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

[Winterwind]

so, which bios is best for sapphire HD3870?

[Spyrus]

The one at techpower is ok try it.

so, which bios is best for sapphire HD3870?

I can't recommend any Bios just yet. It seem the one from TechpowerUP is supose to fix the a few things but since this doesn't work for me and I get the same results than i had before flashing the bios, i really don't know.

Its surely worth a shot to try though.

im using the bios in this thread (1st post) with my 2x HD3870 and works OK !

with stok bios if i set 865mhz the system freezes , when i flashed with the bios in this thread i tested 885mhz and no problem at all (didnt try more)

6400+ @ def, mem @ def (1066mhz/5-5-5-15)

flashed with bios from inq site.
904mhz gpu is fine for 3dmark03 but gives me vpu recover in 05.
the funny thing is that crysis timedemo gave me 11fps more compared to stock bios.. same clocks, it just is 11fps faster
flashed in win, didint uninstall or reinstall drivers..

I'm using BETA which is managing FAN speeds properly. It keeps temps at 60C for both cards and still is quiet . No problem with above 860MHz core as well .

where is beta bios???

the funny thing is that crysis timedemo gave me 11fps more compared to stock bios..

thats because maybe the INq bios is the one that set core clock to 875mhz Not the 777mhz default.....................

[Winterwind]

no, defaults are 777/1125 like normal bios

[mascaras]

yep , i see the inq site now , its the same bios in this thread (1s post) >> v010.071 (same bios i have)

can you post the link to download bios???

Same goes for HD3850 too...

HD3850 256MB (with board 102-B34003)

HD3850 PLL VCO Fixed Bios v010.071

Bios source updated from 10.67 to 10.71...
PLL divider algorithm updated (Engine clock limit fixed)...
Plus other irrelevant technical mambo jambo...

Use ATIFlash with force switch (atiflash -p -f X filename.ext) X = adapter number.

Have fun.

Aye aye

[Lightman]

can you post the link to download bios???

Yes!

[Spyrus]

Plz do not confuse the bioses.
They are all Ver 010.071

[Supreme(CDW)]

If i look around the only way to get the volts higher is with Hardmod or not?

My 3870's are running now 901/1276
But i want to push them higher someone got a idee?

[mascaras]

Yes!

I flashed the first HD3870 with that bios , reboot and black screen when enter windows

i had to switch card to second slot and boot with the other card in first slot , enter windows and flash back the other card with Bios in 2st post of this thread

dont want try again .........


thnks anyway

Sweet , Thanx Stilt.. think you could mod one with 770/975 clocks like denny posted but with the 71 source? the reason is catalyst now shows a max of 730 core? with denny's it allowed 900 in catalyst.

<3 x infinity!!!! thanx alot. only bad thing is my setup doenst want to cooperate.. at least the ram doesnt. oh wells. time to upgrade. all i can say is im WAYYYYYYYY more then happy with my 3850.. and again thanks stilt.. your the man

so my best 3d06 is 10,274
s939 x2 3800@ 3.05
3850 256 972mhz/999mhz
crucial ballistix 510mhz

edit: i cant submit for some reason jsut me or are the servers down?

[os008]

3850 256 972mhz/999mhz

How much voltage did it need please?

[STaRGaZeR]

So what is the 3870 BIOS that has the higher load vcore and is designed for reference cards? HIS one?

[JamesBong420]

How much voltage did it need please?

1.53v to get 972mhz.. i only got to mess with it for a little bit since i was trying to figure out why my mem is acting up. damn dfi cfx3200 always making me change my ram settings.. possessed i tell you

[os008]

Weird, was it stable 100&#37; at that voltage, i went up to 1.6v and couldn't pass 950, why didn't you go higher than 972?

Also, did you notice that there'sn't much performance difference between 760 and 860? i mean, i got only 100 points in 3DMark'06, and just 1 FPS in Crysis on high settings and 1280 res, it's so weird, as if i'm not overclocking in the first place!

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 )

well i can do 1000mhz core but i need 1.58 volts.. i couldn't get her stable no matter what at 1000mhz until i used my ducting trick to bring in cold air.

normal idle is 45c idle load 62c with ducting 19c load 35c


it would not do 1000mhz with no matter the volts when i had the normal air. but when i chilled the air it went like a mofo.

i have also noticed the little increase of score from 860-960 is about yes 100-200 marks on my weak s939 x2 3800.

but that was lunch so back to work. and more later.


edit: i dont know anything about cap mods. can anyone enlighten me please?
