ATI X1800 XT OC limits/?

post #1 of 3
Thread Starter 
Greetings and thanks in advance for any and all help
I have a Vintage AH-1 barebones, 600w asus power, 2gb 3200 ram, 250 gb seagate, amd athlon 64 x2 4200+ manchester, audigy 2 zx, and the great ati x 1800 xt 256 mb. love the card - want more outta it. The ATI TOOL wont recognize it as being supported by windows for some reason? so i downloaded Systool v1.0 build 728. That doesnt rec. my mobo but it does see my AT Card. This is what i saw about the card (didnt specifiy if for 256mb, but based upon the specs below and what my diag says i think its for the 512)
"Currently, the standard clock settings for the Radeon X1800 XT are 625MHz for core and 750MHz (1500MHz data rate) for memory. Because ATI is experiencing good yields on the Radeon X1800 XT core, it is allowing boards to be overclocked to 700MHz core and 800MHz memory (1600MHz data rate). In the document, ATI also indicates that standard clock settings are often set at conservative speeds to produce the highest output yield possible. "
So with that said, the Systool will let me increase/decrease my core and memory values. Upon diag scan - Core is set to 594.0 and Memory is set to 693.9.
What SAFE numbers do people think i can push?

hey! welcome to the boards.
i did a lot of testing with my x1800xt to see what its maximum speed was that it would run stable on for hours on end. I found 694/798 to be my magic number.
Anything over this kept crashing in 3Dmark tests and would give me artifacts every now and then.
ive been running it at this speed for the past 5 months with no problems.
hope this helps.

hey- omg you rock so much. thanks!!
our systems are pretty much the same..
the mobo is dif. but same cpu, and same vid. only difference is im running 600w JUST becuase i caught an awesome sale and i didnt know what else i was gonna need to add to the system.
either way - i think i might be tooling around on it today and ill try it out.
will post when i get it done..
thanks again!

p.s. any luck with oc the cpu? (i wanted to save space and just add here as opposed to making a new thread) i have a bunch of progs that allow me to change the fan voltages and temps and stuff. im not sure what to do and wanna go slowly. after reading that report of ati giving an ok about ocing, i figured what the heck maytbe ill try the whole system
