Yes, your scores should be correct, because yours is a 64bit memory card, it would perform lower than the 128bit memory 9550.
As for the bios, i am not sure myself. haha.
As u can see i posted a question about it above....no reply yet though........

i was wondering, how much did you guys spend on your 9550's? I spent about exactly $100 on mine.. maximum overclock is around 525/337x2...

 

[ati.bob]

I spent about US$84 (after conversion) on my Sapphire Radeon 9550 card.. modded it into "near" 9600 Pro speed (except on the memory side).. 440MHz for the core, and 240x2MHz for the vRAM... all using stock cooling on the GPU (no cooling yet for the RAMs..)

[ReconCX]

... please read around and search before asking general questions like this..

as stated,

you can download omega drivers/softmod drivers

or use atitool and simple check the "unlock 9550" box in the settings....

Go and search around the forum.. there are plenty of explanation on modding 9550 cards..

I'll explain it again...

9550 cards comes with RV350 core NOT RV360 NOR R350/R360 core.. so don't flash it with a 9600XT BIOS which is for RV360 GPU only!!! An XT card usually comes with additional features like thermal probing, etc.. so flashing a 9550 card which doesn't comes with those feature might cause your card unusable..

9550 cards that are labeled XTs are not using RV360 cores.. they are labeled XT because they are usually pre-tweaked/overclocked to 9600 speeds or they are capable of 9600 speeds.. ATI does not officially release XT editions for the 9550...

 

[GoLLuM4444]

You may well be right but I think there was another thread where it became apparent that you can flash a 9550 to use a RV360 bios, just not the xt one as the temp. monitor etc. screws it up as you said. I'm pretty sure that you can flash 9550s to 9600 pros designed for RV360.

100 posts.

 

[ati.bob]

hmm.. you may be right.. a R9550 may possibly be flashed with a RV360 BIOS.. but it might cause problems later.. so better avoid it.. and one thing I should point out is that most 9550 cards when flashed with 9600 BIOS always seems to report they have RV360 cores.. although it's evident that all 9550 havr RV350 cores..

 

[gpenk]

thanks ati.bob about u explanation ,

sorri my english very2 bad

 

[Skandal]

Hi, i didn't buy my r9550 cuz i'm thinking wich is better, an Asus board that will cost me 81euros(about the same in dollars) with 128Mb 128bits of bus, or a Club3d 256Mb 128bits of bus that costs 90euros, both can be overclocked, but it think that the asus one will be more stable....... Say what you think......

hello there. great work on the flash tools, so i see.

Just to get things clear i'm asking for your help.

I just bought an Asus A9550 Gamers edition (which is an ati radeon 9550 128-bit) I don't know the exact chipset and bios info because i first have to install it into my computer

I want to flash this card to an 9600Pro and this thread is helping a lot BUT I would like to know 2 things:

1. Where do i get Atiflash?!
2. Which bios can i use best?!

Hope you can help me Oc'ing my 9550 into a beatiful 9600 Pro thnx in advance

 

[Clubvibe]

sorry for the dubbel post but editing won't work if your not registered (i'll be registered soon )
Do i need to use atiflash?! or are there some other flashtools?
And can i Overclock my '9600pro' after the flash (or am I to gready here )
And can i still install custom drivers like omega after this flash?!

just an general question about ati Oc'ing. Which ati tweak tool and drivers do you prefer?

Atitool i suppose for the tweaking (or is rivatuner better?!)
and do you use omega drivers? official drivers? or DNA-drivers?

PLEASE read the first post of this thread, you'll find all ur answers there!

PLEASE read the first post of this thread, you'll find all ur answers there!

i did read that post and I already know how to get atiflash (my mistake)
but not al my questions are answered? Are they?

I still want to know which bios i can use the best with my Asus card (the chip says 'samsung 434 TC40. is this samsung 4.0 or 5.0?)
And can i overclock it after the flash?

I'll read the first post again. more carefull this time

 

[ReconCX]

U'll just hafta figure out which BIOS works for your card. it's a guess and check game. Make sure to match up the mem with the BIOS.. chances are, you got 4.0ns but google it to be sure.

Newbie - first post.
Great site, ATITool and the bios download with clock change on the fly are superb. A per my signiature I managed to get take my Connect 3D 9550 from 250Mhz to 445.5Mhz (was stable until the 460's) and RAM from 200 to 222.75 (exactly half the core) giving 42% boost to 3DMark2003. CS:Soure Stress test now 63 FPS. The RAM gave artifacts going any higher (Samsung 5ns). I'm now flashed as 9600Pro using the Saphire 9600Pro 256Mb drivers with 4ns Samsung, with memory Mhz downclocked when I downloaded it. That was my 3rd attempt at using the 9600/Pro drivers, I tried the PowerColor 9600Pro, and the HIS 9600np, both caused by 3DMark to drop from 3058 to 2840-2860 with the same clock settings, wierd. My only guess was the memory timings were slower somehow on those bios (both were 398/203 5ns memory bios). Also my card would not take any 9550 bios execpt the one it came with, but it had no problems with the three 9600 bios. I tried the Sapphire 4ns bios to test my memory timing idea and it seemed to work, still stable, and my 3D mark went to 3082, better than with the original bios, and now o/c unlocked too. I've not tried taking off the heatsink yet - but would 460Mhz + indicate this is not RV350? It's a new card (Nov 04), model C3D6055. Anyway, thanks to all who put this site together and wrote the mod software.

 

[Clubvibe]

i'm sure it's an samsung 5.0. Omega drivers are telling me this by the bios facts wich are the same as a bios in techpowerup's bios database. The problem is... There are no 9600pro 128 mb with samsuung 5.0 bios available in the database. can i still flash it with an 4.0 bios?!

or is Tweaking the card with the omega dirvers (radlinker) or Ati-tool enough?!

 

[RobH]

The TC40 on your RAM chips means 4.0ns, (my card has TC50 - 5.0ns). Bye the way the first article says don't use ATIFlash on a 9550, it doesn't work (apparently), use FlashRom, it does work fine.

 

[Clubvibe]

so i noticed... i didn't read carefull enough.. well if i'm back in a couple of minutes it means the flash worked. wish me luck!
