Powertune would revert to default any time I hit "apply." What I did was download DB's file that unlocks the clock limits in CCC, then I re-installed Trixx. I closed CCC, opened Trixx, and applied my OC and voltage settings. While Trixx was still open, I opened CCC, and to my excitement, I was able to adjust OC settings and Powertune while also applying them. Obviously, make sure that when you are adjusting the OC settings in both programs, that you keep them both at the same numbers.

So far I have constantly opened and reopened CCC and Trixx together, and I have yet to have any issues with CCC applying OC settings or Powertune. I know in the HARDOCP review, the reviewer was able to adjust clocks in Trixx, and the OC settings in CCC automatically unlocked to higher limits, but for most of us that has not been the case. The method I used seems to be best for those in a similar position as me. Keep in mind, I haven't actually ran any benchmarks with voltages near the 1.3 range, but feel free to try it out yourselves until I can report back with my own observations.

I've also noticed that when I adjust the clocks in Trixx, they also auto-adjust in CCC appropriately, which is a very good sign!

I haven't mentioned it anywhere but that BIOS mod was one of the first things I tried. Hopefully it has done the job for you so get that voltage cranked up and see what she can do!

As for me I caved in. Ive just started doing a fresh install of windows. I'll report back soon.

So I went through my benchmarks and tried to bump up voltage near the 1.30 range, still got too many artifacts. It really just seems as though the card just doesn't like voltages anywhere from 1.24-1.30. Its kind of disappointing, since there will now be no need to consider liquid cooling to really push this card to the max. I'm beginning to wonder if AMD's strive to make this card smaller and more energy efficient has compromised its ability to take on more power. I understand all chips aren't going to be able to OC the same, but my card is pretty darn sensitive when it comes to voltage. You can barely go above stock voltage without it acting strange in benchmarks and causing artifacts.

Well EK just hit 1350 mhz core / 1750 mem with full cover water block.

But how sensitive are they really? When I'm running Heaven Benchmark, my temps stay in the low 70s. And that's with me testing 1200/1600 at 1.2-1.225v. If the card can't even perform properly when in the 70 degree range, I'd say AMD did a disservice to their customers.
