wow.anyone dare to test ???

I just picked up my second 5870. What I would like to see is a beta driver release for XP?

No use. XP is obsolete now. I suggest grabbing the RC of Win7 from somewhere if you REALLY hate Vista. That should hold ya off till the 22nd.

[Robilar]

I don't hate Vista. I just haven't seen any point in leaving XP. When a game finally arrives that forces me to upgrade to Vista or Win7 I will. Until then what is the point? I don't see any real benefit to being able to run Vantage...

In my opinion, an OS should be in place to run programs. I don't care about graphic tweaks, increased security (I have programs for that) or any of the other bloatware options included in Vista. Win7 is supposed to be an improved version of Vista but improved for other users.

On a side note, XP is far from obselete. The company I work for and many of the largest companies in North America still use it exclusively. Heck, most of the Canadian banks are still using Windows 2000.

That doesn't make it right. Its time to drop XP. As a long time XP user and Vista hater, Windows 7 is a great upgrade. I love Windows 7 - but I hated Vista. The best reason you have to leave it - you bought a brand spanking new card that is being held back by your OS. Its time.

Hardwaredeluxx is testing that 5870 to 5850 modded bios, here is a screen. (1440 shaders at 850/1200 default clocks)

Don't know about that, have a look at this German one, claims to have an unlocked 5870 bios on a 5850.

[Patch]

nice, well try to oc, then i'll compare with asus bios.
[/IMG]

The 1800/2600 BIOS seems to do OK with clocking compared to the ASUS BIOS, but there is a weird stutter on the desktop.

Vantage bench (CPU at stock with speedstep on) is pretty similar to what I got with ASUS BIOS.




I haven't decided if I like it yet.

On another note, anyone found drivers that allow 5870 quadfire yet?

I used yesterday's CCC release and it will briefly enable all 4 cards, but always disables 3 of them after 5-7 seconds. Multiple reboots and several fresh installs gave the same results. Trifire works.

[Rattle]

Seems like they pulled them.

Here are newer drivers anyway. Cat 9.11 beta (Win7/Vista only)

http://download2-developer.amd.com/a...vista-win7.zip

anyone else have problems with these drivers? I tried them and got weird 2d text and blurr, even in 3d games everything looked ok but even text in games was all blurred and weird...

Grabbing popcorn

Did someone flash the 5870 bios over a 5850 card & it killed it?

Btw; I hope to learning more from you all & getting questions as I've just picked up my own XFX 5870

http://hdimage.org/images/ahnwlylctdl0b6o0vfff.jpg

Btw; I used search & google for switching from ATi - Nvidia & vice versa. I believe the path I'm taking is control panel > uninstall > driver cleaner > install card > Flash Asus Bios > DL Msi AfterBurner > Start Oc'ing

Correct.

Anyone know a program to monitor vrm temps for 5850? Gpu-z only shows me the 3 core sensors. Would love to know vrm temps on stock b4 i switch core 2 water.

AMD GPU Clock Tool will show the VRM temps of the 5850.

[Sgt.McRuff]

AMD GPU Clock Tool will show the VRM temps of the 5850.

Well erm, huh. So around 48-51c for them with voltage at 1.175.

I have a interesting limit. How to explain? So if i use 1.2 volts using msi afterburner after about 10-15 mins at STOCK SPEEDS it will artifact(using ati tool). Now its not temps, its under water for the core and its around 36c.
If I do 840mhz with 1.2v it will artifact almost instantly. setting it to 1.23 will cause it to artifact with no load. yet 1.175v i can hit OC of 975c (furmark) or 970c (atitool)

The power parts of my 5850 is a lemon? or faulty?


My OC: 1300mem
1.088v 840c air and 860c water
1.15v 940c air and 955c water
1.175v 960c air and 970c water

the 40nm process has leakage, and some gpu works better under lower voltage especialy under water.
that is one explantion.

[ieatrawbacos]

What kind of cooling is on the memory/VRMs? Have you tried a lower memory clock? Is the GPU die making good contact with your water block?

I'm on the stock cooler, and my clocks continue to scale all the way to 1.3v+. Most other people are reporting similar thing. Cyprus doesn't do better with lower volts.

[Monstru]

Patch - 8.66 RC6 (the original beta driver) works with 4 cards. I tested them here.

Regarding that 5850 with 5870 modded bios, from what I know the shaders are hard locked, so no chance in unlocking them with a bios.

Sorry for waiting, we finally finished 5850 unlock BIOS with higher CCC overclocking limit.

Finally heading to bed; Stopped testing @ 975/1275 @ 40% Fan Speed - 75C avg. temps. Just love this card, very glad I got the purchase. More to come later ...

[jfer]

Oh man! Im trying out the 5850! Right with GPU Tool:
core: 875
Mem:1250

It beats my prior 4890 crossfire setup! Im getting upper values in every game comparing it to 5870!
Im gonna put it on water next week....

msi unlocked bios 5850.
flashed and run 3dmark06, 4.2ghz i7 and broke 25k
1020/1200.

edit: powerplay is acting up to for 2d, as I got 2 screens i get some flashing textures in 2d setttings.

[jeanjean15]

is anybody owning the asus 5850 can tell me if he can increase gpu voltage with msi afterburner ?

Thanks.

Im going to keep telling myself that. I can live with leakage, but not thinking something on my card is broken.

I'm on the stock cooler, and my clocks continue to scale all the way to 1.3v+. Most other people are reporting similar thing. Cyprus doesn't do better with lower volts.

Stock plate + some small heat sinks on the heat pipe for vrms, they seem much cooler than my 4890 which had same setup, from touch to temp software. Memory was test at stock speeds 1000 for voltage stuff, even though its good to 1300. I did a test contact with swiftech mcw60, contact was great. But of course after realizing the problem I took mcw60 off and checked, was perfect. A nice thin white transparent layer of Ceramique.

BTW I took off the small heat sinks on pulse chips b4 putting it in.

Oh yeah!

With this bios, you can use afterburner for everything on 5850; with asus bios you can use afterburner for everything on 5870.


Unwinder made a note at guru3d about using self-modded bioses that aren't directly from a manufacturer (stuff you edited in RBE). He says "Reference design board and original AMD / NVIDIA VGA BIOS is required for proper voltage control on these cards. Voltage control may work improperly if voltage control circuit on the PCB or voltage table in BIOS is modified by manufacturer or by user"

Using this 5850 bios or the ASUS 5870 bios will be fine, they have hash + signature & standard I2c dump. Little overboard on the 5850 slider limits though... lol.
