Unleash the Gladiator (RV670): 862MHz GPU Clock Limit Fixed

[malik22]

Yes they are. Have tried all of them and now using the 875/1250.

PhilDoc what fanspeed do those bios have? and are you on vista?

[rintamarotta]

Yeah, I had just put everything in my new case (Tt mozart) and was pretty happy with how everything turned out. Plugged everything in and fired up the computer. On the Mozart the PCI brackets are held in place by some plastic clips (retarded idea!). Well, not even five minutes had gone when the computer suddenly rebooted and everything went black. Looking down I see my 5 month old kitten standing on her hind legs pushing towards the PCI brackets and the one above the gfx card was missing. It fell down on my Hd 3870 and shorted it out! If the brackets had been tightened down by screws my cat could never have been able to push it out of place. Not much to do but send it back and put in one of my old cheap ass GeForce 7300 or whatever. Its the cat in my avatar btw (I have four)

You got nice cat, hope it wont destroy everything

Yes, I'm using Vista. Haven't really looked at the fan speed. I cooling with a V2 with the fan connected to the mb.

Do you have two in crossfire?I was asking about vista to know if you had any problem with crysis.

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.

Some wierd things are happening, GPU-Z can't identify Crossfire being enabled, and I am not able to clock the 2nd card with Rivatuner when in Crossfire mode.

3dMark06 scores are similar to the stock bios, at around 18,500, with Crossfire. Has anyone else had problems seeing their crossfire in GPU-Z, and/or being able to clock the 2nd card with Rivatuner?

I suppose I've been successful, enabling higher clocks - but I can't see any real-world benefits yet.

WTB voltmod?

[superbowtie]

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...

Have you performed the pencil mod? It helped me a good deal on my HIS cards.

[zbogorgon]

Yes they are. Have tried all of them and now using the 875/1250.

I am unable to flash bios to my card. is there some kind of trick or sth ?

[10e]

How are you trying to flash them?

If WinFlash doesn't work, you may have to use ATIFlash from a DOS/Win98 command prompt boot disk.

I found with the 875/1250 BIOS I had major problems with WinFlash, where it would ramp up CPU to 100% and never actually start/read the cards.

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.

There is a mean bouncer standing outside of your favorite bar (863MHz).
Bouncer´s name: is PLL VCO Divider

HD 3870 PLL VCO Fixed Bios v010.071

Forgive my ignorance, but I downloaded this bios and when I unzipped it, it has no extension (.rom or .bin), do I just flash it is it is?

atiflash -f -p 0 S3B33904.103

Thanks.

[xMrBunglex]

are you sure you don't just have Windows set to hide file extensions? i'm sure the file has an extension.

[necron66]

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

ive tried many of the bios' ive found in this thread, and i havent found one that is version .071 and will let ATI CCC go over 860. (i have Sapphire 3850 256mb) I can hit 930 in Rivatuner usuing the .071 verison(CCC is limited to 730) but i would really like to have the low power 2d and 3d settings that CCC gives. I might just not be usuing riva right, but i was wondering if there was a .071 unlocked bios that would work with ATI CCC floating out there somewhere.

[rob[GL]]

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.

[rob[GL]]

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?

[d4d4cH]

does a bios with fixed bug exist also for 3870x2 cards, cause i need one for mine

[nicepun]

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.

[CrimInalA]

hi ,
i will rephrase :
850 is my max stable oc with 1.25v on the core .
anything above will give me lots of vpu recovery errors , thus is not stable . or at least the ati driver doesnt think its stable and wants to recover something .


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

I have the same problem with a 2400XT.

Can someone help me modding the bios to remove the limitation?

Thanks.
