so if you can get the Sapphire HD 7950 boost in local retail shops with the game bundle at 275 euros that is a option worth considering. thumb.gif

Dude, 1200mhz on stock? That is really good. I have that exact card and @1175mV, I can only pull 1150/1610. Anything after that and it gets angry and starts to artifact. I would pull the trigger if you can confirm the OC.

Oh I now I get it why you mentioned the bundle. I "forgot" from the excitement that this is a used one therefor no games.. lol! tongue.gif

You absolutely right. That's a worthy option to consider of course. wink.gif

Well, I hope this not again a "too good to be true" case. Here's hoping for those proofs I asked him.

I think 7970 cards have different stock voltages based on ASIC. Some GHz cards have a boost voltage of 1.25v, so 1200 at 1.25v is not so impressive. At 1.175v it's much better.

^Exactly. Its very annoying when people say stock voltage as it means absolutely nothing, so always assume it means 1.25v.

Very true. MSI AB reports my stock mV as 1.112 but idles at 0.945. I don't think I've ever had a card that was 1.25 stock. On both BIOS, this card reports 1.112mV. If he achieves 1200MHz with that, I'd be damn impressed.

Well glina and I were doing some comparisons.. his card take 1.187v to do 1200, mine take 1.137v for 1200.. but mine uses more power, so even voltage doesnt seem to mean that much.

Are talking about 7970 or 7950?

7950s, but my point was his card takes more voltage but doesnt use more power. Very weird.

On that account then yes, I see your point.

I dont have any hands on experience with the 79xx series but since your card need less Volt for 1200Mhz, how much is the max clocks for each other at 1.25v with lets memory at 7GHz? In again lets say Heaven 4 or Valley or Firestrike or games fixed benches? E.g metro2033, AvP etc.

I'm asking because I'm curious to see if the cards that need less Volt at the same clocks as other ones, overclock/reach higher clocks that those needing more.
