ATI-Tool success - Atlantis 9800

[Wayne Youngman]

Hi,

I bought my Sapphire ATLANTIS 9800 (3.3ns Samsung) last august, never
bothered overclocking it, but I just got my head around *ATI-Tool* . What a
nice tool that is. . .I read up allot on how to use it and set the testing
to stop after 3600 seconds error free. . .and then left it overnight to run.
.. .

STOCK GPU 325MHz
ATI-Tool O/C GPU (01): 424MHz
ATI-Tool O/C GPU (01): 426MHz

STOCK MEM 290MHz
ATI-Tool O/C MEM (01): 346MHz
ATI-Tool O/C MEM (02): 347MHz

ATI-Tool O/C GPU/MEM (01): 424MHz/343MHz

The board is still running the stock HSF but get very hot (65-70°C) so I
will install proper cooling soon.

Do you think I can get much higher (with better cooling or BIOS flash?).

I'm very pleased to O/C the GPU by an extra 100MHz, that puts it ahead of
the 9800Pro and the 9800XT but I am wondering what is the max I can expect
from the Samsung memory. I heard if I flash to the 9800Pro BIOS I can get
higher overclocks on the memory?

Nopt really as you're already well over XT specs.

Hi,
I thought the XT ran allot higher on the memory? (more than 343MHz/686DDR)

412/700 but it depends on manufacturer.

Hi again,

well things are going well, up to nearly 450MHz Core speed (from 325Mhz) now
I'm just trying to break 350MHz (700DR) on the memory. Having fitting the
ARCTIC cooler I was able to gain about 20-25MHz on the Core (artefact free!)
but it has done zilch to cool my ram?, in fact I think my BGA Ram is running
a *tad* hotter? Don't know why? would have thought the ARCTIC cooler would
have *drawn* away some heat from the PCB. . .

So I still got a few things to test out:

a) Flash the 9800 using a 9800Pro BIOS
b) Epoxy some Tweakmonster BGA-Ramsinks onto memory
c) test out some newer drivers (CAT4.5 etc) as I am still using CAT3.7

The Shim on my card was lower than the GPU by about 1mm so I didn't have to
take it off.
