I don't know of its faster but i did that hex mod
on a 875/1200 bios downloaded somewhere
Different people are running it now !
like Extera's cards are running fine :)
And hits the 25000k in 3dmark06 with a Yorkie
Ok.. i am going to give mine a flash w/ the bios. I'm using Denny's and got 890/1300.Quote:

No need for hex mod!
You can edit the bios clockspeeds with this:

Ive never been able to get that 3870 BIOS editor to generate a valid BIOS....atiflash and winflash both report invalid VBIOS :shrug:
Hmm..bios editor worked fine for me. I flashed both my cards to 890/1290 just fine. The problem was teh card performed well in single.. but in CF I had to drop the speed. Trying to find the max speed right now.
When you guys OC your CF.. how do you adjust the speeds on both cards? Is there one place where you can adjust both cards at the same time, or do you have to adjust each card separately, like the fan rates?
Ton
you have to adjust clocks for each card (CCC or Rivatuner)

Mascaras,
Thanks for the screenies :) I will give it a shot tonight. I think i was benching asymetric last night. that would explain some of the "Weirdness" I was encountering :)
Once I get the max CF Speeds in place, I can try to do the vMods next :D
Ton
another thing , To crossfire work properly the Catalyst A.I must be in STANDARD Mode and CF Enable in CCC

Thanks mascaras...... after I got home from work I was thinking about it and tried to the drop down....... :D
anyone already tryed Auto-Tune in CCC ??
my card was already at 950Mhz then i decided stop going any further
940Mhz
http://aycu16.webshots.com/image/395...1213577_rs.jpg
950Mhz
http://aycu27.webshots.com/image/399...7255943_rs.jpg
i think Auto-Tune not working OK and its very dangerous , mainly for memory ..........

Does AI have to be in standard mode or just enabled?
standard or disabled.
Crossfire doesn't work well with advanced AI enabled? I tried two HD 3850s under Vista x64 @ 730|1000 with Overdrive and they did 16.5K.
http://service.futuremark.com/compare?3dm06=4420651
The "unkown mobo" is a BX2 :p: Guess I will go back and try standard.
They recommend that AI is either disabled or in standard mode.Quote:

I ran it again and it was higher

16761 vs 16557 for the first.
Btw, do overclocking in Crossfire with Vista 64bit work well now?
Thanks guys, that cleared things up.
@Blacklash, was that run in standard mode or disabled for AI. Disabling the AI should give you the highest score.
Might be me that have some strange issues here... I have two 3850 256mb and running CF. I can only clock one card with rivatuner with this BIOS. Also, I can not clock any card with CCC.Quote:

mascaras: auto-tune does not work correctly, at least it didn't for me. It put my core about 50Mhz beyond my tested stability which instantly caused my system to lock up and reboot.
As long as you disable driver check via f8 during post you can overclock a single card with Rivatuner. If you are using Overdrive from the CCC you need not do that and you are limited to manually setting 730 on the core with the HD 3850. You can get both cards to OC though. The bench I posted earlier was 730|1000 for both cards done from the CCC.Quote:

I am hoping W1zzard @ techPowerUp! releases a version of ATi Tool that allows me to get my second card well. I'd love to have access to boost the voltage too.
Really? First one was advanced cat AI and second was standard. I thought disabling AI turned off Crossfire? I'll be happy to try it though.Quote:

Is there any chance you could extract the BIOS from your Turbo III OC'ed version and make it available to us?

The bios version is 010.073 and CCC lets me go to 885/1200 maximum (I tried the oc beyond this limit using rivatuner).
Any suggestion? :>
sry for OT but i got the the same problem with Asus HD2400pro 256mb, maybe some1 can mod the bios to get over 860 core?

Maybe the BIOS determines what speeds are available in the CCC??
As for you being unable to go over 891Mhz core speed, try manually raising the fan speed in Rivatuner to keep the temps down. If that doesn't help then the GPU needs more voltage so the only option is a voltmod.

do any of these BIOSes have a more aggressive fanspeed profile? i'm using stock cooling on my 3870's and want a new BIOS that forces 60% fanspeed, either when i start 3D clocks or at a certain temperature threshold. RivaTuner isn't so hot with CrossFire - i have to manually force fanspeed up and down before and after running 3D apps. i'd like fanspeed to be more aggressive when in 3D mode without having to run a third party app.
I just replaced my 8800GTS with a HD3870 and wanted to c how good it overclocks.
I installed rivatuner 2.06 but when I click on customize to overclock I don't have anything except for low level refresh settings, desktop schemes and diagnostic , I have the lastest CAT 7.12 installed.
Is anyone having similar problems? (I tried reinstalling both the driver and RT)
i need a more accurate OC tool hehe
thanks a million in advance :)
well ,here is my new baby in action (with no vmods or pencil) and only CCC...
room temp is 18c
Sapphire HD3870 + Thermalright HR-03 GT

at 931/1300MHz
http://img161.imageshack.us/img161/7...6935mhzwi6.jpg
great temp with the HR-03. that's awesome. i still can't get RivaTuner to work with both my cards with an automatic fan profile. if there aren't any pre-made BIOSes with better fanspeed control, is there a BIOS editor out there so a nub like myself can try to mess with it? i'll probably sell my cards when the next gen comes out, so i really don't feel like spending $100 on aftermarket cooling for them. i just want a BIOS that forces 60% fanspeed when the GPU starts to warm up.
no flash either? damn nice core.Quote:

