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

[cstkl1]

i would take a look at Gigabyte GA-MA790FX-DQ6 AMD 790FX (Socket AM2) PCI-Express DDR2 Motherboard http://www.overclockers.co.uk/showpr...d=5&subcat=808 yeah it might be a bit on the pricy side but , 2x16 and 2x8 for cfx , the asus M2R32-MVP has 2x16 and the msi also has 2x16 , as far as the info i am seeing about those cards. ( hope that helped )

dont dude
a friend of mine has both of the mobos from msi and gigabyte
he is having problem of overclocking the rams even to 840mhz

and for 3870 quadfire u need 8.46 drivers

[mattmartineau88]

does that equate to 16x16 operation with two cards in crossfire on the board? the gigabyte one is for singl slots unfortunately and if i was gonna spend that much i'd probably just go to 775

go with MSI K9A2 790X. this is PCIe gen.2 where 8x means 16x on older M2R32 580X based mobo.

Regarding gigabyte not running ram over 840MHz look at my sig....

Ahhh brill cheers mate and nice one wit the ram

nice just noticed
well that friend of mine just gave up
selling his 2 pairs of 3870 dirt cheap prices
and selling of that mobo of urs for RM799/3.4=235
seeing that he changes hardware like me having haircut twice a month...
well

Guys it appears that the bios file is .103 file extension.

Notice that most ATI bios is either .bin or .rom is there a diff?

So i just make my thumbdrive bootable and put ATI Flash along with the bios on the first page and flash it in dos?

Cheers
Jeremy

About that volt mod.
Has anyone noticed that in the HD3870 BIOS (like in the HD2900 BIOS) at 0ADC0h you can find the 10 power state preset with core, memory and voltage values?
Core is set to 777(3D), 700(3D?) and 300 MHz (2D).
Memory is 1126 MHz.
Voltage is 1.327 (3D) and 1.241 (2D) volts.

Lets see some voltage changes and results!

[Sage]

praying someone works how to soft mod the volts

id rather not get out the soldering iron just yet

im running a powercolor @ 865 and 2600.

We should aim to make it 1.4 vCore IMO. 55nm chip with the dual slot cooler should handle that no probs

yes..available since few weeks back..but very very limited stock
when u are coming to kl

[tiger8312]

Just curious where you've found the BIOS?
You said the BIOS was fixed by AMD Graphics department and I can't seem to locate the BIOS from the official website...
I would appreciate if you give a link to the official support site.

[Spuggi]

[pitya]

You should get 1.377 Vcore with this BIOS image.
(I don't have a 3870, so i cant verify)
Is someone brave enough to try out?
Use at your own risk.
(Oh and of course the checksum is no longer valid.)

dude for some reason lately

with a few brands
we seem to be getting stuff like way earlier than the rest of the world
the 8800gt was available 10 days before the launch
the hd3870 was 5 days before the launch

yup mainly in lowyat but usually i deal direct with distro

the shortages for 8800gt has been picked up by zotac and galaxy cards
most of the guys here reported by flashing the galaxy cards to the SSC bios they manage to get higher clocks.

oh yeah the shops are running some political thingy
a lot of them have it but its reserved for their frequent customers.
and some distro has been harrasing a few shops
two incident came to mind
buildtech the distro for asus gpu/mobo threaten a few shops a month ago that those who do not take the 2900pro stocks from them.. they will not get the first preference
kaira the distro for XFX now is saying if u want the 8800gt ADE u need to take 10 8500gt...

uik thought u would be busy with the overclocking competition in indonesia

how did team koc do??
heard u guys had bad luck on hardware
and a few others
and some of them did a combo country team..

Yo man which BIOS editing tool did you use to make the mod? ve~~ry curious

[Sampsa]

Hmm strange, I'm running Gigabyte X38T-DQ6 and Radeon HD 3870 and GPU-Z reports: PCI-E 2.0 x16 @ x8 2.0, I wonder why?

[dinos22]

hey guys

does the 3850 card have a clock limit and is there a bios to use on those

got a bench session on sunday
might as well try to take advantege of that since we'll have acetone dry ice water loop in Xfire and all

what application will let users adjust volts for these ati cards

Switched to Radeon HD 3850 and GPU-Z reported PCI-E 2.0 x16 @ x16 2.0, then changed back to Radeon HD 3870 and it also seems to be working PCI-E 2.0 x16 @ x16 2.0, strange

Well a simple Hex editor will do it if you know where to modify.
AFAIK there is no automated tool available for hd3000 series yet.
This is why no checksum recalculation.
The hex edit method worked well for HD2900 volt and clock mod.
You can find info about it somewhere here.

wah... u got many contact out there ha... lucky u...
i only know retail shop.. distro are beyond my reach...

835/1321 MHz seems to be the limit for my Radeon HD 3870 sample from AMD (Non-qualification sample).
