reviewQuote:
We made a small test (3dmark Vantage) of a Radeon 4850 Crossfire System with the Catalyst 8.8 beta. We tested with a Intel Q6600 (3.8 GHz) and 4GB DDR3. The benches I've added. Look forward, the final Catalyst 8.8 can maybe a little bit better! The powerconsumption is the whole system.
driver
nearly 40watts drop in idle power consumption. :up:
Will drivers be able to low the idle voltage in the 4870? The 4850 can do it via BIOS, show us the 4870 :yepp:Quote:

That. Is. A. HUGE. Vantage. Jump.
And I thought by looking at 06 the 4850s weren't that potent...
Good increase in Vantage + great improvement in idle power cons.
I hope this driver package brings some game improvements as well.
Jedi Academy working (it wasn't in 8.7), Assassin's Creed crash on me in 1 minute. No improvements in idle frequency or power consumption (single 4870).
:2cents:
What cards you have?4xxx series?Are you sure PowerPlay is functioning properly(verify the clocks and voltage)?
Yeah me two the Assassin's Creed crash on me two I thought I am the only one. But I think I can play it about 30mins but actually it is pretty random crash. I don't understand why either so it is because of the 8.7 driver?Quote:

Anyone have a download link for these that isn't pctreiber.net? Their server is timing out, must have crashed.
edit: nm, links at the bottom of the first post work.
Where is that BIOS? The last one I have notice is the ASUS TOP which is .029329Quote:

You only see a drop in power consumption if you have a CROSSFIRE system. One card powers down at idle probably. There won't be any difference with a single card.Quote:

So are you saying powerplay will never work on the 4870's?Quote:

So you suggest in Crossfire with 8.7 both cards are at full clocks/voltage and with this beta one of the cards goes idle? That doesn't make any sense at all. And a 40W drop, 20W per card...Quote:

Anyone have any results, are these better than the 8.7's does CCC work in vista 64???
So the 40W drop is bogus?
I still get the INF error with ATI's drivers....... time to ebay these cards and get a single GTX 280
Finally got them to install after 3 tries, CCC still doesnt work under Vista 64, I can care less if anyone agrees, ATI's drivers suck a$$
This drivers changes pretty much nothing :)
Don't know about these but CCC works fine in Vista64 using both the hotfix and 6.7. with the 4870.Quote:
