ATI 4850 Hot fix drivers released

[Adhesive]

Drivers are a major issue for ATI right now. SO much so that I've almost gone nV a few times now...alot of games got that damn splash-screen...but I remain faithful that somethere is capable, or they hire someone new!





EDIT:



Why? Gpu should be good to 115c or so. Seriously. Throw it under some water and enjoy 30c temps if it worries you that much. For real, man.

Don't get me wrong, I'm actually thrilled that it only hit's 82c under load. The x1950 that it replaced would hit 97c while gaming...but I'm just not comfortable with the thing radiating 180f of heat into my PC throughout the day at 0% GPU activity. It's bringing the ambient temps of my case way up, and that can't be good for the other weaker components.

The reason it runs hot is because of lax fan profiles.

Pretty much all cards since x800 are this way.

i removed the shrouds from my 4850's the little plastic covers anyway, retimmed with ceramique and I setup 4 yate loons blowing over the cards, my idles dropped to mid 50's from upper 60's low 70's.

I still hit low 80's gaming though, i love the setup, sniffing 27k in 05 with stock cards and 4.1 wolfy, cod4 screams at 4axx 1680x1050 with max settings. I want better cooling though, only downfall of these cards, anyone know what coolers will work? Looks to be the same as the g92's and 3870's mountwise, was thinking some copper zalmans might do the trick.

I guess i will try this hotfix, so far I have had no issues in anything though.

[Macadamia]

HR-03 GT + A decent fan. Better than a Zalman, no exhaust path though.

Any "microstuttering"?

[Rattle]

no just played cod4 for a while, smooth ass glasss, I got an accellero s1 rev2 i gotta try too.

[Helmore]

Or something like this:

Curiously though, aren't idle 2D clocks supposed to be in the neighborhood of around 300MHz. just like the 38x0 cards? Oh well, we will know for sure in about a month from now.

[Rattle]

I have one those gonna try it, my cards go to 500mhz at idle.

[cegras]

Clocks don't matter so much as the voltage.

[STaRGaZeR]

Wrong talking about RV670, frequency is almost the only thing that affects power consumption. And looking at the idle vs load voltages I'd bet RV770 is the same. I will confirm it when I get mine.

[darkskypoet]

Well.. Mine too sits at 500mhz, which is high for 2d... Also fan isn't even working hard. Seems similar to my 3870 that I had... Fan set to be silent, card bakes... But no stability problems... I just used riva Tuner on my 3870 to turn up the fan if i felt like it. Be nice if that was simply part of CCC. Set your fanspeed at various temp points.

Honestly, if its an issue much like with 3870, just turn the fans up with riva tuner (hopefully supported soon).

To answer someones question from above, DVi works fine, DVI to HDMI is fine. Driving a 22" @ 1680 x 1050 and a Samsung Series 3 at 1920 x 1080... (strange as its supposed to be only 1080i, but my 3870 in xfire drove it at same res)

[Power5]

Yeah, wish CCC had programmable fan profiles. I set mine up with riva tuner on my 3870 and it works great. Set my idle fan to 40% which is still silent, and it kicks up at preset temps to 100% at 85c.

I've seen this mentioned before. There can be only one explanation for this and that is that the voltage does not really change.

[STaRGaZeR]

I've seen this mentioned before. There can be only one explanation for this and that is that the voltage does not really change.

It does change, confirmed with a DMM, idle voltage for RV670XT (HD3870) is 1.241v and 3D voltage is 1.327v. Miwo, myself and lots of people have tested this and it's a well proved fact. The key to reduce power consumption in RV670 is to lower frequency, lowering voltage has virtually no effect. And it seems RV770 is the same. I don't have an explanation, but it happens. Maybe they disable some parts of the chip at low MHz, who knows.

[Miwo]

lol I love how Stargazer is so quick to jump in on any of the power consumption talk about the RV670

I think that AMD needs to fix some crossfire profiles, get those latest games supported as soon as they can. Dual RV770s in Crossfire are a pretty damn attractive alternative to having a single GTX260/GTX280 considering how many people have Intel chipsets on their boards. Personally I'm awaiting to see the performance numbers on the 4870 before I jump on the RV770 bandwagon. If the DDR5 bandwidth does barely anything, I think ill jump on one or two 1GB 4850s now that I have finally retired my XBX2 rig and have something a little more up to date. We still need some more OC Tools that support the RV770 to make full use of vmods though and overcome the CCC limit. When I get one, ill be sure to jot down some kill-a-watt readings on both idle/load at varying voltages.

[STaRGaZeR]

We need to sticky it, every X time someone cames with the same "it's impossible, voltage should have more effect"

[SocketMan]

I have His 4850 and it looks like the BIOS is missing 1 (maybe more) of the
"power levels" there should be one ~160mhz and the corresponding (low) voltage,however the "lowest" "power level" is set to 500 and the not so low
voltage.

There are 2 BIOS files there 1 MSI (with correct power levels) the other one
is Powercolor with "messed" up "power levels"(like my his)

You see, there was something wrong with that power consumption. 160MHz core

To say the least,^^
75c idle is ok for the winter but not summer
I wonder how many reviews out there measuring the "idle"
speed incorrectly. Looks like a BIOS update for many 4850 owners in the near future Oh well
need to pay the price for being the Guinea pigs
