Background:

 

I Bought a 1440p monitor and picked up a second graphics card on Ebay to crossfire my XFX 7970 with

 

Problems:

 

-VT shows Only 20% usage in fur mark then crashes (the VT by itself and in crossfire)

-BF4 crashes after 5 minuets of game play

-GPUZ shows whichever card is in the 2nd pci slot of my motherboard slot only 1x

 

Things I have tried:

 

-Driver sweeper

-Beta Drivers

-Switching Card Positions (VT on top XFX on bottem)

-Switching Crossfire Bridge around

-The second bios on the VT

 

Things that do work:

-XfX does not crash by itself under load

-Both cards post into windows individually

Is the visiontek one crashing under load?

 

Try the XFX card in the second slot.

by itself?

yea

[JDS]

Try the VT by itself, just to make sure it isn't faulty. 

[Tama]

 only shows 8x in the second slot by itself

What temps are your cards at under load?

Have you tried downgrading to older drivers?

I did and it is crashing under load after about 30 seconds

I tried 14.4 which worked fine with the xfx 7970 for a few weeks now and 14.6 beta drivers, Which older drivers should I try

 

about 35c idle, under load display driver crashes and so does furmark/Games

First stress test each card separately in both PCI E slots to make sure its not a hardware problem. Then start from the latest drivers and if it fails try the driver before that one.

You need to monitor your temperatures at load to make sure your GPUs are not overheating.

VT running in the second PCI slot, also PCI 8x

NEW DISCOVERY

VT 7970 is idleing at like 47c it crashes as soon as it hits 80c on furmark

XFX 7970 idleing at like 26c it never crashes, takes about 15 mins to reach 80c and still doesnt crash

Should I dismember the VT and put new thermal paste?

[Tama]

this is the VT on the Top

Seeing PCI-E X8 is normal for your motherboard.

According to AsRock, your top-most PCI-E X16 runs @ X16 when the second slot is unused. The second slot shares bandwidth with the top slot. Whenever the second slot is occupied, they will operate at X8/X8.

Since your VisionTek HD 7970 is a new card, and is still under warranty, best to RMA it and get a replacement. You never know, it may not just be the thermal paste, it could be a defective card.

If it were a used card, I'd say go ahead and re-apply the thermal paste...but that is not the case for you.

Since you said you got the VisionTek card off ebay, I assueme it was used. Yuo might want to try registering it for warranty. If you can register it, you should probably just RMA it.

[hadesjoy72]

Hate to echo the advice of others, but they are right...try the RMA route before you dig into that thing.....

[winningsince1337]

Just thought of this but, try using software like MSI Afterburner to make a custom fan profile. Use it to force a high fan speed to see if the card still crashes under load. Could just be some weird fan setting that's not speeding things up so it causes it to crash.

This is probably your best bet.  No sense in pouring money into a defective card.

it is used I bought it on ebay for $165 when I said (New) I meant tat was the card that I just recently put in my system

I just put new thermal paste in , NO CRASHES and CONSTANTLY UNDER 60c YAYHAYAYAYAYA but its still running on PCI 1x when I have both cards in my system

I started gaming and saw serious artifacting, not just a few tears or colors but the whole screen was flickering every frame so i decided to replace the thermal pads on the Vram, Still having the SERIOUS flickering artifacting jitter thats going on, as of right now games would be unplayabl is there a driver issue or something i should fix?

Considering how the card was already crashing and overheating before, it's probably dying.
