New 480 SOC Not Stable At SOC Clocks ?

[LanderTaker]

Hmmm... droped timings to 700/1400/1848. Same behaviour with alien vs predator DX11.

Weird.

Testing other q6600 and memory timings...

[LanderTaker]

Tried q6600 with 343 x 6 (fsb 1:1) and 266x9 (fsb 2:3) with identical results. Auto voltage.

Set all the values to what a reference card would run ( clocks and voltage ) and try if it runs ok. If not, increase the voltage a bit and check again.

Another option could be faulty RAM ( not VRAM ). Run memtest and see if it shows any errors.

If the card's still not working properly after this, RMA it. Eventually check with some other card to see if it's not something else dying.

Yeah, as stated, same results.

How can I change the voltage of the gpu??? Afterburner have this value fixed (Neither show any value!)

I have passed a windows 7 memory tests without failures.


It is weird that an stress tests (kombustor and orthos) go fine and crisys 1 and alien vs predator fails... :S

As I said before this is a problem that occurs with some cards and I think your best course of action is to RMA it.

[LanderTaker]

Okkk, thanks a lot!!!! I will tell the shop about the problem!!

[Dark Mantis]

Please let us know how you get on with this issue.

[LanderTaker]

OMG!

Today I have tried to just start alien vs predator with DX 9 instead of DX11... it works. (I have been playing some DX9 games without problems, so not weirdness here).

Later I tried with DX11... it worked!!!!!!!  O_o

After that test, I set the OC as it comes as default... Tried the game again... and it works o_O

what the... maybe some type of windows patch? O_o

what the... ¬_¬

Trying again... maxed the game... completely, antialiasing x4, anisotropic x16... it is working O_o

yesterday the larger time I got to play was 1 minute... ("the hunt starts" "kick your firsts alien!!" you kick him a little... FREEZE!!!) but now I am playing without any problem... :S and with the OC from gigabyte :S :S :S

I have observed a difference:while playing the second monitor is black instead of the windows desktop screen with the nvidia system monitor and afterburner in it


Temperature: max 85 as stated by afterburner!!




hmmmm... have the gpu got scare after I sent the email to the shop?


I will do more testing. Ah, I am going to try crysis a bit more...

weird O_o o_O O_O


Tomorrow I go on vacations... so the tests will continue in 10 days from now...

Computers have this tendency to sometimes behave oddly. I've long since given up on solving some issues I've encountered .

[Dark Mantis]

Yes sometimes there isn't any visible reason for these things. Maybe it just knew you were  not taking any more sh1t !

as OP of this thread - I thought I'd update it:

Bought 480 SOC- artefacts everywhere in OCCT/Furmark, artefacts in Heaven - very obvious

only thing that would make it stable was reducing clocks to 750/760 ish

sent back to Gigabyte - who tested it - apparently very thoroughly - NFF - stock volts and stock SOC speeds - 820 on the core

after that I suspected that it must be my700W Tagan being underpowered

so bought a Corsair HX850 - which is plenty powerful enough and very high quality.....

same artefacts - no better and no worse

really annoyed now - as wasted another £110

any ideas ?

lots seem to be having issues so something very wrong somewhere

I'm tempted to pay for it to be independently tested

[Dark Mantis]

I would say that it sounds like whoever tested it wasn't too concerned at finding the problem. There are many of these cards around with a similar issue at the moment. I would suggest that you try it on a friends machine first. It seems to be down to the voltage settings on these cards usually.

[Buckster]

Dark Mantis - thanks forr reply

the screenshots. photos etc (about 15-20 in total) they sent me - convincced methey'd tested pretty thoroughly

which makes it even odder

I will try in a friends machine when I have a chance

I even went up to 1.088V - but even at that I couldn't get 810 stable-let alone 820,  ok it was far more stable than at the stock 1.038 - but still nowhere near fully stable
