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

[sdumper]

I know im late to the game posting but Im looking for a bios that adjust the GPU voltage for me. Ive tried the pencil mods and they dont seem to really help.

Both my cards have the revised bios for the divider issue but im capping out at 22700 on 3dmark06 and going from 864/1350 to 877/1350 doesnt improve my scores at all...

There is no "GPU voltage modified bios" working to date, AFAIK.

Thanks...

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.

no flash either? damn nice core.

yup no flash... everything out of the box.

[malik22]

Your welcome!

My cards are reference Sapphire and this BIOS is SuperB for them...Might be that our boards aren't identical

I've flashed from DOS using
Atiflash -p 0 name -f
where -f was important addition to this procedure

I don't need to open RT just to adjust FAN speeds anymore On the other hand IAX BIOS allowed me to clock cards up to 1500MHz from OD (but I couldn't reach it stable )

I aslo have a pair of Sapphire to what fanspeed does the bios you posted Sapphire_HD3870_fixfan_unlock.bin set the fans? and you recomend that bios for my cards or theone posted on TPU?and do those two bioses unlock the 885 cap in CCC.

sorry for being annoying, but i wanted to quote this one because i'm also interested in a BIOS with a more aggressive fan profile. anything you can tell us about it would be appreciated.

HI all just received my 3x3870 powercolor zerotherms... stock clock 800/1200

well none of them wotking properly... 2x working at 800gpu and 1170 mhz mem... should be 1200mhz, 3 one is just epic fail which fails miserably at 800/1126mhz... random instability etc ... + there are now screws for mem cooling plate... other two has them... IM so mad atm... paying for speed... getting what?

I used the bios lightman posted Sapphire_HD3870_fixfan_unlock.bin on my two
Sapphire 3870 and it fixed the 862 GPU Clock Limit but also fixed the fanspeed its no longer at 25percent on both cards now it varies beetween 40-50percent on both cards keeping them in the upper fourties.Hope that helps and I was also wondering does the www.iax-tech.com bioses also have different fanspeed then the original?

that BIOS rocks. thank you Lightman and thank you Malik. it's quiet and keeps my GPU's under 60° full load. perfect. for those who want it and don't want to search for it, it's here:

Link doesn't work

probably because i'm an idiot. i edited it and the link is good now. sorry about that.

I have finally my Sapphire HD3870
I flashed the bios posted in the first post into the card. the clock limit is indeed gone but overclocing this card is strange.

I use rivartuner to oc the card when I select 891 core it will set it on 891 core if I set it to 900 core the clock stays 891 if i set 903 core same problem when i choose 907 core it will set 904 core but my card can not do that stable is there a way that that gap can be fixed. these gaps are not only on that clock but the whole range. is that a known problem????

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.

Thanx.

That sucks big time, is that only for this series or is it also other ati cards? if so I think that I might step back to the green side :P

all 2900 and 38xx cards do this, as do all nvidia 8800 cards. no big deal really

I see this image of the card killer laying and pawing at the dead card in a uncaring manner

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)

my xaserIII had a system like that but also has the holes for fasteners
my last pet was a runt atiel,Honky,he could do hi honky and the charge whistle and the wolf whistle,and many times over and over when on a roll,we were buddies for about 21 years all told
try to keep the crew out of trouble

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.

are those bioses fixed like the one in the 1st post ?

[PhilDoc]

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