Normal or Defective?

post #1 of 14
Thread Starter 
I just got my HD 6970 the other day off a fellow OCN member here. I ran a stability test and began to overclock. While running Furmark to test for stability my clocks fluctuate like crazy! Is this normal or do I have a defective card? I added a picture of what I am talking about. The core clock goes crazy while under load.

super tiny... cannot read, let me switch montors... but if all it's doing is fluctuating it's probably fine

I highly doubt it's defective, probably just switching between 2D/3D profiles?

try using a older (or newer) driver to see if that helps. Also try the card on another psu? Those Thermaltake psu's are terrible.

850watt not enough? Dunno just seems to act very weird while testing for stability.

Well a normal 850w is overkill for that rig unless you had 2 6970's. Unfortunately that Thermaltake is a piece of junk.

Edit: I see you have 2 of em I would say try a new psu.

Why is it a piece of junk? Works great for me.

You need to enable +20 PowerTune

Your card can't get enough juice from the PCI-E on such high stress and underclocks, go to overdrive in CCC and put PowerTune to +20, should also increase gaming framerates by a noticable amount! PS. You need to enable it every time your change something from MSI Afterburner, although it seems like its on +20%, you can drag it to like +10 and press apply, and then put it to +20% on both cards! Hope this helps fellow HD 6970 owner!

The quality of the parts are horrible. That blackwidow is made by HEC who also makes the tr2 series which are also junk. Ripple suppression is nonexistent and it cannot deliver it's stated wattage.
