Zotac 970? - Page 18

It's pretty clear I'm limited by power here and it's not going to hit 1500mhz until I can unlock the power limit. but thanks for the help.
Not even the power limit??? The fancy Zotacs still have 106% power slider???

Keep in mind a card's power limit is relative to what it's respective max TDP is set to in the bios. The base Zotac 970 may have the same 106% power limit the Extreme or Omega has but they're two entirely different values. I don't have the reference bios so I can't compare but the tdp with 106% on the Omega/Extreme allows up to 345w. For more examples the ASUS strix @ 120% is 196w, the gigabyte G1 at 112% is 280w, so they're entirely different values and rather deceptive. The Extreme bios should allow for voltage control up to whatever limit Zotac imposed via the bios/firestorm software.

Well that might be the best thing I've heard yet. So if I'm understanding you correctly, if I flash my vanilla with the Extreme or Omega bios, I will be raising my power limit even though it'll still show 106%?

Just crossed my mind the Omega and Extreme have vastly different components. Not too confident I can use that BIOS. I might try though. I'm getting desperate to increase the power limit on my card. I'm damn near at the ceiling with stock clocks.

rv8000, well that is very interesting. If I read you correctly that basically means that each card model has its own different wattage curve for the percentage slider. In the case of the Kepler BIOS tweaker, is the curve linear between the different percentages?

The Omega and Extreme have identical pcb's and components, the non-amp Zotac 970 does not. DO NOT flash your vanilla with the Omega or Extreme bios, wait for a custom bios/new nvfash unfortunately.

I'm unaware as to how Board partners decide on the power limit % as opposed the corresponding tdp. The number seems arbitrary when you look card to card, but there isn't a "curve" per say it is simply percentage based.

just sent you PM... disregard that. This is agonizing. Under water my thermal limits are clearly not an issue and I know this card can go so much higher. I just neeed more power!

I just bought this card and I got 2+3 years warranty.
Apparently it's a ref board and the RAM chhips are all the same side unlike EVGA's ref 970



The PCB design has been super recycled since GTX670

Very nice!!!

@DevaLT
Are these small black heat sinks your mod or it is default as I saw on some other pics a bit different heat sink on Zotac GTX 970?

Best, d.

Nope. that is the whole VRM heatsink not small pieces badly stuck together

@DevaLT

hmm that's funny. This review shows different heat sink. I also checked mine now and has same silver smallish heat sink. Yours seems like it is stuck on the VRMs.
