**Gigabyte Super OC GTX 480's - VERY LOW PRICES!**

In bios i recon you would need to do that surley ?

Cant see AB option to up the PCI-E V's

EDIT
By the way do all you peeps use the FORCE CONSTANT VOLTAGE option in After burner ? mine is ticked

I have been having some odd issues with the 480 SOC (see this post http://forums.overclockers.co.uk/showthread.php?t=18269451), I have ran the OCCT GPU test several times on 6 minutes and get anything from 0 to 500+ errors. On the standard test it's at over 100,000 after 15 minutes.

I spoke to OC Tech Support and they suggested a few things, so trying them now.

The odd thing is the artifacts only appear in game, when the GPU is being pushed by Heaven or Furmark all is fine.
 
Hey everyone, my first post but I thought I may aswell report my findings regarding the 480 SOC.

Got it on Wednesday and spent most of the day testing this is what I've found:

(All tests running at 1680x1050 on Dell 2209WA)

Furmark:

Settings used: 8x MSAA, Xtreme burn in
Observations: I couldn't really notice any artifacts.

OCCT:

Used both 3.0.1 and 4.0 beta 5

As you are all aware OCCT really pushes the GPU so I'm sure you can guess what I saw. Thousands of errors within 3 mins. Didn't really run this for more than 5 minutes at SOC speeds as temps were getting really hot (97+).

I got more errors in the older version than the newer.

Heaven 2.5

I don't have Windows 7 yet so unfortunately couldn't use DX10/11 so I was restricted to using DX9.

Settings used: DX9, Shaders High, Anisotropy 16, AA 8x

Observations: I noticed multiple artifacts/tears mostly during the first part and when the camera pans around the ship. What I also did to be certain I wasn't just seeing things was during the run I would hit 'Space' to pause the camera and just watch for 30secs-1min and I saw multiple artifacts. They're impossible to miss like this.

Another thing I noticed is sometimes during the run in DX9 the textures are all messed up. Not sure if it's the GPU or just Heaven but I have a screen comparing the messed up textures to what it should look like.






MSI Kombustor:

Settings used: 8x MSAA, API DX9, tried it both with and without Xtreme burn in enabled.

Observations: Within 2 minutes I get multiple artifacts/tears- very hard to miss. I also managed to get a recording using Afterburner. Quality is not the best but it does the job.

I understand that OCCT is really harsh but I'm not going to fault Kombustor. Also Kombustor is powered by Furmark but I think it's just much easier to spot errors in Kombustor vs Furmark so even though I didn't spot anything in Furmark there very well could be errors. Who knows. Too many colours and moving things.

All the above tests were run at SOC speeds @ 1050mV

PSU is a coolermaster 650w extreme power.

When running the card at stock 480 clocks all the tests come up clean. I ran OCCT for a good 5 mins without any errors so not really stable at 820/1400/1900. What do you guys reckon?

Click to expand...

well the default voltage for the SOC is @ 1060mV so I would recommend you to try running that.
 
could be your PSU - its quite borderline power wise

could be the card

try blowing a fan across the card - or suckinga cross the card - I'm getting dramatically different results with my card now with a side fan installed than I was previously

for instance >780 I couldn't run above 1900 memory, not one iota - no matter the GPU volts

now >800 core I can run 2000 on the memory with no artefacts in Heaven
 
btw I keep harping on about a side-fan but only as in my case its made just a difference

to note I had previously - last few weeks tried Heaven etc without the side panel on at all

what seems to have made the difference (it still doesn't run at 1.038V - but its much better than before) -is having this side 120mm fan (exhausting)- which happens to be almost right next to (a few inches away) the graphics card

the memory now is far more overclockable than before
 
If your card runs fine at stocm then the chances are its a faulty factory OC.
It coul also be ur PSU. I would suggest buying some crappy PSU from PCWorld and testing it and then returning it to them sayin it broke. If your card works fine with two PSUs then by a decent one from overclockers. Otherwise RMA to Gigabyte.
 
I still think there could be a temp element as well though

as I get the feeling >83C or so - the cards need more juice

just my findings so far - certainly with a 10C drop in temps on my card - I need lower GPU volts than I did before - quite a bit lower in fact
 
My 'stock' voltage was 1050mV. I have also run it at 1063mV and I got some artifacts in Heaven (less than when @1050mV). I went one step further and ran it at 1075mV- Didn't see any artifacts in heaven although Komustor, 8x MSAA and Xtreme burn in on, I got some artifacts. Temps were also much higher which kind of defeats the purpose.

I am doing a new build next month anyway so I may just buy my PSU early. Although when running the card at 1075mV with no noticeble artifacts in heaven makes me doubt it's the PSU.
 
I thought similar AzZ -but it could be that if your PSU is being pushed to max the 12V rail is drooping slightly

and it could then be that raising the GPU Volts could sort of compensate for that droop

thats my viewpoint anyway

put it this way - when I sent it back to Gigabyte they ran 3 hrs 50 (!!!) of Furmark - at 1.038V, 820 core, max temp of 74C (on a bench though)
