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

I think artifacts on 1 or 2 particular test is not conclusive.

The card is:
*not a reference design & uses exotic power methods
*shipped with a far from reference BIOS
*when tested at higher clocks, the drivers fail & not the GPU
*PSU/amps required are unknown, so only a 1k PSU can rule this out
*may need extra case cooling due to being pre-overclocked
*as it runs at a higher clock, then the death temp will be lower (as is the law of overclocking)
*the reference 480 design has been tried & tested over a year & there may be faults with the new Gigabyte design

Granted, when I get one of these babies on Tuesday & it wont do stock speeds at stock volts, then I'll return it as being faulty. Which it is.
I have good case cooling & a descent 750w 12v/60amp PSU which could probably run a GTX590.
Are there any pre-requirements on the box? such as good case cooling/PSU watts?
If there are pre-requirements needed to run this card, then it would be advantageous of OCUK to post these the their website.
 
er .... in my case:

(1) immediate errors running OCCT - and at that point GPU temp was only 60C

(2) flashing textures, whole black flashes (like a cut in the screen) in Heaven- throughout

(3) missing textures when playing DCS A10

etc etc - obviously not stable

drop clock to 760 all of the above perfect. BTW as another test- kept core at SOC speeds and dropped RAM speeds to stock 480 speeds, and made no difference at all , so whatevers going on - its
related to the core clock

I'm sure it just must be that the card is not stable at the advertised SOC clocks

my PSU is a 700W Tagan one - but its a very high quality one and I'm sure not at issue - max draw from wall is only (only !!! lol) 460W

if you read around on the web - people having issues with OC'd cards out of the box is not that unusual ... and not just with Gigabyte - so again I question how they are tested

this guy got through 2 SOCs with errors according to him:

btw just in case it was power related I dropped my CPU clocks back to stock to reduce power use of system by 80-100W or so under load and made no difference at all

also I've kept an eye on 12V rail, and evenunderOCCT its not going below 11.6 which is well in spec

I have a 1KW PSU and my i7 doesn't have an overclock ATM.
OcUK have a 100. Maybe 10 are problematic.
The SE use the same PCB ets, i don't think that they have had any problems so far
 
^^ and other than it not running at SOC speeds the card is great otherwise

just a bit pointless if meant to be cherrypicked

and also means unless you use afterburner, its no-way stable :(
 
ok heres a fraps vid - slow downs etc are because of a few layers of conversion - but the artefacts are still visible- worst are when you are zoomed out side of the blimp

ok video was too large - so ran fraps screenies o ver and over again and finally caught an artefact- difficult to catch as they must flash up milliseconds in duration, obvious to the eye b ut must be very quick

this is a small one - but you can see the issue

sometimes they are 10-20 times the width of the one shown here, sometimes vertical, sometimes textures are blue instead of their normal colour etc

on screenshot see through the wheel but if you can imageine you're probably getting a few of these every seconds all over the screen randomly ...

yup you're right

I did some searches on my PSU and one reckoned this split after talking to Tagan customer support- have no way to verify if correct or not - but worrying if correct - its quad rail - each 20A - but if both my PCI-E are being powered off same 20A rail ....

just to make sure I'll try the adapter in the box, and try one of the powers off 2xMolexs - in that case it would definately split across 2 rails

12V1 for Molex ,FDD,SATA
12V2 for CPU (P4,P8)
12V3 for M/B (20+4Pin)
12V4 for PCI-Express

Did you say your psu was 1000w

Which brand

Wondering if my artefacts are card or psu about 90 percent
Sure graphics

Silverstone ST1000f.
I know it's reliable and working because it supported my 6970

So are these 480 soc's problematic?

Are gigabyte off loading sub standard stock at cheaper prices?
Click to expand...

Not all. We're just the unlucky ones
 
Im tempted by the 480 soc, but i've held off atm due to people's problems. I was going to get one for 3D visison. I may just put a little extra to and get a 570.
 
I agree just unlucky - agreed that its a great card and well worth a purchase

hope OCUK have enough for replacements for us though - I thought end of last week they were almost out of stock ....

I got excited 10 mins ago, plugged in the 2x Molex to 6 pin in instead - to see if a differentloadingon PSU would make a difference

went into Heaven - no artefacts !!!! wow - hoorah

except then realsed I'd clicked on "keep overclock" (well underclock in my case!) in afterburner and card was running at 760mhz :( at 820 same as ev er with number of artefacts

RMA then :(
