Powerplay slipping into 2d while gaming...

[ATi7500]

Note that the editor does not change the low power 3d settings so it will go back to 300 core on load below 30%.

I noticed that the 3850's have 1.014 (or similar) for GPU 2D voltage. Wouldn't be possible to set that for 3870 aswell? Or is there a low limit in addition to the high limit when setting the voltage on HD3xxx series?

bYeZ!

You can set it to 1,014 but it causes great instability. Most games fail to launch. I have found that 1,214 is the safest for 3870 2d mode.

weird..but thanks for trying out

In my best babblefish german, I asked him if we could have it adjust the 2d and 3d powersave modes as well.

He speaks english well, babblefish isn't required.

He indicated that he had some serious issues adjusting the low power 3d setting. Daidlos maybe you could give him a hand?

We would all appreciate it.

Sorry but i will have to delay the release of my new bios as one of my cards died after a failed vmod. As soon as a replacement arrives i will test the new bios and if it works ok i will release it.
This time i will release multiple versions with different oc levels and fan control. Stay tuned!

you really are the man. i hope you know how much we all appreciate the work you're doing.

I tried your 800 @ low & high 3d, and 300 at 2d.

It works, but the temps are really horrible, i have to use ATI tool fan profile to avoid hitting 80c, where in the 3870fanfix.bin file i didn't use atitool and it would never go above 65c. And atitool is not good, and will go low/very high depending on temps, where the fanfix one would adjust very nicely with temp.

I was thinkin you could combine your latest one (800/1152 @ 3dhi/low) with the fan control from the one here.

EDIT: yah im gonna have to take that back. It helped on crysis, but other games like Unreal Tournament 3 just crash when they start. I flashed back to the one i upped in this post. It doesn't really make crysis a nice game, but atleast it runs and temps are really good.

First of all thank you all for your feedback. It's nice to be able to help.
I have some new bioses for you. All bioses have 2d clocks at 300/1125 and 2d voltage at 1,214V. Low power 3d and 3d modes have voltage at 1,33 and frequencies depend on the version you choose. UVD mode is clocked at 775/1125 and has 1,3v voltage.
Also there are two bios versions. One based on the 73 bios with the normal low noise fan settings and one based on the 71 bios with the aggressive fan control for lower temps. 71 is better for those that use the stock cooler. I recommend the newer 73 to those with aftermarket coolers or those who don't like fan noise.
I have named the bios files as "core-mem-bios version.bin". So "775-1125-71.bin" means you have 3d clocks of 775 core 1125 memory and its has more aggressive fan control (based on 71 bios). I recommend to rename the file you want to flash to something like "bios1.bin" as atiflash has problems with long file names.
As always test at your own risk and feedback is welcome.

Remember to reinstall drivers after changing bios. Overdrive tends to get confused and tries to load values from the old bios causing some games to crash. i have tested with UT3, COD4 and Lost Planet as well as Crysis and had no crashes with a clean driver install. I hope the new version works for you.

can't wait to try the .71 (830/1200)

THANK YOU!

edit: here ya go!

If anyone is interested in testing a 3850 bios please contact me via PM.

@ATi7500: I am glad you like it.

Did you get a chance look at my 73 bios I sent you with aggressive fan control?

If you mean this one: http://www.xtremesystems.org/forums/...0&postcount=73
Then sorry i did not test it. I will try it when i get a chance.

I did, but what do I know, might still be software bugging
gonna test 830/1200-71 tomorrow

[demowhc]

Hey guys Im getting the powerplay problem with 2900 crossfire...

where can i find a bios for 2900xt 512mb that sets all my 2d clock speeds, voltages and fan speeds the same as my 3d clock settings?

Yes that's a variation of the latest sapphire and it has great fan control, similar to your 71. Here it is in it's original form from Sapphire if you want it.

Daidalos... thanks again man.... good effort... i'm using the 73based 830c 1200m... brilliant...

Is that bios less aggressive than the 71 fanfix?

[De1337]

Is that bios less aggressive than the 71 fanfix?

According to the creator, yes

[ATi7500]

According to the creator, yes

it would be nice to know exactly the fan speed table of the bios you are speaking of

[Jeff Flowerday]

Is that bios less aggressive than the 71 fanfix?

Ever so slighty. My idle temps stay in the mid 50s, the fanfix 71 was keeping them at less the 50. Load temperature is just under 70.

[De1337]

Okay I ran 830/1200, but that caused crashes in Crysis (vista even said i had had a bluescreen after i booted up)

So im on 800/1150 now. Been playing crysis for hours, rock stable. Temps are also really good and i dont hear my fans anyway.

[purecain]

it seems that there are some 3870 cores which cannot run properly above 800mhz... mine are both referance HIS cards and seem fine in crysis at 830mhz core and 2200-2300mhz mem...
interesting....

I can't at all run 2300 mem... and core seems to max at 820Mhz.
Don't know if these powercolor just OC like crap or i got a bad one :O

[xMrBunglex]

i think the cores overclock fine. if i'm correct, the overclocking wall comes from the RAM getting hot with the stock cooling solution. the highest i can run my RAM at 100% game stable settings is 1176. i imagine aftermarket cooling would allow me to OC higher if i wanted.
