Sapphire 4870 arrived!

[dedgar]

Got mine yesterday and installed today. Running the GPU2 folding on it I have 84C temp.
Was initially having all sorts of BSOD's until I redistributed the power load. (What drew power from which set of cords.) Haven't had a BSOD in the last 3 hours. (That's the current record.)
So next month when I buy the 2nd one for Xfire, I'll also have to buy a psu that has four of the 6 pin video plugs on it.
It'll be worth it in my opinion.

dedgar, just do the CCC fan profile to lower than Temp down significantly!

While the 4870's Ramsinks are a little different than the 3870's, I wouldn't worry about them being left off. I like the cooler as far as aircooling goes though, since it ports it out the case.

Here's what the 3870's GDDR4 read from the sinks:

I'm going to replace the TIM with AS5 as soon as I get coffee filters.. I'm going to check out that article aboput speeding up the fan to. Even though, when the PC starts up that fan gets loud as hell, like a hair dryer...

Yeah it usually spins %100 or so at boot then gets back to normal. I think it's a test for fan failure.

It runs to 100% on boot because no driver has taken control up to that point. So that shows the driver is not prime time.

I think it's not a problem, but a marketing thing. If it was cool yet loud AND a dual slot cooler during a review, they'd get hit. On the flip, and being a constant thing with each release since the x1900, they can just fluff it off and say a driver will fix it. However, this might change now because we're all seeing them hot and not worried about noise as much as the heat.

I plopped the Maze5 GPU block on, and it's cooler than the 3870's were. I'm trying to find why that is, because that doesn't sound right, before going hogwild with it. So I'm ripping down constantly in my free time trying to make sense of that.

Yep all the cards since like X1k do it, but that just shows you how loud they can get.

As far as the heat goes, I'm sure ATI would not let the card run at a dangerous temp, however it's too warm for my liking and decreases overclocking potential.

I don't know, since the 7900 OC fiasco I prefer to just run things cooler if possible. :P

Well it'll run at high temps, its just it starts to artifact. I know i had my 2 4850s hitting 100 degrees and i was seeing green/red dots in WoW.

Yep tomorrow I'm going to get coffee filters so I can clean the TIM, also I could not figure out the fan mod by editing the .xml file, I couldn't find the file, I run vista ultimate 32 BTW.
