STILL Artifacts With 7970 Lightning boost edition

[alterlai]

Hello everyone,

You might remmber me from some other topics talking about some problems i have with my 7970.

I'll some up some problems i'm encoutering since my purchase:

1. Random artifacts in gaming:

I get random red flickering and bars through my screen.

2. Random artifacts when using web browser / wathcing videos.
Whenever i'm watching a video colored bars flicker in my screen, even when it's not playing.
Whenever i'm browsing the web i get random white block in the webpage.
example:

3. It will randomly super underclock the GPU.
When i was playing civ the other day it will just freeze the game. So i was monitoring GPU-Z and i noticed it completely dropped in volts and clock speed, and then re enabling itself after about 10 seconds.

Here are some screenshots of the artifacts and GPU-Z.

Specs:
Intel Core i5 2500k
7970 lightnihg boost edition
Asus maximus iv gene-z
XFX 650W XXX Edition Modular PSU
Crucial M4 120 gig SSD
Seagate Barracuda 2TB

I have tried beta drivers, legacy drivers, reinstalling drivers, underclocking, overclocking. Without any improvement... 🙁

Anyone has experience with this kinda thing?
My experience so far with AMD IS HORRIBLEEEEEE.

P.S. Already RMA'd my first 7970 expecting a DOA card, but even with a new card, problem still exists.

Set it to run at 925 Mhz core clock, 1375 Mhz memory clock, and see if the artifacting still occurs.

If the problem goes away, it means you got a bad chip that can't run stable at the factory set speeds. Which is enough for you to RMA it (again)

They have to legally accept a second RMA right?
Do you think they would let me swap for another card, like around the same price?

Yes they have to accept the RMA because the card is unable to run as advertised (if you can prove it)

But normally the terms and conditions only allow you to swap for the exact same card. If you want another card you'll have to talk it out with the supplier providing the RMA service.
