GTX 980 increase Vram voltage Bios Tweaker

[Cryptonite]

Hey guys,

 

So I have this GTX 980 (not the one in my rig) and it is causing some trouble with red artifacts the artifacts only appear once in a while in some guys (batman Arkham knight) but in games like CSGO it is very constant. do you guys have any idea how I can maybe try to increase the Vram voltage using a bios tweaker to see if I can maybe make the Vram a bit more stable even if I have to underclock it. I've tried to underclock the Vram but it doesn't change anything really. I've got a feeling this is permanent damage (it's not too bad but still very noticeable in some games) and was hoping upping the voltage a smidge might just help the Vram out.

 

also side note, I thought Arkham knight wasn't going to support SLI? when I sli'd the card with mine it showed I had 8 GB Vram (wait Vram doesn't stack??) to work with and the performance maxed out was a constant 90 fps (game limit)

I think anything other than core voltage tuning can only be done by the more exotic pcb designs like the msi lightning series.

not even through a bios tweaker?  I'm desperate to fix this thing to give it to a friend, however if I can't fix it it'll have to sit in my second rig for the time being

Fairly certain. When I was making a custom bios for my 780 ti I didn't see a tab for mem voltages... Only core. This is assuming you are talking about kepler bios tweaker. I'm not well versed with the other bios tweakers.

I was talking about maxwell bios tweaker but it works exactly like kepler's so yea  outa luck I guess

Are you certain the artifacting is to do with the memory?

you think it could be the core clock? The most common problem with artifacts is Memory, but I am certain it is the GPU. I've tried it on 3 different rigs, mine (which has the exact same model card) and it does the same even if I go into MSI afterburner and downclock both Core and memory clock down to the minimum.

I'n not sure what exactly it could be, but yes it would have to do with the card itself, as I dont think drivers could cause artifacting

I already ruled out drivers already, went down 350. smth and it still does the same, I reinstalled windows on one pc just to check and it didn't change a thing so yeah, definitely the card itself as my card works on all 3 rigs without a problem.

Is it a used card? and is sending it for a RMA out of the option?

yeah RMA is out of the question, it comes from a guy that bought it directly from America.. this same guy had 2 980 Ti's (kingpin ed) and one of them is dead atm, it powers on but no display and if you plug a display in there the mobo's PCIe fail light stays on and it won't post . that card he can still RMA.. I'm starting to think EVGA sucks since the card I have is also from this guy and mine's fans just stopped working (same happened to the one with the defect, the defect happened only after a friend of mine got it and the fans also just stopped working) I took a fan from an old coolermaster small form factor pc I have and broke it to fit in the 980s fan area, and took my fan from my old 560 and put it in the other fan location and it's been working fine ever since   I got it with the broken fans though, so I can't say that the fans died on me personally.

You should call Evga and maybe contact the guy you bought the cards from for the original purchase order. One of my Water cooled Evga 980 ti cards got wet and shorted out. I couldn't boot my system with the fried card plugged in.  I called Evga and told them it was my fault.  They gave me an RMA # and replaced my card.  As far a Evga Sucking....my guess is your cards have been put through the ringer, maybe taken apart, water cooled and heavily overclocked, put back together and shipped overseas. I'd call EVGA, they are well known for their outstanding service.
