Does anyone know anything about this.

hi all! I've a problem with my two gtx780 GHZ edition when in sli at stock clocks (factory overclocked)...All the benchmarks (valley, Heaven, 3dmark11) are rock solid but somes games like Chivalry, The witcher 1, guild wars 2 and Borderlands crash and i have to reboot...I ve tried the card with different motherboard and ram and still the same issue..Already tried one card at time, the first one work well, the other one give me TDR in registry and black screen at the same time when i play these games..I've tried to downclock to 966mhz and seems to be fine..The driver i used are the last beta, and 332.21 whql...Should i have to try skin3t bios before doing an rma?

I would not touch them if you want to RMA, just send back the faulty card. Plenty of people are having issues with Gigabyte cards right now, I had to send back my 780Ti for the same reason.

Any Gigabyte GTX 780 Rev 2.0 owner who could tell me if there is 4206 voltage controller on this card or not ? Basically if it's possible to unlock this card to higher volts than 1.21 ? Thanks guys.

Ok, so i think i will do an RMA to solve this problem...The weird think is that the card is 100% stable in benchmark like valley, heaven even 6 hours no artifacting or freeze/crash/TDR..Only some games like Borderlands, Chivalry, Guild Wars 2.. it seems that the boost 2,0 is broken or i don't know..I know that it's just the card and no other components because i've tried with other rig, but i'm just scared about the non-evident problem of the card..Can they see the problem and sand me a good card? Even if it's not stable only in some games (how can they see it without playining them?) Is that a way to be sure at 100% that my card is faulty ? Can you show me some topic/post of the gigabyte gtx780/ti ghz/oc problem just to compare the symptoms i'm suffering? thank you very much!

Its a non-reference card 8+2 phases NCP4208, LLC behaves erratically, Volt mod may or may not work! Up to you to find out! thumb.gif

I'am little confused now, picture I found says 4206 if I can read it right

(it's readable when original is shown)

And also I talked to other forum member few minutes ago who says that voltage control works on Gigabyte GTX780 Ghz Edition which has as you says the other 4208 voltage controller. On top of this all... I have Gigabyte GTX770 right now which has 4208 and I can't get more than 1.21V by any means.

So I'am thinking, how is it possible that it works on 4208 & GTX780 and it doesn't work on 4208 & GTX770 is it even possible ?

What do you think ? Thanks.

I think I should have specified...these cards aren't watercooled atm. I was looking for ones that didn't have to watercool like the evga ones. The ones i found from what you showed me said they have to be used with their waterblocks and can't be used with reference coolers.

Yes i can see that you are confused:



EDIT:

to understand this better:
NCP4206 manages 6 Phases for the core
NCP4208 manages 8 Phases for the core

Memory Phases are managed by other voltage controller (Usually its the Richtek 2-phase analog PWM labelled 0T=FG V1D) without I2C interface!



"And also I talked to other forum member few minutes ago who says that voltage control works on Gigabyte GTX780 Ghz Edition which has as you says the other 4208 voltage controller"

As i said in the other post: it may and it may NOT work! As ive had reports of it working and not working, The knowledge that the person is able to make it work or it doesnt really work for his card is beyond my control!

"So I'am thinking, how is it possible that it works on 4208 & GTX780 and it doesn't work on 4208 & GTX770 is it even possible ?"


You really cannot expect 2 different PCB's with different chips to behave similarly right? It all depends on the programming that was made into the bios/voltage controllers and drivers, if nvidia doesn't want you to add voltage to the 770 for some reason, you cant do anything about it as its coded in the drivers even if you have a hack into the I2C on the NCP4206/08 !
