Once overclockers will get their hand on them and put them to work, we'll know exactly how most of them clock...

We are talking stock voltage here. You can pump voltage into anything to help its clocking potential. I can add jet fuel to my snowblower and it will sure as heck increase its output...until it goes kaboom.Quote:

Quite the contrary I'm afraid. If hwbot is any indication then we can say most 5870 cards w/ stcok vcore get 950/1250, or an 11.8% and 4% overclock respectively. While that might not be spectacular, it is far from a poor OC with stock voltages IMHO.Quote:

5850 OCed with stock voltage is a good idea, but 5970 Oced on stock not so much IMO.

Memory, yes it overclocks well. The cores? Not so much.
No. Because its fuel consumption increase could be likened to the cards' increased power conumption and heat production.Quote:

..just because some people don't know how to really push these cards, doesn't mean they are bad overclockers, it simply means that some people don't know what they are doing..Quote:

so ill take review sites and overclocking with a grain of salt :)
EDIT: i do see u understand it takes more voltage to get anything nice from the cores..but its to be expected with this card since its under clocked and volted to meet the 300w tdp
I believe it. ~780mhz @ 1.09v, ~850mhz @ 1.16v, and ~1000mhz @ ~1.3v with air cooling.Quote:

Jet Fuel is nearly the same as Diesel fuel. Chances are your snow blower wont even run at all :p:Quote:

a low voltage cpu also sucks at overclocking, but somehow anyone who gets one knows to first up the voltage to normal levels before OCing. why is this seeming like such a harder concept?
Yeah, I bought it along with the other 2000 people that enjoyed ATI's huge stock dump just before the launch =))Quote:

The voltage scaling and the negative temperature scaling are the ground stones of overclocking. You seem to have the feeling that every chip scales with voltage in the same way, and you keep repeating that. I don't even think I have to adress this ideea...Quote:

But since this is XtremeSystems, not mildly-stock-volts-systems, and overclocking usually means something a little bit different here, try to be more specific when you adress issues like overclocking.
i dont think anyone is saying that they dont clock when volt modded.
bah duel cored cards you know what to expect anyway.
thanks monstru for reply
btw
my comment was torward eastcoasthandle
Put these puppies on water! Until then I'm reserving judgement on their clocking abilities because face it, the stock cooler isn't up to the task to master 2 R870 cores at high clocks ( using stock cooling, I could burn one up in the Vantage feature tests I assure you ) Are the EK blocks shipping yet by the way?
cowie - I know, we posted at the same time :)
chickenfeed - this is the funniest part. This is the only high-end cared where I reached the maximum voltage that is possible to adjust by software, on air, and I still have scaling :) Of course, this is not for daily use, I am talking for benching and such. Anyway, this week I'll make some time to vmod the card and put it under some LN2, to see exactly how bad it clocks.
How does one just decide to vmod the card?
Is it the same on all different models of cards or just easy to trace out what you need to do by looking at the board?
Depends on the card.
if the tech documents are available for the VREGs then its pretty easy. If not then you get out the probes..
Bingo.Quote:

If anyone recorded ATI's presentation, fast forward to ~minute 40 and listen. I can't remember which slide they were presenting at the time.
