maxing out the 9550

Maxing out the 9550/9600 series

I got an Iceberq (original, copper 5000 RPM). Im stable at 420 core now(dropped down from 425 ATITool limit)
My Iceberq is motherboard chipset and vga kit, so now i have a nice little copper southbridge heatsink
P.S. The Iceberq 4 does not fit on the Powercolor 9550 256 MB

Memory is now at 215x2 mhz which is 100% stable (dropped down from 225x2 ATITool limit)
Memory manufacturer is "Mira" if anyone knows of them contact me immediately!
Memory is 3ns but will only do 215x2 mhz

Im going to get these copper ramsinks: http://www.newegg.com/app/ViewProductDesc.asp?description=35-116-012&depa=0

Which card manufacturer is yours? For my results, I got my Sapphire 9550 card to a stable level of 440.10 MHz for GPU and 229.50 x 2 MHz for the RAM by using the stock fansink on the CPU and no heatsink on the VRAM..

connect3d with stock goes 450/240 100% stable with hynix 5ns ram.

I havn't tried that speeds with the 9550 original BIOS though, I think it will give better overclocking.. As I'm now using Radeon 9600 BIOS, I think the memory timings in 9600 are a little more agressive than 9550 (I think..), I can still push the card at a little bit higher, (I tried it brfore at ~240 MHz RAM) but I prefer to keep the card longer..

BTW: Sapphire 9550 uses Samsung 5ns RAM chips.. What a waste for the overclocking side.. 5ns!!, compared to some 9600 uses 3.3, even 2.8ns chips

The best i saw for 9600np was 4 NS. I never saw 3.3,2.8 ns.
Best i saw for 9550 was gigabyte with 4 NS

 

[ati.bob]

4ns? Not really flashy, but can really improve chances of overclocking.. I did remember to see 9600 series card sporting 3.3ns RAMs.. Although I forgor who was it from though..

 

[[-Yoshi-]]

I have a ASUS Radeon 9550GE/TD with the original Bios and it has 5ns Samsung memory and it runs 100% stable with stock cooling at 440/250, ATITool says top is 462/252. I will fit it with some extra ram heatsinks and better GPU Cooler to try to go higher.

 

[amd]

I have a Gecube 9550 extreme edition with hynix 2.5 memory chips. I've flashed the vcard bios with a vcore running @ 475 Mhz, and memory running@ 320mhz x 2 (640 mhz). this is the default speed right now with no problems whatsoever.

 

[wazzledoozle]

Powercolor 9550 has MIRA 3 ns memory.... But can only do 215x2 mhz

Doesn't Vcore means Vontage Core?? (Hence the "V"?) I think you mean core speed..

Hey Wazzeledoozle, I think I found the manufacturer of MIRA memory chips.. It's made by Arestech Electronic Corp. Taiwan .. [Click here for URL]

I found it while I Google it at Tyan M/B's website where they list their recommended memory modules [Click here for URL]

*EDIT*
Oops.. I think that's one of the company that uses MIRA chips.. sorry...

Any clues are very welcome thankyou very much!

Powercolor 9550 has MIRA 4 ns memory....

MIRA 4 NS???

4 ns means 250 MHZ at default. So u should be able to OC it up to 270 without HS.
215 is sloooow.

I actually have 3 ns cas timings, i got RaBiT and checked, but that means i should be able to do 300 mhz right? Are there any other factors which could hinder performance? When i try to change the CAS timings, even to slower timings, i get lines thorugh my screen

 

[amd]

here's my benchmark result for 3d mark 03. I've flashed it with a sapphire 9600 pro fireblade bios and clocked it at 500mhz core speed, 325 (650 mhz) mem speed using radeditor. No problem whatsoever. Still using the stock fan and attached 2 mem sinks at the back of the card....My only drawback is I only have a 256 mb ram


3dmark 03

3dmark 05

 

[wazzledoozle]

Thats a great 3dmark 03 score for a 9600, check if it has the RV360 core, and if it does try your hand at flashing it to 9600XT

 

[amd]

Yes, it has an RV360 core. I Tried flashing it with several types of 9600 xt bioses but i have no luck with it. Forcing to flash this card with XT would give me black screen. Good thing i have a spare pci card to bring back the original bios. If there is only a member here who could modify a bios xt for this type of card will be gladly appreciated. =D

 

[ati.bob]

Isn't this supposed to be a "9550" section? Discussion of other models should be taken to another thread.. (mods might call this thread hijacking.. )

And amd, how do you get your card to run at 500MHz core and 325Mhz RAM?!?!? is the card a 9600 or is it a 9550??!?

 

[amd]

it is a gecube 9550 extreme edition with hynix memory rated at 2.5 nanoseconds. I have successfully flashed the bios with a saphire 9600 pro fireblade bios. other 9600 xt bioses that i tried would result to a black out screen.

 

[wazzledoozle]

No one knows why my 3 ns CAS timings ram on my 9550 cant do more than 215 mhz? Any other imporant timings?

 

[ati.bob]

Maybe that's because it's the limits of those chips.. Maybe you should put some TSOP RAMsinks on it.. maybe overheating..

 

[wazzledoozle]

Oh geeze, I burnt my hand when i touched a DDR chip while playing doom 3 for 2 hours. Ouch!

TSOP sinks coming soon!

 

[amd]

The same thing happpened when I was playing far cry for three hours. I think DX9 games really makes the DX9 cards too hot.

 

[ati.bob]

I'm also thinking of getting some copper TSOP RAMsinks from Cooler Master.. looks quite nice.. Maybe can give my mem a little more overclocking..

 

[Fahim]

SAPPHIRE 9550 256MB has Mezza 5ns memory which is overclockable to only 215 (430)MHz from stock 400. This card is a crap.
