ATI Radeon 9550 Overclocking and BIOS modding FAQ Guide

[curious]

can I unlock the BIOS of my ASL 9550 128bit 128 MB Radeon

I have ASL Ati Radeon 9550 128 bit 128 Ram but it has locked BIOS /I cant flash it/ Can you tell me whether it will be possibly to unlock the Bios so I can flash it to 9600 non pro. Tred both atiflash and flashrom without sucess- they say Cant write to rom 0FL01 Error /the BIOS is locked/. If possibly name program.

also, voltmodding can also be tweaked via BIOS, not specifically thru circuits and whatnot. I've yet to do that to mine yet but I imagine it will up the performance.. just, be sure to have good cooling first.

Could you be a bit more specific about that? Namely, how can I voltmod my Connect3D Radeon 9550 through BIOS, without doing any soldering on the PCB?

Hmmmm, on the ASUS website it says that the TUSL2-C is able to handle up to 4x AGP. Though CPU-Z tells me that it is running on 2x AGp, and only capable of running on 2x AGP. Does this mean i need a new/other motherboard, or can i unlock something? And does this come with the ATI Radeon 9550 or not?

mem timings

Hello everyone!

I have few questions about editing memory timings with RaBiT! I have Gigabyte Radeon 9550... It's overclocked with ATITool to 372/249...

These are my default mem timings:

Write Latency tWL = 1.0
CAS Latency tCL = 3
RAS to CAS Read Delay tRcdRD = 4
RAS to CAS Write Delay tRcdWR = 2
Row Precharge Time tRP = 4
RAS Latency tRAS= 8
Row Activate to Row Active Command Time tRRD = 3
Read to Write Turnaround Time tR2W = CL+3
Write Recovery Time tWR = 3
Write to Read Turnaround Time tW2R = 2
Write to Read Turnaround Time for Same Bank tW2Rsb = Use tWR Rule
Read to Read Turnaround Time tR2R = 2
Memory Refresh Rate MemRR = 24
Refresh Row Cycle Time tRFC = 14
Shift of RBS Signal for Read Data tRBS = CL+3.5
Shift of ERST Signal for Read Data tERST = CL-0.5
Shift of QSREQ Signal tQSREQ = CL-0.5
Shift of OE Signal for Write Data tDQM = WL-1
Shift of OE Signal for Write Data Strobe tDQS = WL-1

What should I change? Is it better to have higer or lower value?

Thanks in advance...

lower.. use ATITool to test it out first. if you get artifacts, put it back up..

Got a quick question, when using a 9600pro bios flash does the memory need to be the same? I am wondering because I have a sapphire 9550 256mb with 4ns Vdata memory. I can't find any other flashes with this memory.

Hi!
I have the same card with the same timings...
Have you tried the official BIOS update or our Gigabyte?
It didnt succed because it appears my card reference is low... maybe you can try yours, maybe it is the right reference!!
And then if you secced could you tell us the new timings? Thanks!

I couldn't flash it either! I've got message that my BIOS is allready the newest version... But it is not!!! I don't get it! What BIOS do you have? Are you using one of the 9600's BIOS? What is your GPU and memory clock? Mine is 372/242 MHz! That is maximum whitout getting artiffacts in ATITool...

 

[Inteleron]

Can u ppl post sum CS:S fram rates cuz all im buying it for is CS:S nothing else, so if this card can hold up well in cs:s ill buy it, i might also just buy a 9600XT cuz i can get 1 for 140$

Guys can u post some screen shots with ur net_graph frame rates of Counter-Strike Source plz, cuz im buying this card for CS:S i'd liek to know the performance b4 i buy it.

Some one tested Abit Ati Radeon 9550 Guru ? I have this card and I test it

DFS, what are your video RAM configuration /nanoseconds and memory brand/? If that result you have posted is real you beat them all /including non clocked 9600 pro/!!!!!!!!!!!!!!!
Also can you be more specific aboit standard and clocked GPU and memory MHz. Hope to hear from you soon.

Me again. I saw that you have the same motherboard like mine. When i clock mine over 161 mhz bus spead it refuses to start. I can only lift the cpu voltage by 75 mV. Also I have notised that with bus and ram freq lifted it gives me less 3d mark points than with nominal FSB /133MHz/ but twicked ram 2,5-2-2-5 Bank interleave 4. Is it the same with you?

Now i know why my results are so shitty! My Mobo can only handle 2x agp! Shit, i definetly need new parts! hmm i put down my memory timings for my memory from ?7-9? to 5-7?, anyone know what this means? ( timings from my memory, so not the vidcard memory )

Edit: my card ( ASUS radeon 9550GE/TD ) has rv350 chip, right? When i run everest it comes up with that i have rv360 chip, and have an 9600xt? ( yes, i flashed bios and it should b 9600pro with rv350 ) Hmm, awright: funny!

Edit: Hmm, that bios was set for 398/203x2, while the real speeds should if it really was xt bios: 600/500x2.

Edit: Not my memory timings but chip timings? Everest still showed them as 7-9 instead of 5-7?

9600XT's run at 500/300x2...

wooops, my fault! but still. dont u think its weird?

 

[Inteleron]

Isnt the Asus 9550TD 64-bit also?

 

[Rule-R]

I dont have the td, ive got GE/td. that one is 128bit

 

[denise]

5/7 or 7/9 show you SDRAM cycle time TRAS/TRC(you system memory) and unrelate with video card mem timings
i dont know why Everest still showed them as 7-9 instead of 5-7
SDRAM TRAS Timing mean:
The minimum bank active time.
SDRAM TRC mean:
Bank cycle timing, or the minimum cycles between consecutive activations of the same bank.
The shorter the better for performance, at the possible expense of stability.
i have got a intel815 chipset mobo,too-and that support AGP4X(AGP ver 2) and you can use everest to get information about it(in motherboard/chipset)
any way,about manli 9550,who have it?is this a good card?

 

[Inteleron]

Yah i got one of those cheap Intel D845PEBT2 mobos with 4x AGP Im still running my Radeon 9100 128mb 250/200 @ 300/520 DDR, I get 45-65 Frames per second in Counter-Strike Source, I can immagine what a 450/520 DDR 9550 can do, proby 100 frames.
