Lo
I've started an RMA process with overclockers for my 4870X2 which I bought from here about 18 months ago, but before I send it back I want to gauge a few opinions. I don't want to go through all the hassle and cost of returning a card to be told 'it's not faulty' and then just be annoyed and have a mare.
(It's a powercolor card by the way, and apparently their UK warranty is non existant hence I'm going through ocuk for a possible replacement which they seem fine with.)
Anyway, problems are: Various graphical artifacts/ corruption on SOME 3D games and benchmarks. No corruption on desktop or anything else (yet).
Symptoms include:
1. Tiny green pixels/ dots that quickly flash around in some games eg. observed in GTA 4, Lock on Flaming CLiffs 2, Mass Effect 2, 3Dmark Vantage
2. Somtimes bigger green 'blobs' that flicker more slowly. There will be less of these and are usually more 'fixed' in place. Most observed in Lock On FC2.
3. Somtimes bigger red/ purpleish blobs appear. These seem most apparent in loading screens for games eg GTA4.
4. Sometimes texture corruption eg small 'squares' of missing texture/ white eg in Assassins Creed or flashing texture areas eg 3Dmark Vantage
5. Sometimes polygon/ texture weirdness - eg like weird lines coming off a tree (long thin triangle shapes) eg in Crysis Warhead. I used to see this effect years ago on my Nvidia 6800 when I overclocked it too far.
Things I've done/ tried:
1. I've tried catalayst 9.12 up to the latest 10.3 officials and a few of the latest betas. I've tried using normal ATI uninstaller, and tried driver sweeper and ccleaner, and even reverted my system via restore to about 5 weeks ago when I'm sure these issues were'nt happening.
2. Took the card out, cleaned and reseated
3. Made sure temps are all good. Case is well vented antec 900 and I use rivatuner auto fan settings for card fan control. Never gets above 76c when gaming and idles at about 50c.
4. Card is not overclocked at all. Never have and never felt the need with the 4870x2. I've tried underclocking the card and symptoms still there, though perhaps slightly less.
From research I've done it sounds like a memory chip or one of the cores might be starting to die?
Anyone have any advice/ experience of these symptoms with ATI cards (partic 4870x2?)
What's bothering me most is, problems only seem to be in SOME 3D GAMES/ BENCHMARKS.
NOTE: nothing has changed with my set up and the symptoms have been noticed for a few weeks only. Card has been fine and dandy up to now.
My other PC specs by the way are:
Win 7 64
Asus p5q pro MB
q9550 oc'd to 3.7ghz
4GB ocz ram
Power supply - Antec truepower trio 650w
