I HAVE MADE AN ODD DISCOVERY ABOUT SOME 9550 cores that could possibly help!

[sweeper]

No go with the Sapphire Bios. Gave me errors, artifacts, etc. Flashed back to the GeCube 9600 Pro Bios. I haven't tried the Powercolor 9600 Pro 398/200 bios yet. But I doubt it would be any better than the GeCube's. I can run 400/270 at best. Oh well...

It was not mentioned in my earlier post, but I should also say that each move of the horizontal resistors also toggles REV_ID between 00 and 80. Of the two vertical resistors, only the upper resistor seems to be able to toggle Revision ID.
To convert 9550 to 9600 Pro, two resistors would need to be relocated as well as a BIOS flash to prevent the card from being read as 9550 or 9600 SE.
Of course if overclock results are already optimal with BIOS flash alone, this information is.... Well... Just informational.

anyone around here stripped down naked a gecube 9550XT card? the default for this card is 400/250 and is natively recognize as 9600XT by windows... i wonder what gecube did to these cards? and ive heard, the later revision even clocked higher (432/277)... it's like buying a factory OC'ed card...

Oh man... anyone got detailed step-by step instructions to convert a "vanilla" 9550 into a 9600 Pro?

 

[Dadoremix]

anyone have bios from ati 9600 pro or XT with hynix 4.0 ns 128 ddr ram?

i have testet with ati gigabyte 9550 to chanche bios to 9600 pro or xt .. from ATI BIOS Collection with no name ram .. .. none of working always dark screen

 

[sweeper]

Are you saying you flashed your Gigabyte 9550 or tried to and get no screen after the flash? Do you have the 128MB, 128-bit or 128MB, 64-bit version?

I have only found 2 Bios's that will work with the Gigabyte 128MB, 128-bit card:

GeCube 9600 Pro 128 MB Feb 3rd 2004 2:05 PM Apr 18th 2004 5:25 PM 398 / 203,Hynix 5.0

Sapphire 9600 Pro 128 MB Aug 13th 2004 6:11 PM Oct 21st 2004 11:08 AM 400 / 230,Samsung 4.0

 

[Dadoremix]

yes.. i try flash to another brand : ati,spahire, gecube...

it working only with ati 9550 bios 128 ddr 128 bit . and
ati 9600 256ddr 128 bit .. wit no long

my card is gigabyte 9550 128 ddr 128 bit memory ..
and for now its working on orginal bios with 250/200 stock and OC 400/260*2

please give me direct links to bios .. i would try this 2

and yes.. i flash with
flashrom 2.40

flashrom -s -f 0 bios.bin

that command .. the good one is that i have old PCI graphic card and i save my new gigabyte 9550



edit..

for bios you type ..
gecube

Sapphire 9600 Pro 128 MB Aug 13th 2004 6:11 PM Oct 21st 2004 11:08 AM 400 / 230,Samsung 4.0

Both are located on the BIOS download page.

Flashrom -p -sst 0 "BIOS.bin" -f

[Dadoremix]

and witch bios is better?? spahire or gecube??
what is now on your car .. and how high you OC?

I go to test this bios on my card

 

[sweeper]

using the GeCube 398/250 BIOS now.

i just got a 9550 abit, that one came with 3.6ns rams, i was able to get the ram to 250 (i didn't wanna push it) and my GPU is at 440 (didn't wanna push it either without better cooling. i scored 3200 on 3D mark 03. Any ideas on how to upgrade the cooling? the card came with a crappy 40mm fan that i can probably swat my hand and produce more wind than it can.

 

[sweeper]

I'm using a Zalman ZM80-C HP with the optional ZM-OP1 Fan and BGA MOSFET passive heat dissipater's on my RAM. The heatsinks on the ram didn't really do much for it's overclock ability but I thought I would throw them on there to help keep the ram cool, though the fan does the job just fine.

 

[warlock110]

man that's too expensive i got this card brand new for 65, so i'm not spending more than 20 bucks on cooling . i was thinking of the iceberg, and since it comes with 4 ramsink, all i got to do is chop 4 more, and use their thermal tape dam i got midterm tomorrow, or else i'm hitting up on fry.

i think i got a RV350 core, how high does this one hit? i put it on 450 and it blacked out on me during 3Dmark, ATITool said the max was 460, need new cooling? the ram is rated at 3.6ns, so they are good till 275, maybe i can edge out and push it to 285.

 

[sweeper]

Well it scores 3500+ in 3Dmark 2k3, so I'm happy. Plus I traded some other pc stuff for the Zalman so it didn't really cost me much. Got the BGA Ramsinks of the net too. Got a set of 8 for .75 each.

 

[warlock110]

oh crap, my card's mem get so much artifact @ 275 that it blacked out after a min. and if i set it to 430/250 i'm getting blacked out after 1 hour of artifact search, i think my cooling isn't good enough.

the stock cooling used a thick pad that was much thicker than my layer of TIM, (the stock cooling also had a "CPU trim" attached to the heatsink, i'm still using the CPU trim so i don't think that my TIM is touching the core properly.

 

[sweeper]

Get a better cooling system for that card!!!!!!

[warlock110]

i'll go check out my local fry and see what they got, ram sink is a must, but i don't kow if i can afford ZM80
