7970 Voltage Overclocking Should I? - Page 5

post #41 of 68
I personally have had good success with XFX. I have owned 4 of them, but I have never altered them from the factory in any way. I was also under the impression you void the warranty if you alter the cards.

I have seen people claim they do not overclock well and I have seen people have trouble finding the right waterblock to fit the cards.

Well I plan on waterblocking them. So that won't be an issue. I just want to be able to overclock them.

They might not be reference PCBs this late in the game. Double and triple check that the waterblocks you're eyeing are compatible with the revision that you're going to be shipped.

I highly doubt theyre anywhere close to reference design this late in the game.


As far as warrnty being voided xfx suport themselves have told me that I could re tim my cards and it would not void the warranty regardless of the tamper seal on the screws. Ive saved those as screenshots in case they try and switch up theyre stance on me.wink.gif

I have the reference MSI 7970. I have the stock and MSI Lightning bios on my card and the Lightning is voltage locked.

Stock clocks were 925/1375 on 1174v and I'm at 1110/1600 on 1225v. I could probably get a lower voltage but I'm lazy to be honest.

Lightnings are not voltage locked at all. My lightning (as well as everyone elses) goes up to 1.35v on the BIOS 1

People have been telling me that they are made so they cannot be modified even if you flash the BIOS.

Is this true?

Who cares about the XFX card? I clearly mentioned in my post that I was talking about a NON XFX card. Just buy a NON XFX card and be done with it!
Many people have suggested what to do but you seem to not want to take their advice....

why must it be XFX??? Do you PLAN on ruining your card and needing to replace it under warranty??????

Really, just get an MSI or Sapphire, up the voltage, all good.

I did not say that the Lightnings are voltage locked, I said that my flashed bios is.

lol

Honestly XFX is the EVGA of the AMD world. Their cards are usually the best looking. (thats one of the reasons I went with them, length being the main reason)


I dont understand the anger. lol He wants a XFX 7970 so just help hime figure out how to overclock via BIOS flash or something.

The black editions from my experiances have a better chance at overclocking at stock volts.

They're the evga in so far as they're an exclusive partner.

In terms of quality? HECK. no. Got mad respect for EVGA
