I think we're pretty much screwed on OCing the card. It's a cheap card for a reason. I'm still impressed by getting a card that is sometimes almost half the price of the 6800GT.

yea, i agree. i got mine for 200. it'll play the games i play now for a while

If you're overclocking and getting a 20% increase in your 3dmark score then you should definately see a significant increase in your BF2 framerate. If not, you're doing something wrong.

right... .and what would you suggest that would be that I am doing wrong?

 

[M0RPH]

I think the increase in BF2 performance is there, not sure why your not seeing it. I'd suggest you find a more systematic way to measure your BF2 framerates. Record a demo and run it three times at stock and overclocked speeds to get an average.

niggles may be CPU limited but in any case even if o'erclocking does not significantly increase the framerate, doing so may allow higher quality settings wi'out reducing it. However, be wary of exceeding physical system memory capacity as paging will make the game less playable than the framerate may suggest.

Wow...and I thought my X800Pro would be soundly beaten by an X800XL. I easily get 5500 in 3DMark 05. When I overclock to the max, I get around 5800. At 5500 I'm running the card at 540 core and 1020 memory with the default 12 pipelines open. I wish I could unlock the remaining pipelines!

agree'd, I get about 5800 in 3dmark05 with 580/550 overclock (475/450 stock)... Shouldn't X800XL be clocked faster than the Pro out of the box???? or am I wrong?

 

[niggles]

have a look at this chart, it shows the clock speeds, but more importantly it shows that the pro has 12 pipes while the xl has 16: http://graphics.tomshardware.com/graphic/20050705/index.html#_the_contestants

The stock coolers are terrible IMHO. With the Artic Silencer, I've been able to lower my temps almost 30c and give me a little boost in my oc(see sig). If you plan to upgrade down the road, I would pick-up a Zalman VF700(I wish I did). With good case cooling, it'll cool just as well or better than the Artic Silencer and you'll be able to transfer it to your next video card.

I thought it was less a heat issue and more a simle yield issue causing the instability in overclocking. Not saying that heat is not an issue, but I didn't think it was *the* issue.

 

[Capt Caveman]

I didn't imply that it was "the" issue. But adding 3rd party cooling allowed me to add probably an extra 10mhz. I apologize if I gave that impression.

Ive got my powercolor x800xl with the extra connector at 425/550 with the stock cooler.

Using a Connect3D X800XL (no extra power connector) and Artic Silencer I am able to run 450/571 with 37 idle and mid 50's after gaming for a few hours (Fan override @ 100% when temps go above 40). Also using ATi Tool 0.24.

I too couldn't get much of an overclock without artifacts with the stock cooler, and temperatures were insanely high.

EDIT: Forgot to mention that I applied artic silver 5 to the GPU and ram when installing my Artic Silencer, may have helped a little.

 

[Auric]

I wouldn't bother with the expense of an after-market cooler in the hopes of o'erclocking more 'cause any difference will be negligible and certainly poor price/performance wise. Better to spend the extra $25 on the next faster model instead. A VF700 can reduce noise, however I was impressed with the original considering the form factor limitations (single slot)... sporting a Cu base, heatpipe, Al fins and memory cooler. If I was doing it over I would try removing its cover and fan and the adjoining rear slot cover and using a 92mm Panaflo to blow air across the length and out the back (RPM controlled or limited in some manner).

445/550 out of the box with this this basic gigabyte model

Mainly played with core settings - I can get it up to 450ish safely...460ish locks up instantly

Haven't really played with memory yet but I upped it to 570ish in ATT and let it run artifact detection and it looked fine but I still need to play around with it

Forget about OC'ing... my ATI X800 XL gets up to around 80 degrees at STOCK (and I have tons of airflow). I think it's really heating up my case temp too so I've been considering throwing a Silencer on it and pushing some of that heat out the back.
