6950 TF III (New question)

post #1 of 25
Thread Starter 
Scroll to the bottom for the new question.
So I am about to RMA this 6950, but was wondering if anyone had any ideas before I do.

Symptom: The card will lockup when under a load, this happens at around 900MHz, which it should easily be able to handle.

Tried Cures:
CCC 10.1, 11.4, 11.5, 11.5b - didn't work

1.3Volts - didn't work

Re-flash BIOS - didn't work

Checked PCIe connectors - didn't work

Any more suggestions?

Did you turn the Power Tune setting to +10% (or 20%- whatev floats your boat) in the CCC?

Side note: How are you tuning your voltage on your card? Afterburner has it locked out even after checking the boxes in settings, etc, etc.

Power Tune's are up, but will test again.

Also, for me Afterburner was never locked out. Just select the "unlock voltage control". I also am using the Beta 3 2.2.0

Ok, I think I might of found the cause to my freezes, probably yours too jagz. Believe it or not, my card was sagging too low. I just put a BBQ skewer under it to hold it up and am testing now. Try that fix guys.

Yep, looks like that was the problem, testing at 950MHz @ 1.25VCore (on the safe side) now.

what the hell? How was it 'sagging' in the slot if its attached to the PCI-E bracket bolted to the case?

bump your 'AUX' voltage +10mv for speeds +950mhz core for stability issues..another +10mv for +1020mhz core is helpful too it seems.

I am stable at 950MHz with 1.25VCore in AB. I think I'm gonna stick with this, as it seems to work fine. Temps are around 80c max in Furmark. That is with a 120mm fan and a small house fan blowing on the cards. The problem is that on these TF IIIs the top card sucks in the bottom's exhaust.

Probably because most modern cases don't have rear supports for the cards. This means that while the FRONT is secured the back of the card will still sag down because of the weight. This is especially prevalent on longer cards like the TF III or Lightning also because of the non reference heatsink
