Msi 7970 Oc bad overclocker

If it's not too much trouble, would you mind having a look to see what BIOS version it shipped with and letting us know? I'd really appreciate that. I had some bios-related adventures last week and I can't be certain I've restored everything to factory condition until I confirm what bios version the latest 7970 OC's are shipping with.
Moar volts=higher clocks imo with the 79's-if you can keep it cool enough.
The lower Asic's have been the higher clockers for me-2 low Asics v's 2 high Asic's, but I won't argue the point as that it could still be down to the silicone lottery.
I too have had higher clocks with lower asic, the highest asic 7970 I had (~80%) was an absolute stinker, the lowest (62.4%) flew.
Have a 62.5 & 70.1 at the moment waiting for water, far too hot to oc on air.
@kissenger, do you still want bios?

If you don't mind mate. That would be very useful.
Which blocks did you decide on?
Found some Heatkillers in stock, are they decent or can I do better?
Heatkillers and Aquacomputer 7970 blocks were tested to have the best thermal performance (heatkiller was something like 0.2c cooler then the AC but thats splitting hairs).
EK had the best flow (by quite some margin).
So either EK, Heatkiller or Aquacomputer, can't go wrong with any, I would throw in swiftech Komodo's into the suggestion box but they're like gold dust in Europe. Pretty much the same situation you had with getting Classy blocks, Swiftech can't like us Europeans or something
As for my choice, its a little up in the air, I wanted heatkillers or Aquacomputer, but they aren't very forthcoming in what size screws they use. I need blocks with M3 threads due to the backplates I want to use, currently only know of EK and XSPC using M3 standoffs on their 7970 blocks.
@kissenger I'll dump the bios tonight and fire you a link over in trust

Bundymania did a review.

Would like to contribute. I have to great overclocking cards from them. However, they are being held back by the memory ic on the third card. In no way can I get anything stable above stock. =/ I think whilst reading the thread, humbug noted that some people need to run in their memory ic. I for one have not found anything on the net about this. Is this true? The core is a bit slower than my other two, but overall great overclockers, minus the memory ic of the third card.

With Planetside 2, dispite it is 1440p with a 7970, you could still be CPU limited (think the game doesn't really benefit from more than 2 cores) in the large scale battles with lots of people duking it out at around the same area in the open field with a high render distance in such large maps. If you can edit the render distance to shorter, it should give you some noticable boost in frame rate.

HAHAHAHA, you people need to relise, most cards have there own branded bios on them that have lower and higher default voltages, there for when people say i can get this and that on stock voltage ask them what there STOCK VOLTAGE IS before saying WOW YOU GOT A UBER AWESOME CLOCKER THERE lol
SO meny people make that mistake thinking all 7950s and all 7970s have the same stock voltage. . . . the higher your stock bios voltage the higher you will get compaired to someone with a ref 7970 for instance or a boosted one, or a ghz one they all have diffrent default stock voltages to be able to get there in the first place.
ALso : ASIC Quality does not mean anything, all ASIC quality means the higher your ASIC the better your card can run undervolted or run higher on stock voltage compaired to other cards that can run on the same voltage...
ASIC imho does not mean you have a great card as i have seen lower ASIC quality cards that can overclock with the best of them.
Usually though like i said the better the ASIC the better your card can run on undervolted clocks.

No but what clocks it can achieve on stock voltage will give you an indication of how the card will shape up with higher voltages and clocks.
What is with the negativity? - You sound childish. I'm not picking fights or pointing fingers, but you'll find that attitude really isn't welcome.
Contradict your self much?
I agree, it probably doesn't mean anything - yet. That's not to say the theory is completely made up or false.
