I chose to end the auction early on ebay cause they jacked up their prices again and i would be losing money.
 
hello....i'm still a newbie and want to find some experience to oclock my Asus A9550 GE.....it got Samsung 5.0 ns on it.....previously I ovclock it using ATitool with the stock fan,and manage to get core:486/mem:256 and try benchmark it....the results: 3dMark03@1024x758:3414 and 3dMark01@1024x768:115++ .....any comment???.....by the way...i got myself now an arctic cooling rev3....maybe looking forward to ovclock it even further....i dont dare too flash the bios....cos i'm afraid it would turn out bad....still a newbie as i said....anyone knows how to change the memory timing and what's the optimum timing?....is there any temperature monitoring software for this card???....thanks....
 
use ATItool do memory timing. read the first page of this thread.
 
Sry Reconcx I know its a great deal and all but, im going to have to turn down your offer, you probly wouldnt wanna ship to me n e wayz i live in canada, im probly gonig to get the Abit 9550, i would liek to know which ram and the specs that each company uses first becasue id hate to get stuck with sum non-overclockable ram, im hoping for 4ns ram. maybee we could put together a 9550 ram chart. :)
 
the lower number the better, hynix i think is best. the lowest mem i've seen is 2.8ns Hynix on a 9550.
 
which one was that? we should put together a chart u know like i know that the HIS 9550 IFAN VIVO has 4ns hynix, we need to ask ppl whi post in this thread what their 9550 is running in ternms of ram, i think the Asus 9550GE runs 4ns. WE NEED INFO PPL!! POST THE RAM SPECS OF YOUR 9550!!
 
I heard of 5.0 and 4.0 samsung for Asus. i know for sure the Gamers edition of the 9550 has 4.0 samsung ( i have it myself ).
Others i dont know xactly
 
the hynix 2.8ns was on none other than mine =)
 
What ram would be on this Abit card? http://ncix.com/products/index.php?...anufacture=ABit
Also i heard, DON't QUOTE ME ON THIS!! that the Abit 9550 GURU, not the one above thats just a plain 128 meg 9550, but the GURU version with all the fans and heatsinks, run 3.3 or 3.6ns BGA ram. But id realy liek to know what the one in the link has cuz im just about ready to buy that card :D
 
can someone tell me high how they got the core and mem when overclocking the 128 i know how high the 256 goes just wanna see the dif >X

9550 sapphire defauilts core = 200 mem = 250
oc core = 250 mem = 320

.o.k first of all ur question is hard to understand bcuz ur english is crap, second of all its a stupid question? if ur gunna post stupid questions dont post at all. Now id liek to know what ram the Abit cards have on them, the 9550 ragular and the guru version.
 
how bout if your going 2 be a rude a$$hole then dont replay or maybe it because u have no life and all u got is free time on ur hands to be rude u realize ignorance is bliss and your pretty ignorant now go find urself a life in ur meaningless place in the world and leave people alone k thats nice
 
GUYS! KEEP THE THREAD CLEAN. TAKE IT ELSEWHERE. I DIDN'T START THIS THREAD FOR PEOPLE TO FLAME EACH OTHER.

ownage187, your question isn't specific enough, what are you talking about exactly?

Inteleron, i can't find the answer to your question cause ABIT conveniently didn't put that in their specifications chart on their website.. the only way to know exactly is to find someone who's got that card, and get the ram serial off of it.
 
im asumeing that a simple your question isnt clear enough woulda worked,

What i meant is What is the core clock and the mem clock of the 9550 128 meg card (as in speed for those that dont understand)

cause i already know what the 9550 256 meg is

there was no need to be rude i was more then likely drunk when i wrote it and didnt realize that i didnt make it clearly >X

Meaning 200 core 250 mem defauilt
 
default is 250/200x2.

your overclock rate is based on the type of mem you have.. an approximation would be
suppose you have 2.8ns ram on your card, then it would be 1000/2.8 = ~357(x2). but that is strictly hypothetical and doesn't mean your card can reach that high. It also doesn't mean it won't surpass it either. Voltmods also change variables here too..
 
Yah w/e >X that means :rolleyes: thanks for your reply, i guese ill have to jsut ask arround but im pretty sure its 4ns, im also hunting arround for the Guru version with 3.3ns ram. :D
 
Someone has tried this pencil Vmod? it appears you can get OC much higher!!
(U have to draw a line between at those green ] for Vmod VPU and Memory)

Flashed BIOS on my Ge-Cube 9550

Hi, I've also tried to OC my Ge-Cube 9550 5.0ns hynix using atitool, but in every second game I got VPU recovers, even running on much lower clocks than those which still worked without artifacts. So i've decided to try a bios flash (the thread with gecube as non flashable I've noticed today :( ). Got GEcube 9600pro 398/203 hynix one and flashed it. Everything is working ok except that: 1) after resume from sleep/standby state the monitor screen stays black = need to cold reboot. Could this be caused by the new bios? What woul you recomend me to do to fix it? (don't have pci vga card to risk flashing more than necessary).
Please help, anybody.

Thank you very much
Rich CZ

Slow in Real mode after flash

I just bought an ASUS A9550GE 250/200 5.0ns and applied 9600pro bios on it. I'd tried powercolor and Gecube bios at 400/200 but having the same following problem:-

The screen was very very slow during start up (I mean the words displayed). If went into bios, it took about 5 seconds to display a page (because words come up one by one like typing). In windows everything was normal, detected 9600 series and recorded 11xxx in 3dmark01 without artifact (99xx with 9550 bios). In short, the card had no problem in windows mode but very very slow during startup. **** in real dos mode everything is ok; just the starting got problem.

Please help, thx~