Got my new card today after my cat(!) killed the one before this.
I flashed it with the iax-tech 860/1200 BIOS. I ran 3Dmark at 891/1341 but the second time I tried it everything locked up, Ill try it later tomorrow. Pretty good for such a cheap card:) Maybe Ill try a volt mod but its pretty good as it is for now. This is my first post here, thank you all for a great forum!
Interesting...
I appear to have degrading performance on this beast. After the intial flash I was benching at 877/1350 - 1360 fine but after a few days of rigorous benching it is now struggling for stability at 864/1350. It will run 864/1350 just fine in 3dmark06 but locks up in 3dmark05 and sometimes in AM3...
Sorry got the lack of post, busy with school.
I dunno if u can use this bios on reference cards as the board might not be reference. I know the rams are hynix 0.8ns ones from another forum.
yup no flash... everything out of the box.Quote:

for the mem i din't tested further than 1300. I am happy whit this card his clocks but the fan speed is set at 100% and its loud!
So I need some after market cooling for this one.
This is the way the core clock is calculated, you have to live with it.Quote:

Color me confused or maybe I am just an idiot.
I flashed the bios from the first post and Overdrive is still limited to 885, is there a secret handshake.
I have read page after page of this thread and that "should" be all that is necessary?
Thats normal if you want no limit on CCC use one of these.Quote:

Hi there,
I'm a new owner of a nice rig, my bf and I built it and I'm trying to crank out as much from it as possible. He thinks I'm crazy.
I have 2xEAH3870 cards, and have flashed them using the winflash as described in this thread. Initially I thought I had made a horrible mistake, as I couldn't detect crossfire anymore, but with the reinstallation of the 8.1 drivers and hotfix I got crossfire working again.
Right now I'm worried that I may cook my cards, since ASUS Smartdoctor has stopped working (I assume it can't talk to the new bios on the cards).
Should I just use RIVA tuner? It seems that I have to specify fan controls in RIVA per card.
What about the overclocking? Do I have to clock up each card individually? Or is there a way to do it together (the CCC panel doesn't show any clock speeds above 885).
I've found this thread very informative, although I do worry I might fuxxor my system with all the tweaking options you guys present.
Cheers!
Your cards may have come with a bios revision new enough from the start that they did not require flashing.
You should always check that first.
The stock bios wasn't able to clock past the 862 limit, and I have successfully flashed and can clock up to 885 now.Quote:

I suppose I've been successful, enabling higher clocks - but I can't see any real-world benefits yet.
WTB voltmod?
kinda bummed out about my OC 841/1241 CF sapphires, seems to be about all i can go before it goes unstable after flashing bios to the fixed fan version. Before I could have sworn it would do 850 on the core with stock bios. I've tried various bios and no improvement could it be where i'm flashing from windows? and to boot last two nights the room temp has been 49*F with two 120mm fans blowing on my cards in a stacker 830.
and ATItool doesn't run for me does anyone else having this problem. it will show in the tray but acts like it freezes when i try to use it. Its getting rather old having 3dmark crash or COD4 crash and having to fix my resolution and clocks.
Use control centre to clock both cards, youll need to select and set clocks for each of them. 18.5 in 06 sounds ok for stock crossfire and a quad at about 3600mhz...Quote:

For those using CCC to clock a dual-card set up you actually HAVE to enable Crossfire to select each card in ATI Overdrive, otherwise only one card is available.

It's set to show extensions, it just shows as S3B33904.103, and wont open it the bios editor either.Quote:

Edit: Supid CCC. 2d clocks stable at 950, 3d clocks only stable at 860, same problem as everyone else. Not willing to flash new card for miniscule gains... Back to working on CPU clocks.
I may have a change of heart... I am finding that 875/1250 (set in CCC) is stable to play games, but sometimes small artifacts appear. That is not acceptable to me. Will bios flash improve voltage at all? Or does bios flash just fix stock clocks?
does a bios with fixed bug exist also for 3870x2 cards, cause i need one for mine :)
So I got in on the BB VisionTek $129.99 deal and of course I wanted to tinker with the card. I used the bios found here used RBE to modify the fan speed using the original bios as the values keep the card real cool then used atiwinflash as follows: c:\fullpath\atiwinflash -f -p 0 c:\fullpath\bio.bin to force flash and the card is working fine. Before 840/1170 was the max values for overdrive, now...well have a look for yourselves.
P.S. I've included the bios with the modded fan speeds. AND OF COURSE, USE AT YOUR OWN RISK. I'M NOT RESPONSIBLE FOR ANY DAMAGES.
Hi all ,i am reading about this special bios to get past 862 clockspeed .
i am running a xpertvision Radeon 3870 card , with bios version 010.081.001.000.000000
my fan speeds are all fine atm . but i am hitting a wall at around 850 (could as well be 862)
my memory craps out at 1050mhz already , no cooling on them . (AND i just find out it is DDR3 , and not DDR4)
the core has a non standard cooler on it , which seems to keep the core quite cool even when running at 1.30v
the special bios seems way older than mine . Thus I am asking myself (actually i am asking you guys) : Is it smart to upgrade my current bios with this older version ?
thanks a bunch
As you have not tested if your card can pass 862mhz, no.Quote:

Then do i need to flash with .71 ? and when i do , will my fan go bananas ? are there modded bioses for my card (which has DDR3) ?
cause i am running a much newer build atm .81
that's the card
